2.1.1 Ethernet Card Serial Port Wiring
The Ethernet card requires an RS-232 communications connection to the Rice Lake indicator. The indicator and
Ethernet card must be set to the same baud rate (Rice Lake indicators’ default serial baud rate is 9600.) To
change the Ethernet card baud rates, refer to the Lantronix User’s Guide.
1. To attach the 6-inch, unshielded cable directly
to the 920i , remove the serial connector from
the CPU board (port 1, 3, or 4).
2. Use the supplied 60-inch, unshielded cable to
run from J2 on the Ethernet board to the
connector of choice. Refer to the tables on the
following page for pin assignments.
3. Once cables are attached, plug the connector
into the header on the board. Table 2-1 shows
the Ethernet card serial port pin assignments.
