Author Topic: Dolby CP55 - Cat321 - SRA5 question Serge Bosschaerts Film Handler Posts: 70 From: Schoten, Belgium Registered: Jan 2000 posted 12-21-2004 04:23 AM                        I'm getting a Dolby CP55 soon and this unit will be replacing my CP50 but the CP55 doesn't have a cat.321 automation card. I have a SRA5 hooked up to the CP50 and off course I want to use it also with the CP55, in the manual of the SRA5 Dolby says you need a cat.321 to hook up the SRA5, can it be done without and can I connect my Cinemation IV on the J5 automation port on the backplane of the CP55 ? If I need a cat.321 is this a easy card to find ?

You can get away without a 321, two ways.. 1. Dont automate it - leave it active all the time - few films are in A type but you MUST turn the SRA5 off when running A type or.. 2. The CP55 formats are internally switched using a three bit word. By chance, one of these lines can be used as the other times it is active it doesnt affect the analogue. Try this.. no 321 - connect id7 to pin 7 of automation d connector (female on chassis, needs flying male) Good luck Cheers  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 12-21-2004 09:04 AM                     If I may interject; Peter is quite right about that, but I would add that you ought install it to the CP55, by the method described in the DA20 manual, not the original method as described in the SRA5 manual. It works much better and there's no calibrating to be done.  |  IP: Logged Peter Hall Master Film Handler Posts: 314 From: London, UK Registered: Dec 2000 posted 12-21-2004 11:58 PM                        and you dont have to go back when someone tweaks what they think is the non sync controls.. Must be cold in Scotland - have a good Xmas Pete..  |  IP: Logged Serge Bosschaerts Film Handler Posts: 70 From: Schoten, Belgium Registered: Jan 2000 posted 12-22-2004 09:07 AM                        Thanks guys, I was also wondering if I would follow the method in the SRA5 manual but after reading the method in de DA20 manual, the latter seems the best way to hook up the SRA5.
