GE IC697VRM015 Reflective Memory with
Use and RS-232/RS-485 adapter to connect systemstaht provide an RS-232 interface to the Software Load
(RS-232) serial port on the Ethernet Interface.
Catalog number IC690ACC900 is an RS-232/RS-485
converter; Miniconverter Kit IC690ACC901 also contains an RS-232/RS-485 converter. Refer to Appendix
B of the User’s Manual for more information.
10BaseT Network Port
The 8-pin RJ-45 phone jack 10BaseT network port is
used to connect a twisted-pair cable from a 10BaseT
hub or repeater directly to the Ethernet Interface
without an external transceiver. The pin assignments
for this connector are shown in Table 4.
Table 4. 10BaseT Network Port Pin Assignment
Pin Number Signal Description
1 TD+ Transmit Data+ (output)
2 TD– Transmit Data – (output)
3 RD+ Receive Data+ (input)
4 NC No Connection
5 NC No Connection
6 RD– Receive Data– (input)
7 NC No Connection
8 NC No Connection
AUI Port
The 15-pin AUI network port connects the transceiver
cable to the Ethernet Interface. The external 802.3
transceiver connects to the Ethernet network.
Connector pin assignments are shown in Table 5.
Caution
PLC power must be OFF when
connecting or disconnecting the
transceiver.
Note
Transceivers must be 802.3-compatible and
must have the SQE option Enabled.
Replaceable +12 VDC Fuse
A replaceable fuse is available on the +12 VDC power
that is supplied by this module to the AUI port to
power external transceivers.

10Base2 Network Port
The BNC 10Base2 network port is used to connect a
10Base2 (ThinWire) network directly to the Ethernet
Interface without an external transceiver. The 10Base2
network cables are attached to the Ethernet Interface
with a T or F BNC connector.
Onboard 10Base2 Port Transceiver
Power Disable Jumper
This jumper must be in place to ensure proper net work operation when using an external transceiver
connected to the AUI port that is externally powered.
Default Stations Address Label
The Default Station (MAC) Address label lists the station
address to be used by this module, unless a locally
assigned address is set by the user via the Station
Manager. It is found on the inside edge of the
protruding flange of the module faceplate. The Default
Station Address label is visible when the Ethernet
Interface module is inserted in the PLC rack.
