Notes:
• Do not connect more than 4 System Controllers in a
daisy-chain connection as unstable operation of the
system might occur.
• In the above connection, the operations may be acti-
vated with poor response.
It is recommended to connect the System Controllers
in a Home Run type of connection if operating the
plural controllers at the same time.
