The serial port pin assignment table shows the pin assignments for Ports 1, 3, and 4. Port 2 provides DIN-8 and
DB-9 connectors for remote keyboard attachment of PS/2-type personal computer keyboards (see below). The
DB-9 connector pin assignments for Port 2 are shown in the DB-9 Connector table below.
Serial ports are configured using the SERIAL menu.
An optional dual-channel serial communications expansion card, PN 67604, is also available. Each serial
expansion card provides two additional serial ports, including one port that supports RS-485 communications.
Both ports on the expansion card can support RS-232 or 20mA connections.
