• Probe Assisted Test Point Assignment: This is a new method for assigning test points in the NX Editor. The user touches the point to be assigned with the NX Tester’s probe, and the NX Editor automatically populates the corresponding data in the Fixture Blocks table. The NX Editor communicates with the NX Tester using the serial transfer cable.
• Probe Assisted Assembly: The probe function during a Test-Display workflow item has been enhanced to also include the connector-pin information of the other end of the connection. The tester resumes testing when the connection is made or if either the red or green button is pushed
• Continuous Testing: The Test-No Display workflow item has been enhanced to support continuous testing. This enables operators to flex a wire harness or cable assembly for a specific duration to test for intermittent open or short conditions. If an error is found during the specified duration, execution jumps to another cell in the workflow for error handling. The continous testing mode is terminated by specifying a specific time interval, by specifying a specific number of test cycles, or by having the operator press the green button.
• Immediate Miswire Display: The Test-Display workflow item has been enhanced to allow for the selection of a new capability: Immediate Miswire Display. When selected, the NX Tester will immediately display a miswire condition.
• Enhanced Early Exit Critiera: The Test-Display workflow item has been enhanced to allow for either a short condition or early removal to trigger a jump to another workflow cell. Previously, these were mutually exclusive conditions for triggering early exit from the TestDisplay workflow item.
• Enhanced Report Capabilities: The Report workflow item has been enhanced to provide additional flexibility for generating reports where there are multiple Test workflow items and/or multiple phases.
• Hipot Fixture Diagnostics: This has been added to the NX Hipot Tester’s diagnostics menu. When selected, it causes the tester to execute a hipot test using the settings of the currently selected program. This is intended to be used on an empty fixture as a way of validating the fixture’s suitability for hipot testing.
• Enhanced Hipot IR Testing: The Hipot Insulation Resistance testing range has been extended to 1500 MOhms.
• Repeating sounds in the Test-Display workflow item are now functional.
• If a short error is encountered during testing, once all errors have been resolved, a re-test is automatically executed. This ensures that the short error was not resolved by removing the shorted connection from the fixture. Previous firmware versions would re-test only if short errors were present after all connections were satisfied.
• An open detection switch is now indicated by displaying “SWITCH OPEN” on the first line and the detection switch name on the second line.
• In the PROBE mode, an up-arrow is displayed in the upper right corner preciding the C (^C), if more than one point is connected to the probed point. This is intended to prompt the user to use the up-arrow button to scroll through all the points connected to the probed point.
• Kelvin testing speed has been improved.
• After a hipot test, the Report workflow item will now show hipot IR values.
• The Dielectric Withstand test has a new error: DW-CURRENT. This indicates that the error condition may be caused by insufficient current or voltage settings.

• Improvements have been made to the NX Tester’s file system, allowing for improved performance of memory cards. In previous versions, the NX Tester could at times get into a state where it could not read a memory card without cycling power. This has been resolved.
• Relay testing speed has been improved: over a 50% reduction in test time.

• Thermistor testing: Release 10 supports a new Component: Thermistor. Thermistor testing is accomplished by comparing a thermistor in a wire harness to a reference thermistor.
• NX Editor Password Security: A simple password security scheme has been implemented to protect programs from unauthorized changes. The Editor now has two states, “Locked” and “Unlocked”. Unlocked has full functionality, locked limits the user to operations that do not alter the current program. There is a new “Security” tab on the Editor Options dialog that allows a user to set a password. Once set the password is required to unlock the Editor. The lock state is persistent so if the Editor is restarted the lock state is preserved. The password is stored on a per-machine basis (all users have the same password).
• Hexadecimal Representation of Counter Variable: Any counter variable can be converted to its hexadecimal equivalent for the purposes of displaying or printing the variable’s value.
• In the NX Editor, the “Add Connections” window now remains open until closed by the user.
• In previous releases, the NX Editor would respond very slowly to changes made in the Connections View of very large programs. This response time has been optimized.

• Enhanced Automatic Program Selection: The Automatic Program Selection feature of the NX Tester has been enhanced to include a substring function. This enables the NX Tester to match on a substring of the scanned data instead of matching the entire scanned string.
• The NX Firmware now has the capability to support super-netting schemes, resulting in greater reliability in a networked environment.
• Several bug fixes are included that improve the optional ABR functionality.
• Probe mode during test now displays the wire color as well as the wire name.

• New File Mode Restriction: A new restriction option has been added to the NX Tester’s FILE MODE menu: “ONE-DELETE ON END”. It is similar to the ONE FILE mode, with the additional feature of automatically deleting the program file after execution, providing that the program reaches a END workflow item. This is useful in conjunction with using the NX Server as source of all program files, ensuring that program files are only available from the NX Server.
• More Flexible Write Workflow Item: The Write Workflow Item now has a checkbox, enabling the user to disable appending CR/LF to the Write output.
• Limited Short Scan Option: The Test Workflow Item now has a checkbox, enabling the user to select a Limited Short Scan mode when testing a single phase. This provides some additional flexibility in testing harnesses that contain switches or shorting caps.

• Enhanced Network Capabilities: NX Testers now support full networking capabilities, including sending detailed wire harness data to Dynalab’s NX Server Enterprise Edition for archiving and reporting.
• Enhanced Autolearn: NX Testers now support the use of a template file with the Autolearn function. This feature provides additional flexibility when automatically ‘learning’ a wire harness. The Autolearn template file allows for customization of the workflow, definition of variables, wire colors, or other program properties, custom naming of fixture blocks/pins, and specification of additional connection phases.
• Calibration Verification: NX Testers have always performed automatic internal calibration tests upon startup to ensure accurate measurements. Now, the Calibration Verification Tool is available from Dynalab to verify that the NX Tester is performing in accordance with its published accuracy specifications.
• Enhanced Control Port Module: New NX Testers support an enhanced Control Port Module that consists of two independently controllable outputs. This is useful for wire harness testing applications that require independent control of two electrically-operated devices such as a fixture clamp release solenoid, a marking device, etc. (This capability is only available with new NX Testers whose Control Port is specially labeled indicating support of the dual output Control Port Module.)
• Flexible Testing Modes: To support reliable testing in applications with high levels of wire capacitance or high levels of electrical noise, the TEST Display Workflow Item provides a choice of Threshold or Actual testing modes. Threshold testing is the default mode. It provides the fastest performance and is suitable for most testing situations. Actual mode testing is available for situations where actual resistance measurements are to be reported; however, this mode may not be suitable in testing environments with high wire capacitance or high levels of electrical noise.
• Enhanced Probe Capability: The probe is now active during testing. While a test is executing, if any point on the fixture is probed, the NX Tester will display information about the probed point.
• Enhanced NXI File Importation: The NXI File import capability has been enhanced to support multiple part numbers.
• Network-Enabled Automatic Program Selection: If a NX Tester is network-enabled and is registered with a NX Server, use of a scanner for automatic program selection will include the network drive when searching for programs.
• Improved Power-Up Diagnostics: If a test point is shorted to ground, the power-up diagnostics now provides identification of the shorted test point.
• In previous versions, the NX Tester would not properly Autolearn a wire harness containing diodes with spliced cathodes. This problem has been fixed in this release.
• In previous versions, the NX Tester would not always recognize the presence of a Supervisor Key or Operator Key when executing a User Interface cell that was configured to wait for the key to be present before continuing. If the key was already present, the operator had to remove the key, and then re-insert the key. Now, the NX Tester correctly senses the presence of the required key.
• In previous versions, the $SEC variable (represents seconds) did not have a leading ‘0’ when the value was less than 10. It now is padded with a leading 0 for the values 1-9.
• In previous versions, the NX Tester would not see a short between test points that are 8 points apart above test point 1-64.
• Several improvements to the NX Editor.

• Saving System Log to Memory Card: The Diagnostics Menu of the NX Tester now has an entry labeled SYSLOG – this will copy the contents of the system log to the memory card. This feature may be useful in helping Dynalab support personnel analyze problems reported by customers.
• The NX Tester Firmware version inlcuded in the previous release (Release 6, Firmware Version 2.0.82), has a bug that results in re-testing of the wire harness whenever a short error is encountered. This can lead to unnecessary additional testing time for large wire harnesses, especially on fixtures that have intermittent connections. Release 6.1 (Firmware version 2.0.89) fixes this problem.

• Test programs created with NX Editor Version 1.0.5.84 or later can only be executed on NX Testers equipped with Firmware Version 1.4.50 (issued in Release 2) or later.
• Programs created in the NX Editor prior to Version 1.0.3.62 must be loaded and resaved in a later version of the NX Editor before the program will run on Firmware Version 2.0.77 or later.
• Illumination of Fixture Mounted LEDs for Guided Assembly: For test fixtures that are equipped with an LED (Light Emitting Diode) on each fixture block, the NX Tester can illuminate the LEDs associated with an open circuit. This enables the operator to immediately identify the location of the circuit to be completed, facilitating guided assembly.
• Improved Printer Support: Dynalab’s NX Testers can now support virtually any serial label printer. Note: Label Printers sold by Dynalab are certified to be compatible with NX Testers – other label printers may be compatible, but this is not guaranteed.
• Rotary Line Printing Solution: Dynalab’s NX Testers and the NX Server software now support multiple testers on a rotary line communicating over a wireless network with a single print server. This enables the printing of a label as each wire harness is completed on the rotary line.
• In previous versions, the NX Tester could occasionally freeze up, requiring a recycling of power. The cause for this problem has been identified and fixed.
• In previous versions, there was a problem with the date transition from one month to another, resulting in the NX Tester displaying or printing an incorrect date. The cause for this problem has been identified and fixed.
• In the NX Editor, the Test Relay workflow item was not accepting valid connection points for Relay Point Assignments. This has been fixed.

• Networking: NX Testers equipped with Firmware Version 2.0.77 are now fully networkable. To take advantage of the networking capabilities, the NX Tester must be equipped with the Communications Board option. The NX Server Standard Edition software is also required to implement networking.

• Enhanced Audit Errors: The NX Editor’s audit feature now generates an error message if a splice has only one wire connected or if a component only has wires connected to one side.
• Connections View Insert Order: In the Connections View, when inserting a new connection, the new connection is inserted after the currently selected connection rather than before as in previous versions.
• Report Shorts Only: The Report Workflow item now has a checkbox to allow only shorts to be reported. This option is only available when directing a report to the Tester’s display.
• Autolearn Default Threshold Values: The threshold values for continuity and shorts has been changed to 1000 ohms for the Autolearn mode.
• Get Measured Value Function: A new function is available for expressions: $GMV. This function returns the measured value of a component. This enables the capability to print or report the measured value of a specific component.
• Enhanced Probe Mode: The Probe mode now can display the wire name and wire color associated with the probed point.

• Reporting: NX Testers can provide a report of a completed wire harness test. The report can be directed to Dynalab’s Report Printer or to a serial port. The report provides detailed data for each circuit tested in the wire harness.
• Autolearn: NX Testers are capable of learning from a known-good wire harness. Although Dynalab recommends use of the NX Editor to develop a test program, we recognize that many of our customers prefer to use a tester that “learns” a wire harness configuration. Dynalab offers the best of both approaches – the NX Tester can learn a configuration and the resulting program can be edited and enhanced using the NX Editor.
• Enhanced Component Testing: The NX System now allows the user to specify the forward voltage for testing a diode – this allows for greater flexibility in testing a wide range of diodes that may be part of a wire harness. Additionally, the NX System allows the user to specify parameters describing a “Generic” two-port component. This provides significant flexibility in testing a wide variety of wire harness components.
• Data Import Wizard: The NX System now provides a Wizard for data importation. Data can be imported from an external file or another Dynalab test program, including PASS programs for XL Series Testers.
• Copy/Paste of Workflow Cells: Individual workflow cells can be copied and pasted both within a single instance of the NX Editor and between multiple instances.
• Duplication of Phases: A new button has been added to the Phase pane of the connections view for the purpose of created a new phase the same entries.
• Fourth Line Display: In the Test-Display Workflow Item, the 4th line option to display the part number ($PRT) has been replaced with an option to display the value of a user-defined expression.
• Default Thresholds: In the Test-Display Workflow Item, the default threshold value for continuity and shorts testing have been changed to 1000 ohms.
• New Time Variables: Two new variables have been added: Timer Tick Count ($T32) and Week of Year ($WOY). Timer Tick Count represents the number of elapsed seconds since Jan 1, 1998. It is useful for calculating time intervals. Week of Year represents the week of the year as defined by the ISO 8601 standard.
• Monitor Green Button: A new workflow item has been added – Monitor Green Button. This workflow item enables continuous monitoring of the Green button, and specifies where the cell to which the workflow jumps when the Green button is pressed.
• One File Mode: The NX Tester supports a One File Mode – in this mode only a single program file is stored in memory. This mode is selectable in the RESTRICTIONS menu.
• NX Editor Splash Screen: The NX Editor splash screen no longer appears automatically upon startup.
• Expressions: Any ASCII character value can be placed in a string literal by using the syntax $0nn where nn is the two-digit hexadecimal ASCII value of the character.
• Firmware screen: The INFO function has been added to the CONFIGURATION menu. This function displays all the firmware versions on the NX Tester.
• Enhanced error information: The NX Tester provides meaningful ERROR codes and messages that are documented in the NX Tester User’s Guide.

• Automatic program selection using a bar code scanner – The NX Tester now supports automatic program selection using a bar code scanner. With the scanner connected to serial port 2, and the NX Tester at the main menu, the user can scan a bar code that represents a program name or a part number, and the NX Tester will automatically select and run the test program by matching the scanned data with a program name or with a part number imbedded in a test program. More details are provided in the NX Tester User’s Guide.
• Support for serial ports 3 and 4 – The optional communications board provides two additional serial ports. The NX Tester’s firmware has been updated to support communications via these optional serial ports.
• Serial ports hardware handshaking – Hardware handshaking is now the default setting for all serial ports. It can be modified if required. The serial port configuration has been modified to display the handshaking settings: ‘HW’ for hardware or ‘NONE’ for no handshaking.
• Extended Display – the NX Tester’s firmware has been updated to support the Extended Display. Since the Extended Display provides 2 lines x 20 characters, and the NX Tester’s default display is 4 lines x 20 characters, the messages on the Extended Display are abbreviated.
• Extended resistor testing range – previously, the maximum resistor value that could be tested was 100K ohms. Now, the NX tester can test resistors up to 2Meg ohms in value. Testing accuracy is +/-1%.
• Capacitor testing – the NX Tester now supports testing of capacitors. Capacitor testing range is 100pf (picoFarad) to 500uF (microFarad).
• When transferring all files from the memory card to the tester, the transfer process hangs.
• Cannot transfer a file from the tester to the memory card that contains a space in the file name.
• Importation of multiple diodes from a PASS program’s secondary netlist failed.
• File download caused problems in Chinese Windows 2000.
• NX Editor allows commas imbedded in wire colors.
• Test programs created with NX Editor Version 1.0.4.66 can be executed on NX Testers equipped with Firmware Version 1.4.50 or later.
• NX Testers equipped with Firmware Version 1.4.58 can execute test programs created with NX Editor Version 1.0.4.66 as well as programs created with earlier versions of the NX Editor.

•  User Interface Workflow Cell Originally, properties were associated with Flow Arrows in the workflow. The Flow Arrow properties allowed for the specification of sounds, text, time delays, user interactions, and control interactions that were to be executed as the workflow exited the workflow cell to which the flow arrow is associated.
• In Release 2, the Flow Arrow properties have been removed. The properties that had previously been associated with the Flow Arrows are now available in the new User Interface (UI) workflow item. This provides for additional flexibility, allowing transitional behavior to be specified at any point in the workflow, instead of being tied to the exit of a workflow item. A detailed description of the User Interface workflow item is provided in the NX Editor User’s Guide dated August, 2004.
• Test programs created with NX Editor Version 1.0.3.62 can only be executed on NX Testers equipped with Firmware Version 1.4.50.
• NX Testers equipped with Firmware Version 1.4.50 can execute test programs created with NX Editor Version 1.0.3.62 as well as programs created with earlier versions of the NX Editor.
