USB-AD12f
Data acquisition system (USB)
Measurement & Control.
Super-low priced.
Record and output signals with the USB-AD12f.
The USB data acquisition system accomodated in
a stable aluminum housing is ideal for medium-
class applications impressing by universal appli-
cability and an excellent price-performance-ratio.
16 analog inputs.
20kHz. 12 bit. ±10V.
Voltage signals in the ±10V range are connected
at 16 analog inputs. Sampling is done with 12 bit
resolution and 20kHz total sampling rate.
1 analog output. 12 bit. ±5V.
The 5V output can be used for analog control
with 12 bit accuracy.
4 digital inputs/outputs each.
1 counter.
Digital states are recorded or set at four digital in-
puts and outputs each. Digital inputs are sampled
time-synchronously with the analog inputs. The
first digital input can be used as a 16-bit counter
for the acquisition of counting pulses.
Functional diagram
Plug & Play.
The connection to the PC is realized via USB.
The USB-AD12f provides all typical USB
features (e.g. Plug&Play, Hot-Plug). Up to 127
devices can be connected and installed during
operation.
Powered by USB.
The device is supplied with power via the USB
interface. This reduces cabling efforts to a
minimum and makes mobile measurements a lot
easier.
Open for everyone.
Widely supported: The data acquisition system
can be used under Windows
under MAC OS X, Free BSD and Linux. The
complete software for installation and program-
ming of the USB-AD12f is included for free.

The DAQ system is supported by NextView
the software for data acquisition and analysis. A
fully functional 30-day trial is included with
delivery to directly test the functionality of the
USB-AD12f.
Accessory.
Makes everything so easy.
Use the demo board ZU-DBD featuring various
operating controls and sensors to generate 16
analog signals and record them with the USB data
aquisition system.

  • Page 2: Start-Up Procedure

    Start-up procedure Install the bmcm driver package (see chapter 5.1.1). Plug the red frames onto the short sides of the device with the feet looking downward as to be seen in the product picture. Connect one end of the USB cable to the device and the other to the USB-interface of the PC and start the Plug&Play installation (see chapter 5.1.2).

    4 Interfacing examples for the digital lines of the USB-AD12f The following basic connection examples demonstrate the use of the digital inputs and outputs and the connection of a counter to the USB-AD12f. The pin assignment of the 15-pin D-Sub female connector is described in chapter 3.
  • Page 4 USB-AD12f 4.1.2 Connecting a push-button / switch Please make sure to use a push-button with debounce protection, because otherwise several pulses might be recorded. The 3.9kΩ pull-down resistor is absolutely necessary to create a defined low signal! 4.1.3 Connecting a voltage divider...
  • Page 5 USB-AD12f 4.2 Interfacing examples for digital outputs Serial resistors in the output lines limit the current and protect the hardware from being destroyed. 4.2.1 Connecting an LED Only so-called low-current LEDs can be used, because they already work with 1mA current.

    Collection" CD included with delivery. When inserting the CD, a CD starter opens automatically (otherwise: start openhtml.exe). Change to the product page of the USB-AD12f by selecting the entry "Products" in the CD starter and then the hardware ("USB-AD12f") listed under the interface "USB".
  • Page 7 USB-AD12f 5.1.2 Plug&Play installation As soon as the USB-AD12f is connected to the PC, the system announces the new hardware. Since the driver ® package has been copied to hard disc before, the hardware will be installed automatically under Windows ®...

    The gain is adjusted to even values. Therefore, only 4000 values (for 12 bit) of the full range of the converter are used. As a result, the measuring ranges are slightly larger (e.g. ±10.24V) than the indicated measuring ranges so that overranges can be recognized. The AD converter of the USB-AD12f has a code noise of up to ±1 LSB. •...
