1. Connect the serial communication cable between the RS232 outport of the receiver
and the serial communication port (COM1 or COM2) of the PC.
2. Make sure that the PC is on and the receiver is in Power on mode.
3. Run “Hyper Terminal” program of the PC from Start / Programs / Accessories /
Communications / Hyper Terminal menu.
4. For a new connection, run Hypertrm.exe file.
5. Give a name and choose an icon for the connection. (You do not need to make a
new connection every time. You can use this name for the future connections.)
6. Choose communication port in the new coming window (COM1 or COM2)
whichever you have used in Step 1.
7. Port settings should be as follows:
Bits per second : 115200
