Before starting inspection, refer to version.txt in the same directory as the firmware shown on the previous page and input the
version character string as instructed. (Please refer to page 24, 25)
B. Inspection Method
The inspection configuration is shown in the diagram below.
Install the inspection jig to the AI8 to be inspected as in the figure above. Send the inspection commands from the PC via the AI8 to the
LMY-slot inspection jig and take in at the PC the results returned from the LMY-slot inspection jig. Always switch on the Phantom
switch before starting the inspection. (The pop-up box is displayed on the PM1D inspection PC software when the checks start.)
* Turn on the power supply for AO8 before making the connection between the AO8 on the jig side and the jig for serial
communication. Warning: Do not connect until "" is displayed on the AO8 7-segment display.
* Use the LMY-slot inspection jigs inserted into the LMY-slots. For details, see the LMY-slot inspection jig
specifications.
* Serial communications jigs are boards that convert the serial interface from the PC. For details, see the LMY-slot
inspection jig specifications.
* Set the DIP switches on the ID change jig for AI8 inspection as shown below. For details on the IC change jig, see
the LMY-slot inspection jig specifications.
The AI8 is inspected using PC inspection software. This inspection software is common for AI8/AI8/DSP1D/CS1D. For the basic
operation methods, menu screen specifications, etc., see the CS1D Test Program Specifications.
Below is the menu for AI8 inspection.
Input the latest version of AI8 UNC before starting the inspection. (This is necessary for the version check.) For the character string
to input, refer to version.txt in the same directory as the AI8/AI8 firmware. Details of each check item and the corresponding PC
software are shown on the following pages.
