INTRODUCTION TO WIRE LIST PROGRAMMING
DISCUSSION
Before a test can be performed on an assembly, a Wire List program must be created. The
Program Editor can be used to create the entire Wire List program or parts of the Wire List.
There are three major functions in wire list programming:
WIRE LIST (FROM/TO LIST)
CROSS REFERENCE LIST
SETUP OPTIONS
Wire List
The wire list is a tabulation of tester point numbers representing all wires or circuits in the
assembly. Tester point numbers are listed in pairs, each pair representing the two terminating
locations of a wire or circuit, the FROM/TO points. Therefore, the wire list contains the
FROM/TO point assignments for all continuities.
The Wire List can be keyboard-entered into the Editor or learned by the Learn Known Good
mode. For most build applications however, the wire list is keyboard-entered. The line-to-line
sequence of FROM/TO points in the Wire List also becomes the build sequence for Sequential
Build mode.
User Notation List
The user notation list relates tester point numbers in the wire list to their corresponding harness
connector/pin numbers. (User Notations are also referred to as cross references, user labels, and
point IDs.) Each unique user notation used in the wire list must have a tester point number
assigned. The user notation is determined by the wiring relationship from the back of the
scanner boards, through the interface cables, and the test fixture wiring. User notations cannot
be learned; they must be keyed in. User Notations are maintained when an existing wire list
program is used to save continuities when relearning a known-good assembly.
Setup Options
Setup Options enable you to control test parameters such as test speed and the number of test
points to use. Typically, setup options are maintained in their default states. Test time for small
harnesses can be decreased by limiting the number of test points scanned. Test time is decreased
using the Maximum Board (MB), and Maximum Point (MP) commands. Refer to the Setup
Commands for programming information.
The setup options are retained until changed by loading a program with
different settings, by keyboard changes to the setup commands, or by using the
default funtion from the front panel.
especially the maximum board (MB) and maximum point (MP), are set for the
number of test points required to learn and test the new assembly.
CAUTION:
Verify that the Setup Commands,
