Make sure the LMC-1 is turned on, and that the adapter is connected to both it and your computer.

Click your 'Start' Menu, select 'Programs', and select 'Update' from the program menu.

Select the Com port you identified in the previous step from the drop-down menu.

Click 'Get Ver' (Get Version), and make note of the current version installed in your LMC-1. (In the illustration above, it is Ver:5.15).

Now, you will actually load in the new code for your LMC-1. Select 'Open'. This will give you a window showing the two .hex files to chose from.

Select a .hex file from the menu (as shown above). If your 'version' is code 6xx, select the v621.hex - for all other codes, select 515.hex.

Click 'Start' to upload the code to the LMC-1.
