1.0 Introduction

1.1 Software Installation

Insert the CD ROM included with your OME-PCI-1202 board and the following

installation screen should auto-start.

Follow the instructions on the screen to complete the software installation. The

software is designed to support the entire OME family of data acquisition hardware, so

during the installation, you will be asked to specify your particular hardware (OME-

PCI-1202 board in this case). During the installation process, you will also be

prompted to enter the operating system you will be using.

After installation the following folders will be created on your computer.

5

Demo Folder
Contains all demonstration programs including their source code. Examples are
provided for Visual C++, Borland C++, Visual Basic and Delphi.
Please note: The VC++ demos are developed with VC++ 4.0. After setting up the
environment, use NMAKE.EXE to compile and link the demo code. For example,
C:\P1202\DEMO\VC\nmake /f demo1.mak

Driver Folder

Contains software drivers, include files and definition files for programming
languages.

Manual Folder

Contains hardware user manuals, software user manuals and technical notes.

Diag Folder

Contains card diagnostic programs

Inf Folder

Contains tech notes and .INF file for the plug and play installation (only available for
operating systems that support plug and play).

6

1.2 Plug & Play Installation for

Windows

The 1202.inf file provides all the information needed to complete the Plug & Play

installation. After the installation, Windows will reserve the resources and update the

registry. The Plug & Play information is shown in Fig 1(Windows 2000 device manager).

Figure 2 shows the resources reserved. If the user runs “c:\WINNT\regedit.exe”, the registry

information of the OME-PCI-1202H/L can be found under

“HKEY_LOCAL_MACHINE\System\CurrentControlSet001\Services\P1202” as in Fig 3.

The Fig 4 shows the registry items in detail.

1.3 Using With Visual C++

All the demo programs have been developed and tested using Windows 95/NT

and Visual C++ 4.0 compiler. The key points are given as below:

1. Make sure the PATH includes the Visual C++ compiler

2. Execute the \MSDEV\BIN\VCVARS32.BAT to setup the environment. The

VCVARS32.BAT is provided in Visual C++.

3. The source program must include “P1202.H”

4. Copy the P1202.LIB, import library, to the same directory as the source program.

5. Copy the P1202.DLL, to the same directory as the source program

6. Edit the source program (e.g. DEMO1.C)

7. Edit the NMAKE file (e.g. DEMO1.MAK)

8. NMAKE /f DEMO1.MAK

9. Execute DEMO1.EXE

NOTE: The P1202.lib is used at linking time and the P1202.DLL is at run time.

1.4 Using With MFC

The key points for using MFC are given as below:

1. Use MFC wizard to create source code

2. The source program must include “P1202.H”

3. Copy the P1202.LIB, import library, to the same directory as the source program

4. Copy the P1202.DLL, to the same directory as the source program

5. Select Build/Settings/Link and key “P1202.lib” in the object/library

modules field

NOTE: The P1202.lib is used at linking time and the P1202.DLL is used at run

time.

10

1.5 Using With BC++

The drivers were created with Visual C++ 4.0. The P1202.H and P1202.lib are

also directly compatible with Visual C/C++. You cannot use these files with BC++.

The following modifications are required:

#include <conio.h>

#include <windows.h>

HINSTANCE hDLLLib;

// Step 1 : declare a function pointer

float CALLBACK (*FloatSub2)(float fA, float fB);

main()

{

// Step 2 : load dll

hDllLib=LoadLibrary("P1202.dll");

if (hDLLLib)

{

// Step 3 : get the function address

FloatSub2=(FARPROC)GetProcAddress(hDLLLib,"P1202_FloatSub2");

if (FloatSub2)

{

// Step 4 : call function

printf("1.2-3.4=%f",FloatSub2(1.2,3.4);

}

else printf("get P1202_FloatSub2 function address error");

// Step 5 : free library

FreeLibrary(hDLLib);

}

else printf("load P1202.dll error");

getch();

}

By incorporating these modifications and the P1202.DLL, the user can use

BC++ to call the driver.

NOTE:

1. Tested under Windows 95/NT and LabVIEW 4.0

2. The demo1.VI will call MFUN1.VI to perform M_Functions. The M_Functions

can send an arbitrary waveform to the D/A output and perform A/D input at the

same time. If D/A channel_0 is connected to A/D channel_0, M_Functions can

measure the D/A output back. The output response is shown in Fig 8 and the

connection diagram for demo1.VI is given in Fig. 9.

process could be disturbed by operating system interrupts. Since the hardware pacer is

used to control the A/D process in the P1202_AdsPacer function, it is a better choice if a
waveform must be precisely reconstructed. This function will refer to the current active

OME-PCI-1202 board. Use the P1202_ActiveBoard(….) to select the active board.
