Author Topic: Christie RS232 Communication Markus Lemm Expert Film Handler Posts: 113 From: Ottawa, Ontario, Canada Registered: Nov 2005 posted 08-28-2012 02:43 PM                        First the equipment: Dolby DSS/DSP100 cinema processor Christie 2000ZX Projector I managed to run a straight through RS232 cable from the DSP100 to the RS232 B connector on the Christie. I also managed to get basic Shutter open and Shutter Close commands to work using the Christie Serial API. [(SHU 0) and (SHU 1) commands] I'm wondering if I can access the GPIO on the Christie from the Dolby using serial commands? It seems like you can access most of the internal workings of the machine but I can't find any GPIO stuff.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

From what I can tell, the Christie D-cinema projectors use the same command set as most other Christie video projectors. See this manual for more examples, although I am willing to be that the scaling and image processing commands do not work on the D-cinema units.. Let us know if it works. Note that the Christie douser has a delay of about one second after the command is sent to it before it opens or closes, so be sure to account for that in the programming. I find this highly irritating, especially for environments where one needs to be able to make seamless changeovers from film to video and back in one program.  |  IP: Logged Markus Lemm Expert Film Handler Posts: 113 From: Ottawa, Ontario, Canada Registered: Nov 2005 posted 08-28-2012 03:53 PM                        Wow! Great manual. Thanks. Unfortunately I can't try any commands until next week. I will post again once I have some results, but this looks like what I need. Thanks again  |  IP: Logged Markus Lemm Expert Film Handler Posts: 113 From: Ottawa, Ontario, Canada Registered: Nov 2005 posted 09-18-2012 01:08 PM                        No luck. Just returns an error message when I try (GIO?). I tried (HLP?) to get a list of commands and nothing related to GPIO came up. At least the dowser, masking and lamp stuff works.  |  IP: Logged
