Omega Vehicle Security OME-PIO-D56 - Manual (Page 5)

1. Introduction
The OME-PIO-D56/OME-OME-PIO-D24 provides 56/24 TTL digital I/O lines.
The OME-PIO-D56/OME-OME-PIO-D24 consists of one 24-bit bi-directional port,
one 16-bit input port and one 16-bit output port (only for OME-PIO-D56). The 24-bit
port supports three 8-bit groups PA, PB & PC. Each 8-bit group can be individually
configured to function as either an input or an output. All groups using 24-bit bi-
directional ports are configured as inputs upon power-up or reset.
Use the OME-DB-24PD to connect the input port for either isolation purposes,
or to interface to the output port for relay control. The OME-PIO-D56/OME-PIO-D24
has one D-sub connector and two 20-pin flat-cable connectors (only for OME-PIO-
D56). The flat cable can be connected to an OME-ADP-20/PCI adapter. The adapter
can be fixed on the chassis. It can be installed in a 5V PCI bus and supports “Plug &
Play”.
