Keyswitch
This is a standard CPU keyswitch, discussed earlier in this chapter.
Front Panel Connectors
The full functionality of these ports is detailed in GFK-1541,
TCP/IP Ethernet Communications for
the Series 90 PLC User’s Manual.
■ Port 1, RS-232 - This connector is used for two purposes: (1) To connect a terminal or
terminal emulator to access the Station Manager software on the Ethernet Interface. (2) To
connect to a Personal Computer that will be used to update the Ethernet Interface firmware
(the CPU firmware is updated separately through the connector on the power supply). This
RJ-11 connector has the same pinout as Port 1 of the CPUs 351, 352, and 353, shown in Table
5-5. The IC693CBL316 cable can be used to access this port. See Chapter 10 for a data sheet
on this cable.
■ AAUI port - This 14-pin AAUI port connects via a user-supplied IEEE 802.3 transceiver
cable to an external Ethernet-compatible transceiver such as the GE Fanuc catalog number
IC649AEA102 (for 10Base T) or IC649AEA103 (for 10Base 2). See Appendix J for details on
these transceivers.
■ 10Base T port - This 8-pin, RJ-45 port provides a direct connection to a 10Base T (twisted
pair) Ethernet network without the need for an external transceiver.
Shield Ground Connection Tab
This tab is used to make the module’s shield ground connection. A wire with the applicable
terminal ends is supplied with the module for this purpose. Please see the section “CPU363 and
364 Shield Grounding” in Chapter 2 (“Installation”) for details.
Firmware Upgrade
■ The CPU firmware, which is stored in Flash memory, is loaded through the serial port
connector on the PLC Power Supply using a personal computer that has been equipped with
the loader and CPU firmware software.
■ The Ethernet Interface firmware, stored in Flash memory, is loaded through the module’s front
panel Port 1 connector using a personal computer that has been equipped with the loader and
Ethernet firmware software. Cable IC693CBL316 is required (see Chapter 10 for details on
this cable).
