MReX Transceiver User Manual v1.92 Firmware
*LOW_BATT
*LOW_BATT specifies the voltage (multiplied by 10) that the low battery sounder will be heard at.
This option is only used when *RX_ENABLE=0. When *LOW_BATT is set to 0, low battery
checking is not performed. Max value is 33 (3.3 volts)
Typical usage:
*LOW_BATT=26<CR>
*LAB
Set the unit in transmit mode, it can be configured to transmit carrier only or modulated. This fea-
ture together with the *RSSI command are useful when antenna alignment is necessary.
*LAB syntax:
*LAB=x,y<CR>
Where:
x is used to:
1 – Enable Carrier only,
2 – Enable Carrier with random modulation,
0 – Disable Carrier
y is the time in seconds which the MReX will be transmitting for.
Example carrier only for 60 seconds:
*LAB=1<CR>
Example carrier only for 20 seconds:
*LAB=1,20<CR>
