The OM-USB-1208FS, OM-USB-1408FS and OM-USB-1608FS are USB 2.0 fullspeed voltage input data acquisition modules (fully compatible with both USB 1.1 and USB 2.0 ports). These are plug-and-play modules which draw power from the USB cable–no external power supply is required. All configurable options (including individual channel ranges) are software programmable, and the modules are fully software calibrated.
The OM-USB-1208FS and OM-USB-1408FS feature eight analog voltage input channels that are processed through a single A/D converter. The analog inputs to the OM-USB-1208FS are software configurable for either eight 11-bit single-ended or four 12-bit differential inputs. The analog inputs to the OM-USB-1408FS are software configurable for either eight 13-bit single-ended or four 14-bit differential inputs.
The OM-USB-1608FS offers true simultaneous sampling of up to eight 16-bit single-ended analog voltage input channels which is accomplished through the use of an individual A/D converter per channel. Models USB-1208FS and USB-1408FS have 16 independent digital I/O channels and model OM-USB-1608FS has 8 digital I/O.
All modules have one 32-bit counter channel. The digital I/O channels are software programmable for input or output. Additionally, models OM-USB-1208FS and OM-USB-1408FS have two 12-bit analog outputs. The packaging for the OM-USB-1208FS, OM-USB- 1408FS and OM-USB-1608FS ensures ease of use in a variety of applications.
The OM-USB-1208FS, OM-USB-1408FS and OM-USB-1608FS modules ship with an impressive array of software, including the new 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 v8.5 through 2012) and InstaCalTM installation, calibration and test utility-powerful solutions for programmers and nonprogrammers alike. These modules operate under Microsoft Windows? XP (32-bit only) and VISTA/7/8 (32-bit and 64-bit) operating systems.
The OM-USB-1208FS, OM-USB-1408FS and OM-USB-1608FS data acquisition modules are 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
