1 INTRODUCTION
The PCI-DIO96 is a 96-bit line digital I/O board. The board provides the 96 bits in
four 24-bit groups. Each group provides an 8-bit port A and port B, as well as an
8-bit port C that can be sp lit into ind ep endent 4 -bit po rt C-HI and a 4 -bit p or t C-LO.
See Figure 1-1 below.
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, you will need to install pull-down
resistors. Provisions have been made on the board to allow users to quickly and
easily install SIP resistor networks in either pull-up or pull-down configurations.

2 INSTALLATION
The PCI-DIO96 boards are completely plug-and-play. There are no switches or
jumpers on the board. All board addresses are set by your computer’s plug-and-play
software.
InstaCal is the installation, calibration and test software supplied with your data
acquisition / IO hardware. Refer to the Extended Software Installation Manual to
install InstaCal.
If you need it, there is some on-line help in the InstaCal program.
Owners of the Universal Library should read the manual and examine the example
programs prior to attempting any programming tasks.
3 I/O CONNECTIONS
3.1 CABLES AND SCREW TERMINAL BOARDS
The board has a 100-pin, high-density Robinson-Nugent male connector (Figure 3-1).
A C100FF-x cable is used to split the 100 I/O lines into two, 50-wire cables. One
connector has pins 1 to 50, the other has 51 to 100. The two I/O connectors can be
connected directly to two screw-terminal boards such as the CIO-MINI50,
CIO-TERM100, CIO-SPADE50 or SCB-50. See Figures 3-2 and 3-3 for
configuration and pin out.

3.2 CONNECTOR DIAGRAM
The PCI-DIO96 I/O connector is a 100-pin type connector accessible from the rear of
the PC at the expansion backplate See Figure 3-1 below for the board pin out.

3.3 SIGNAL CONNECTION CONSIDERATIONS
All the digital inputs on the PCI-DIO96 are 8255 CMOS TTL. The PCI-DIO96
output signals are 8255 CMOS.
OMEGA Engineering Inc. offers a wide variety of digital signal conditioning
products that provide an ideal interface between high voltage and/or high current
signals and the PCI-DIO96. If you need control or monitor non-TTL level signals
with your board, please refer to our catalog or our web site for the following
products:
CIO-ERB series, electromechanical relay output boards
CIO-SERB series, 10A electromechanical relay output boards
SSR-RACK series solid state relay I/O module racks
A description of digital interfacing is in the Interface Electronics section.
IMPORTANT NOTE
The 82C55 digital I/O chip initializes all ports as inputs on powerup 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.
There are positions for pull-up and pull-down resistor packs on your PCI-DIO96
board. To implement these, please refer to section 7.1.

3.4 CIO-ERB24 & SSR-RACK24 CONNECTIONS
PCI-DIO96 boards provide digital I/O in two major groups of 48 bits each (96 total,
but each side of the C100FF-xx cable provides 48 bits). However, many popular
relay and SSR boards provide only 24-bits of I/O. The CIO-ERB24 and
SSR-RACK24 each implements a connector scheme where all 96 bits of the
PCI-DIO96 board may be used to control relays and/or SSRs. T his configuration is
shown in Figure 3-4 below. The 24-bits of digital I/O on PCI-DIO96 connector pins
1-24 (base add ress +0 through +3) co ntrol the first relay boar d. The 24-bits on p ins
25-50 will control the second relay/SSR board on the daisy chain and so on up to
100 pins.
