Serial Port 2
The connector pin array and signal names in serial port 2 appear below.
Insert the terminal resistor at the (+) pole.
If a terminal resistor is inserted, connect the RXR (+) to the RX (-) signal,
and the TXR (+) to the TX (-) signal.
If a terminal resistor is not inserted, connect the RX (+) to the RX (-) signal,
and the TX (+) to the TX (-) signal.
