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.
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
5-24 Series 90-30 PLC Installation and Hardware Manual – August 2002
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 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.
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).
