Micro/Sys MPC196 - High density digital I/O Simple Type: Expansion Module
The MPC196 is a plug-on PC/104 board that adds high density digital I/O to PC/104 systems. Four 82C55s provide bi-directional interfaces to and from A/D, D/A, and general system I/O. Each of the 96 lines can be individually controlled and are bi-directional in groups of eight. System reliability for this additional I/O is enhanced with grounds between each 82C55 signal. Consistent system start-up status is controlled with pull-down/pull-up resistors on all I/O lines. The robustness of the MPC196 protects against power sequencing problems in PC/104 systems. This is accomplished with on-board current-limiting resistors that prevent overload currents.
