DIGITAL I/O
OMB-NET6000 Series modules include eight digital I/O lines. Alleight lines are accessible via a 9-pin female DSUB connector locatedon the rear panel of the unit. Each digital I/O bit can be programmedindividually to be either an input or an output.
COUNTERS
There are four 32-bit counters built into each OMB-NET6000 Seriesmodule. They are accessed through the 9-pin female DSUB connectorlocated on the rear of the unit. Each counter has a maximum 20 MHzinput frequency and can be used in counter or encoder (A, B, and Z)modes.
TRIGGERING
A variety of trigger modes are supported by the OMB-NET6000Series. A wide selection of programmable analog and digitaltrigger modes are available for starting an acquisition. All triggermodes, along with the number of scans and the sample rate for preandpost-trigger data, are software programmable prior to the start of ascan sequence.
SYSTEM POWER CONNECTION
The OMB-NET6000 Series modulesoffer the flexibility to be poweredeither directly from a 19 V to 30 VDCsource, or via the includedOMB-NET-TR-60U AC power adaptor.
ETHERNET FEATURES
The OMB-NET6000 Series transfers acquired data to the PCvia 10/100BaseT Ethernet, allowing a continuous stream of datato be collected and stored in a PC’s memory or hard drive.The most common and highest performance connection is withdedicated, point-to-point Ethernet link between the PC and theOMB-NET6000 Series module. With an enterprise-wide Ethernet networkconnection, any number of OMB-NET6000 Series modules canbe connected to the network.
MULTI-UNIT SYNCHRONIZATION
Multiple OMB-NET6000 Series modules can be synchronized via therear-panel SYNC ports on each unit. After connecting each module to anEthernet port, simply connect multiple OMB-NET6000 Series modulestogether using SYNC cables (OMB-CA-74-1). Encore softwareprovides the capability of setting one of the OMB-NET6000 Seriesmodules as theｍａｓｔｅｒand the others as slaves. The sampled data phaserelationship among channels between multiple devices is dependent on the“Channel SYNC Skew” specification for each device.
ENCORE SOFTWARE Overview
Encore is a premier data acquisition software package and is includedwith each OMB-NET6000 Series module. Encore combines ease ofuse with advanced functionality, including customizable data layouts,powerful analysis, and reporting capabilities. Instead of having aprogram to log data, another to analyze, and a third to developreport data, Encore includes the functionality of all three into onepackage, thus shortening the learning curve, and saving time and cost.
CONFIGURATION
Easy-to-use set-up wizards provide rapid hardware configuration.Encore allows you to go from setup to taking measurements in minutes.Users can select one or more available devices from Encore’sHardware Configuration dialog. Encore allows you to configurethe basic acquisition or generation options, such as channel selection,acquisition rate, number of points, and input range. You can alsoconfigure start and stop triggers. In addition, within the Channel Viewtable, users can enable (or disable) channels, select measurementtype, enable logging, perform mx+b calculation, and more. ChannelView configurations can also be shared among multiple projects.
MEASUREMENT
Encore allows you to develop data displays quickly with an intuitive,drag-and-drop interface. Encore also offers the ability to easilychange plot colors, overlay channels (including previously recorded data),and access multiple devices. You can also display data in a varietyof ways including; charts and graphs, meters, gauges, and tanks.Additionally, you can export data to other formats including Excel, ASCIIand DIAdem.
TRIGGERING
A variety of programmable analog and digital trigger conditions areavailable for starting and stopping an acquisition within Encore. Analogtriggers include Rising Edge, Falling Edge (with hysteresis), Above Level,Below Level, Inside Window, and Outside Window. Digital triggersinclude Rising Edge, Falling Edge, Level High, or Level Low. Inaddition, the Duration trigger may used to stop an acquisition after aspecified time.
ANALYSIS
Included analysis options make Encore an advanced softwarepackage. Features include FFT, power spectrum, statistics, peakvalue, and RMS calculation. In addition, you can also create customformulas using Encore’s Create Calculated Signal function. Data canalso be viewed in the playback work area. Analysis can be computed onlive data as well as logged data (post processing).
ANALYSIS OPTIONS INCLUDE:
• Statistics: Standard Deviation, Mean, and Variance
• Peak: +Peak, -Peak, and Peak-Peak
• RMS
• DC
• FFT

• Minimum
• Maximum
EXPORT TO EXCEL®
Signals can be exported from Encore to Microsoft Excel. When exportingsignals from Encore to Microsoft Excel, the following information isexported:
• Signal name
• Export date and time
• Signal units
• Data values
Encore offers sophisticated, builtin test reporting capability whichprovides the ability to present data in a professional manner. WithEncore’s test report capability, users can easily develop in-depth testreports. Within Encore’s Project Report tab users can drag signalsfrom the application directly into the report and then enter text, changefonts, import images and print or export reports. Once the report iscomplete, you even have the ability to acquire new data and easilyupdate any previous report, without re-creating the report. The report canbe edited throughout the life of the project.
