Three types of advisories are used throughout the manual to stress important points or warn of potential
hazards to the user or the system. They are the Note, the Caution, and theWarning. Following is an example
of each type of advisory:
Note: The note is used to present special instruction, or to provide extra information which may
help to simplify the use of the product.
CAUTION!
A Caution is used to alert you to a situation which if ignored may cause injury or
damage equipment.
WARNING!
AWarningisusedtoalertyouofasituationwhichifignoredwillcauseseriousinjury.
Cautions and Warnings are accented with triangular symbols. The exclamation symbol is used in all cautions
and warnings to help alert you to the important instructions. The lightning flash symbol is used on the left
hand side of a caution or a warning if the advisory relates to the presence of voltage which may be of
sufficient magnitude to cause electrical shock.
Use caution when servicing any electrical component. We have tried to identify the areas which may pose
a Caution or Warning condition in this manual; however, ICS Advent does not claim to have covered all
situations which might require the use of a Caution or Warning.

Chapter 1: Functional Description
Manual Number: 00650-014-4 Page 1-1
Chapter 1: Functional Description
The AD12-8 is a multifunction, moderate-speed analog-to-digital converter card with counter/tim-
ers and digital I/O ports. This card may be used in any PC compatible computer. The card is seven
inches long and requires one slot in the computer. All external connections are made through a
standard 37-pin D-type connector at the rear of the computer. The following paragraphs describe
the functions provided by the AD12-8 card.
Analog Inputs
The card accepts eight single-ended analog input channels. The full scale input for all channels is
jumper selectable, either ±10V (0.00488V resolution), or ±5V (0.00244V resolution), or unipolar
0 to 10V (0.00244V resolution). Inputs are single-ended with a common ground and can withstand
overvoltages up to ±30 volts and brief transients of several hundred volts. When power is off, the
inputs are open-circuited providing fail-safe operation. The analog-to-digital converter (A/D) is a
12-bit successive-approximation type with a sample and hold input. Conversion time is typically
25mS (35mS maximum) and, depending on the speed of the software and computer platform, through-
puts of up to 40,000 conversions per second are attainable.
Input System Expansion
The AD12-8 card may be used alone or it can support up to eight AT16-P or LVDT8-P analog input
expansion cards. An 8-bit standard LSTTL logic output from the AD12-8 is used to control the
AT16-P (These outputs are separate from the discrete I/O lines discussed later.). Four bits are used
to select one of 16 analog input channels at the AT16-P. Three bits are used to select one of eight
gains for the selected input channel. The remaining bit is a digital output (sink current 8mA, source
current 0.4mA). When interfacing to the LVDT8-P, three bits are used to select one of eight
LVDT8-P inputs. Since the eight-input multiplexer on the AD12-8 card is software addressable, an
input expansion card may be connected to each input, for a maximum of 128 channels in the
system. If more than 128 analog inputs are required, a second AD12-8 with companion input
expansion cards can be used.
Discrete Digital I/O
The AD12-8 card provides eight bits of individually jumper-programmed digital input and/or out-
put. The outputs can sink 24mA or source 2.6mA. For ease of use, we suggest that you use the
Screw Terminal Accessory Board, model UTB to make external connections.
Reference Voltage Output
A precision +10.0V (±0.1V) reference voltage output is derived from the A/D converter reference.
The reference voltage is buffered and will source up to 220mA, which is sufficient for exciting
several strain gage sensors, load cells, or other transducers.

AD12-8 Manual
Counter/Timer
The AD12-8 includes a type 8253 counter/timer which has three 16-bit programmable synchro-
nous down counters. This chip is used for event counting, pulse and waveform generation, fre-
quency and period measurement etc. A/D conversion cycles may be initiated by the Counter/Timer
by installing the TMR/EXT jumper in the TMR position. Counter #1 is connected to a 1/32 mul-
tiple of the computer color Oscillator clock (14.31818MHz). The output of counter #1 is used as
the clock for Counter #2 and also Counter #0 when so configured by installing the CLK0 jumper.
Counter #0 is fully accessible for general purpose use.
Interrupts
Interrupts are supported from either external inputs or A/D conversion completion. Selection of
the interrupt source and interrupt levels (IRQ2-7), is made by jumper. Interrupts are software
enabled and disabled. An interrupt request may be canceled by one or more of the following three
signals:
a. The computer reset signal.
b. The beginning of an A/D conversion cycle.
c. The writing of a command word to the card. That is, either updating the gain or channel
selection multiplexer on the AT16-P expansion card, or the AD12-8 multiplexer.
Utility Software
Utility software included with the AD12-8 is provided in MS-DOS format on a diskette. A pro-
gram named FINDBASE can help you to select the base address for the card. Two menu-driven
setup programs, DOS drivers in linkable object form and binary form, a VisualBASIC utility driver,
and sample programs are provided. One setup program is a configuration and calibration tool for
the AD12-8, and the second setup program is used when an AT16-P and/or LVDT8-P is used in
conjunction with the AD12-8. In the case of the AT16-P, gains are assignable on a channel-by-
channel basis. Linearization for all the commonly used thermocouple types as well as for platinum
RTDs is also menu selectable.
A driver configuration file is generated or modified by the setup program and can be used to
configure the AD12-8 driver. CHAPTER 2: SYSTEM SOFTWARE describes the format of this
configuration file. This driver has 17 Tasks as will be described in detail in CHAPTER 5: AD12-
8 DRIVER REFERENCE of this manual.
Sample programs are provided in BASIC, QuickBASIC, Pascal and C.

Chapter 1: Functional Description
Manual Number: 00650-014-4 Page 1-3
Enhancements
Capabilities of the AD12-8 can be greatly enhanced by use of one or more of the following hard-
ware devices or software packages:
a. UTB Screw Terminal Cards.
This terminal board allow direct input/output signal connections via screw terminals. The card
also provides a breadboard area with ±12V and +5V computer power. This breadboard area
can be used for amplifiers, filters, and other user-assembled circuits.
b. AT16-P Expansion Multiplexer and Instrumentation Amplifier
The AT16-P is a 16-channel amplifier/multiplexer that features differential or single-ended
input capability and a choice of either DIP switch selectable gains or software programmable
gains. The AT16-P allows multiplexing of 16 analog input signals to a single AD12-8 analog
input channel. As described earlier, up to eight AT16-Ps can be connected to a single AD12-
8 to provide input capability for up to 128 analog inputs.
The AT16-P includes a low-drift instrumentation amplifier with DIP switch selectable gains of
0.5, 1, 2, 5, 10, 25, 50, 100, 200, 500, and 1000. In addition, these gains can be software
programmed to provide individual gains on a channel-by-channel basis.
For thermocouple measurements, a cold junction sensor is provided to allow reference junction
compensation, via software, for thermocouple inputs. The reference junction output may be
assigned to channel 0 of the AT16-P or, alternatively, may be jumpered to an unused AD12-8
input channel. Open-thermocouple or break detect circuitry is provided.
The AT16-P may also be used with 3-wire RTDs, strain gages, and 4-20mA current transmitter
inputs. In this latter case, an application-specific version, the AT16I-P, is available.
c. LVDT8-P Multiplexer and Interface Card
This card provides AC excitation and signal conditioning to eight independent LVDT
transducers. As many as eight LVDT8-Ps may be connected to an AD12-8 to accommodate
up to 64 transducers.
d. SSH-04/-08 Simultaneous Sample and Hold Card
These cards install external to the computer and contain four and eight identical sample and
hold circuits respectively. Each circuit consists of a differential-input, programmable-gain
amplifier and a sample and hold amplifier. Outputs of the sample and hold amplifiers are
coupled through a multiplexer and a common buffer amplifier.

How to remain CE Compliant
In order for machines to remain CE compliant, only CE compliant parts may be used. To keep a
chassis compliant it must contain only compliant cards, and for cards to remain compliant they
must be used in compliant chassis. Any modifications made to the equipment may affect the CE
compliance standards and should not be done unless approved in writing by Industrial Computer
Source.
The Model AD12-8 is designed to be CE Compliant when used in an CE compliant chassis.
Maintaining CE Compliance also requires proper cabling and termination techniques. The user is
advised to follow proper cabling techniques from sensor to interface to ensure a complete CE
Compliant system. Industrial Computer Source does not offer engineering services for designing
cabling or termination systems. Although Industrial Computer Source offers accessory cables and
termination panels, it is the user's responsibility to ensure they are installed with proper shielding
to maintain CE Compliance.

Software Provided
The following utility software is provided with AD12-8 in MS-DOS format on a 3.5-inch diskette.
a. A program named FINDBASE to help you locate a convenient base address for the card
b. A menu-driven setup and calibration program SETA12.EXE.
c. A menu-driven setup and calibration program for the sub-multiplexer cards, SETMUX.EXE.
d. Software drivers are included in a directory labeled DRIVERS; a BASIC loadable file called
A12DRV.BIN, a C language linkable file called A12DRVC.OBJ, and a QuickBASIC and
Pascal linkable file called A12DRV.OBJ. All forms of the driver were created using Turbo
Assembler, by Borland.
e. Sample programs in QuickBASIC (B Samples), C (C Samples), and Pascal (P Samples).
f. A VisualBASIC Utility driver
g. A Microsoft Windows driver in DLL form.
h. Windows sample programs in both C and Visual BASIC.
i. A demonstration program for Windows.
Backing up the Master Diskettes
As with any software package, you should make backup copies for everyday use and place your
original master diskettes in a safe location. The easiest way to make a backup copy is to use the
DOS DISKCOPY utility.
In a single drive system the command is:
DISKCOPY A: A:
You will need to swap disks as requested by the system.
In a two-disk system the command is:
DISKCOPY A: B:
This will copy the contents of the master disk in drive A to the backup disk in drive B.

Hard Disk Installation
The files contained on the master diskette may also be copied onto your hard disk. To do this
perform the following:
1. Place the master diskette into a floppy drive.
2. Change the active drive to the drive that has the master diskette installed. For example, if the
diskette is the A drive, type A:
3. Type INSTALL and follow the screen prompts.
Files contained on the disk are stored in separate directories as follows:.
ROOT: Contains the FINDBASE PROGRAM that will help you to decide what
base address to use with the card. Also contains the SETA12.EXE setup and
calibration program, the SETMUX.EXE sub-multiplexer card setup and
calibrationprogram, andPOLY.EXE,the linearizationpolynomialprogram.
PSAMPLES: Contains Pascal samples and the Pascal-linkable driver.
CSAMPLES: Contains C samples and the C-linkable driver.
BSAMPLES: Contains the BASIC and QuickBASIC samples as well as the binary and
linkable drivers.
VBWIN: Contains the Windows Visual BASIC samples.
CPPWIN: Contains the Windows C samples.
Configuration File
The Configuration File has several purposes; most of which are associated with use of the software
drivers provided with your AD12-8 card. These are as follows:
a. Provide means to automatically configure the driver and, thus, avoid need for multiple calls to
the driver to do the setup.
b. Allow the setup programs to do the work of configuring the driver. When you use the setup
programs to assist in configuring the card, this information is saved in the configuration file
and can then be used by the drivers.
The Configuration File, SETUP.CFG, is generated or modified with the setup programs. It can also
be generated or modified by an editor or a word processor in the non-document mode. This file is
a structured file containing setup information for:
a. AD12-8 plug in PC card.
b. AT-16 sub-multiplexer card.
c. LVDT8-P sub-multiplexer card.
d. Programmable gain assignments.
e. Curve assignments.
