Chapter 1
Introducing the PCI-DIO96 board
Overview: PCI-DIO96 features
This manual provides installation and programming information for the PCI-DIO96 digital I/O board.
The PCI-DIO96 is a 96-bit line digital I/O board. The board provides the 96 bits in 24-bit groups based on the
82C55 specification. Each 24-bit group is divided into three eight-bit ports.
The ports are labeled on the board as PORT #A, PORT #B, and PORT #C, where # is from 1 to 4. PORT #C
can be further split into two four-bit nibbles — PORT #C-HI and PORT #C -LO.
Each of these ports may be individually programmed as input or output.
Software features
For information on the features of InstaCal and the other software included with your PCI-DIO96, refer to the
Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at

PCI-DIO96 User's Guide Functional Details
Signal level control
All the digital inputs on the PCI-DIO96 are 8255 CMOS TTL. The PCI-DIO96 output signals are 8255 CMOS.
Note
The 82C55 digital I/O chip initializes all ports as inputs on power- up and reset. A TTL input is a high
impedance input. If you connect another TTL input device to the 82C55 it could be turned ON or OFF every
time the 82C55 is reset. Remember, the 82C55 is reset to the INPUT mode.
On power up and reset, all I/O bits are set to input mode. If you are using the board to control items that must
be OFF on reset, install pull-down resistors. The PCI-DIO96 has open locations where you can install Single
Inline Packages (SIP) resistor networks in either pull-up or pull-down configurations (refer to Fi ).gure 4
Figure 4. Open locations for SIP packs
You can install pull-up and pull-down resistor SIP packs at PORT #A, PORT #B, and PORT #C. These ports
are adjacent to the I/O connector. When installed, the SIP establishes either a high or low logic level at each of
the eight I/O lines on the port.
16

PCI-DIO96 User's Guide Functional Details
To safeguard against unwanted signal levels, the devices being controlled by PCI-DIO96 series boards should
be tied low or high as required by a 2.2K Ωresistor. In a 2.2K eight-resistor SIP pack, one side of all of the
resistors is connected to a single common point and brought out to a pin. The common line, usually marked
with a dot or line, is at one end of the SIP. The remaining resistor ends are brought out to the other eight pins
(refer to Figure 5).

10 holes in a line. The end labeled HI connects to +5V. The end marked LO connects to GND. The eight holes
in the middle (n0 –n7) connect to the eight lines of the Port, A, B or C.

Inline Packages (MCC part number SP-K2.29C). Use a different value only if necessary.

PCI-DIO96 User's Guide Functional Details
CIO-ERB24 and SSR-RACK24 daisy chain configuration
Many relay and solid-state relay (SSR) racks provide only 24-bits of digital I/O. You can configure the
CIO-ERB24 relay output board and SSR-RACK24 I/O module rack in a daisy chain configuration to use all of
the digital I/O bits provided by the PCI-DIO96 board. An example of the daisy chain configuration scheme is
shown below.
The PCI-DIO96 board provides digital I/O in a group of 96 bits. Each of the C100FF-xcable's 50-pin
connectors provides 48-bits. To use all of the board's 96 digital I/O bits to control relays and/or SSRs, configure
the daisy chain as shown in Fi .gure 7

The PCI-DIO96 board's 24 digital I/O bits on pins 1-24 (base address +0 through +3) control the first relay
board on the chain. The 24 DIO bits on pins 25-50 control the second relay/SSR board on the daisy chain and
so on, for up to 100 pins.
