Subtract the function code from 255 and you have the reversal function code.

can you email me the complete doc. I have a friend that's pretty good at figuring out rs232 protocols. I have 2 HD-XA1's that need to be controlled via rs232

mark,

confirmed, HD-XA1 responds to serial commands per your doc. provided.
Must use Null Modem cable, since pins 2 & 3 are reversed (vs the Global Cache GC100-12).

Credit for the above goes to David Snipp, CEO of Stardraw Control, www.stardraw.com

btw, the HD-XA1's rs232 port is not bi-directional (at least, not yet), no feedback!

I am not having luck getting the RS-232 to work with the HD-XA1. Do I need to input the Hex serial code in a different way?

I'm using a T3, w/RP-6 and CM-232 w/Null Modem Adapter and Female/Female Coupler.

The command shown below is for PLAY.

Here is the answer to my question:

I didn't select "Hex" and I needed a 1ms delay. I tested many different delays; I found that 1ms worked 20 of 20 times.

I have attached a screen shot of what you need.
