24-Channel Digital I/O Module for PC/104 Bus

- Additional Information
The DIO96-104 is an 8-bit PC/104 peripheral providing 96 TTL/CMOS compatible digital Input/Output channels. The channels are organized as four 24-bit groups. Each group is controlled by a separate 82C55A peripheral interface chip which further segments its 24 channels into three 8-bit ports. This industry standard device offers very flexible configuration including software programmable port directions and strobed handshaking. All channels default to high impedance inputs during system reset. Pull-up and pulldown resistors are absent allowing the user's circuitry to individually dictate how each channel will be handled during reset and input modes. The four groups use a corresponding 26-position I/O header for all external wiring. The headers also include connections to the hosts +5V and GND for powering external circuitry.
The DIO96-104 occupies 16 consecutive locations within the host computers I/O map. The starting address is jumper selectable for any value between 0x000 through 0x3f0. The module conforms to the PC/104 (IEEE-996) standard and operates on a single +5V power supply.
