06:18.53sorphinT0mW: evenin gramps
06:19.03T0mWgood morning
06:19.23T0mWsome of us live on a different schedule than the others do
06:19.24T0mWeh?
06:19.25T0mWheh
06:19.28sorphinT0mW: ever scoped out video?
06:19.33sorphinindeed
06:19.36T0mWnot really
06:19.46sorphink
06:20.13T0mWoh, computer show in the morning, I need a case
06:20.30T0mWI have boards, need case to put them in
06:21.12sorphinheh
06:21.13sorphinyeah
06:21.21sorphingot a board i need a case for too
06:26.49T0mWI need someplace for secondary DNS
06:27.19T0mWsince the ISP closed, I've only primary and that is causing problems with email
06:27.54T0mWThe system is on Sprint and the T1 keeps developing problems, plus the local electric company sux
06:28.13T0mWseems everytime we get a storm the freaking power goes out!
06:28.45T0mWit is not conducive to keeps a server on the net with 5 9's
06:28.45T0mWhe
06:28.47T0mWheh
06:29.11sorphinT0mW: secondary dns eh?
06:29.18T0mWwe should be happy they are up over 90% of the time
06:29.33T0mWI have another location
06:29.40sorphini was gonna say
06:29.42T0mWon another network
06:29.45sorphini secondary for a few people
06:29.57sorphinmy downtime is generally 0
06:30.48T0mWheh
06:31.00sorphinjust let me know (no charge :P )
06:31.13T0mWI'll have to get the info together, I've got like 5..6 domains on that thing.
06:31.20sorphintaht no biggy
06:31.33T0mWthese are no charge domains, just stuff for people I know.
06:32.32sorphin22 for the host (he's a friend of mine)
06:32.50T0mWI've got nine
06:33.04sorphinand 3 of my own that i primary and secondary
06:33.15T0mWsorphin: you need a secondary?
06:33.18sorphinwith an additional secondary in frisco
06:33.23sorphinsure
06:33.31T0mWok, we can swap then
06:33.36sorphinthat'll cover east and west
06:33.36sorphinehh
06:33.38sorphinyeah
06:33.55T0mWI'll get the info together
06:33.58sorphinok
06:34.06T0mWthanks
06:34.42sorphinwhat's your primary server's ip?
06:34.54sorphini'll toss it in the transfer allow list
06:35.33T0mW216.182.48.170
06:35.41sorphink
06:36.03sorphinheh
06:36.08sorphininteresting hostname/domain there
06:38.00T0mWwhere is that?
06:38.04T0mWbeastbox?
06:38.06sorphinyeah
06:38.22T0mWit was, now we have workstations more powerfull
06:38.34sorphinnod
06:38.55sorphinonly 1 domain you'll have to secondary, the other 2 aren't critical so i soley handle those
06:39.04T0mWok
06:41.06T0mWwhat's the ip?
06:41.24sorphinjust sent you mail at the email you /msg'd
06:41.28T0mWk
06:41.43T0mWgot it
06:41.47sorphinso i see :)
06:43.13T0mWI have a hell'va conflict there with beastbox, I have it both as an external name and internal name.  I will straighten that out once I install the new server
06:43.25sorphinnod
06:43.33sorphini need to segregate my dns
06:43.59sorphin*.rfc.captainrock.com for internal
06:48.10MonMothamy solution to that (since you invariably have stuff behind NAT these days) is to create a real domain for publicly addressable stuff (example.com) and then make another one that's fake for internal stuff (I use example.lan)
06:48.12T0mWok, I've got your record
06:48.20sorphinT0mW: ok
06:48.30MonMothaHopefully ICANN/IANA won't go and make the .lan TLD (it would be rather dumb for them to)
06:48.31sorphinm0n: heh, nat?
06:48.54sorphinthat's the only nat i use
06:49.06MonMothaunfortunately, at my home, NAT is unavoidable
06:49.35MonMothamy cableco won't let me buy address space, DSL is unvailable due to fiber at the street (I coudl get IDSL..oh boy), and a "real line" is out of the question price wise
06:49.45MonMothaT1 to Frame Relay is >$400/mo w/ a /28 in my area
06:49.47sorphinheh
06:49.55sorphinwhat about fiber at the street then?
06:50.11MonMothatelco refuses to provide any consumer friendly services on it
06:50.16sorphinah
06:50.23MonMothaI could get a fscking OC-3 to my house if I wanted to pay for it, but no consumer services are available
06:50.44MonMotha(I seriously called the local telco up and asked what was available from them, and they suggested a T3)
06:51.08sorphinheh
06:51.08MonMothaI can do ISDN/IDSL or T carrier from the telco
06:51.16MonMothaif I could get DSL, I'd look into speakeasy
06:51.25sorphinsounds like you live in the wrong place man ;)
06:51.28MonMothathey'll do pretty speedy DSL with routed address space for ~$120/mo
06:51.51MonMothayeah, though that's my parents' place.  You'll notice from my current address that I'm a student
06:51.53sorphini almost had speakeasy
06:51.53MonMothaI have a real IP here
06:51.56sorphinbut they mucked up
06:52.04MonMothaunfortunately, the school won't route you off a subnet
06:52.04T0mWsorphin: did you get my zones ok?
06:52.10sorphinthey didn't keep a leash on covad
06:52.16sorphinT0mW: hold on, putting you in
06:52.32MonMothayeah, they seem to not handle Covad very well, and Covad doesn't exactly provide great service
06:52.47MonMothaonce it's up, it seems to work fairly well.  I have a client who hosts her email/web in house on speakeasy
06:52.56sorphinwell
06:53.00sorphincovad sat on their hands
06:53.05sorphinSBC delivered a loop
06:53.09sorphina month later
06:53.11MonMothawe just have a single static IP and do NAT for LAN access to the internet.  No need to pay for anything more
06:53.14sorphinspeakeasy finally prodded covad
06:53.16sorphinwho woke up
06:53.21sorphinoh (says SBC)
06:53.25sorphinthat loop we gave you
06:53.38sorphinit's 1000 feet too long, sorry (we ran it wround the block twice 1st)
06:53.46MonMothahaha
06:54.04sorphinMonMotha: i later got sbc dsl when they dropped fiber and put in remote dslams
06:56.05MonMothayeah, I have fiber at the street, which will be great if SBC ever gets off their collective asses and does FTTP
06:56.07*** join/#elinux cbrake2 (n=cbrake2@cpe-24-166-121-47.neo.res.rr.com)
06:56.17MonMothahowever, DSL requires copper
06:56.21sorphinuhh
06:56.28sorphinsort of
06:56.49sorphinOC3
06:56.50sorphinwoo
06:57.22MonMothayeah, but this box at the street only serves like 15 houses.  Hardly worth putting any kind of new equipment in there since maybe 2 would get DSL (especially since most interested people already ahve cable)
06:58.43sorphinheh
06:58.48sorphini'd never use a cable modem again
06:58.50sorphini'd rather use dialup
07:00.17MonMothaeh, the cableco we have does a decent job
07:00.26sorphinT0mW: got em
07:00.30sorphinMonMotha: charter
07:00.32T0mWthanks
07:00.36MonMothaah, now I see why
07:00.38sorphinT0mW: right
07:00.41MonMothathis is Brighthouse/Road Runner
07:00.54sorphinMonMotha: had brighthouse when we were in orlando in the hotel
07:00.58sorphinheh
07:00.59MonMothawhich I've heard suck in some places, but around Indianapolis they do a good job
07:01.08sorphinthankfully the timeshare, has satellite :P
07:01.35MonMothayeah, they do make you buy basic cable to get the cable modem. Bastards
07:01.38MonMothaour cable bill is >$100/mo
07:01.42sorphinheh
07:01.50sorphinsux0rs to be you
07:02.03sorphinheh
07:02.15sorphinso my phone bill is hefty w/ the sat, dsl and phone (no LD)
07:02.19MonMothabut that's not bad for basic (+ "family pack") cable and a 5M/512k cable modem w/ 2 IPs (dynamic, unfortunately)
07:02.33sorphinnod
07:02.51MonMothathey charge out the ass for that second IP: $10/mo
07:03.00MonMothawe could probably drop it now that the work VPN supports NAT traversal
07:03.08sorphinerm
07:03.08sorphin95
07:03.28sorphin5 usables (one gets taken for the head + 1 broadcast and 1 network)
07:03.38sorphin3.08M/512k
07:04.26sorphinheh
07:08.00MonMothasorphin: Kim Brand.  Yeah, he delegates that to me
07:08.10MonMothaand pays for it too
07:08.17sorphinheh
07:08.23MonMothaI do contract work for him
07:08.28sorphinah
07:08.30MonMothaI need to send him a zonefile for that
07:10.36sorphinMonMotha: now tha ti know you're awake
07:10.42sorphinever scoped out video? :P
07:11.03MonMothayes, actually
07:11.38MonMothait's kinda a pain in the ass if you don't have a scope with special video sync functions
07:11.43sorphinMonMotha: this new box.. has the video hidden on a 39 spot header... jbevren mapped hsync and vsync and 1 video
07:11.48MonMothaespecially in combined sync/video systems like NTSC
07:11.55sorphinthis is vga
07:12.02MonMothaah, that's a little easier
07:12.13MonMothaunless it's SOG, which you said it isn't
07:12.18sorphinhere's what he gave me so far
07:12.34sorphin<PROTECTED>
07:12.34sorphin1 2 3 4 5 ....

07:12.49sorphin2-6 i'd found are grounded
07:12.55MonMothawhat's 6?
07:13.14sorphinso that nukes the whole R-Gnd-G-Gnd-B-Gnd theory
07:13.17sorphinjust told you
07:13.22sorphin2-6 are gnd'd
07:13.31MonMothano, what's 6?  you have 1-5, a-e
07:13.38sorphinuh
07:13.46sorphinwould you rather i show 39 pins?
07:13.53MonMothaoh, ok
07:13.57MonMothait continues
07:13.59sorphinright
07:14.00MonMothaI didn't noticed the ...s
07:14.04sorphinhehe
07:14.04sorphins'ok
07:14.43sorphini'm guessing somewhere in 2-6 are sync gnd, red gnd, blue gnd, green gnd, and gnd
07:15.03MonMothathose are frequently just all tied together
07:15.07sorphinright
07:15.10MonMothausually causes no problems
07:15.14sorphinright
07:15.30MonMothawhat's your objective here?
07:15.34sorphinheh
07:15.47sorphini need the other 2 videos
07:15.54MonMothaok
07:16.09sorphinfbsd won't instlal via a serial port because their installer blows and has a bug
07:16.13sorphinso i need to use video
07:16.17MonMothawhat kind of scope do you have?  digital storage or analog?
07:16.25sorphinfbsd is needed for JunOS
07:16.29sorphinanalog tektronics
07:16.36MonMothaah, like mine.  What kind of bandwidth?
07:16.40sorphin100mhz
07:16.47MonMothahum, now I'm curious, what model?
07:16.51sorphinhold
07:21.42sorphinsorry
07:21.44sorphin300mhz
07:21.53sorphinTektronics 2465

07:22.31sorphinjust 2465 300mhz
07:22.40sorphindual channel
07:22.46MonMothaok, not the same as mine then
07:22.52MonMothadoes it have a separate sync input?
07:25.23*** join/#elinux cbrake2 (n=cbrake2@cpe-24-166-121-47.neo.res.rr.com)
07:25.30sorphinok, scratch that.. man shows how long it's been since i've had it out
07:25.32sorphin4 channel
07:25.40MonMothaeven easier
07:25.40sorphinZ input on the back
07:25.43sorphingate output
07:25.59sorphincalibrated 2 years ago
07:26.00sorphinheh
07:26.02MonMothaput the hsync on ch. 1.  Is it high or low most of the time?
07:26.11MonMothashould be TTL level or similar (digital at least)
07:26.18sorphini dunno
07:26.29sorphinhaven't hooked up yet
07:27.05sorphinfyi, i only have 2 probes btw (10x)
07:27.34sorphineven bought the svc manual for the thing
07:27.45sorphini really need to set up a damn bench down here
07:27.58MonMothaI was planning on talking you through it
07:28.01sorphinoh
07:28.23sorphincan you gimme a few then to set the scope up?
07:28.31MonMothasure
07:28.33sorphink
07:28.34sorphinbrb
07:28.40MonMothaI'm working on a paper for a tech comm class, so I'll be up for a while
07:29.29sorphink
07:33.01sorphin2 probes gonna be enough?
07:33.02sorphinheh
07:35.58MonMothayes, more would be nice
07:36.15sorphinhrm
07:36.17MonMothathough if you have any BNC connectors laying around, you could just use wire for the sync signals
07:36.35sorphinlemme see if my remaining probe from school still works
07:37.00MonMothait's not a big deal
07:37.03MonMotha2 is fine
07:37.27sorphink
07:37.33sorphinwhat should i set the scope at?
07:38.32MonMothastart off at 50-100uSec/div horizontal, 0.25V/div vertical on your probe line, 5V/div vertical on the sync line
07:38.34MonMothatrigger on sync
07:38.46MonMotharising or falling edge is fine for now
07:39.04MonMothahook the probe that isn't on sync up to the known video line
07:40.37sorphini don't have a sync line on the scope
07:40.48MonMothait should sync on one of the input channels
07:40.57MonMothathere's probably a switch to pick which one
07:41.04sorphini meant for your 5V/dev
07:41.09sorphinright
07:41.24MonMothaoh, HSYNC from the video
07:41.28sorphinok
07:41.30MonMothaput that at 5V/div
07:41.34sorphinok
07:42.30MonMothaok, you should see some pulses on the sync line (ignore the video for now)
07:42.42MonMothait'll idle either high or low and pulse every once in a while to the other level
07:43.37sorphinhold
07:46.22*** join/#elinux kergoth_ (n=kergoth@c-24-118-219-25.hsd1.mn.comcast.net)
07:46.40sorphinerr
07:46.43sorphinthis is ulgy
07:46.44sorphinugly
07:48.03MonMothathe sync signal should be very square
07:48.26MonMothais the scope triggering?
07:48.46sorphinlooks more like noise spikes
07:49.45MonMothaah, decrease the horizontal time/div (make it faster)
07:50.15MonMothathe sync pulses are very short compared to the line scan tim
07:50.16MonMothae
07:51.24sorphinits hard to make them out of this
07:52.53MonMothayou sure you're looking at the hsync signal and not the video signal?
07:53.59sorphinok, i switched to DC coupling and i can see them.. they're noisy but i see em
07:54.48sorphinthat's it
07:54.52MonMothayes, make sure everything's on DC coupling
07:54.52sorphincuz i measured between
07:55.02sorphinit's about 31.7khz
07:55.05sorphinok
07:55.15MonMothawell, there will also be blanking intervals on the video
07:55.37MonMothathat would look like noise with periodic not-noisy low spots at this resolution
07:55.50sorphinwell, i'm looking at the sync atm
07:55.58MonMothaok.  Is hsync normally high or low?
07:56.13sorphinit's bigger at the top of the square
07:56.21MonMothaso normally high, sync active low
07:56.26sorphinso normally high
07:56.27MonMothayeah
07:56.34MonMothaset your trigger for rising edge
07:56.49sorphinuhh
07:56.56MonMotha(it may already be there)
07:57.10sorphinthere's only + slope and - slope
07:57.18MonMothayeah, that's rising and falling edge, respectively
07:57.23sorphinok
07:57.28sorphinalready on rising edge
07:57.30MonMothaok
07:57.44MonMothacrank the horizontal faster until you've got 2-3 sync pulses on the screen
07:57.55sorphindone
07:57.59MonMothamaybe even less than 2, as long as you've got one full period
07:58.04sorphinonly took 1 turn
07:58.06sorphinok
07:58.18sorphinhrm
07:58.21MonMothaok, put the sync at the bottom of the screen (shoudl be only 1 division high) and fill the rest of the screen with your video signal
07:58.25sorphinless then 2
07:58.48sorphingives me: ----|__|----
07:58.51sorphinthat enough?
07:59.01MonMothaoh, your scope does center screen trigger...
07:59.03MonMothainteresting
07:59.08MonMothaset it to falling edge
07:59.15MonMothaI thought only digital scopes did that
07:59.15sorphinok
07:59.17sorphinthere we go
07:59.23sorphingot a full period now
07:59.23MonMothayou should have __------------__
07:59.33sorphinwell
07:59.44MonMothaor maybe -__---------__-
07:59.50sorphin__-----------------__----------
07:59.54MonMothagood enough
07:59.56sorphink
08:00.17MonMothabring your video up and adjust the vertical so it fills the remainder of your screen (the signal should be around 1Vpp)
08:00.24sorphink
08:01.09sorphinok
08:01.14sorphinthe video really looks like crap
08:01.44MonMothait should look like __~~~~~~~~__~~~~~~, where ~ is a big amount of extremely high bandwidth variation between about 0-0.7V (or maybe 0.3-1V)
08:01.53sorphincan't make out much
08:01.56MonMothadepends on what's being displayed of course
08:02.01MonMothayou shouldn't have to
08:02.27MonMothajust so that you see what video looks like
08:02.39MonMothanow just take your probe and probe each remaining pin looking for other video signals
08:02.53MonMothayou won't knwo which is R, G, and B, but you'll get your three video lines
08:03.04MonMothathen hook them up to a monitor and try different combinations until the colors are right
08:03.14sorphinwell, i can't really see enough of video to give me a good 'thing to look for', it just looks like noise
08:03.14sorphinheh
08:03.23MonMothayeah, but nothing else is likely to look like noise :)
08:03.24sorphinbecause i have it dialed so i can see the sync
08:03.32sorphinokie
08:03.40MonMothawhat you're looking at is one full line of video (actually, a bunch on top of each other)
08:03.55MonMothaif you want just one line of video (at the expense of a very dim trace), you can replace HSYNC with VSYNC
08:04.03MonMothayou'll get just one line of video (the first one)
08:04.15MonMothaif you want the nth line, you need some external hardware
08:04.29sorphini just want video so i can see what the hell to look for
08:04.30sorphinheh
08:04.59MonMothavideo basically looks like __~~~~~~~__~~~~~~~__~~~~~~~~__...
08:05.17MonMotha__ is a very nice DC blanking level (usually -0.3 or 0V), ~~~~ is the active video.  For VGA it's 0.7Vpp
08:05.23sorphinwell why am i keeping the sync on the screen?
08:05.34MonMothareference mostly, you can get rid of it
08:05.39MonMothayou need it for the trigger, still
08:05.44sorphinright
08:05.49sorphini'm not disconnecting it
08:05.51MonMothaso you can't unhook the probe
08:05.56sorphinjust getting it out of the way visually
08:06.03MonMothawhen I did this, I left it at th ebottom 1div of my screen
08:06.12sorphinadjusting the time won't affect my trigger, will it?
08:06.28MonMothano, but going any further won't give you any useful info
08:06.39sorphinheh, this is the 1st time i've really gotten a use outta teh scope
08:06.40sorphinheh
08:06.42sorphink
08:06.43MonMothathe reason it looks like noise is because there are multiple lines drawn on top of each other
08:07.08sorphinuh
08:07.10MonMothaif you want to get really really fancy, it's actually possible to rig a scope with X-Y mode and a Z axis input as a monitor
08:07.14sorphinlotsa sines
08:07.30MonMothathere shouldn't be any pure sines
08:07.40MonMothain fact, the output should be very quantized
08:07.58MonMotha(if you zoom in on the video signal further, which I couldn't do with my 100MHz scope)
08:08.54sorphinah
08:08.59sorphinwas noise on the squares
08:09.04MonMothaoh, yeah
08:09.13MonMothait'll ring since your scope is Hi-Z and it's expecting a 75ohm termination
08:09.33sorphinah
08:09.35MonMothaif you have a 50 or 75 ohm terminator you can throw on there, that would fix it
08:09.47sorphinheh, nope, fresh out
08:09.49MonMothawould also give you correct levels (you should be seeing 2Vpp I guess, since you're working into Hi-Z)
08:09.55MonMothayou don't have any of the old Thinnet gear?
08:09.58sorphinnope
08:10.08MonMothaI just use a BNC-T and a 50ohm terminator from my old thinnet stuff.  Ugly, but it works
08:10.08sorphinand you're right
08:10.13sorphini was seeing 2v P-P
08:10.31MonMothamakes sense.  There's normally a 2:1 voltage divider between the source impedance and the monitor termination
08:10.45sorphink
08:11.05sorphinthere's 12v and gnd on this header to he mentioned
08:11.06MonMothait's Source>----/\/\/\/\/\-----<Monitor>-----/\/\/\/\/\----<GND
08:11.06sorphinheh
08:11.17sorphinright
08:11.28MonMothawell, putting 12V on your scope won't damage it, even on the more sensitive vertical settings
08:11.34MonMothait would, however, be rather detrimental to your monitor
08:11.43sorphinhehe
08:11.44sorphinright
08:11.58sorphinhence doing this
08:12.01sorphinso i don't ;)
08:12.05MonMothareminds me...I need to rig up my scope as a monitor some time
08:12.18MonMothait's not too tough
08:12.31sorphinwell, a probing i go i guess
08:12.50sorphinso if i trigger off the Vsync instead of Hsync
08:13.04sorphini'll see a slightly cleaner video (since it's 1 line) ?
08:14.02MonMothayes, though there are some caveat
08:14.02MonMothas
08:14.15MonMothaone, the video will be very dim (since it's only scanning a line once every frame)
08:14.15sorphinok
08:14.19sorphinright
08:14.23sorphinthat's dealable
08:14.29MonMothatwo, you might see nothing at all, if the first line is constant black (not uncommon)
08:14.43sorphink
08:14.46MonMothadepends on how easily you can tell the blanking level from the black level
08:14.51sorphinguess i'll deal with noise :P
08:16.01sorphinhmm
08:16.06sorphinsees a might be a video too
08:16.13sorphinlotsa squares
08:16.25sorphinman
08:16.27sorphini can see these
08:16.35sorphinlot cleaner than pin 1 was
08:16.36sorphinheh
08:21.26MonMothathen it's probably not video :)
08:21.40MonMothait it's just a digital signal, it's not video
08:22.42sorphinwelp
08:22.45sorphinprobed everything
08:22.52sorphinfound gnd
08:22.55sorphinfound +v's
08:23.07sorphinonly 2 "videos" are those 2
08:23.13sorphinthen the 2 syncs
08:23.38sorphinthey mention in the manual that this header is where video is configured, heh
08:23.47sorphinand jbevren got video off pin 1 to his monitor
08:24.15sorphini don't hink my monitor will take video on 1 channel tho.. tried the other day.. saw nothin
08:24.47MonMothawell, then I guess you have your RGB
08:24.53sorphinuh
08:24.55MonMothayou did connect up the syncs, right?
08:25.03sorphinhow do i have RGB?
08:25.08sorphini have maybe R and G
08:25.14MonMothaoh, so there's only two videos total?
08:25.16sorphinonly 2 video lines found
08:25.24MonMothaincluding the one you started with?
08:25.26sorphinyes
08:25.37MonMothawell, is it possible that it's just monochrome video?
08:26.07sorphinshouldn't be, they tout it as vga, and this has a chips and technologies video chip w/ 4M ram
08:26.23sorphinhardly worth all that for mono
08:26.57MonMothado you know what it might be attempting to display on the screen?
08:27.11sorphinbtw, when i said that other square was 'cleaner', it still had tons of overlays
08:27.14sorphini just did some tweaking
08:27.16sorphinyes
08:27.19sorphinthe bios menu
08:27.24sorphini'm sitting in the bios atm
08:27.34sorphinvia the serial agent
08:27.47sorphinbut i have 'video at preboot' turned on
08:27.58sorphinso there's video output
08:28.38sorphinanyways
08:29.28MonMothawell, I guess I'd say try hooking things up to your monitor
08:29.36sorphinheh
08:31.08sorphinerr
08:31.20sorphinshouldn't vsync be a much smaller number? :P
08:31.50MonMothain terms of frequency? yes
08:31.54sorphinhrm
08:32.03MonMothashould be 60 for normal VGA
08:32.10sorphinscope shows it the same as the damn hsync
08:32.32MonMothaare they maybe both composite sync?
08:32.53MonMothaback off the horizontal until you can see a whole line
08:32.55MonMothaer whole frame
08:33.11MonMotha~2ms/div
08:33.49MonMothacomposite sync would look like:  ------_---------_--------_------____-___-____--------_-------_-------
08:34.06MonMothawith there being a LOT more -----_----- than _____-_____
08:35.06sorphinok
08:35.16sorphinhsync is like we said initially
08:35.39sorphinvsync show more _____--_________--________--_______
08:36.13sorphinscope still says it's in the 31khz range
08:36.18MonMothaso vsync is the inverse of hsync?
08:36.26sorphinwould appear so
08:36.28MonMothaare they the same thing just inverted?
08:36.29MonMothahum...
08:36.30sorphinand a higher voltage
08:36.38MonMothathat's...odd
08:36.53MonMothathey're normally both at TTL or CMOS logic levels (frequently very nice 5Vpp square waves)
08:36.56joe_bleauSwitch probes...maybe the attenuation is off on one channel?
08:37.11MonMothadoes it differ by a factor of 10?
08:37.20MonMothahe doesn't have any more probes :)
08:37.24sorphinhsync is 1v P-P
08:37.34sorphinvsync is...
08:37.34MonMothahsync should normally be much larger than 1Vpp
08:37.49joe_bleauRight, but if one is a 10x and the other a 1x, swapping the two will show it...
08:37.49MonMothaespecially into a Hi-Z load
08:37.52sorphin5v P-P
08:37.54MonMothatrue
08:37.58sorphinuh
08:38.03sorphinthey're both 10x probes
08:38.08MonMothasorphin: sometimes that messes up
08:38.16MonMothaespecially on scopes that autodetect and adjust for it
08:38.19joe_bleauAnd you know the scope attenuators are ok?
08:38.26sorphinheh
08:38.41MonMothamine doesn't do that, it just has two markings on the vertical: 1x and 10x
08:38.52joe_bleauActually, could his 'hsync' be a color signal?
08:39.04MonMothapossibly
08:39.12MonMothaand vsync could be composite sync inverted
08:39.26MonMothait's often hard to see composite sync without usign a delay trigger
08:39.38joe_bleau(BTW, great ascii art on the composite, MonMotha)
08:39.41MonMothayou can't get the horizontal res high enough to see the vsync blip without shoving the end of the frame off the end
08:39.56sorphinok so......
08:40.06sorphincould this be SOG? :P
08:40.11MonMothathat's also possible
08:40.43MonMothaSOG looks like ~~~~~_~~~~~~_~~~~~~-~~~~_~~~~_
08:40.50MonMotha_ is hsync, ~~ is video, - is vsync
08:40.51joe_bleau1V p-p on a I/O connector sure sounds like an analog signal to me, which points towards a video color line
08:40.59MonMothayeah
08:41.11sorphinwell
08:41.18sorphinbonehead pinned thse as the sync lines
08:41.24sorphinand got video w/ them as sync lines
08:41.27sorphinand pin 1 as a video
08:41.28MonMothasorphin: try hooking the supposed vsync up to the hsync line on a monitor, and the supposed hsync and video lines to the RGB inputs
08:41.35MonMothasee if it will sync as composite sync
08:41.54sorphinMonMotha: i've hooked the vsync to the hsync line
08:41.59sorphinthe monitor went dual LED mode
08:42.04MonMothadid you leave vsync disconnected?
08:42.06sorphinaka, i pissed it off
08:42.09sorphinno
08:42.23MonMothaleave vsync disconnected for that, otherwise many monitors will still assume separate sync
08:42.31sorphini hooked the 'hsync' to the vsync line.. was making sure my syncs wren't crossed
08:42.41MonMothayeah, leave that disconnected
08:42.47MonMothahsync may be video (try green, in fact, for SOG)
08:42.57sorphinwell, this is an SGI monitor
08:42.58sorphinheh
08:43.12sorphintho i'm on the wrong connector for SOG
08:43.20joe_bleauBe kinda cool to get an image with just green and ground
08:43.21sorphini guess
08:43.24MonMothait's not fixed frequency, right?
08:43.28sorphinhell no
08:43.30MonMothajoe_bleau: that's how NTSC works
08:43.39MonMothayou have luminance with sync on it
08:43.53sorphinMonMotha: i'm doing 1280x1024 @ 75hz :P
08:44.08MonMotha(then for color you have the color subcarrier with saturation and hue IQ QAM modulated onto it up ~3.5MHz)
08:45.00MonMothayou're not going to burn in a scope in 5 minutes
08:45.06sorphinheh
08:45.09sorphinanyways
08:45.10sorphinso..
08:45.12joe_bleauLimited video experience...although I did once try your X/Y/Z trick on a dual beam 'scope.
08:45.16MonMothaeven if you ahve the intensity cranked
08:45.36MonMothajoe_bleau: it's kinda hard to do
08:45.38joe_bleauSet trig to norm and it'll idle with beam off.
08:45.39sorphinvid to vid, vid to vid, hsync to green, vsync to..
08:45.45MonMothavsync to hsync
08:45.48sorphinok
08:46.04sorphinif i blow up the monitor, you owe me $50 ;)
08:46.17MonMothasorphin: if it does bad things, turn it off :)
08:46.23MonMothathey're hard to blow up immediately
08:46.29joe_bleauDoes it have an OSD for the active input (sync rates, etc.)?
08:46.29sorphinactually
08:46.31sorphinwhat's nice
08:46.34sorphinyes
08:46.36sorphinwhat's nice
08:46.40sorphinif it senses something bad
08:46.46sorphinit goes into protect (that dual LED mode)
08:47.08sorphini guess i'll ahve to disconnect the damn KVM again
08:47.15sorphinonly way i'll know if i have sync or not
08:47.21sorphin(the kvm alawys outputs sync)
08:47.27MonMothajoe_bleau: it's not dangerous to underdrive a fixed freq monitor, right (just won't work)
08:47.29MonMotha?
08:47.44sorphinkvm w/ an OSD
08:48.07joe_bleauI wouldn't think so, just that the PLLs wouldn't lock.  But I've not used one in years.
08:48.22MonMothaI have an ancient Sun/Sony fixed frequency monitp
08:48.25MonMothamonitor
08:48.55joe_bleauHasn't everyone?  Mine was an intergraph, but wasn't a trinitron tube.
08:49.12MonMothanor is this
08:49.15MonMothastill looks damn nice
08:49.45sorphinthis is a trinitron
08:51.17sorphinman this is gonna be a lotta wires
08:51.18sorphinheh
08:51.39joe_bleau(JB is a just little jealous of sorphin's Tek 2465.  Hmm...make that more than a little.)
08:51.50sorphinhehe
08:51.58sorphinpaid good $ for it on ebay
08:51.59sorphinheh
08:52.37MonMothaI got my scope for free
08:52.50MonMothaI paid $35 for my frequency counter at Dayton Hamvention
08:52.52sorphinhow nice for you :P
08:52.58MonMothafor my signal generator (only 1Mhz :( ) for free
08:54.10sorphinok
08:54.15joe_bleauI've got a 5370A counter/TIA that I need to get fixed.
08:54.21sorphinMonitor:            Header:

08:54.58MonMothayup
08:55.00sorphinVsync               N/C
08:55.19sorphink
08:55.57MonMothajust tie them together
08:56.00joe_bleauJust a thought...do you have anything else running with an active VGA output?
08:56.01sorphinright
08:56.07sorphinbut this is an IDC connector
08:56.12sorphineh?
08:56.31joe_bleauMight 'scope it out and double check the waveforms as a comparison, so you'll have a clear picture of what the signals are supposed to look like.
08:56.47sorphinwell
08:56.55sorphinthere were only 4 total lines w/ signals
08:57.01sorphinthe rest are GND or +V
08:57.04MonMothajoe_bleau: I'd say he has a PC
08:57.38sorphinMonMotha: i have too many of those
08:58.11sorphinthis is that compactpci one
08:59.01MonMothasorphin: I was implying that you could scope the PC you're on's output for reference, as joe_bleau indicated
08:59.13sorphinheh
08:59.21sorphinnot easily
08:59.34MonMothayou don't have an HD15 to 5BNC adapter?
08:59.39MonMothaI thought everyone had one of those :)
08:59.39sorphinuh
08:59.41sorphinno
08:59.44joe_bleauOh, that would be ideal.
08:59.46sorphinplus there are near a wall :P
08:59.50sorphinin a 7' rack
09:00.05joe_bleauOh well, just a thought.
09:00.14MonMothaI need to figure out wtf my PS2's RGB output is doing
09:00.22MonMothathat and why my monitor is so dumb
09:00.37MonMothait comes up in SOG mode when I'm feeding it composite sync, and the SOG from the PS2 is broken
09:00.48MonMothamy composite sync is correct
09:00.50sorphinSuns use composite sync
09:00.59MonMothayes
09:01.07joe_bleauThey do?
09:01.10MonMothayup
09:01.11sorphinyep
09:01.18MonMothaSGIs tend to use SOG, but Sun uses composite
09:01.23sorphinhence why
09:01.36sorphinan HD15 <-> 13W3 for a sun
09:01.37joe_bleauHmm.  I made a cable for mine, but I think I brought both Hsync and Hsync across.
09:01.39sorphinwon't work on an SGI
09:01.43sorphinw/ out mods
09:01.51sorphinheh
09:01.56sorphinhsync and hsync? :)
09:01.56MonMothasorphin: well, the SGI pinout differs a bunch anyway
09:02.07sorphinMonMotha: uh
09:02.08joe_bleauReally?  I think I use the same cable for my Octane as well.
09:02.14sorphinyou just feed R G B
09:02.24joe_bleau(Lucky for me, my LCD supports SoG.)
09:02.25sorphinthe barrels
09:02.30sorphinthat's all the SGI needs
09:02.42sorphinbreak the pins off the other stuff
09:03.17joe_bleauHmm.  I've used it quite a bit with the SGI, but maybe I'm mis-remembering that it worked with a Sun.
09:04.08sorphinheh
09:04.19MonMothahttp://groups.google.com/group/comp.sys.sgi.admin/msg/ecd2ab873f59e03b?oe=utf-8&output=gplain
09:04.27MonMothaapplies more to SGI machines that do generate composite sync
09:04.43MonMothaI know my sun does give composite sync
09:04.48MonMothait's very old though (IPX)
09:05.11joe_bleauYeah, I've got a stack of IPX and SS2.
09:05.14sorphinalll mine do
09:07.01joe_bleauScabbed a DE15HD connector onto a TGX card rather than dealing with the 13W3.  But that was just to check that the card worked, not something I actually ran for any length of time.
09:08.27MonMothaI have an adapter to go both directions (so I can use my IPX on a PC monitor and a PC on my Sun monitor)
09:08.37MonMothaI think I paid $5 for both of them
09:09.48joe_bleauSounds like a good deal.  I don't think you can buy a single 13W3 connector from Digikey for $5.
09:10.01MonMothayou can't buy a single 13W3 connector from digikey period
09:10.06MonMothawell, at least not normally
09:10.25MonMothathey and Mouser occasionally get an order for <1 lot, but > min order, and they'll sell off the rest
09:11.31sorphinwell
09:11.34sorphinhere goes nothing
09:11.45sorphin(btw, i'd love to get teh 13w3 connector on the SGI monitor working :P )
09:12.35sorphindual LEDs again, lemme get the KVM outta the way
09:12.43sorphinbrb
09:13.37joe_bleauMonMotha: you're right...DK is showing a min order.  But Mouser has both sexes in stock right now.  Guess I saw it in the book, but never bother to check stock.
09:15.03sorphinok
09:15.12sorphineven with the monitor directly on the device
09:15.14MonMothajoe_bleau: Mouser must have had an order
09:15.18sorphini got dual LEDs
09:15.30sorphinaka bad sync
09:15.32MonMothasomeone will order like 500, they'll buy 1000, sell the 500 to that customer, then stock the remaining 500 until they run out
09:15.45MonMothatry removing the vsync line from the hsync connector
09:15.56sorphinok
09:18.12joe_bleauHey, are there any jumpers, DIP switches, or configuration settings required to enable the rear panel VGA output on this board?
09:19.10sorphinnottathing
09:19.14sorphinjoe_bleau: eh?
09:19.25sorphinno rear panel :P
09:19.38sorphinif i had the damn RIO board
09:19.40sorphini'd be fine
09:19.47joe_bleauSo the IDC connector is the only place to get the VGA output?
09:19.48sorphinthe case isn't big enough for that
09:20.00sorphinit's not even an idc connector
09:20.12sorphinit's a female header
09:20.13sorphinbut yeah
09:20.34joe_bleauOh, ok.  I was thinking that it maybe had two connectors.
09:20.36sorphinyou either get com2
09:20.37sorphinvga
09:20.52sorphinor ldvc or something .. it's LCD crap
09:21.09sorphinthese have com2, but the video's still present
09:21.39sorphinthe other one i won't have to care about doing this (i have 2).. cuz it'll do linux
09:21.47sorphinbut i need fbsd on this one to install JunOS

09:23.18sorphinMonMotha: jbevren used his monitor to 'pin it out'.. his has BNC connectors :P
09:23.35joe_bleauYou mentioned LVDS?  You're sure that's not what you're seeing on those pins, instead of standard VGA?
09:23.51sorphinwell, as i've said
09:23.58sorphinhe's used the video
09:24.13sorphinhence how he told me pin 1 was video, and b & c were sync

09:24.21sorphinyes
09:24.24joe_bleauHmm.
09:26.04MonMothahum, is there a way to reconfigure this thing maybe to act as an LCD driver, rather than VGA, and yours is configured differently?
09:26.18sorphinheh
09:26.51sorphinhell if i know
09:27.12joe_bleau(That 1V signal, and the inverted signal, sounded a little like LVDS.)

23:16.04T0mWchouimat|laptop: you running your LPC2138 in Thumb mode?
23:39.23MonMothaok, so the local pizza guys changed their price by $2 since they printed their ad TWO FUCKING DAYS AGO
23:39.54T0mWlucky you, you get it at the old price
23:40.07MonMothano, I wish
23:40.09MonMothait went UP
23:40.41MonMothait's still a decent deal for on-campus delivery, but I will not be buying frmo them again unless they start honoring their ads
23:40.48chouimat|laptopT0mW: no
23:41.41chouimat|laptopT0mW: seem that the hardware  guys screwed something as usual
23:43.15T0mWchouimat|laptop: maybe talk with you later, I've got to run
