There is not really a way to convert a serial code (RS232) to an IR Code. They are two different formats, two different protocols. It's like trying to convert from ancient egyptian to english without the rosetta stone. There are devices that take an IR command and convert it to RS232 (serial) like the RCV-5000, but that piece was designed specifically for a particular product.(centralite) I don't know if there devices that take rs232 and convert it to IR.

iConvert and global cache have their own way of displaying IR commands. Commmonly, particularly on this website and others, when you see hex codes or read someone referring to hex codes from a remote, they are talking about codes that are in the pronto hex code format. It is the most ubiquitous and useful. Global cache stores the hex codes in their devices in a different format other than pronto hex. That is what Iconvert does. It takes IR hex codes and converts them back and forth between pronto hex and GC hex. (Thanks global cache and Savant for not using pronto format like the rest of the automation world).

What iconvert WON'T do is convert serial to IR. You have serial commands, in hex format, which is completely different than IR in hex format. I hope this isn't diving too deep. I don't know your baseline. What you need is a spread sheet from the manufacturer with IR hex codes. I have to look up the manual, does this product take IR codes? Some don't!

I would start here:

I realize this is a different model, but right now, what else do you have?

The GC-100 has two serial outputs. Why aren't you using them?
