2.1 INSTALL THE InstaCal SOFTWARE PACKAGE
2.1.1 INTRODUCTION
InstaCal is the installation, calibration and test software supplied with your data acquisition / IO hardware. The complete InstaCal package is also included with the Universal Library. If you have ordered the Universal Library, use the Universal Library
disk set to install InstaCal. The installation will create all required files and unpack
the various pieces of compressed software. To install InstaCal, simply run setup.exe,
and follow the on-screen instructions.
2.1.2 INSTALLATION OPTIONS
If you are installing on a Windows 95 or 98 operating system, the "Installation
Options" dialog box will allow you to install the 16 bit, the 32 bit or both versions of
InstaCal. Select the 32 bit version unless you intend to use a 16 bit application or
library to control your data acquisition hardware.
If you are installing from the Universal Library disk set, the "Installation Options" dialog box also presents options to install example programs for each language
supported. Select the appropriate example programs for the language you will be
using.
2.1.3 FILE DEFAULT LOCATION
InstaCal will place all appropriate files in "C:\CB." If you change this default location
remember where the installed files are placed as you may need to access them later.
2.1.4 INSTALLATION QUESTIONS
At the end of the installation process there will be a series of questions: unless you
have knowledge to the contrary, simply accept the default when prompted.
2.1.5 INSTALLATION COMPLETION
After the installation of InstaCal is complete you should restart your computer to take
advantage of changes made to the system.

3 WINDOWS 3.X OR DOS INSTALLATION
3.1 INSTALL THE InstaCal SOFTWARE PACKAGE
InstaCal is the installation, calibration and test software supplied with your data acqui-
sition / IO hardware. The complete InstaCal package is also included with the Universal Library. If you have ordered the Universal Library, use the Universal Library
disk set to install Instacal. The installation will create all required files and unpack the
various pieces of compressed software. To install InstaCal, simply run setup.exe, and
follow the on-screen instructions.
3.1.1 INSTALLATION OPTIONS
If you are installing from the Universal Library disk set, the "Installation Options" dialog box presents options to install libraries and example programs for each language
supported. Select the appropriate library version and example programs for the language you will be using.
If your computer does not have the Windows operating system installed (only the
DOS operating system is available), install the separate DOS-only InstaCal package
called "InstaCal for DOS, Universal Library for DOS" available from your vendor.
Computers running Windows 3.x and/or DOS need to use the DOS based Card &
Socket Services (CSS) drivers. CSS is included with most newer computers, but if
you need to purchase these drivers, they are available from your vendor (order PCM
CSS). During the InstaCal installation, you will be prompted to indicate whether or
not to install CBCLIENT. Respond "Yes." CBCLIENT is used by CSS to configure
the PCMCIA data acquisition cards. Remember, if you do not have CSS loaded,
install it before attempting to use the PCMCIA card. More information about CSS is
available in section 3.5 titled "About DOS Card & Socket Services."
InstaCal will place all appropriate files in "C:\CB." If you change this default location
remember where the installed files are placed as you may need to access them later.
At the end of the installation process there will be a series of questions: unless you
have knowledge to the contrary, simply accept the default when prompted.
After the installation of InstaCal is complete you should restart your computer to take
advantage of changes made to the system.

3.5 ABOUT DOS CARD & SOCKET SERVICES
The following section describes Card & Socket Services and should help you determine whether or not you need to install CSS.
Some operating systems, such as Windows 95, include an integrated version of CSS.
If you are running such an o pera ting system, do no t install D OS CSS unless you ha ve
a specific reason to do so.
Card and socket services for your PCM card are on a disk labeled "DOS Card &
Socket Services." The software from that disk should be installed if you do not
already have CSS support on your PC.
3.5.1 WHAT IS CSS?
CSS is a program that communicates with your computers PCMCIA interface controller and configures it. The PCMCIA interface is configurable, unlike the standard ISA
8
bus you may be familiar with. If you plug a PCMCIA board into a PCMCIA slot and
have not yet run CSS, you will have no access to the functions of that PCMCIA board.
3.5.2 DOES CSS USE SYSTEM RESOURCES?
Yes. The CardSoft Card and Socket Services device drivers which are installed in
your CONFIG.SYS use about 61K of memory. These files can be installed
DEVICEHIGH.
The CBCLIENT.EXE installed in your AUTOEXEC.BAT uses about 10K of
memory. The CBCLIENT.EXE program is a TSR (Terminate and Stay Resident).
You may modify the program line to LOADHIGH the TSR. We have tested it both
high and low with and without Windows and a variety of other applications. We
believe it is a safe TSR that will not cause any system problems.
3.5.3 HOW DO I KNOW CSS IS INSTALLED AND RUNNING?
There is a simple test. Just plug in your PCM-card. If CSS is installed and working
the computer will beep. You can remove and replace your PCM-card as often as you
like and need not power down to do so. The computer should beep each time you
insert the PCM-card.
3.5.4 WHAT ABOUT CSS FOR MULTIPLE PCM BOARDS?
Once the current version of CSS is installed, CSS is installed for all PCM boards
included in that version of CSS. As new PCM boards become available, they will be
added to the CSS and you will want to always have the most recent version of
CBCLIENT.EXE installed in the C:\CB directory. Let the installation software do
this for you.
You can run multiple PCMCIA boards with the CBCLIENT.EXE CSS, and, if you
have another CLIENT program running for other PCMCIA boards, it will not
interfere.

4 INTERFACING
The PCM-DAC08 has 8 single ended analog outputs, 9 analog grounds, 1 interrupt
input, 8 digital inputs/outputs, 1 +5V output and 6 digital grounds. A chassis ground
is in the cable shield clips to either side of the 33 pins of the connector.
4.1 PCM-DAC08 CONNECTOR
Shown here is a PCM-DAC08 case looking into the connector which connect a signal
cable or screw terminal box and cable to. The KEY helps to insure that the cable is
inserted in the correct orientation.
10
Devices to be controlled should be connected with the high side to the numbered analog output and the low side to the analog ground.
Digital signals should not be grounded to the analog ground. Use the digital ground
or the cable shield.
4.2 CONNECTING DEVICES TO THE ANALOG OUTPUTS
The PCM-DAC08 analog outputs are single ended. There is an analog ground for
each analog output channel. When connecting multiple channels you must be sure
that pin 1 is the gro und for channel 0 , pin 2 and that pin 3 i s the gro und for channel 1,
pin 4. Also, there should be no measurable potential between the grounds at pins 1, 3
7 and chassis ground.
In addition to avoiding potentials between signal grounds, you must also avoid potentials bewteen signal ground and chassis gro und on your computer. If you are using a
laptop and are on battery power, the computer is floating with respect to earth ground,
but the laptop is on the charger unit or on wall power, the laptop may be grounded.
Whenever the computer is grounded, you must connect signals so there is no potential
between PC ground and signal ground. If there is a potential, it will be added to the
signal. For example, if your PCM-DAC08 is supplying 3.5 volts and there is a potential of -1.5V between the PC and the sensor ground, your device under control will be
reading 2.0V instead of 3.5V
4.3 OUTPUT VOLTAGE RANGES
There is one possible output voltage range of ±5V.
4.4 SIGNAL CONNECTION
The outputs of the PCM-DAC08 are two wire voltage. There is a polarity associated
with the two wires and thus the outputs are labled Analog Out Channel # and Ground,
on the connector.
The maximum current supplied by the analog outputs is 2.5mA. Therefore the minimum res istanc e, or ma ximum loa d which th e outp ut may driv e is 2K O hms. Loa ds
greater than 2K Ohms will cause the analog output to droop, meaning that a code of
4095 will not be able to generate a voltage of 5V, but one somewhat less.
11
It is best to group the ground on pin 17 with the analog output on pin 18, and the
ground on pin 19 with the analog output on pin 20, and so on.
4.5 EXTERNAL INTERRUPT INPUT
The PCM-DAC08 pin 2 is the input to a circuit which will generate an interrupt to the
computer. The inte rr up t must be enabl ed thr ough so ftware . T he inter r upt is level sensitive and is triggered on a TTL high level. TT L high is approximately 2.5V to 5V.
The interrupt signal you provide should transition from a low of o, or ground, to a
high of 5V.
The procedure initiated by an interrupt is wholly dependent on programming. Refer
to the manual for UniversalLibrary, for programmers, or Labtech or other packaged
application. UniversalLibrary provides routines for analog output as well as digital
I/O upon the detection of an interrupt.
4.6 DIGITAL INPUTS & OUTPUTS
The PCM-DAC08 has 8 bi-directional digital I/O lines. The 8 digital lines may be
programmed as input or output in groups of: 8 inputs, 8 outputs or 4 inputs & 4 outpts.
A register controls the direction of the digital I/O lines and must be set via software.
At power on or reset the digital lines default to inputs.
Please note: Digital lines in an input state present a high impedance to any device
connected to them. The implication is that if you are using a digital line to control the
input of a TTL chip, and that digital line turns from an output to an input, the T TL
chip being controlled MAY detect the turned around line as a 1 or a 0. This could
cause the TTL input being controlled to switch on or off, possibly with consequences
for the system you are controlling. To prevent random switching and force all digital
lines into a known state on power up or reset, use pull up or pull down resistors to fix
the state of the line as either high or low. A properly selected resistor will not interfere with TTL level output signals.
For more information on programming the digital I/O lines, please refer to the UniversalLibrary programmers manual..
12
5 PROGRAMMING & APPLICATIONS
Your PCM-DAC08 is now installed and ready for use.
5.1 PROGRAMMING LANGUAGES
UniversalLibrary provides complete access to the PCM-DAC08 functions from a
range of pr ogrammaing languages; both DO S and Windows. If you ar e planning to
write programs, or would like to run the example programs for Visual Basic or any
other language, please turn now to the UniversalLibrary manual.
5.2 PACKAGED APPLICATIONS PROGRAMS
Many packaged application programs, such as Labtech Notebook and DaisyLab are
designed to operate with the CIO-DAC02 and similar boards. The control software
which controls the CIO-DAC02 is not capable of controling the PCM-DAC08. The
register set for the PCM-DAC08 is not compatible with the CIO-DAC02. You will
need drivers designed for the PCM-DAC08.
Drivers for the PCM-DAC08 for LabTech, DaisyLab and other applications may have
become available since this manual was written. Call your software manufacturer, or
ComputerBoards to find out.
13
6 CALIBRATION
The PCM-DAC08 is software calibrated and tested at the factory. All calibration after
initial manufacturing is done via software. The calibration factors are stored on the
PCM-DAC08 and applied every time the board is run. The case may not be opened
and there are no parts inside which you can service. There are no socketed
components.
6.1 SOFTWARE CALIBRATION
If you are using the UniversalLibrary, you can set software calibration factors for offset and gain using the Calibration option of InstaCal. These factors will be applied to
outputs made by any of the D/A routines c alled fro m any of the language libr aries of
UniversalLibrary.
You will need a precision voltage source of better than 1/4095 resolution and that
voltage source must be calibrated.
It is important to note that once calibration factors have been set, they are stored in the
PCM-DAC08. These calibration factors are accessed by UniversalLibrary and InstaCal and applied to any output codes sent to the PCM-DAC08. If you use direct register programming be sure to access and apply the calibration factors. Of course, the
calibration factors may be reset at any time by runing InstaCal calibration.
Choose Calibration from the InstaCal menu, and follow the instructions. Press F1 for
help.
14
7 I/O ADDRESS MAP & REGISTER FUNCTIONS
A base address register controls the beginning, or 'Base Address' of the I/O addresses
occupied by the control registers of the PCM-DAC08. In all, 5 addresses are occupied. Once the CSS is installed, the base address may be modified by runing the
InstaCal program. The base address assigned by InstaCal is stored in the CB.CBG file
and read by the CSS installed in your computer. Please read about installing and
using InstaCal.
7.1 CONTROL REGISTERS
Once CSS is installed and a base address has been established, the PCM-DAC08 may
be controlled by writing to and reading from the control registers. While it is possible
to write you own control routines for the PCM-DAC08, routines have been written
and are avai lab le in Uni ver salLib r ar y for DOS a nd Wi ndo ws p ro gr amming languages.
NOTE ON REGISTER PROGRAMMING SUPPORT
While the complete register map is explained here, only very limited support for
assembly language or d ir ec t r egi ster p ro gr amming is avail ab le . I f you have a que stio n
regarding dir ec t r egist er pr o gra mming, you must FAX it. T he e nginee r ing d ep ar tment
does not accept techinical support calls but will answer faxes.
The ASSEMBLY source code to the Universal Library is not available. Information
on writing interrupt service routines and other programming tasks related to the personal computer or PCMCIA slots is not available. We support the use of the PCMDAC08 through high level languages using UniversalLibrary and the example programs provided. If there is an extension to the UniversalLibrary that would be of use
to you, please FAX your request to the attention of Software Engineering.
7.2 CONTROL REGISTERS ARE 8 BITS
All I/O access may be performed as bytes or words. Eight bit addressing is controlled
by the CSS, which is currently set for 8 bit addressing as supplied by
ComputerBoards. The registers are presented in 8 bit format here.
BASE + 0 - DAC0 LSB Data Register
Any read to this register will trigger an D/A conversion. This is a good method of
starting conversions from software or time of day clock control.
15
WRITE: D/A Data can be written to this address and to Base + 1 to form a 12 bit D/A
data word. All 8 DAC’s are updated using this register. The DAC being updated is
set via the Select bits (S3 to S0) in the Base +2 register.

Note that DACs are always updated in pairs. For example, if you latch new data to
DAC1, then update the DAC0 and DAC1 pair, DAC1 updates with the new value and
DAC0 updates with the same value as before since the latch (data for output) has not
changed.
CLR: Setting the CLR bit to 1 resets all 8 DACs output to 0V. Default and normal
operation is CLR=0, which has no effect on the DAC outputs.
