• Serial A/D measurement module incl. D/A converter
• 4 A/D channels (12 Bit resolution using differential-ended Modus) or
• 8 A/D channels (11 Bit resolution using singel-ended Modus)
• 2 D/A channels (10 Bit resolution)
• 24 TTL I/O
• 2x 32Bit Counter with max. 1MHz Input Frequency

Through the RS232 port on the module it is now possible to make AD/DA measurements and TTL I/O controlling by using the serial RS232 interface.

The SERAD8DAC2 is a further developement of the proven USB-AD8DAC2. Through the upgraded serial RS232-Port it is now possible to easily make AD/DA measurements also when using older operating system like DOS. Certainly it is also possible to use this module with any other system which supports RS232 communication.

Please notice that an external 5V power supply is needed to use this module independedly.

This professional serial AD/DA module provides up to 8 AD channels and 2 DA channels, which are capable to convert signals with up to 14 bit.
The SERAD8DAC2 also has 24 TTL I/O channels, and two 32 bit counters onboard. The counter has a maximum frequency of 1MHz. Both, TTL I/O and counters are easily accessible through the 37 pole female D-SUB connector.

A/D Modes
Using the SERAD8DAC2 two A/D modes are provided.

Differential ended mode with 4 A/D channels and a 12 Bit resolution
Single ended mode with 8 A/D channels an a 11 Bit resolution

The mode may be easily changed by supported driver functions.

Analog-To-Digital-Conversion
The SERAD8DAC2 needs 20µs coversion time in differential ended mode by using one of the following measurementranges: +/- 20V, +/- 10V,+/- 5V, +/- 4V, +/- 2,5V, +/- 2V, +/- 1,25V, +/- 1V.

Sindle ended mode uses a measurement range of +/-0..10V by using the same conversion time.

Digital-To-Analog-Conversion
The 2 D/A outputs provide a 10 Bit resolution with a voltage range of +0..5V and may be charged with up to 10mA.

Softwaresupport
Through implementation of this module into the QLIB (QUANCOM Driver Library) no knowledge in driver programming is needed and an easy to use programming API for Windows 95-Vista is provided. By using the QLIB it is easy and fast to develop applications using modern comilers like Delphi, Visual Basic, Visual Basic.NET, Visual-C, C#, C/C++ or graphical IDE i.e. Agilent VEE and LabView. Sample projects for the most languages are located on the driver CD and on this website.
