SAMSC control of Christie Roadie 25k projector.

[meetmeatthemonkeybars]

Samsc will control a christie Roadie 25k projector via RS232.

For our application we have been trying to control the mecanical shutter within the projector.

Here is the .pdf from Christie explaining there RS232 commands.
RS232 Communication Data sheet for Christie Roadie 25k projector.

Here is a list of the equipment and cableing that we used to make this happen.

1 Roadie 25k projector
1 SAMSC
1 Keyspan highspeed USB to RS232 adapter.
1 Custom RS232 cable. (more on this in a min)

The commands that were entered into the SAMSC Serial interface were as follows.

For Shutter Open enter.
"(shu0)"

For Shutter Closed enter.
"(shu1)"

The settings for the RS232 communications within SAMSC were as follows.

baud=9600*
8bit
1s
None Parity

*the baud rate must be set in the projector to mach what you have set in SAMSC.

The serial cable was first made using a male and female D9 style connecter and wireing it in a straight thought configuration. Though this is the standard way to wire a RS232 cable we had to swap PINS 1 and 2 at one of the ends.

Male end (proj) Female end (dongle)
1----------------------2
2----------------------1
3----------------------3
4----------------------4
5----------------------5
6----------------------6
7----------------------7
8----------------------8
9----------------------9

With this wire configuration and setting we were able to control the shutter via RS232.

here are some screen shots of the SAMSC interface showing the various settings to get this to work.
