RS-422/485 serial port in RS-422 mode

Four RS-422 separate data pairs are provided for transmit (TX) and receive (RX).

Additionally, there is a 120 Ohm terminating resistor provided for each data pair for

applications that require an EOL termination. The termination is optional and is accessible by

connecting the terminating pin for each data transport pair.

To enable termination for the transmit pair, connect the terminating resistor pin (TX

Terminator) to the positive data transmit (TX+) pin.

To enable termination for the receive pair, connect the terminating resistor pin (RX

Terminator) to the positive data receive (RX+) pin.

Power (+12VDC) is provided on pin 4 and is referenced to ground, pin 5. The power pin is

protected by a self-resetting fuse and is limited to 0.5A, max.

Note: Transmit (TX) and Receive (RX) are from the point of view of the NioNode. Connect

them to the opposite port of the remote unit.
