The Client Driver or Enabler sets the IRQ, Communication Port/Socket # (if more than one PCMCIA
socket is available), and an Address Range. These settings become the “default”. Depending on your
system configuration, these default settings may conflict with the IRQ, Communication Port/Socket #, and
Address Range that your system has already allocated to another device. If this is the case or you would
like more control of your software configuration, perform the following steps:

1.

Choose between the Client Driver
(CDQ_CL.SYS) or Enabler
(CDQ_EN.EXE) files for the one that
best suits your needs. The choice
depends on the computer environment
and the desire for plug-and-play
functionality. The table describes the
differences between the Client Driver
and the Enabler. Generally, with Card
and Socket Services, use the Client
Driver. Without Card and Socket Services, you must use the Enabler. The Client Driver is preferred
because Card and Socket Services provide better overall system management for all sockets, adapters
and cards present in the host computer (however, Card and Socket Services can limit your flexibility).
The Client Driver allows the insertion/removal of the card at any time for plug-and-play (except
during an acquisition session). The Enabler, however, requires the card be present at boot time for
proper operation.

2.

If you choose the Client Driver file option, you will need to update your CONFIG.SYS file by adding
the following command line: DEVICE=path\CDQ_CL.SYS options.

3.

If you choose the Enabler File option, you must update your AUTOEXEC.BAT file with the
command line: path\CDQ_EN.EXE options. Refer to the end of this chapter for more details.

The next 2 sections describe the details for the Client Driver and the Enabler.

Client Driver

The client driver should be installed if Card and Socket Services are installed on the host computer. As
mentioned earlier, the Client Driver allows for plug and play operation and registration with Card and
Socket Services. This registration allows Card and Socket Services to more easily manage the resources
(especially important for systems with other adapters installed). So, if possible, use the Client Driver rather
than the Enabler.

Note: If Card and Socket Services are not installed, you must use the Enabler.

To install the Client Driver perform the following:

1.

Using a text editor, edit the system’s CONFIG.SYS file.

2.

In CONFIG.SYS, place the following entry after the line(s) that install the Card and Socket Services
software: DEVICE=path\CDQ_CL.SYS options

Where path is the drive and path of the Client Driver and options are the command line options (to be
discussed later).

3.

Exit and save the CONFIG.SYS file.

4.

Insert the Daq PC-Card into one of the PCMCIA slots

5.

Reboot the host computer.

When the system comes up, the Client Driver should be loaded and a listing of the configuration options
should be displayed. If “Card and Socket Services Not Found” appears, then check to insure the card and
socket services was properly installed. If the message “Invalid Command Line Option” appears, then an
incorrect or ill-formed option was specified. Refer to the following section for the correct option syntax. If
the Daq PC-Card is configured correctly, the driver message will appear with the base address and interrupt
parameters that were assigned to the Daq PC-Card. Take note of parameters for use with the software. If,
after this, you are still having problems, use the Enabler.

The Client Driver is loaded by the system’s CONFIG.SYS file with the following format: DEVICE=install
path\
CDQ_CL.SYS options; where path is the drive and path that the Client Driver is located, and where
options are the options for which the PCMCIA interface will be configured. This section describes those
options and how to use them. The table lists the options available to the Client Driver.
