RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio frequency energy and if not
installed and used properly, that is, in strict accordance with the manufacturer’s
instructions, may cause interference to radio communication. It has been tested
and found to comply with the limits for a Class A computing device in accordance
with the specifications in Subpart B of Part 15 of FCC rules, which are designed to
provide reasonable protection against such interference when the equipment is
operated in a commercial environment. Operation of this equipment in a
residential area is likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be necessary to correct the
interference.
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from digital
apparatus set out in the Radio Interference Regulation of Industry Canada.

DIGITAL I/O CARD–16
2. Introduction
2.1 Overview
The Digital I/O Card–16 provides 16 reed relays that can latch power, data, or
other electronic signals for control applications and 16 optically isolated inputs to
allow monitoring of off-board switch closures, relays, or for any other general-
purpose monitoring needs. The card is PCI 2.1 bus compliant. Addressing, data,
and control signals are TTL compatible.
2.2 What’s Included
The Digital I/O Card–16 is shipped with the following items. If any of these items
are missing or damaged, contact Black Box at 724-746-5500.
• Digital I/O Card–16
• Systems software (on a CD-ROM)
• This users’ manual
2.3 Technical Description
The Digital I/O Card–16 provides four parallel input/output (I/O) ports. The
ports are organized as ports A, B, C, and D. Ports A and B are input ports
interfaced to optically-isolated inputs, while ports C and D are reed relay output
ports. Assuming an I/O address of 300 Hex, Table 2-1 shows the port addresses.
Table 2-1. Port addresses.
Base Address Hex Decimal Mode
Port A Address 300 768 Input Port (Opto-Input)
Port B Address 301 769 Input Port
Port C Address 302 770 Output Port (Reed Relays)
Port D Address 303 771 Output Port

CHAPTER 2: Introduction
2.3.1 F EATURES
• Selectable I/O port addressing from 100H through 3FFH.
• Two sets SPST relays (each set has eight relays).
• Two eight-bit input ports.
• DB37 male connector for relay outputs.
• DB37 female connector for optically isolated inputs.
• Highly reliable 10-VA DIP reed relays used.
• Multiple adapters can reside in same computer.
• All address, data, and control signals are TTL compatible.
2.3.2 I NPUT P ORTS
Ports A and B are 8-bit input ports 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 to a common ground)
from every other sensor, and it’s also isolated with respect to the host PC ground.
This means that signals such as low-level AC line voltage, motor servo voltage, and
control relay signals can be “sensed,” or read by the PC, without the risk of damage
due to 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 “back-to-back” diodes
internally. 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 power
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 power on the
opto-isolator, the output goes high and the port bit is read by the PC as a high
logic level (binary 1).

10
DIGITAL I/O CARD–16
The input impedance of each isolated input is approximately 560 ohms (factory
default). The opto-isolator requires approximately 3 mA to power on. The
maximum input current is 60 mA. You must consider two things when selecting the
input resistor: The first is power-on voltage for the circuit to sense, and second is
the maximum input voltage. Maximum input voltage must not provide too much
power to the input resistor, and it must also 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 + (turn-on current) x ( resistance)
Or :
1.1 + (.003) x R
Maximum voltage = square root of (0.25 [resistor value])
Table 2-2 shows four common input resistors and the ranges associated with each.
Table 2-2. Input resistor ranges.
Input Resistor Value Power-On Max. Input Range Max. Current
(ohms) (volts) (volts) (mA)
220 1.76 7 27
560 2.8 12 20
1K 4.1 16 15
2.2K 7.7 24 10
The maximum input voltage can be increased by increasing the input resistor
accordingly. Because socketed DIP resistor networks are used, they can easily be
replaced with a different value. This can be done at the factory, if necessary. The
input circuits are not intended for monitoring 120-volt AC circuits. In addition to
being too high a voltage for the circuits, it is dangerous to have that high a voltage
on the card.
Table 2-3 lists the input ports pin assignments.

UTPUT P ORTS
(R EED R ELAY )
Reed relays provide very-high-quality, long-life, low-current (10-watt maximum),
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, and they close when energized.
Each relay can be individually energized by writing a “1” to the proper port bit.
Table 2-4 shows the output ports’ pin assignments.

DIGITAL I/O CARD–16
2.3.4 S OFTWARE
The Digital I/O Card–16 ships with an I/O suite of Windows®98/Me/XP,
Windows NT®, and Windows 2000 drivers. These drivers provide you with a
consistent and straightforward application program interface (API), allowing the
developer to concentrate on the details of the application as opposed to low-level
driver development. Popular development environments, including Visual C++,
Visual Basic, and Delphi, are supported for application development. I/O includes
a utility for configuring the driver parameters under Windows, further simplifying
installation.
For DOS, QNX, Linux®and other operating systems, please refer to the software
included with your card.
Programming Examples
All examples assume a base address of 300 Hex.
To read inputs at port A :
MOV DX,300H ;Set DX to Port A
IN AL,DX ;Get Input Port Data
NOT AL ;data read is negative
logic
Programming example to set Relay #3 on, write a “1” in bit position D3, to port
address Base+3, or 303 Hex.
MOV DX, 303H ;Set DX to Port D
MOV AL, 00001000B ;Set bit 3 to a ‘1’
OUT DX, AL
Another method that takes into account the read-back capability of the output
ports C and D:
MOV DX,303H ;Set DX To Port D
IN AL,DX ;Get old port setting
NOT AL :Invert bits- see note below
OR AL,00001000B ;OR in bit 3
OUT DX,AL ;Set Bit 3
NOTE
Reading back the ports (C and D) results in the binary complement of
the output.

NOTE
All ports are set to input after reset or power-up. Interrupt source is
Base+0 bit D0. When selecting the Interrupt Mode, always disable
interrupts before changing or setting states. This will help prevent
inadvertent or unexpected interrupts from occurring. When using the
high- and low-level interrupts, a change in state of the input must occur
before the interrupt can be cleared. The device providing the input to
Base+0, bit D0, must do this.

Chapter 3.
To install the card:
1. Turn off all PC power and disconnect the power cord.
2. Remove the cover of the PC case.
3. Locate two available slots and remove the blank metal slot covers.
4. Gently insert the Digital I/O Card–16 into the slot. Make sure the card is
seated properly. Insert the cable bracket into the adjacent slot and screw it in
place.
5. Replace the PC’s cover.
6. Connect the power cord.
Installation is complete.

APPENDIX A: Troubleshooting
Appendix A. Troubleshooting
Following these simple steps can eliminate most common problems without the
need to call Technical Support.
1. Install software first. After installing the software, add the hardware. This
places the required installation files in the correct locations.
2. Identify all I/O adapters currently installed in your system. This includes your
onboard serial ports, controller cards, sound cards, etc. The I/O addresses
used by these adapters, as well as the IRQ (if any), should be identified.
3. Make sure that there is no conflict with currently installed adapters. No two
adapters can occupy the same I/O address and may not be allowed to share
IRQs.
4. Make sure the system’s adapter is securely installed in a motherboard slot.
