Preliminary - The 75D2 is a 3U cPCI multifunction serial communications and digital I/O board. The “mother board” can be populated with a function specific module, such as RS232/422/485, Discrete I/O, TTL I/O and a 6 port unmanaged Ethernet switch. This card can be controlled by either via Ethernet (10/100/1000Base-T) or by the cPCI bus. A Software Support Kit (SSK) is supplied which provides help documentation and sample code.
