Description

The Ethernet-based OM-NET-1608 data acquisition module is a low-cost, high-speed, multifunction I/O device that measures eight analog channels at 250 kS/s aggregate with 16-bit resolution. This device also offers two analog outputs, eight digital I/O channels, and one counter input.

Ethernet Interface
The OM-NET-1608 has a built-in 10/100 BASE-T auto-negotiation, high-speed communication port. The networking protocols are TCP/IP and UDP. Once connected to the network, the device can be remotely accessed and configured through software from anywhere on the network. Only one user at a time can access the OM-NET-1608. Software is required to actively communicate with the OM-NET-1608 over Ethernet. The device does not operate as a stand-alone data logger.

Analog Input
The OM-NET-1608 provides 16-bit analog inputs that are software-selectable as four differential (DIFF) or eight single-ended (SE) inputs. The device supports input ranges of ±10V, ±5V, ±2V, and ±1V that are software-selectable per channel.

Analog Output
The OM-NET-1608 has two 16-bit, software-paced analog outputs that can be updated at a rate of 500 S/s. The output range is fixed at ±10V.

Trigger Input
The OM-NET-1608 has an external digital trigger input. The trigger mode is software-selectable for edge- or level-sensitive mode. You can configure edge-sensitive mode for either rising or falling edge. In level-sensitive mode, you can configure for either high or low level. The default setting at power up is edge-sensitive, rising edge.

Digital I/O
Eight bi-directional digital I/O bits are individually-configurable for input or output. The digital I/O terminals can detect the state of any TTL-level input. You can configure for pull-up (5V) or pull-down (0V) with an onboard jumper.

Counter Input
One 32-bit event counter can count TTL pulses. The counter accept inputs of up to 10 MHz.

Clock I/O
The OM-NET-1608 has one external clock input and one clock output for analog inputs.

Calibration
OM-NET-1608 devices are factory-calibrated. Specifications are guaranteed for one year. For calibration beyond one year, return the device to the factory for recalibration.

Software
The OM-NET-1608 module ships with an impressive array of software, including TracerDAQ^®, a full-featured, out-of-the-box data logging, viewing, and analysis application. Driver support and detailed example programs are included for Universal Library programming libraries for Microsoft^® Visual Studio^® programming languages, and other languages, including DASYLab^®, and ULx for NI LabVIEW^® (comprehensive library of VIs and example programs compatible with 32-bit and 64-bit LabVIEW 2010 or later) and InstaCal™ installation, calibration and test utility-powerful solutions for programmers and nonprogrammers alike. These modules operate under Microsoft Windows^® VISTA/7/8/10 (32- and 64-bit) operating systems.

The OM-NET-1608 data acquisition module is supplied with TracerDAQ software which is a collection of four virtual instrument applications used to graphically display and store input data and generate output signals:

    • Strip Chart—Log and graph values acquire from analog inputs, digital inputs, temperature inputs and counter inputs
    • Oscilloscope—Display values acquired from analog inputs
    • Function Generator—Generate waveforms for analog outputs
    • Rate Generator—Generate waveforms for counter outputs

TracerDAQ PRO is an enhanced version of TracerDAQ and is available as a purchased upgrade (SWD-TRACERDAQ-PRO). A comparison of some of the features included in TracerDAQ vs TracerDAQ PRO is shown on the PDF.
