30 N
31 A
32 B
RS485 communication port
RS485 connector used for communication via BACnet, or for master/slave
communication via Exoline or Modbus.
N can be used as common signal reference if a large difference in potential
between units in the network is causing communication problems.
This connection is galvanically isolated.
40 N
41 A
42 B
RS485 communication port
RS485 connector used for communication via BACnet, or for master/slave
communication via Exoline or Modbus.
N can be used as common signal reference if a large difference in potential
between units in the network is causing communication problems.
This connection is not galvanically isolated.
