The DAQP series card is a PCMCIA type II data acquisition system with 8 differential or 16
single-ended analog input channels. The number of input channels can be expanded to 256
with an i nput e x pansi on card. DAQP series pr od ucts include the DAQP-12, the DAQP-16 and
the high gain DAQP-12H. The programmable gain settings of the DAQP-12 and DAQP-16
span bipolar input ranges of ±1.25 V (gain = 8), ±2. 5 V (gain = 4), ±5 V (gain = 2) and ± 10V
(gain = 1), w hile the DAQP-12H offers a bipol ar input range of ±0.01 V (gain = 1000), ±0.1 V
(gain = 100), ±1 V (gain = 10) and ± 10V (gain = 1).

The DAQP card supports sampling rates up to 100 kHz with either 12 or 16-bit resolution.
Equipped with a data FIFO of 2048 samples, the DAQP card can achieve high speed data
acquisition under various operating platforms including MS-DOS®, Windows 3.xx and
Windows 95®. Also equipped with a scan FIFO of the same size, the DAQP supports full
speed, random order channel scanning and gain selection for all input channels including
expansion channels. The DAQP card uses a 24-bit pacer clock and a programmable
divide-by-2, by-10 or by-100 pre-scaler. The pacer clock can also be used with either an
internal or external cl ock source. With the 10 MH z internal clock source, the pacer clock can
generate accurate sampling rates from 0.006 Hz to 100 kHz. The DAQP card has 4 digital
input and output channels, all TTL compatible, which may be used for process control or
monitoring in addition to analog data acquisition.

2. Installation

DAQP-12/12H/16 Users Manual 10

2.1 Hardware Setup

Insert the DAQP card into any type II PCMCIA socket. All other configuration options are
determined by the operating system.

2.2 Software Setup (Windows 95/98®)

An “.INF” file (DAQPCARD.INF) is provided on the root directory of the DAQSUITE
CD-ROM for easy installati on of the DAQP series car d under Wind ows 95/98. The operating
system uses the “.INF” file to determine what system resources are required by the card,
searches for available resources to fill the requirements, configures the DAQP card hardware
and then updates the hardware registry with an entry that allocates these resources.

2.2.1 Installing the DAQP Series Card

1. Insert the DAQP card in any available PCMCIA socket.

2. The first time a new PCMCIA type card is installed the “New Hardware Found”
window opens. Windows 95/98 will automatically detect and configure the card. If
the “New Hardware Found” window does not open, skip to the next section:
“Viewing the PCMCIA Card Status”.

3. Windows will ask for the CD-ROM that came with the device. Insert the CD, click
“Next” to continue and then click “Finish”.

4. W indows automatically b rowses the root dir ectory on the CD for the IN F file that
defines configurations for the new hardware type found. The file name is not
required. After searching the root directory, Windows will choose the correct file.

5. Your new PCMCIA card should now be configured. In the future, Windows will
automatically recognize and configure this specific PCMCIA card type.

2.2.2 Viewing the DAQP Series Card Status

1. Double click the “My Computer” icon located on the Windows 95/98 desktop. This
opens a folder showing the various drives, printers, etc. (This can also be done by

2.

Inside the “Control Panel” fold er, double cli ck the “System” icon so that the “System
Properties” window opens. Select the “Device Manager” tab. Find the entry titled
“Data_Acquisition” on the device list. Expand the entry by clicking the leading “+”
sign or by double clicking the name.

3.

From the expa nded sub-list, choose the DAQP card to reconfigure (ther e may be only
one entry) by double clicking it.

4.

Select the “Resources” tab from the pop-up window. Click the resource type (either
“Input/Output range” or “Interrupt Request”) from the “Resource Setting” table and
then click the “Change Settings ...” button. This opens the “Edit Input/Output Range”
or “ Edit Interrupt Request” window.

5.

Change the value by clicking on the slider controls by the “value” list and then click
OK to confirm the change, or CANCEL to discard it. Watch for possible conflicts
shown in the “Conflict Information” box.

The only conf iguration parameters that can be changed for the DAQP car d under Windows
95/98 are “Input/Output Ranges” and “Interrupt Request”.

DAQP-12/12H/16 Users Manual 13

3.1

For systems using MS-DOS and PCMCIA Card and Socket Services software, a Client Driver
named “DAQP_CL.SYS” i s provided to confi gure the DAQP series card s. PCMCIA Card and
Socket Services software is not provided and must be purchased independently.

Some versions of Card and Socket Services dated b efore 1993 do not support general purpose
I/O cards. After careful installation of the Client Driver, if the DAQP card still does not
configure or operate properly, an updated version of Card and Socket Services software may
be required. The following procedures are used to install the DAQP series Client Driver:

Installing the Client Driver

1. Copy the file DAQP_CL.SYS located in the PCMCIA\DOS\CLIENTS directory of the
“DAQSUITE” CD-ROM onto the root directory of the system hard drive.

2. Using an ASCII text editor, open the system CONFIG.SYS file located in the root
directory of the boot drive.

3. Locate the line in the CONFIG.SYS file where the Card and Socket Services software is
installed.

4. AFTER the line installing the Card and Socket Services software, add the following line
to the CONFIG.SYS file:

DEVICE = drive:\path\DAQP_CL.SYS options
where options ar e the DAQP series Cl ient Driver command line options discussed on

the following pages. (Path is only required if the user copies the Client Driver into a
directory other than the root directory).

5. Save the CONFIG.SYS file and exit the text editor.

6. Insert the DAQP card into one of the system PCMCIA slots.

NOTE: Since the DAQP series Client Driver supports "Hot Swapping", it is not
necessary to have the DAQP card installed when booting the system. However, by
inserting the card before booting, the Client Driver will report the card configuration
during the boot process and thereby verify changes made to the CONFIG.SYS file.

7. Reb oot the system and note the message d isplay ed when the Cli ent Dri ver is loade d. If
the Client Driver reports an “invalid command line option”, correct the entry in the
CONFIG.SYS f ile and reb oot the system. If the Client D river r eports “Card and Sock et
Services not found”, then either Card and Socket Services software must be installed on
the system or the DAQP series Enabler program must be used to configure the card,
(see Chapter 4 ). If the Client Driver reports the desired card configuration, the
installation process is complete and the DAQP card may be removed and inserted from
the system as desir ed. On each insertion into the PCMCIA socket, the DAQP card wil l
automatically be reconfigured to the specified settings.

3.2

DAQP-12/12H/16 Users Manual 14

The DAQP series Client Dri ver accepts up to eight command l ine arguments from the user to
determine the configuration of the DAQP card. If any arguments are provided, the Client
Driver will attempt to configure any DAQP card with the options specified in the order they
are entered on the command line. Each argument must be enclosed i n parenthesi s and must be
separated from other arguments by a space in the command line. Inside an argument, a
comma (no space) should b e used to separate the para meters f rom each other if there are two
or more parameters. Within each argument, any or all of the following parameters may be
specified:

(b address) Specifies the base I/O address of the DAQP card in hexadecimal.

(i irq) Specifies the interrupt level (IRQ) of the DAQP card in hexadecimal.

Client Driver Command Line Options

“Address” must be in the range 100H - 3F8H and must reside on an even 8-byte
boundary (“address” must end in 0 or 8). If this option is omitted, a base address
will be assigned by Card and Socket Services software.

“Irq” must be one of the following values: 3, 4, 5, 7, 9, 10, 11, 12, 14, 15 or 0 if no
IRQ is desired. If this option is omitted, an interrupt level will be assigned by
Card and Socket Services software.

(s socket) Specifies the PCMCIA socket number to configure.

“Socket” must be in the range 0 - 15. If this option is omitted, the configuration
argument will be applied to any DAQP card inserted into any socket(s) in the
system.

3.3 Client Driver Installation Examples

With the Client Driver, the user may specify a list of selections (in the form of command line
arguments) for the configuration of the DAQP series cards. The Client Driver scans this list
from left to right until it finds a selection that is currently available in the system. If none of
the preferred selections are available, the Client Driver requests a configuration from Card
and Socket Services software.

Example 1: DEVICE = C:\DAQP_CL.SYS
In example 1, no command line arguments are specified. The Client Driver will configure the

DAQP card into ANY socket with a base ad dress and IRQ level assigned by Card and Socket
Services.

Example 2: DEVICE = C:\DAQP_CL.SYS (b300)
In this example, a single command line argument is provided. The Client Driver will attempt

to configure a DAQP card inserted into ANY socket with a base address of 300H and an IRQ
level assigned by Card and Socket Services. If the base address 300H is not available, the
DAQP card will NOT be configured.

Example 3: DEVICE = C:\DAQP_CL.SYS (s0,b300,i5)

Example 3 is also a single command line argument. The Client Driver will attempt to

DAQP-12/12H/16 Users Manual 15

configure the DAQP card inserted in socket 0 at base address 300H and IRQ level 5. If either
address 300H or IRQ 5 are unavailable, the card will NOT be configured. In addition, the
Client Driver will NOT configure any DAQP card unless inserted into socket 0.

Example 4: DEVICE = C:\DAQP_CL.SYS (b300,i5) (i10) ( )
Three command line arguments are provided in this example. The Client Driver will first

attempt to configure a DAQP card inserted into any socket wi th a base address 300H and IRQ
level 5. If either address 300H or IRQ 5 are unavailable, the Client Driver will proceed to the
second command line argument and attempt to configure the card with a base address
assigned by the Card and Socket Services and IRQ level 10. If IRQ 10 is also unavailable, the
Client Driver will then go to the third command line argument and attempt to configure it
with a base address and an IRQ level assigned by Card and Socket Services.

Example 5: DEVICE = C:\DAQP_CL.SYS (b300,i5) ( ) (i10)
The difference between examples 5 and 4 is the order of the second and third command line

arguments. The Client Driver will first attempt to configure a DAQP card inserted into any
socket with a base address 300H and IRQ level 5. If either address 300H or IRQ 5 are
unavailable, the Client Driver will proceed to the second command line argument and attempt
to configure the card with a base address and IRQ level assigned by Card and Socket Services.
Since the second command line argument includes all available address and IRQ resources,
the third command line argument will never be reached. The user must ensure the command
line arguments are placed in a logical order.

Example 6: DEVICE = C:\DAQP_CL.SYS (s0,b300,i5) (s1,b310,i10)
There are two command line arguments in example 6, which is desirable in systems where

two or more DAQP cards are to be installed. The Client Driver will attempt to configure the
DAQP card in socket 0 with base addr ess 300H and IRQ level 5. If there is a DAQP card i n
socket 1, it will be configured with base address 310H and IRQ 10. This allows the user to
force the card addresses and I RQ settings to be socket speci f i c as required by software or cable
connections. If the requested resources are not available, the DAQP cards will not be

configured.

3.4 Common Problems

3.4.1 Generic Client Drivers

Many Card and Socket Services packages include a generic client driver (or SuperClient)
which configures standard I/O devices. If one of these generic client drivers is installed, it
may configure the DAQP card and cause the DAQP series Client Driver to fail installation. If
this is the case, the operation of the generic client driver can be modified so that it will not
configure the DAQP card. Place the DAQP series Client Driver command line before the
generic client driver command line in the CONFIG.SYS file. Consult the Card and Socket
Services documentation for availability and details of this feature.
