So I was able to finally get a connection between my Extron 200 and with the Extron software. I then can connect via hyperterminal, and see a bunch of characters when I turn the power on and off. The characters are not standard, so I am assuming I have the wrong emulation type. My question is can someone assist me in getting the switcher to recognize commands. I am not quite sure how to type these into hyperterminal so that the switcher recognizes them.

Can anyone help we diagnose the problem, as I am assuming this is something rather easy. The protocol docs are available from the website at the address below.

So I ended up downloading a COMPort Toolkit, and sent a message via this program, and it seems to work fine. So I must have some sort of hyperterminal program issues. No clue what they are.

Be sure to set up hyperterminal like this

9600, 8-bit, 1 stop bit, no parity

Also set flow control to none.

If you still see garbage then it is not an ASCII protocol and is sending unprintable characters. Not really a problem so long as you have the protocol.

If you get the settings right you should be able to use hyperterminal send esc > and turn it on and esc < to turn it off.

But that's about all you can do that's usefull in the simple protocol mode.

The Advanced mode is binary, so you won't be able to use Hyperterminal for that.

That is the answer I needed, as my version does not support the simple mode. So how hard is it going to be to write a PDL driver now that I know its not an ASCII type setup? The commands I type in for the Com Port Toolkit are very simple, and they work. I type in 32 80 B2 04, and hit send, and then it powers up the extron. Is its going to be this simple in PDL?

I would think so, looks it just ascii expressed as hex... PDL can do that I think.
Look at a simple binary PDL driver like the Kramer 2503 driver. It would be pretty similar to that one.
I'm not sure it will be that easy in PDL. There is some requirement to work at the bit level (dont know if you can do that in PDL) and there is also a checksum that needs to be calculated (although it looks like you can turn that requirement off, but I wouldn't)

You can do bit manipulation and checksums in PDL, so it probably will be ok. The Kramer example I indicated above uses bit ops.

Do I access this driver through the Macro workshop by starting a new session, and then click open for viewing? The Kramer driver looked much more complicated then the PDL driver for the Sky set-top box.

If I have to send commands that are formatted like this 33 80 B2 04, do I just make that a string?
