are the same regardless of the
appliance or the communication protocol.
At the opposite end of the module is the connection location for
the EMS LAN connection. The EMS uses an Ethernet connection
with an RJ-45 connector. Plug the cable into the RJ-45 receptacle.
When connecting the RS-485A connections, please note the
following:
For 2-wire systems, jumper terminal A to Y. Also jumper B to Z.
Connect the RX/TX+ (plus) wire from your Building Management
System to terminal A/Y. Connect the RX/TX– (minus) wire from
your Building Management System to terminal B/Z.
For more information on connecting the ICC Gateway to your
Building Management System, please refer to the User Manual
provided on the enclosed USB key in the “Documents” folder. The
two applicable documents will be found in the Manuals.
