Safety Instructions vii
Safety Instructions
Before handling the PCI-DIO32, read the following instructions and safety
guidelines to prevent damage to the product and to ensure your own personal
safety. Refer to the “Advisories” section for advisory conventions used in this
manual, including the distinction between Warnings, Cautions, and Notes.
Always use caution when handling/operating the computer. Only
qualified, experienced, authorized electronics service personnel should
access the interior of the computer. The power supplies produce high
voltages and energy hazards, which can cause bodily harm.
Use extreme caution when installing or removing components. Refer
to the installation instructions in this manual for precautions and
procedures. If you have any questions, please contact ICS Advent
Post-Sales Technical Support.
When Working Inside a Computer
Before taking covers off a computer, perform the following steps:
1) Turn off the computer and any peripherals.
2) Disconnect the computer and peripherals from their power sources to
prevent electric shock or system board damage.
3) Follow the guidelines provided in “Protecting Against Electrostatic
Discharge” on the following page.
4) Disconnect any telephone or telecommunications lines from the
computer.
WARNING
High voltages are present inside the chassis when the
unit’s power cord is plugged into an electrical outlet.
Disconnect the power cord from its source before removing
the chassis cover. Turning off the power switch does not
remove power to components.

viii PCI-DIO32 User’s Guide
In addition, take note of these safety guidelines when appropriate:
To help avoid possible damage to system boards, wait five seconds
after turning off the computer before removing a component, removing
a system board, or disconnecting a peripheral device from the
computer.
When you disconnect a cable, pull on its connector or on its strain-
relief loop, not on the cable itself. Some cables have a connector with
locking tabs. If you are disconnecting this type of cable, press in on the
locking tabs before disconnecting the cable. As you pull connectors
apart, keep them evenly aligned to avoid bending any connector pins.
Also, before connecting a cable, make sure both connectors are
correctly oriented and aligned.
Protecting Against Electrostatic Discharge
Static electricity can harm system boards. Perform service at an ESD
workstation and follow proper ESD procedure to reduce the risk of damage to
components. ICS Advent strongly encourages you to follow proper ESD
procedure, which can include wrist straps and smocks, when servicing
equipment. The ESD Grounding Receptacle on the chassis provides a
convenient, secure place to insert an ESD grounding strap.
You can also take the following steps to prevent damage from electrostatic
discharge (ESD):
When unpacking a static-sensitive component from its shipping
carton, do not remove the component’s antistatic packing material
until you are ready to install the component in a computer. Just before
unwrapping the antistatic packaging, be sure you are at an ESD
workstation or grounded.
When transporting a sensitive component, first place it in an
antistatic container or packaging.
Handle all sensitive components at an ESD workstation. If possible,
use antistatic floor pads and workbench pads.
Handle components and boards with care. Don’ttouch the components
or contacts on a board. Hold a board by its edges or by its metal
mounting bracket.
CAUTION
Do not attempt to service the system yourself except as
explained in this manual. Follow installation and
troubleshooting instructions closely.

3-2 PCI-DIO32 User’s Guide
Input Ports
Ports A and B are eight-bit input ports connected to optically isolated input
sensors. Each sensor can be used to interface a voltage input and sense
whether the voltage is on or off. Each sensor is isolated (with respect to a
common ground) from every other sensor, and each is 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 from 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”
internal 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. There are two things to consider when
selecting the input resistor: (1) the turn-on voltage, sensed by the circuit; and
(2) the maximum input voltage. The maximum input voltage must not provide
too much power to the input resistor, and it also must not overdrive the
opto-isolator input current specification. The following formulas apply:
Turn-on current = 3 mA
Isolator diode drop = 1.1V
Maximum resistor power = 0.25W
Turn-on voltage = diode drop + (turn-on current) x ( resistance)
Or : 1.1 + (0.003) x R
Maximum voltage = square root of (0.25 x (resistor value))

Technical Description 3-3
The following table shows four common input resistors and the ranges
associated with each:
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. The input
circuits are not intended for monitoring 120-volt AC circuits. This
voltage is too high for the circuits and dangerous to have on the card.
