Author Topic: DA20 input pinouts Josh Jones Redhat Posts: 1207 From: Plano, TX Registered: Apr 2000 posted 12-14-2003 06:11 PM                        are these inputs the same as the outputs as far as the pinouts are concerened?

Except for SW, which is only on the output d-sub. The input d-sub is normally only used in CP 200 situations, where the DA 20 breaks in between the processor and control units via JM 11 and 21. SW comes out of the processor unit.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

I did check and I do have the 611A. Thanks guys Josh  |  IP: Logged Josh Jones Redhat Posts: 1207 From: Plano, TX Registered: Apr 2000 posted 12-15-2003 11:36 AM                        OK, now we got a problem. I spent 2 hours last night trying to track down a surround seperation issue with the CP55. I hear the left surround feeding both speakers. i later found a stereo/mono jumper on the cat 441. now, I only have left surround, right suround is dead, and I have verified that the amp and speaker are good. What now?

I'd first consult a DA-20 manual and make sure all is as it should be on the backplane. There are a number of jumpers that are required as well as at least one trace to be cut. Right surround ends up on the far left terminal of the output strip.(TB3). You can simply plug the card in, but it basically does the same thing as a 241 then.  |  IP: Logged John Westlund Expert Film Handler Posts: 204 From: Burney, CA, USA Registered: Jun 2001 posted 12-15-2003 07:55 PM                     Somewhere I had the instructions for upgrading the CP-55 with the 441 card. If you need it Josh I can dig it out for you.  |  IP: Logged Rick Long Jr Expert Film Handler Posts: 211 From: Toronto, Canada Registered: Jul 2000 posted 12-15-2003 08:33 PM                     It's also in the manuals section here!  |  IP: Logged Josh Jones Redhat Posts: 1207 From: Plano, TX Registered: Apr 2000 posted 12-15-2003 09:42 PM                        I found out what was wrong. I had placed the Rs input lead on the wrong pin(Damn dolby for their confusing-as-hell lettering scheme). Now, about that 611A mod Josh  |  IP: Logged
