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.
1.1 IOP-241 Features
PC Card Standard Specification 2.10 Compliant
24 TTL compatible digital I/O channels (8 channels can be used as interrupt sources)
Channels 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)
1.2 System 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.
