To debug using the RPC and Hyperterminal:
Plug a 4-wire RJ-11 cable into the RPC jack on the back of the Domain 5000.
Plug the other end into an RJ-11 to DB-9 RS-232 adapter and into your PC
Select Start / Programs / Accessories / Communications / Hyper Terminal
Hyper Terminal will start running and will display a menu asking for the name of this connection. Type in any name (e.g., For debug) and click OK.
You will get a new menu asking how you would like to connect. Use the drop down to select COM1 (or whatever COM port your RS-232 serial port on your PC is using).
Click OK and you are connected to the Domain 5000.
Push Enter and you will get a response with the name of the Domain 5000.
type "root" (no password is needed)
For seeing if an IR code is received, type: cat /dev/hremoteir# where # is the number of the IR port you want to monitor.
