Connectors and Cabling

Overview The following information describes the 10/100 BASE-T and 100 BASE-FX

connectors.

10/100 BASE-T

Twisted Pair

Connector

The NOE 771 xx, NWM 100 00, and CPU 651 x0 modules’ 10/100 BASE-T

connector (shown below) is a standard RJ-45 twisted pair socket:

Schneider Electric recommends that you use Category 5 STP cabling, which is rated

to 100 Mbps, with an RJ-45 connector.

The eight pins are arranged vertically and numbered in order from the bottom to the

top. The RJ-45 pinout used by this module is:

z Receive Data (+)3

z Receive Data (-)6

z Transmit Data (+)1

z Transmit Data (-)2

100 BASE-FX The 100 BASE-FX connector for the NOE 771 xx, NWM 100 00, and CPU 651 60

modules is an MT-RJ socket or a mating fiber optic cable connector.

For the NOE 771 xx and NWM 100 00, you may need an MT-RJ to SC (duplex)

multimode fiber optic cable assembly 62.5/125mm. Schneider Electric recommends

cable number 490NOC00005 to connect to fiber hubs/switches.

Pins

Note: The NOE 771 xx and NWM 100 00 are one-channel devices that can

communicate over either 10/100 BASE-T or 100 BASE-FX Ethernet networks at

any given time, but not over both at the same time
