USING THE LOADER UTILITY
The Loader utility can operate from any DOS directory or drive on your PC. The program is comprised of three parts:
Program Card (authorization procedure), Setup (communications configur ation) and Terminal (terminal emulator). The
main screen is shown in Figure 12.

If you are running Loader for the first time, be sure to access the Setup menu (step 3 below) before proceeding to
Program Card (step 4 below); otherwise, you can skip step 3. The procedure is as fol lows:
1. Turn off power to the MiLLennium.
2. Start the Loader program.
3. From the main menu screen, select Setup to configure the serial port over which communication will occur
(default: COM1) , and the data transfer rates for both programming (defa ult: 115 200 bits per second) and term inal
emulation (default: 9600 bps). To minimize the time required, select the highest serial bit rate your PC can reliably
support. Loader will verify and save your selections in a file named LOADER.SET, and return to the main menu
screen.
4. From the main screen, select Program Card.
5. Select the disk drive (e.g., A, B, C, D) in which the update file (e .g. 442.BIN) is located. Select the path where the
update program file is located (e.g., C:\GPS\LOADER); the directory from which you start ed Loader is the default
path. Select the required update file (e.g. 442.BIN).
6. At the prompt, enter your update auth-code (e.g. 17b2,32df,6ba0,92b5,e5b9,millenrt2).
7. When prompted by the progr am, turn on power to the MiLLennium. Loader will automatically establish
communications with the MiLLennium. The time required to transfer the new program data will depend on the bit
rate, which was selected earlier.
8. When the transfer is complete, use a terminal emulator such as that in Loader (select Terminal) to issue the
VERSION command; this will verify your new program version number. When using the terminal emulator in
Loader, a prompt does not initially appear; you need to enter the command first, which then produce s a response,
after which a prompt will appear.
9. Exit Loader (select Quit).
This completes the procedure required for field-updating a Mi L Lennium.
