The RTI Remote can only utilize RS 232 via the IRF-6 using a CM-232 Serial Communication Module.

Below is example of RS232 HEX Code as used to discreetly turn a Runco 943 on or off

Power On\x02\x00\x00\x51\x0A\x00\x00\x01\x5C
Power Off\x02\x00\x00\x51\x0A\x00\x00\x00\x5B

There are also codes to select sources, adjust contrast, aspect ratio and so on.

Some devices use ASCII code which functions just like RS232 but for the most part uses phrases or words as part of the string as in the following Panasonic plasma commands.

Power On= \x02PON\x03
Power Off= \x02POF\x03

It would take quite awhile to explain the form and function of the RS232 world, but in a nut shell, it allows you to directly access the meat and potatoes of the particular device(s) brain you wish to control, this can be done much faster, more powerfully and with fewer errors than with a simple IR command.

RS 232 allows you to control other things like thermostats, fountains, start your car remotely, motorized blinds, make your computer perform some kind of task and so on.

(Page 32 in your manual) In the macro editor change the command type to RS232, where it says string type or paste in the command you wish to use making sure the baud rate and such, matches you devices settings. You also have to assign that code to just the output port the CM-232 is plugged into.

I would just like to point out that RS-232 is no longer the correct term for this standard and hasn't been for many years. Short for recommended standard-232C, RS232 was an unapproved serial interface standard whose original specification is never implemented fully and has gone through many changes. Once the standard was approved by the Electronic Industries Association (EIA) it ceased to be a recommended standard.

In 1987, the EIA released a new version of the standard and changed the name to EIA-232-D.

In 1991, the EIA teamed up with the Telecommunications Industry Association (TIA) and issued a new version of the standard called EIA/TIA-232-E.

Just some useless trivia that manufacturers still fail to recognize. Kind of like how people always called a 9600bps modem a 9600 baud modem, when it was, in fact, only 2400 baud.
