Upload Procedure and Part Number Verification of the Loadable Software Parts (LSP) in the Wireless Ground Link-Digital Access Recorder (WGL-DAR)

TASK 31-36-00-710-803-A
Upload Procedure and Part Number Verification of the Loadable Software Parts (LSP) in the Wireless Ground Link-Digital Access Recorder (WGL-DAR)

CAUTION: OBEY THESE PRECAUTIONS TO PREVENT ELECTROSTATIC DISCHARGE (ESD) DAMAGE TO THE COMPONENTS:

STAY ON A CONDUCTIVE SURFACE THAT IS ELECTRICALLY GROUNDED.
USE A CONDUCTIVE WRIST-STRAP THAT IS ELECTRICALLY GROUNDED. (CONNECTED TO A BONDING-POINT NEAR THE WORK AREA).
BEFORE YOU USE THE TOOLS, MOMENTARILY HOLD THEM AGAINST AN ELECTRICAL GROUND TO RELEASE STATIC ELECTRICITY.

NOTE: You can use different vendor-supplied methods (for example, CF card) as an alternative procedure to upload the software in the WGL-DAR. VSB 2243800-31-27 contains the vendor instructions to do this software upload.

Subtask 31-36-00-710-148-A ** ON A/C NOT FOR ALL

A. Part Number Verification of the Loadable Software Parts (LSP) of the Wireless Ground Link-Digital Access Recorder (WGL-DAR)

NOTE: This procedure lets you do a check of the part number(s) of the LSP, to make sure that you have the correct LSP. You can do the check of the part number on the WGL-DAR display.

(1) Before you start the procedure, you must make sure that you know the part number of the LSP that you installed in the WGL-DAR.

NOTE: If you cannot find the LSP part number, contact the vendor customer services.

8.Do a check of the LSP part number on the display. NOTE: If other LSPs are installed, do again the previous 2 steps.	NOTE: Make sure that the part numbers of the OPS and AII are the same with the part numbers written on the software media. NOTE: You can have different configurations of the LSP part number on different A/Cs. If the LSP part number does not come into view or it is different than the one you know, contact the vendor customer services.
