Downloading the Remote Software
Downloading LIGHTWARE 19 software for the BCC III and the MCC
with a 4 Meg Flash card requires a two step procedure. You download
the software for the MCC first and then download the software for the
BCC III. Because the system only accepts software that is compatible,
the system will inform you of the status of the software during the
download process.
Note that upgrading software for the BCC III with a 4 Meg Flash
card always requires you to download the software for the main
control card first.
1. Back up the database.
Refer to Backing Up a Customer Database (page 27).
2. Load the new operating software from the PC.
Select the following commands from SYSTEM maintenance:
DATABASE
SW_RESTORE
ENTER
3. Select CONFIRM if you agree with the terms stated in the window.
