diagnostics cable.
2. Open up a Hyper Terminal session.
•
Use the following settings in connecting with hyper terminal
•
Connect to COMx (depending on which COM port your cable is connected to)
•
Set data rate to 19,200 , data bits - 8, Parity- none , Stop bits – 1 , Flow control – none .
3. Press the setup button next to the serial port on the radio. If you are using the diagnostics cable, press
Shift-U (capital U).
