EXM-GPIB

RadiSys EXM Bus Series Expansion Module Cards
Features

• Electrically Similar to the Standard PC ISA Bus
• 16-Bit Interface with EPC Modules

The RadiSys EXM expansion interface was developed in 1989 by RadiSys Corporation. It was conceived as a viable solution for local I/O expansion for a variety of system form factors such as VME (the most popular 32-bit industrial bus), VXI (the emerging standard for instrumentation) and EMC (a low cost, small, stand-alone form factor). The EXM expansion interface standardizes the local expansion of embedded PCs in a modular, reliable, space effective, and cost effective manner. It allows the addition of up to 8 expansion modules per embedded PC. Because the EXM expansion interface is electrically similar to the standard PC ISA bus, standard PC software can be used with all EXM modules.
