HHT mode), choose the address, and press down
arrow. (The user can also set the baud and parity,
19200 and no parity is recommended)

Pressing the down arrow may show you the next

PROCEED?: NO
The HHT will ask if you are connected to the ACC
that you wish to communicate with directly; the user
has to be connected directly to set the address of an
ACC. Press the left or right arrow keys to display the
arrow next to the NO (default). Press the - (dash) key
to toggle it to YES.
Once the address (and/or baud and parity) is
changed, you will be connected in ACC HHT mode
and you will see the ACC Home Screen. See Section
8.5.4. for more details.
NOTE: If the address is already pre-set on the
ACC using the dip switches, the address cannot
be changed with the HHT. The pre-set dip
switches on the ACC will always take priority.
