Title: 1084 Cable Pinout Question for custom cable
Post by: trip6 on August 25, 2008, 04:07:52 PM
I have a 1084s nmonitor and an Amigen Genlock... I am trying to get a custom cable built to connect the two, both devices have 9-pin d-sub female connectors so the cable would be 9-pin male d-sub to 9-pin male d-sub.

Here are the pinout information that I found:

9-pin Video connector (used by A2002 and A1084 monitors, AmiGen genlock):
  Pin01 = Sync ground        
  Pin02 = RGB ground          
  Pin03 = Red                
  Pin04 = Green              
  Pin05 = Blue
  Pin06 = no connection
  Pin07 = combined Sync
  Pin08 = no connection
  Pin09 = no connection
 
My question is where do the ground wires for Red, Green and Blue get wired to? Sync Ground and RGB Ground? What gets wired to combined sync, the hot side of Red, Green and Blue?

I really need to know this to make a cable, does anybody have any answers? I really appreciate any help...

Thanks.
Kevin

In that list:

Pin07 combined Sync = combined Horizontal/Vertical scan control signals, the ground for that wire is Pin01. Those two wires make a circuit. Do NOT connect any of the RGB to Sync - it won't help at all...

Pin02 is the one and only ground wire for the three colour signals. So each of R, G, and B form a circuit with the common ground.

Ok I understand the RGB share a common ground with Pin 2.

But... So Pin 1 gets wired to pin 7 as in with a jumper wire I guess or just the ground side from pin 1 gets wired to the ground side  for pin 7? each wire has a hot \ ground side, yes? Or am I mistaken, can you draw a schematic? just so that I fully understand... Don't want to short something... Thanks again.

Thanks again. Specifically I am referring to the notation that you made about this:

Pin07 combined Sync = combined Horizontal/Vertical scan control signals, the ground for that wire is Pin01. Those two wires make a circuit. Do NOT connect any of the RGB to Sync - it won't help at all...

Can you please clarify, how is this connection made? A jumper wire?

Thanks for all your help and efforts.

There is a monitor on one end of the cable...

Once you get the pinout figured, these guys can make  custom cables: Redmond Cable (http://www.redmondcable.com/)
