Procedure

Identify the appropriate database you wish to program into the ROM pack.

NOTE:
This database information is subject to change. Refer to the MEDIC screen to confirm current database numbers and for new reprogramming issues. DO NOT USE OLD DATABASE INFORMATION. USE ONLY THE LATEST VERSION DATABASE AS POSTED IN MEDIC AND ON THE MEDIC WEB PAGE IN DIAMOND DEALER LINK.

If your memory card is marked "128 KBYTE", locate the 256 KBYTE memory card (p/n MB991717) supplied with the Interface Cartridge. You can also use MB991500, which has 256 KBYTE memory.

4. Make the following electrical connections:





a. Connect the serial data cable (with the flat side facing down) to the MUT-II.
