Ext. Disp.
External display communica-
tion port
4P4C modular connector used for communication with an ED-RU... room unit.
60 E
61 N
62 A
63 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.
70 E
71 N
72 A
73 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.
