Serial Ports
Both serial ports provided are shipped in the RS-232C wiring configuration. To change either port to
an RS-422 configuration requires changing a jumper setting on the Serial Isolation Board located
inside the control on the back panel. Simply locate the appropriate jumper for the desired port at the
bottom of the board and move the jumper from the RS-232C position to the RS-422 position, which is
clearly marked on the board.
Warning! Configure the port for RS-422 Operation before connecting RS-422 compatible devises.
