LED
By default, the LED on the Z50 modem module will indicate the following:
Green: Radio has received a packet
Red: Radio is transmitting a packet
Flashing Orange: GPS is trying to lock onto GPS or GLONASS satellite signals. (Flashing
will cease when Z50 has position lock from satellites)
Many commands modify the operation of the LED, including disabling it entirely. The ATL command can
disable the LED on the module, saving power consumption.
1.2.3
RF Antenna Connection
The RF Antenna Connection on the Z50 is an MMCX female. A typical mating connector, MMCX male, is
a RMX-9010-1B from RF Industries.
