IND560 Installation Manual
Ethernet, USB, COM3 Connections
The Ethernet/USB/COM3 option board (Figure 2-27) 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 2-29.
The COM3 has similar function as the COM3 serial port of the
Ethernet/COM2/COM3 option board shown in Figure 2-27. 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 2-21 and Figure 2-22 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 (Figure 2-30). On the harsh
enclosure, adhere the Ethernet label to the Main board cover near the Ethernet
connector (Figure 2-31).
