DIAMOND-MM-48-AT
Autocalibrating Analog I/O PC/104 Module
1. DESCRIPTION
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.
