I am programming my first DBX 1260 and it requires rs232 for the commands. The problem for me is that they do not give the commands, they have a string calculator that is suppose to give me the hex string. The instructions on doing this is VERY vague!!! Can someone just walk me thru on programming a command so that I can replicate it on others. My equipment list:

RTI XP8
RTI RK3-V
DBX 1260

I am just trying to get volume up, down, mute and sources. 1 and 5

Thanks for the help.
