Octal LAN 10/100Base TX Module, E100-8
12.1 Module Description
This module contains eight Ethernet interfaces that support both 10Base-T and 100Base-TX according to the IEEE 802.3 specification. The interface supports both the half-duplex and the full-duplex modes. The interfaces are connected to an integrated Ethernet switch. The physical interface uses a RJ-45connector. Every interface also has a LED that signal the status of the link. The module supports IP interface only.
12.1.1 Power Consumption
5,5 W.
12.2 External Interface
The interface is a 10Base-T and 100Base-TX Ethernet interface according to the IEEE 802.3 specification. Cabletype must be CAT5-STP
12.2.1 Pinout
The connectors are RJ-45 connectors, with the following pin-out:
