IND560 PDX Installation Manual
COM3, USB, Ethernet Connections
The Ethernet/USB/COM3 option board (Figure 2-37) can be positioned in the center
option slot on the Main board. This option board provides a USB Master,10 Base-T
connection (10 Mb) connection for Ethernet and a single serial port labeled COM3.
The Ethernet connection is made via a standard RJ45 connector on the option
board. The connector is shown in Figure 2-39.
Figure 2-39: Ethernet/USB/COM3 Option Board
The COM3 has similar function as the COM3 serial port of the
Ethernet/COM2/COM3 option board shown in Figure 2-37. However, the COM3 on
the Ethernet/USB/COM3 option does not support RS-422. It only provides RS-232
and RS-485 connections and can be wired the same as the standard COM1 serial
port. Refer to the COM1 connection section described previously for instructions for
wiring to the COM3 port. See Figure 2-30 and Figure 2-31 for details.
Important: When installing either the Ethernet/COM2/COM3 or the
Ethernet/USB/COM3 option, adhere the "Ethernet" label from the kit to the rear panel
of the panel-mount unit near the Ethernet connector. On the harsh enclosure,
adhere the "Ethernet" label to the Main board cover near the Ethernet connector
(Figure 2-41). This will help to differentiate the Ethernet TCP-IP port from the
optional EtherNet/IP PLC port in the situation where they are both installed.
