Wire Replacement I/O (900 MHz): User Manual and Reference Guide
Appendix A: Troubleshooting Terminal Emulators
These are some common issues encountered while using terminal emulators
Nothing displays on the screen after placing the radio into Setup mode.
This usually indicates one of two things; either the wrong Com port is selected or a null modem
cable is being used.
Change the COM port, verify the cable, and attempt to connect again.
If the radio was previously configured, you could be using the wrong port to access the
Setup
menu.
Note
: For more information, see
.Try connecting to the other port.
Unreadable characters display on the screen after placing the radio into Setup mode.
This typically indicates a baud rate mismatch.
l
Unreadable characters before grounding the pin indicates Diagnostics is enabled and the
terminal emulator is connected to the Diagnostics pins.
l
Update the terminal emulator's baud rate to 19200 and reconnect to the radio.
The Setup menu displays on the screen, but nothing happens when keys on the keyboard are
pressed.
This usually indicates flow control is turned on in a three-wire connection (Rx, Tx, and Gnd).
Update the terminal emulator's flow control setting to None and reconnect to the radio.
A connection exists, the terminal emulator is receiving data, and some data is correct, but the
remaining data is in unrecognizable characters.
