1. Introduction
The OME-PIO-D96 provides 96 TTL digital I/O lines. The OME-PIO-D96
consists of four 24-bit bi-directional ports. Each 24-bit port supports three 8-bit
groups PA, PB & PC. Each 8-bit group can be configured to function as either inputs
or latched outputs. All groups are configured as inputs upon power-up or reset.
The OME-PIO-D96 has one D-Sub connector and three 50-pin flat cable
headers. Each header can connect to a 50-pin flat cable. The flat cable can be
connected to OME-ADP-37/PCI or OME-ADP-50/PCI adapter. The adapter can be
fixed on the chassis. It can be installed in 5V PCI bus and supports “Plug & Play”.
