Module Configuration
The operating parameters and functions of the CM1481 are programmed to the module (in its CONFIG mode) via
the Configuration Interface Connector from a PC running CML Configuration software.
The CM1481 is supplied, initially, configured to the DEFAULT settings as shown in the example menu below.
Over Air Re-Configuration will enable the changing of the following:
Tx Address
Transpond Mode
Rx Address
ANI Address
