OPERATING INSTRUCTIONS
INTRODUCTION
The following detailed procedures are provided for acquainting the new user with the Model
256/PC. Once the details are understood, abbreviated routines, such as those in Figures 4 - 11,
will be sufficient.
LEARN KNOWN GOOD
Before testing, it is necessary to prepare a program for the harness to be tested, unless a program
already exists. This is done through the LEARN KNOWN GOOD mode, which requires
engagement of the ENABLE plug on the rear panel. A complete programming procedure, using
a known-good harness, is provided below. Once familiarized, however, the user may need only
refer to Figure 4.
1. Engage ENABLE plug on the rear panel.
2. Connect known-good harness through interface wiring to the rear panel test connectors.
3. Press Up or Down arrow to step through the MENU until LEARN KNOWN GOOD is
displayed.
4. Press MENU RUN to initiate LEARN KNOWN GOOD. The Model 256/PC will
instantly scan the known-good harness and store its configuration (wire list) in memory,
along with a signature code for that configuration. The display will show:
Learned (Signature code #)
5. If printer is connected, select and initiate PRINT WIRE LIST. Notice that the printout
also will bear the signature code shown on the display. Refer to the Wire List Printing
procedure. A sample wire list printout is provided in Figure 16.
6. Retain the wire list for future use in identifying the program just created. If no printout
was made, write the displayed signature code on paper for future use.
7. Follow SAVE function routine to save wire list program.
8. Disconnect known-good harness from Model 256/PC.
