spaces are required when entering commands.
All standalone units have ‘00’ as their default address. When multiple units are used as in an
expansion configuration, each unit will have a unique address. In this case, all below commands
should start with the Prefix:
‘A zz’
, where
zz = [01-99]
and represents the units System Address.
This will ensure the commands are sent to the correct unit.
