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.

PC-CARD-D24/CTR3 User's Guide Installing the PC-CARD-D24/CTR3

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:

Phone: 508-946-5100 and follow the instructions for reaching Tech Support.

Fax: 508-946-9500 to the attention of Tech Support

Email: techsupport@mccdaq.com

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 helps to insure that the cable is

inserted in the correct orientation.

You do not have to turn the computer off. The system is designed for power-on installation. You should

hear an insertion beep when you insert the card.

Figure 2. End view of the 50-pin PC-CARD connector showing proper orientation

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."

If your PCMCIA card is not detected

If the card is not detected by Windows, and you are not prompted for a driver after inserting the card, check

that your computer's 32-bit PCMCIA drivers are installed and enabled. Do the following:

From your desktop, right-click on My Computer and select Properties. The System Properties dialog

opens.

Select the Hardware tab and click on the Device Manager button.

PC-CARD-D24/CTR3 User's Guide Installing the PC-CARD-D24/CTR3

Verify that "PCMCIA adapters" is listed in the Device Manager. If you don’t find this entry, or if the

properties for the adapter indicate "this device is not working," you need to install or update your PCMCIA

adapter drivers.

If the PCMCIA adapter is not listed, use the Add New Hardware Wizard to install PCMCIA support.

If the PCMCIA adapter is listed but not working, use the Update Driver option to install the

appropriate drivers.

After performing the update procedure, reboot your PC and insert your card again.
