Introducing the CIO-DIO192

Overview: CIO-DIO192 features

The CIO-DIO192 has 192 digital I/O connections, and eight 82C55 parallel-interface chips.

Each 82C55 chip controls 24 CMOS/TTL-compatible digital I/O pins. Each 24-bit group is divided into three

eight-bit ports, or two 8-bit ports and two 4-bit ports. Each port is programmable for input or output.

All I/O bits are set to input mode (high impedance) on power up and reset. Locations are available for installing

pull-up or pull-down resistors.

All signals pass through a 50-pin connector.
