Diamond-MM-48-AT (DMM-48-AT) is a PC/104 expansion board offering embedded systems 
designers a full feature set of analog and digital I/O capabilities. It is designed to be used in 
any PC-compatible embedded computer with a PC/104 (ISA-bus) expansion connector.  

DMM-48-AT offers reduced embedded system size and weight, as well as lower cost, by 
providing more functionality on one board than other data acquisition boards.
