Chapter 1
Introducing the CYDIO 96HE
Overview: CYDIO 96HE features
This manual explains how to install and use the CYDIO 96HE board. The CYDIO 96HE is a high-density,
logic-level digital I/O board designed for PCI Express (PCIe) bus.
The CYDIO 96HE provides 96 digital I/O lines in four independent port groups. Each digital port group is
divided into two 8-bit ports and two 4-bit ports. The CYDIO 96HE emulates an 82C55 chip in Mode zero. You
can configure each port independently for either input or output.
The CYDIO 96HE outputs are high-drive TTL that can source 15 mA and sink 64 mA. Additional buffering is
typically not required to drive external devices. The board has two individual slow blow fuses rated at 1 amp
that provide protection for the +5 V User Outputs. A spare fuse is provided.
Each digital port has an associated 10 k resistor network. The board is shipped with each port configured in the
pull-up state. You can change the port configuration with software. On power up and reset the configuration of
each port is read from EEPROM.
Digital I/O lines are accessed through a 100-pin high-density connector.
The CYDIO 96HE board is completely plug-and-play, with no jumpers or switches to set. All board addresses
are set by the board's plug-and-play software. Board configuration is controlled by your system's BIOS.
Power is provided by the computer’s internal 5 V Molex connector.

Installing the software
Install the software included with your board before you install the hardware. Installing the software first
ensures that the information required for proper board detection is installed and available at boot up.
Installing the hardware
The CYDIO 96HE is completely plug-and-play. There are no switches or jumpers to set on the board.
Configuration is controlled by your system's BIOS. To install your board, follow the steps below.
Install the CYBERDAQ software before you install your board
The driver needed to run your board is installed with the CYBERDAQ software. Therefore, you need to install
the CYBERDAQ software before you install your board. Power off and unplug the computer, and remove the
cover to expose the expansion slots.
1. Touch any metal part of the computer to discharge static electricity that may be present. Static electricity
can damage the board.
2. Insert the CYDIO 96HE into an unused x1 PCIe expansion slot.
The CYDIO 96HE is designed to install into an x1 slot. However, you can also install the board into an
unused x4, x8, or x16 PCIe slot.
Caution! Ensure that you install the board into a PCI Express slot. Installing the CYDIO 96HE into a non-
PCIe slot can damage both the board and the computer’s motherboard.
3. Connect the board’s external power connector to one of the computer’s four-pin Molex power connectors.
The board’s Molex power connections are shown here.
No PC PC PC
Connect
Ground Ground +5V
Caution! Using an external power supply is not recommended. If external power is used, ensure that the
power supply ground or common is at the same ground potential as the computer power supply.

4. Close your computer and turn it on.
A dialog box opens as the system loads, indicating that new hardware has been detected. The information
file for this board should have already been loaded onto your PC when you installed the Software CD
supplied with your board, and should be detected automatically by Windows. If you have not installed this
software, cancel the dialog and install it now.
5. Run InstaCal to test your installation and to configure the pull direction of the digital port resistors.

The CYDIO 96HE has a 100-pin, high-density Robinson-Nugent male connector. You can use the CBL 100xx
cable to split the 100 I/O lines into two 50-pin cables (see Figure 2 on page 9).
Board connector pins 1 to 50 are mapped directly to pins 1 to 50 on the CBL 100xx cable's first 50-pin
connector. Pins 51 to 100 are mapped directly to pins 1 to 50 on the second 50-pin connector (pin 51 is mapped
to pin 1, and pin 100 is mapped to pin 50.) A sample CBL 100xx cable configuration is shown in Figure 3 on
page 9.
Caution! When connecting a cable to the board's I/O connector, make sure that the arrow indicating pin 1
on the board connector lines up with the arrow indicating pin 1 on the cable connector. Incorrectly
connected cables can damage the board and the I/O controller.

Functional Details
CYERB 24 and CYSSR 24 daisy chain configuration
Many relay and solid-state relay (SSR) racks provide only 24-bits of digital I/O. You can configure the CYERB
24 relay output board and CYSSR 24 I/O module rack in a daisy chain configuration to use all of the digital I/O
bits provided by the CYDIO 96HE board. An example of the daisy chain configuration scheme for each board
is shown below.
The CYDIO 96HE board provides digital I/O in a group of 96 bits. Each of the CBL 100xx cable'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 Figure 4.

The 24 digital I/O bits on pins 1-24 control the first relay board on the chain. The 24 digital I/O bits on pins
25-50 control the second relay/SSR board on the daisy chain and so on, for up to 100 pins.
82C55 emulation (mode 0)
The CYDIO 96HE emulates the 82C55 chip (mode 0). The 82C55 emulation 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
output, it could be turned on or off every time the board is reset.
To establish a consistent TTL level at power-up, configure each port resistor with InstaCal for either pull-up or
pull-down.
Whenever an 82C55 emulation is powered on or reset, all pins are set to high-impedance input. Based on
standard TTL functionality, these inputs typically float high, and may have enough drive current to turn on
external devices. Consequently, if you have output devices such as solid state relays, they may be switched on
whenever the computer is powered on or reset. To prevent unwanted switching, and to drive all outputs to a
known state after power on or reset, configure each port resistor with InstaCal.
Unconnected inputs are forced to the pull direction
Unconnected inputs will float in the pull direction that is configured for the port with InstaCal (either up/high or
down/low).

Product Service
Diagnosis and Debug
CyberResearch, Inc. maintains technical support lines staffed by experienced
Applications Engineers and Technicians. There is no charge to call and we will
return your call promptly if it is received while our lines are busy. Most problems
encountered with data acquisition products can be solved over the phone. Signal
connections and programming are the two most common sources of difficulty.
CyberResearch support personnel can help you solve these problems, especially if
you are prepared for the call.
To ensure your call’s overall success and expediency:
1) Have the phone close to the PC so you can conveniently and quickly take
action that the Applications Engineer might suggest.
2) Be prepared to open your PC, remove boards, report back-switch or jumper
settings, and possibly change settings before reinstalling the modules.
3) Have a volt meter handy to take measurements of the signals you are trying
to measure as well as the signals on the board, module, or power supply.
4) Isolate problem areas that are not working as you expected.
5) Have the source code to the program you are having trouble with available
so that preceding and prerequisite modes can be referenced and discussed.
6) Have the manual at hand. Also have the product’s utility disks and any
other relevant disks nearby so programs and version numbers can be
checked.
Preparation will facilitate the diagnosis procedure, save you time, and avoid
repeated calls. Here are a few preliminary actions you can take before you call
which may solve some of the more common problems:
1) Check the PC-bus power and any power supply signals.
2) Check the voltage level of the signal between SIGNAL HIGH and
SIGNAL LOW, or SIGNAL+ and SIGNAL– . It CANNOT exceed the full
scale range of the board.
3) Check the other boards in your PC or modules on the network for address
and interrupt conflicts.
4) Refer to the example programs as a baseline for comparing code.
