RS-232 control of projector via ION

I'm trying to control projector inputs and shutter states via RS-232 using the ION console but having difficulties.  The goal is to change inputs and shutters via cues, but for testing purposes I'm using macros.  The projector is a Panasonic DZ6700U.  It has RS-232 control options enabled.  

I have the manual for the projector which indicates the syntax and codes to use. For example STXADZZ;IIS:VIDETX should change the input to video.  Of course nothing happens. Is there a special character for STX and ETX?  I've also tried sending the hex codes as well.  The projector is set to respond to all commands and the ID I'm using (ADZZ) is an ID ALL.  The ion has String TX/RX enabled to group ID's 1 thr 32.

 

Where would/is it possible to see the response from the projector?  I've monitored the diagnostic screen and see the send codes, but no response.

What is the baud rate and parity in/out of the ION?

When using macro's to "send string" does it send the string as is or in hexadecimal format?

I believe somewhere that some of the serial ports aren't enabled on the Ion depending on what version you have.  Is there truth to this?  How do I find out if my version works?

 

Of course this would be easier if the ION suppored PJLink.  Maybe some day.  :)

Thanks!

    There are other ways to get RS232 out of an Ion (adding an I/O gateway or using a UDP to RS232 converter), but that's not the only thing preventing this from working.  I looked at the manual for your projector and it does look like it uses the ASCII characters for STX and ETX.  These are 0x02 and 0x03 respectively.  Unfortunately, the Ion doesn't currently have a way to enter those hex characters in a string.  For your example string it would actually be sending the individual letters S, T, & X instead of the correct ASCII STX character.

    This is probably a long shot, but what does your space use for architectural control?  If it's a Unison Paradigm system, then that would be capable of sending the command in the format required by the projector.  It would also be possible to set it up so that Ion can send a string to Paradigm over the network as part of a cue and have Paradigm send the correct command to the projector.  These configuration changes to Paradigm would require help from a technician, so you would need to talk to your local dealer about doing that.

    Another option is to make use of the contact closure input (REMOTE 2 IN terminal) on the projector, and build a box with some push-buttons that can be located near the Ion or SM desk.  It's not as fancy, but it would give you the control you need.

    From the second option Mark described you could even buy a DMX-Relay Switch board and then you would be able to control the buttons via DMX.
