The Eurotech COM-1267 is a versatile high reliability multiport 10/100Mbps Ethernet Switch expanding one port to up to four devices that are networked together using 10BaseT Ethernet connections, through onboard shielded RJ-45 connectors or alternatively using Molex connectors. This module can be used as a standalone switch or it can be integrated into a PC/104 or PC/104Plus system. This switch is the ideal choice to used together with any Eurotech CPU module.

The COM-1267 can optionally feature a special crossover connection between any two of its Ethernet ports. That can be implemented in three different ways: automatically when the module is in power off, through software, or when a watchdog signal is received from an Eurotech CPU module.
