Displaying Antenna Circuit Condition
Background
The B125 board incorporates antenna detection circuitry, which senses the amount of current supplied to the
antenna's LNA. This circuitry indicates one of the two conditions:
•
not overloaded – the antenna draws normal current or is not connected to the board.
•
overload – the antenna draws current higher than expected. This condition occurs when the B125 board is
subjected to a load (i.e., antenna) larger than it was designed for. It could also be reported when a short circuit
occurs in the antenna, antenna cable, or the board.
When an overload condition is detected, the board maintains a constant, safe level of output current until the
overload condition is removed. For overcurrent values used to trigger the overload condition, see
Specifications
Typical Use
To verify that the antenna is connected securely and draws normal amount of current.
Procedure
Check the current delivered to the antenna.

Continuous monitoring of this command is a prudent maintenance practice to ensure your board and
antenna system function properly.
Restoring Default Settings
Background
Most of the parameters in the B125 have default values, which you may change as needed for your particular
application. You can always return the board to a known operating condition by restoring its default
configuration.
Typical Use
To return the board to a known operating condition.
To avert any configuration conflicts.
Procedure
This command causes the board to reset the settings stored in the non-volatile memory to the factory defaults
and then to reboot.
