2. Introduction
2.1 Overview
The 8 Input/8 Output PCI Card provides 8 reed relays
that can latch power, data and other electronic signals
for control applications. The Card also has 8 optically
isolated inputs to allow monitoring of off-board switch
closures or relays, or for any other general purpose
monitoring needs. The Card conforms to the PCI 2.1
specification.
2.2 What’s Included
The 8 Input/8 Output PCI Card comes with the
following items. If anything is missing or damaged,
please contact Black Box at 724-746-5500.
• (1) 8 Input/8 Output PCI Card
• (1) 3.5" diskette containing DIO Software

2.3 Technical Description
The 8 Input/8 Output PCI Card provides two parallel
input/output (I/O) ports. The ports are organized as
ports A, B, C, and D. Port A is an input port interfaced
to optically isolated inputs, while port C is the reed-relay
output port.
2.3.1 F EATURES
• 8 SPST relays
• One eight-bit optically isolated input port.
• DB37 male connector.
• Highly reliable 10-VA DIP reed relays used.
• Multiple adapters can reside in same computer.
• PCI 2.1 Bus compliant.
2.3.2 I NPUT P ORT
Port A is an 8-bit input port connected to optically
isolated input sensors. Each sensor can be used to
interface a voltage input and then sense whether the
voltage is on or off. Each sensor is isolated (with respect
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

11
8 INPUT/8 OUTPUT PCI CARD
to a common ground) from every other sensor, and also
isolated with respect to the host PC ground. This means
that signals such as low-voltage AC, motor-servo voltage,
and control-relay signals can be “sensed,” (or read) by
the PC without risking damage caused by ground loops
or ground faults.
Each sensor input pair has a current-limiting resistor
that is used to limit the input current to the opto-
isolator. The opto-isolator has two internal“back-to-back”
diodes. This allows AC or DC signals to be sensed,
regardless of polarity. When the applied voltage is high
enough to cause the LED in the opto-isolator to turn-on,
the output of the opto-isolator goes low (0 volts) and the
signal is read as a low logic level (binary 0) by the PC.
When the input signal is too low to turn on the opto-
isolator, the output goes high and the port bit is read by
the PC as a high logic level (binary 1).
The input impedance of each isolated input is
approximately 560 ohms (factory default). The opto-
isolator requires approximately 3 mA to turn on. The
maximum input current is 60 mA.

12
8 INPUT/8 OUTPUT PCI CARD
When selecting the input resistor, consider:
1. Power-on voltage for the circuit to sense.
2. The maximum input voltage. Maximum input
voltage must not overload the input resistor, and
must not overdrive the opto-isolator input-current
specification. The following formulas apply:
• Power-on current: 3 mA
• Isolator diode drop: 1.1 V
• Resistor power max: 0.25 W
Power-on voltage = diode drop + power-on current x
resistance
Or:
1.1 + (.003 A) x R
Maximum voltage = square root of (0.25 [resistor
value])
The table on the next page shows four common input
resistors and the ranges associated with each.

*Factory default
Increasing the input resistor can increase the maximum
input voltage. Because the PCI Card uses socketed DIP
resistor networks, they can easily be replaced (at the
factory) with a different value. The input circuits are not
intended for monitoring 120-volt AC circuits.

3. Installation
3.1 Card Setup
The 8 Input/8 Output PCI Card is a fully compliant PCI
“plug-and-play” adapter. All card resources (such as I/O
address and IRQ selection) are auto-assigned by either
your system BIOS or your plug-and-play operating
system.
3.2 Operating System Installation
Please install the proper software for your adapter
before installing the hardware. Refer to the supplied
software for the correct operating system installation
procedure.
3.3 System Installation
You can install the 8 Input/8 Output PCI Card in any of
the PCI expansion slots. To install the Card:
1. Turn off the PC’s power. Disconnect the power
cord.
2. Remove the PC case cover.

15
8 INPUT/8 OUTPUT PCI CARD
3. Locate an available PCI slot and remove the screw
that secures the blank metal slot cover. Remove
the cover.
4. Gently insert the PCI Card into the slot. Make sure
that the Card is seated properly.
5. Replace the screw.
6. Replace the cover.
7. Connect the power cord. Installation is complete.

4.2 Output Port (Reed Relay)
Reed relays provide very high quality, long life, low
current (0.5 amps max.), dry-contact switch closures.
Reed relays are not suited for high-current applications,
and can be destroyed by inductive load switching where
a spark occurs across the contacts internally. The relays
are normally open; then close when energized. Writing a
“1” to the proper port bit can individually energize each
relay.

4.6 Software
The 8 Input/8 Output PCI Card ships with an I/O suite
of Windows®95, 98, and NT drivers. The software
provides a consistent and straightforward API, so the
developer can concentrate on the details of the
application instead of low-level driver development.
Popular development environments, including Visual
C++, Visual Basic, and Delphi, are supported for
application development. The software includes a utility
for configuring the driver parameters under Windows
NT. Configuration is automatic with Windows 95 or 98.
For DOS, and other operating systems, please refer to
the software included with your card.
