LAN Data Acquisition System Data Acquisition via Network. Remote. The LAN technology of the LAN-AD16fx allows for measurement applications across great distances. The number of measuring points, where the devices are installed, is basically not limited. Data transmission to a server PC is fast and reliable. PoE. Self-Supplier. The device can be supplied with power via network (Power over Ethernet). This reduces cabling efforts to a minimum and makes mobile measurements a lot easier. TCP/IP. Guaranteed Reliable. LAN-AD16fx uses the TCP/IP protocol providing for safe and complete data transmission. Besides that, transmission via internet is possible - data acquisition with absolutely new possibilities. Cascadable. Synchronizable. The number of DAQ systems and with it the number of available channels is only limited by the bandwidth of the network. Several devices can be synchronized with each other. If so, all measured data in distributed operation always keep time even with long-term measurements. 16 Analog IN. 2 Analog OUT. 16 analog inputs can be sampled with 16 bit resolution and 250kHz total sampling rate. The measuring range (±10V, ±5V, ±2V, ±1V) is selected via software for each channel separately. The two ±10V outputs can be used for analog controls with 16 bit accuracy. 32 Digital I/O. Digital states are recorded or set at 32 digital inputs or outputs. The direction of the two 16-bit ports is set via software. Count and Measure: Pulses. Frequency. Position. Period. If for the acquisition of large quantities, speed measurement, or determination of position: These are only a few applications the three 32-bit counters of the LAN-AD16fx can be used for. With the pulse time feature, precise measuring e.g. at slowly rotating shafts is possible. 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 LAN-AD16fx 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 LAN-AD16fx. bavarian measurement company munich

Start-up Procedure Before starting the device check the safe connection between the housing and earth (see chapter 2.2). Connect the device to a PC or server via network (see chapter 2.1). The device is also supplied via network (PoE). Alternatively, LAN-AD16fx can be powered by an external supply unit (see chapter 2.2). The LAN-AD16fx self-assigns a suitable link-local address when being connected. If necessary, further software components to be used with the device can be installed now, as described in chapter 4. The PC/data acquisition server and the LAN-AD16fx communicate via LAN realized...

2.3 Analog Channels The 37-pin D-Sub female connector "Analog In/Out" at the back of the device is designed for the connection of the analog inputs and outputs. The input range (±10V, ±5V, ±2V, ±1V) is set via software (e.g. in NextView®4), the output range is ±10V. 2.3.1 Analog Pin Assignment The pin assignment of the 37-pin D-Sub female is as follows: O Ain = Analogeingang / analog input 9 AOut = Analogausgang / analog output O AGND = analoge Masse / analog ground ® n. c. = nicht verbunden / not connected The max. potentials to ground must not exceed ±12V. Any channel overload may influence...

2.4 Digital Channels and Counters The LAN-AD16fx features two digital ports with 16 inputs or outputs each. The lines are bidirectional and set in groups of eight. Additionally integrated are three counters (quadrature decoders) for pulse, frequency, position, or pulse time measurement. All lines are led to the 37-pin D-Sub female connector at the device front. The pin assignment is as follows: D-Sub 37 (Digital In/Out) • 5V Hilfsspannung / 5V auxiliary voltage O digitale Masse / digital ground O • The digital inputs and outputs are protected by serial resistors. Input voltages beyond the permitted...

2.4.3 Counters with Pulse Time Measurement The LAN-AD16fx features three 32-bit counters allowing the connection of incremental encoders. The counter inputs (A, B, and Reset) can be assigned to any digital lines of the two digital ports (configure by software). The LAN-AD16fx counts the number of incoming pulses (max. 16MHz) sampled at the connection of signal A. If the maximum counting range is reached, the counter will be reset to the minimum value of the counting range. If the external counter reset is connected, the counter can be reset at any time. In comparison to a counter, the quadrature...

3 Interfacing Examples for Digital Channels The following basic connection examples demonstrate the use of the digital inputs and outputs and the connection of a counter to the LAN-AD16fx. Before, however, the relating digital port must have been switched to input or output (see chapter 2.4). 3.1 Interfacing Examples for Digital Inputs The 3.9kQ pull-down resistor sets the input to low if no voltage is applied there. 3.1.1 Connecting an Optocoupler Optocouplers provide optimum protection at each input line. With them, it is possible to connect higher voltages and to protect the hardware from...

3.2 Interfacing Examples for Counters or Incremental Encoders The connection of "Signal A", "Signal B" and "Reset" is possible at any digital line. O Make sure to configure the relating digital lines as input and to assign them to the counter. Serial resistors in the digital lines limit the current and protect the hardware from being destroyed. 3.3.1 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 8). 3.3.2 Connecting a Relay A connected relay is ideal to...
