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.

Unpacking the CYDIO 96HE
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the CYDIO 96HE from its packaging, ground yourself using a wrist strap or by
simply touching the computer chassis or other grounded object to eliminate any stored static charge.
If your CYDIO 96HE is damaged, notify CyberResearch, Inc. immediately by phone, fax, or e-mail.

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

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.
