Typically you can use a video camera pointed at an IR emitter to see the flash. Most video cameras can pick up IR flashes and they are visible when you look through the viewfinder.
If you have not done so, you really want to play with Simpl Debugger in Toolbox. This is the one tool which lets you apply a signal directly to a connection and see if it works or doesn't work.
You will also want to go to the Yahoo forums for Crestron and get in that group. The Yahoo forums Crestron group is one of the best around with many programmers who can help you out.
If you PM me with your email address I can send you a nice power on/off module which works well with various displays and A/V receivers when using 1-way communication. It will power on/off the display when you choose an input for it, and switch to that input after it has powered on in 'xx' seconds. If you power it off before it is fully powered on, it will just power off immediately. It tracks power, and input states, which makes it nice for televisions, projectors, and A/V receivers.
For the Epson 8350, here are the commands to put into a serial I/O:
Power On: PWR ON\x0D
Power Off: PWR OFF\x0D
Component 1 (YCbCr): SOURCE 14\x0D
Component 1 (YPbPr): SOURCE 15\x0D
Input 2 PC: SOURCE 21\x0D
Input HDMI 1: SOURCE 30\x0D
Input HDMI 2: SOURCE A0\x0D
Input Composite: SOURCE 41\x0D
Input S-Video: SOURCE 42\x0D
I don't believe that I am even switching inputs on the 8350 I programmed, I just leave it on HDMI 1 and that's it. Power it on, power it off, that's all.
If you just took the 101 class, then there's a lot to learn still, but you do want to get a basic system going with IR commands and basic serial controls. Learn how to make some cables and hook things up properly. Most people get into programming after years of installation work so they know the installation is good. It's a bit more difficult if you aren't already comfortable with installation work and don't have someone local to help you out. Good luck!
