these pins can be used to connect a power LED1
these pins can be used to connect LED2 and LED3 which are driven by the
output pins of the core module
these pins can be used as inputs for switch SW1 and SW2 and are internally
connected to pins 17 and 18 of the HITAG core module
receiver input; this antenna signal input has to be connected to the input line of
the antenna
transmitter output; this antenna signal output has to be connected to the
output line of the antenna
antenna ground; the ground line of the antenna has to be connected to this pin
