For a Master-Slave configuration, each ACU in the Master-Slave set will need to be configured
separately. When you add an ACU, the Master ID will default to 0 to indicate that it is a standalone
ACU. You will need to change the Master ID to a 1 for the Master ACU. When you add a Slave ACU,
use the same IP address as the Master ACU, but change the Master ID to correspond to the Slave
ACUs ID in the range of 2-4. When the ACUs are polled, the application will append the Master/
Slave ID to the Unit ID to make tracking easier.
