The MESA 4P20 is a 11W POE power supply for PC/104 and PC/104-PLUS systems.  The 4P20 allows a remote PC/104 system to get power and high speed communication from a single CAT5 cable up to 100 Meters long.  The 4P20 supplies 5V at up to 2A, +12V at up to 200 mA and -12 at up to 100 mA via the bus connectors to the PC/104 stack.  The POE connection is done as a feed-through tap so the Ethernet connection can be routed to a local Ethernet endpoint.  Auxiliary power inputs are provided to allow external 18 to 60 VDC sources to power the 4P20 if POE is not available.  PC/104 power is electrically isolated from POE or auxiliary source power.
