Ethernet, COM2, and COM3 Connections
The Ethernet/TCP IP and dual COM port option board (Figure 2-27) is positioned in
the center option slot on the Main board. This port provides a 10 Base-T
connection (10 Mb) connection for Ethernet and two serial ports labeled COM2
and COM3. The Ethernet connection is made via a standard RJ45 connector on the
option board. The connector is shown in Figure 2-27.

COM2 provides only RS-232 and should be connected as shown in Figure 2-28.
COM3 provides RS-232, RS-422 or RS-485 connections, which is identical to
COM1 on the Main board except the +5 VDC supply on the last terminal is not
provided. Refer to the COM1 connection section described previously for
instructions for wiring to this port. Review Figure 2-21 and Figure 2-22 for
additional details.
