You can also use Dilard for serial control of the D-ILAs, if you don't want to roll your own solution from the docs. The automation features of the software are free, and you can do just about anything you could possibly want to do through RS232. www.dilard.com
Everything the projector can do is available via RS232...even stuff that you're not supposed to do. However, I don't know if there are discrete IR codes to change to a specific video source without cycling around.
One idea I once had (but never did) was to program one of these Ocelots to accept IR and turn it into RS232.
This is a clever (but sophisticated) device. You teach it an RS232 code, then teach it an IR code and match them up. Once you have it programmed, you stuff it into the RS232 port of the projector.
From that point forward, you send IR, the the projector receives RS232. In other words, FULL control of the projector (including all discretes) from a learning remote.
No computer is required in this set-up, but the reason I didn't do it is that it appears to be quite an experience to program the Ocelot (which does require a computer).
Just thought I'd let you know about an alternative.
Yes, those codes are available. The complete list is in the document(s) that Tom Stites referenced.
I agree that the Ocelot would be a silly addition if you have a Panja. You can do just what you need from the RS232 reference doc.
The language is a little...odd...but it works. You can probably ignore the return codes from the projector. As long as you are sending valid data, the projector will not generally return an error code.
