OME-A-826PG Software Manual [Win 95/98/NT]

1 Introduction

The OME-A-826PG is a multifunction, 16 bits resolution A/D, D/A and digital

I/O card. The feature of the OME-A-826PG are given as below:

1. A/D=16 bits, 16 channels(single-ended) or 8 channels(differential)

2. A-826PG : low gain (1/2/4/8), the analog input signal range configuration code is given in
Sec. 4.1

3. DA=12 bits, 2 channels, 0-5V or 0-10V output by hardware JP1 setting

4. 16 channels TTL compatible digital input

5. 16 channels TTL compatible digital output

The A826.DLL and A826.Vxd is a collection of data acquisition subroutines
for the OME-A-826PG Windows 95/98 Applications. These subroutines are
written with C language and perform a variety of data acquisition operations.

The subroutines in A826.DLL are easy understanding as its name standing
for. It provides powerful, easy-to-use subroutine for developing your data
acquisition application. Your program can call this DLL functions by VC++, VB ,
Delphi , Borland C++ Builder easily. To speed-up your developing process, some
demonstration source program are provided.

The OME-A-826PG consists of these DLLs and device driver :

For Windows 95/98

• A826.dll, A826.lib ÆLibraries for A826 PG card

• A826.Vxd Æ A826 Device driver for Windows 95/98

For Windows NT

• A826.dll, A826.lib ÆLibraries for OME-A826 PGL/PGH card

• A826.sys, Napwnt.sys ÆA826 Device driver for Windows NT

These DLLs can perform a variety of data acquisition operations as follows:

1.2 Range Configuration Code

The AD converter of the OME-A-826PG is 16 bits under all

configuration code. If the analog input range is configured to ±5V range, the

resolution of one bit is equal to 2.44 mV. If the analog input range is configured to
±2.5V range, the resolution will be 1.22 mV. If the analog input signal is about
1 V, use configuration 0/1/2 (for OME-A-826PG), it will get nearly the same result

except resolution. So choose the correct configuration code can achieve
the most high precision measurement.
