I/O connections
The AM TRX board is equipped
with two I/O’s which can be used for connecting a
pushbutton (Forced Alarm option) or as output for other external devices (e.g. camera).
To avoid interference, caused by the wires which will be connected to any of the I/O’s, it
is very important to only connect the wires to the I/O connector contacts.

Do not connect any of the wires directly to a GND contact on the TRX board or on
the power supply! Use the “GND” connector to connect to the ground.

The I/Os have a current limit of 70mA. Do not connect devices to the I/Os that draw more
than 70mA, else the I/O drivers will get damaged!
