1 INTRODUCTION

CIO-DAS16/M1/16 sets the standard for high speed, 16-bit data acquisition boards for ISA bus compatible computers. The board provides 8 fully differ2ential input channels with a variety of software programmable input ranges. The board will transfer a full 1 million samples per 2second to ComputerBoards’ MEGA-FIFO memory board, and directly over the ISA bus when used in high speed (200 MHz+) pentium computers.

The board supports a variety of trigger modes. Triggers may be edge based on falling/rising or high/low states. The board also provides 32-bits of digital I/O (24-bits CMOS, 8-bits TTL). 2

The CIO-DAS16/M1/16 is fully supported by Universal Library® package which supplies a language interface for all Windows and DOS based programming languages. The board includes helpful InstaCal® installation, test and calibration software package. The CIO-DAS16/M1/16 is also supported by a wide variety of third party data acquisition and analysis software packages.

2 QUICK START

The installation and operation of CIO-DAS16/M1/16 is very straightforward. This quick start procedure will help you quickly and easily setup, install and test your board. We assume you already know how to open the PC and install expansion boards. If you are unfamiliar or uncomfortable with board installation, please refer to your computer’s documentation.

We recommend you perform the software installation described in sections 2.1 and 2.2 below prior to installing the board in your computer. The InstaC

operations below will show you how to properly set the switches on the board prior to p hysically installing

the board in your computer.

2.1 INSTALL THE INSTACALTM SOFTWARE

Windows (in its various forms) and DOS users install the program by running the Install.exe (some versions of the software will also have a file named Setup.exe. If your disk contains this file, please run it rather than Install.exe) program supplied on the disk you received labeled Insta run install and follow the on-screen instructions. The default location of the installed files is on your main hard drive in a directory or folder named C:\CB\. However at installation time, you have the option to select a different drive or directory name.

2.2 RUN INSTACAL

To run Insta click your mouse on it. In DOS simply type instacal and press the Enter key.

Once running, Insta

Select

Install

Select

Board #0

Cal

(either highlight it and hit enter or double click your mouse on it).

(select another number if Board #0 is already installed)

. It will create all required folders/directories and unpack the various pieces of compressed software. Simply

Cal

in the various forms of Wind ows, find the file named InstaCal. exe using your file management system and double

provides four sub-menus (plus exit).

Cal

Select

Board Type

Move through the selections and highlight the particular board you are installing (e.g. CIO-DAS16/M1/16) Either double click on the board or hit enter. The board’s default settings are then displayed. The board’s defaults are:

Base Address (hex): 300 Interrupt Level: 5 Ext Memory Board: Not Connected Counter Source: External

The program will also show you how to set the onboard base address switch. If this is the first installation, we recommend you keep the board set at it’s factory default configuration unless you have a specific consideration that forces you to make a change.

You are now ready to install the board in your computer. Turn off and unplug your computer. It is now safe to open your PC and install the board. After the board is installed and the computer is closed up, turn the power back on.

Run InstaCalTM again, and at the main menu select Test.

Select the board you just installed

Select Input, and then CH 0

Select Source, and then DIO 1

Select Plot, the required connections to complete the test will then be shown on your computer screen. Either use the jumper wires provided with the board to make the connections directly on the board’s I/O connector, or make the connection with a jumper wire on your Screw Terminal Adapter board.

Once you have connected the digital I/O output to the A/D input, proceed and plot the waveform. You should observe a square wave. If you do, your board is installed and working properly. If not we suggest the following.

1. Make certain you have connected the correct pins according to the connector diagram.

2. Go back through the installation procedure and make sure you have installed the board according to the instructions.

3. Go back through the installation procedure and select an alternate base address.

If this does not get you to the squarewave display, please call us (or contact your local distributor) for additional assistance.

3 INSTALLATION & CONFIGURATION

The CIO-DAS16/M1/16 has only one switch to set prior to installing the board in your computer. By far the simplest way to configure your board is to use the Insta

program included with your board. Insta

Cal

will show you all available options, how to config-

Cal

ure the various switches and jumpers to match your application requirements, and will create a configuration file that your application software (and the Universal Library) will refer to so the software you use will automatically know the exact configuration of the board.

Please refer to Chapter 1 regarding the installation and operation of Insta

. The following hard copy information is provided as a

Cal

matter of completeness, and will allow you to set the hardware configuration of the CIO-DAS16/M1/16 board if you do not have

immediate access to Insta

and/or your computer.

3.1 BASE ADDRESS

Unless there is already a board in your system using address 300 HEX (768 Decimal), you can leave the switches as they are set at the factory.

In the example shown below, the CIO-DAS16/M1/16 is set at base address 300H.

9876

4 SIGNAL CONNECTIONS

There are two co nnecto rs on t he CI O-DAS16 /M1/ 16. T he 37 pi n conne ctor which extend s thro ugh the mounting p late and extend s out the rear of the PC is primarily for analog signals, and is called the analog connector. The 40 pin header connector at the rear of the board carries the 24 digital I/O and is called AUX DIO connector.

4.1 ANALOG CONNECTOR DIAGRAM

The CIO-DAS16/M1/16 analog connector is a 37 pin D type connector accessible from the rear of the PC through the expansion backplate. With the exception of the missing D/A signals, the signals available are identical to the CIO-DAS16. The connector accepts female 37 D type connectors, such as those on the C73FF-2, 2 foot cable with connectors. If frequent changes to signal connections or signal conditioning is required, please refer to the information on the CIO-TERMINAL or CIO-MINI37 screw terminal boards.
