Make Back-up
This function is used to store the software within the
main HT22 station in another unit if you have two or
more units connected together. This acts just like a
computer back-up; if the main unit fails, another unit
can assume the role of the main unit and no data will be
lost. Once a back-up unit is established, the data is
backed up automatically, unless the units are
disconnected from one another.
Adding or Updating a Back-up
To make another unit into a back-up, or to update the
back-up, perform the following steps:
1. Enter your password and press the ENTER key.
2. Press the MENU key.
3. Press the RIGHT ARROW key five times to enter the
Maintenance menu.
4. Press the DOWN ARROW key once to select Make
Back-up.
5. Press the ENTER key. The screen will display a list
of the secondary encoder addresses, and the status of
any current back-ups, if any exist. Use the UP and
DOWN ARROW keys to select a secondary encoder.
