28 Installing the Radio
The RJ45 control head on the TM8252 telemetry radio has one RJ45
socket installed and an cavity where another RJ45 can be installed. The
control head also has a power on/off LED.
Important
When a connector is not in use, the RJ45 bung for the
connector must be installed. This ensures that the control
head is sealed against water, dust and other
environmental hazards.
