Warranty
Prior to shipment, ACCES equipment is thoroughly inspected and tested to applicable specifications.
However, should equipment failure occur, ACCES assures its customers that prompt service and support
will be available. All equipment originally manufactured by ACCES which is found to be defective will be
repaired or replaced subject to the following considerations.
Terms and Conditions
If a unit is suspected of failure, contact ACCES' Customer Service department. Be prepared to give the
unit model number, serial number, and a description of the failure symptom(s). We may suggest some
simple tests to confirm the failure. We will assign a Return Material Authorization (RMA) number which
must appear on the outer label of the return package. All units/components should be properly packed for
handling and returned with freight prepaid to the ACCES designated Service Center, and will be returned
to the customer's/user's site freight prepaid and invoiced.
Coverage
First Three Years: Returned unit/part will be repaired and/or replaced at ACCES option with no charge for
labor or parts not excluded by warranty. Warranty commences with equipment shipment.
Following Years: Throughout your equipment's lifetime, ACCES stands ready to provide on-site or in-plant
service at reasonable rates similar to those of other manufacturers in the industry.

Equipment provided but not manufactured by ACCES is warranted and will be repaired according to the
terms and conditions of the respective equipment manufacturer's warranty.
General
Under this Warranty, liability of ACCES is limited to replacing, repairing or issuing credit (at ACCES
discretion) for any products which are proved to be defective during the warranty period. In no case is
ACCES liable for consequential or special damage arriving from use or misuse of our product. The

Chapter 1: Introduction
Features
• Individually-Isolated AC/DC Inputs for two 24-bit groups, 48 total
• Reverse Polarity protection
• AC Filtering (first 24 channels)
• Optical Isolation, Channel-to-Channel and Channel-to-Host PC
•
Change-of-State detection (certain models)
Description
This series of boards provides 48 optically-isolated inputs for AC/DC signals with Change-of-State (COS)
Detection capability. Each input is reverse polarity protected and rectified by photo-coupler diodes.
Standard 12/24 AC control transformer outputs can be accepted on the first 24 channels as well as DC
voltages on all 48. The input range is up to 60VDC or AC RMS at frequencies of 40 to 10kHz.
The first 24 input circuits contain a switchable filter that has a 4.7 millisecond time constant (without
filtering, the response is less than 30 microseconds). The filter must be selected for AC inputs in order to
eliminate the on/off response to AC. The filter is also valuable for use with slow DC input signals in a
noisy environment. The filter may be switched out for DC inputs in order to obtain a faster response.
Filters are individually selected by jumpers. See Figures 1-1 and 3-1 for jumper arrangements.
The Change-of-State (COS) Detection capability (denoted by a “C” after the model number) provides a
means to automatically interrupt the host computer in real time. When one or more input bits change
state, a PCI interrupt is generated. That interrupt, in turn, can be used by your application program to
initiate a poll of the inputs, then signal appropriate alarms, and/or initiate a scan of other I/O points that
have not been previously activated. This can greatly simplify your application program and eliminate need
to continuously poll inputs. Chapter 5 describes the programming aspects of the COS feature.
These boards provide a much lower cost per point than externally-mounted, optically-isolated, solid-state
modules or PLCs. Input connections are via 50-pin ribbon-cable headers on the card.
These boards are especially useful in applications where high-common-mode external voltages are
present as found in factory automation, energy management, security systems, and process monitoring
applications. In addition to protecting your computer from accidental contact with high external
voltages, the isolation provided eliminates troublesome ground loops.
Letters are appended to the model numbers to signify options (described above) included on the card.
Refer to Table 1-1 for model-specific information.

**Note on Isolation: Opto-Isolators and connectors are rated for at least 500V, but isolation voltage
breakdowns will vary and is affected by factors like cabling, spacing of pins, spacing between traces on
the PCB, humidity, dust and other environmental factors. This is a safety issue so a careful approach is
required. For CE certification, isolation was specified at 60V DC or AC rms. The design intention was to
eliminate the influence of common mode. Use proper wiring techniques to minimize voltage between
channels and to ground. Tolerance of higher isolation voltage can be obtained on request by applying a
conformal coating to the board.

Chapter 2: Installation
A printed Quick-Start Guide (QSG) is packed with the board for your convenience. If you’ve already
performed the steps from the QSG, you may find this chapter to be redundant and may skip forward to
begin developing your application.
The software provided with this PC/104 Board is on CD and must be installed onto your hard disk prior to
use. To do this, perform the following steps as appropriate for your operating system. Substitute the
appropriate drive letter for your CD-ROM where you see d: in the examples below.
CD Installation
The following instructions assume the CD-ROM drive is drive “D”. Please substitute the appropriate drive
letter for your system as necessary.
DOS
1. Place the CD into your CD-ROM drive.
2. Type B- to change the active drive to the CD-ROM drive.
3. Type GLQR?JJ- to run the install program.
4. Follow the on-screen prompts to install the software for this board.
WINDOWS
1. Place the CD into your CD-ROM drive.
2. The system should automatically run the install program. If the install program does not
run promptly, click START | RUN and type BGLQR?JJ, click OK or press -.
3. Follow the on-screen prompts to install the software for this board.
LINUX
1. Please refer to linux.htm on the CD-ROM for information on installing under linux.

Installing the Hardware
Before installing the board, carefully read Chapter 3 and Chapter 4 of this manual and configure the
board according to your requirements. The SETUP Program can be used to assist in configuring jumpers
on the board. Be especially careful with Address Selection. If the addresses of two installed functions
overlap, you will experience unpredictable computer behavior. To help avoid this problem, refer to the
FINDBASE.EXE program installed from the CD. The setup program does not set the options on the
board, these must be set by jumpers.
To Install the Board
1. Install jumpers for selected options and base address according to your application requirements,
as mentioned above.
2. Remove power from the PC/104 stack.
3. Assemble standoff hardware for stacking and securing the boards.
4. Carefully plug the board onto the PC/104 connector on the CPU or onto the stack, ensuring
proper alignment of the pins before completely seating the connectors together.
5. Install I/O cables onto the board’s I/O connectors and proceed to secure the stack together or
repeat steps 3-5 until all boards are installed using the selected mounting hardware.
6. Check that all connections in your PC/104 stack are correct and secure then power up the
system.
7. Run one of the provided sample programs appropriate for your operating system that was
installed from the CD to test and validate your installation.
