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.
Cross-over connection
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.
