Single Board Computer COM-1267

The COM-1267 is a versatile 10/100Mbps five-port Ethernet switch that can function in 10baseT or 100baseTX modes and allow connections made through onboard RJ-45 connectors.

The COM-1267 can be used as a standalone module or integrated within a PC/104 or PC/104-Plus system together with a Eurotech CPU module.

The COM-1267 can optionally feature a cross-over connection between Ethernet ports 2 and 3 that can be activated via software, automatically activated when the board is powered off, or activated when a Watchdog signal is received from the host Eurotech CPU module.

Typical applications for the COM-1267 include remote data acquisition, machine monitoring, process control, environmental control, and communications gateways for factory automation, aerospace, telecom and transportation.
