Chapter 1

Introducing the PC-CARD-D24/CTR3

Overview: PC-CARD-D24/CTR3 features

The PC-CARD-D24/CTR3 is a data acquisition and control board for IBM PC compatible computers with
PCMCIA/PC-CARD type slots. The primary functional elements consist of the following:

 An 82C55 chip using TTL logic for 24 bi-directional digital I/O channels.
 An 82C54 counter/timer chip that has three, 16-bit down-counters.

Under software control, the counters can be clocked internally from a 10 or 1 MHz crystal oscillator,
clocked externally, or chained to yield a 32- or 48-bit counter. Each counter can be gated (disabled) with
an external gate signal

The 24 digital I/O channels are divided into three ports — A, B, and C. Each port has eight I/O channels. At
power-on or reset, the digital lines are set as inputs. The board provides three independently programmable and
functioning 16-bit down-counters. You can access the clock input, gate, and output for each counter.

Unpacking the PC-CARD-D24/CTR3

As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the PC-CARD-D24/CTR3 from its packaging, ground yourself using a wrist strap
or by simply touching the computer chassis or other grounded object to eliminate any stored static charge.

If any components are missing or damaged, notify Measurement Computing Corporation immediately by
phone, fax, or e-mail:

Installing the software

Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing Data
Acquisition Software CD. This booklet is available in PDF at www.mccdaq.com/PDFs/manuals/DAQ-

Software-Quick-Start.pdf.

Installing the PC-CARD-D24/CTR3

The PC-CARD-D24/CTR3 board is completely plug-and-play. There are no switches or jumpers to set. To
install your board, follow the steps below.

Install the MCC DAQ software before you install your board

The driver needed to run your board is installed with the MCC DAQ software. Therefore, you need to install
the MCC DAQ software before you install your board. Refer to the Quick Start Guide for instructions on
installing the software.

To install your PC-Card, do the following:
 Insert the card into a free PC Card/PCMCIA type II or III slot. The key

You do not

hear an insertion beep when you insert the card.

Windows automatically detects, recognizes, and configures the PC-CARD. You should hear an insertion beep
when you insert the card into the slot. To verify that the card is recognized, go to Control Panel\System\Device
Manager and the card should now appear under "DAS Component."

Programming and Developing Applications

After following the installation instructions in Chapter 2, your board should now be installed and ready for use.
In general there may be no correspondence among registers for different boards. Software written at the
register-level for other models does not function correctly with your board.

Programming languages

Packaged applications programs

Many packaged application programs now have drivers for your board. If the package you own does not have
drivers for the board, please fax or e-mail the package name and the revision number from the install disks. We
will research the package for you and advise how to obtain drivers.

Some application drivers are included with the Universal Library package, but not with the application package.
If you have purchased an application package directly from the software vendor, you may need to purchase our
Universal Library and drivers. Please contact us by phone, fax or e-mail:
