Data Acquisition System (USB) Measurement & Control. Super-Low Priced. Record and output signals with the USB-AD14f. The USB data acquisition system accomodated in a stable aluminum housing is ideal for medium-class applications impressing by universal applicability and an excellent price-performance-ratio. 16 Analog Inputs. 20kHz. 14 Bit. ±10V. Voltage signals in the ±10V range are connected at 16 analog inputs. Sampling is done with 14 bit resolution and 20kHz total sampling rate. 1 Analog Output. 12 Bit. ±5V. The 5 V output can be used for analog control with 12 bit accuracy. 8 Digital IN. 8 Digital OUT. 1 Counter. Digital states are recorded or set at eight digital inputs and outputs each. Digital inputs are sampled time-synchronously with the analog inputs. The USB-AD14f features a 16-bit counter for the acquisition of counting pulses. Plug & Play. The connection to the PC is realized via USB. The USB-AD14f 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® XP/7/8/10 as well as under Mac OS X, Free BSD, and Linux. The complete software for installation and programming of the USB-AD14f is included for free. NextView®4. Try for Free. The DAQ system is supported by NextView® 4, 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-AD14f. 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 acquisition system. bavarian measurement company munich

1 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). The device is supplied with power via the USB-connection. If necessary, further software components can be installed now, as described in chapter 5. O Ain = Analogeingang / analog input # AOut = Analogausgang / analog output O AGND = analoge Masse /...

3 Digital Inputs and Outputs The USB-AD14f features 4 digital inputs and outputs each (low: 0V..0.7V; high: 3V..5V). A 16-bit counter is available at pin 9. All connections are led to the 25-pin D-Sub female connector on the back of the device. The pin assignment is as follows: # DOut = Digitalausgang / digital output O DGND = dlgltale Masse / digital ground ® n. c. = nicht verbunden / not connected O Din = Digitaleingang / digital input Counter = Zahlereingang / counter input • The digital lines are protected by resistors. If the input voltage is not within the permitted voltage range of...

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 3.9kQ pull-down resistor is absolutely necessary to create a defined low signal! 4.1.3 Connecting a Voltage Divider If connecting a DC voltage higher than 5 V, a voltage divider must be used so that 5V at the maximum are applied at the device input. Exceeding the 5V input voltage might cause damages to the device. The relation between the two resistors to be used is calculated with the following formula: U/U1= (R1+R2)/R1 Input...

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. Please also observe the total current listed in the technical data (see chapter 7). 4.2.2 Connecting a Relay A connected relay is ideal to switch higher currents. Since the field coil of the relay requires a higher current than provided by the measurement system at one line, a transistor is connected ahead. O Relay cards featuring 8...

5 Software Installation All software and documentation available for the USB-AD14f are integrated on the "Software 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-AD14f by selecting the entry "Products" in the CD starter and then the hardware ("USB-AD14f') listed under the interface "USB". For detailed information about installing or operating the software, please see the corresponding manuals. The Adobe Acrobat Reader is required to open the documentation in PDF format. You...

Plug&Play Installation As soon as the device 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® 7/8/10. Under Windows® XP, the automatic hardware detection is started by selecting the following: - Windows® 7/8/10: no specifications required - Windows® XP: "Install the software automatically" (SP2: do not connect with Windows® Update!) 5.1.3 Check Installation The entry "Data Acquisition (BMC Messsysteme GmbH)" is included in the Windows® Device Manager after...

6 Important Notes for Using the USB-AD14f • The device is only suitable for extra-low voltages - please observe the relevant regulations! Only use the device with housing closed. ESD voltages at open lines may cause malfunction. • Only use non-solvent detergents for cleaning. The product is designed to be maintenance-free. • Signal cables are connected at the 37-pin or 25-pin D-Sub female connector - preferably use shielded cables. For best possible interference suppression, connect shield at one end only. Close open inputs if necessary. • The device ground and the chassis are electrically...
