IOP-241 Features, System Configuration | Omega Engineering guide

1. Introduction

The IOP-241 is a 24 channel digital input/output card for systems equipped with PCMCIA Type II and/or Type III expansion sockets.

1.1IOP-241 Features

PC Card Standard Specification 2.10 Compliant

24 TTL compatible digital I/O channels (8 channels can be used as interrupt sources)

äChannels individually programmable as either input or output

Active high sensitive, active low sensitive, low-to-high transistion or high-to-low transition interrupt modes (external interrupt available)

1.2System Configuration

The figure below illustrates a complete IOP-241 system. For users that do not wish to interface to the IOP-241 0.8mm I/O connector, an optional adapter cable (CP-1037) is available to convert this connector into an industry standard D-37 connector. For applications requiring discrete wiring hook-ups, an optional screw terminal block (UIO-37) is available to convert the D-37 connector into 37 single screw terminal blocks. These optional accessories are described in detail in Chapter 7.
