Revised 04/27/2011 Copyright 2011
Welcome to Dynalab
Thank you for selecting Dynalab Test Systems. The NX Tester is designed to run as a standalone wire
harness tester without a constant connection to a computer. Programs are created with the NX Editor
software application, then transferred to the NX Tester.
This User’s Guide describes the NX Tester’s user interface, hardware configuration, and interfacing.
Please refer to the NX System Getting Started Guide to learn how to quickly set up the NX Tester and
write a functional test program. Detailed information about how to write test programs is available in
the NX Editor User’s Guide.
Overview of the Dynalab NX Tester
The front panel of any NX Series Tester has the following features:
•Speaker – The speaker is used to produce a variety of sounds.
•Display – The 4 line x 20 character display provides useful information about the status of the test.
•User Buttons – The arrow buttons are used to scroll through menus. The green button is used to select
menu items and to start programs. The red button is used to stop program execution and to escape
from menus.
•Probe port – This accepts the Probe, a useful device for troubleshooting fixture wiring. When probing
a Test Point, the Tester will display the Test Point name.
•NX Memory Card Slot – This slot accepts an NX Memory Card for the purpose of transferring
programs from a PC to the NX Tester.
•Key Slot – This slot accepts a Supervisor Key
The Supervisor Key unlocks access to Setup Menus, allows program termination, activates the
control port, and allows advancing through errors. The Supervisor Key may also be used to satisfy a
test program’s requirement that a supervisor be present to continue. The Supervisor Key contains
data storage areas that can be programmed to contain the Supervisor’s ID and other useful data.

The rear panel of any NX Series Tester is designed to support the following features:
•Serial Ports – Two serial ports are supplied as a standard feature on every NX Series Tester. Serial
ports are used to connect to a Remote Display, Label or Receipt Printer, or Bar Code Scanner. Two
additional serial ports and a network interface are available with the optional Communications Board,
part number 5-4011.
•Power Supply Receptacle – this accepts the DC connection from the Power Supply.
•Control Port Interface – Connects to the Control Port Module. The Control Port Module provides one
set of contacts for output and one for input. This provides a mechanism to control an external device
such as a fixture clamp, or to receive input from an external device. For more detailed information
regarding the use of the Control Port Module, please refer to the NX Application Note entitled
Interfacing to External Devices.
•Extended Button Interface – In some cases, the test operator may not be able to easily reach the
control buttons on the front panel of the NX Tester. To solve this problem, the NX Tester can be
equipped with an Extended Button Pad - this provides the operator with complete control of the NX
Tester from a distance. The Extended Button Pad plugs into the Extended Button Interface.
•USB Port – The USB port is available to connect to a PC. A PC connection is used to support NX
View software, to upgrade the NX Tester’s firmware, or to download test programs from the PC.
Note: the USB port is a standard feature in NX Testers manufactured in 2011 and later. Older NX
Testers are not equipped with a USB port.

Powering Up the NX Tester
The NX Tester is provided with a power supply and cord. The power supply connector plugs into the
receptacle located on the rear of the NX Tester. The power supply’s power cord connects to a 3 prong
power receptacle. For proper operation and safety, an adequate ground is required. The power supply
may be connected to a 115VAC or 220VAC receptacle.
The power switch is also located on the rear of the cabinet. When the power switch is activated, the NX
Tester displays a power up message that includes the firmware version, the NX Tester’s serial number,
and the number of test points, as shown below:
During the power up phase, the NX Tester performs a diagnostic test for the test points. If successful,
the fourth line displays the total number of test points found as shown above. If the diagnostic test fails,
the fourth line will display a flashing message indicating failure.
Calibration
The NX Tester performs automatic calibration upon power-up and every time a Test Workflow item is
executed. Automatic calibration is based on readings made using a set of internal precision components
of known values. Calibration of any NX Tester is verifiable using Dynalab’s Calibration Verification
Device, part number 5-1040. The NX Tester calibration verification procedure is explained in detail in
the NX Application Note entitled “Calibration Verification”.
Using NX Tester Menus
A simple Main Menu is used to control basic operations of the NX Tester.
The “>” symbol is used to point to selected menu items as shown above. All menus use the four buttons
located on the front of the NX Tester.
•The Up and Down arrow buttons are used to move the pointer
•The GREEN button is used to select an item
•The RED button is used to return to a previous menu or to stop execution of a function.

MORE: SUBSTRING
The SUBSTRING function specifies the parameters used by the Automatic Program Selection Using a
Bar Code Scanner feature. This feature is explained in detail in a subsequent section of this document.
The feature uses a bar code scanner to scan a part number or program name. When connected Serial
Port 2 the scanned barcode represents either a program name or a part number. The NX Tester will then
look for a match of the scanned data – it first will look for a program whose name matches the data. If it
cannot find a program whose name matches, it then looks for a defined part number in each program.
Once the first match is found, the NX Tester will automatically select and run the program.
The SUBSTRING function instructs the NX Tester to extract a substring from the scanned data, and use
the substring as the match criterion. There are two parameters to be set:
FIRST CHARACTER POSITION – using the up/down arrow keys, specify the first character
position of the substring, then press the green button to accept. The minimum value must be 01.
MAXIMUM CHARACTERS – using the up/down arrow keys, specify the maximum number of
characters for the substring. Note that if the remaining number of characters in the scanned data is
less than the specified MAXIMUM CHARACTERS, the substring will start at the FIRST
CHARACTER POSITION and end at the end of the scanned data. Note that even though this field
may be set to a value as high as 99, a maximum of 40 characters will be used, since this is the
maximum size of the Part Number variable. Anything beyond 40 characters will be truncated.
Examples:
Scanned barcode data is: AXRQ-9987465
FIRST CHARACTER POSITION = 06
MAXIMUM CHARACTERS = 04
SUBSTRING = 9987
FIRST CHARACTER POSITION = 06
MAXIMUM CHARACTERS = 99
SUBSTRING = 9987465
FIRST CHARACTER POSITION = 01
MAXIMUM CHARACTERS = 99
SUBSTRING = 9987465

FILE ACCESS
This function is used to restrict (or un-restrict) access to the program SELECT menu based on the
presence of the Supervisor Key. Use the Up/Down Arrow buttons to select NO RESTRICTION if
access to the SELECT menu is unrestricted, or to select SUP KEY REQUIRED if access to the SELECT
menu is to be restricted based upon the presence of the Supervisor Key. Press the Green button to
confirm the selection. Press the Red button to exit.
FILE MODE
By default, the NX Tester can store as many program files as can fit into its 1.3Mb of program storage
area. This corresponds to the MULTIPLE FILES selection.
In some cases, it may be desirable to allow the NX Tester to store only one test program at a time. To
enable this capability, select ONE FILE in the FILE MODE menu. Press the Green button to confirm
the selection. If ENABLED, after pressing the Red button to exit, if there is more than one program
currently on the NX Tester, the following screen will appear:
Upon pressing the Green button, the NX Tester will delete all files except the currently selected file, and
will place the NX Tester into One File Mode. Upon pressing the Red button, the NX Tester will delete
no files, and the One File Mode will remain DISABLED.
The selection labeled ONE-DELETE ON END 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 may be 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.

DIAGNOSTICS
The DIAGNOSTICS menu is accessible from the SETUP menu as shown above.
TEST PTS
>
Select TEST PTS to perform a diagnosis of all test point boards. Before performing this check, be sure
that all test point boards are disconnected from the interface cabling.
SER 1&2 or SER 3& 4
Serial ports may be diagnosed in pairs. To execute a diagnosis of serial ports 1 and 2, select SER 1&2,
connect the two ports together using the download cable and press the Green button. Similarly, to
execute a diagnosis of serial ports 3 and 4, select SER 3&4, connect the two ports together using the
download cable and press the Green button.
SYSLOG
The SYSLOG selection causes the NX Tester to copy the contents of its internal system log file to the
memory card. A memory card must be inserted before selecting this function. This capability may be
useful for diagnostic purposes – this file may be emailed to Dynalab for analysis.
RESET
Select RESET to perform a reset of the NX Tester. Specifically, this function deletes all programs,
initializes all counter variables, and resets all configuration settings to the factory defaults (except the
time setting).
