shows an example of a sequenced set of machines where there is a single master and
three slave machines, or a group of 4 sequenced peer machines.
For the AirSmart and ES+ protocols, any machine in the sequenced network can
automatically take on the role of master or slave depending on the system configuration
and the machines running.
When using the Delcos protocol, the master machine is dedicated and selected through
the controller configuration. For any Delcos network using a Governor controller, a
machine with a Governor controller must be configured as the master of the network.
Figure 2: Example - Master with three Slave Machines
shows example RS485 wiring connections from the master machine to each of the slave
machines in the sequenced system of machines. The communications interface must form a bus
structure so that all compressors are connected in series.
