Mark A:
Outdoor Unit GMV-Pdm450W/NaB-M can be connected with up to 32 indoor units by two pinboards ,either of
which can connect with up to 16 indoor units . What’s more, the quantity of communication modules used is the same as
that of pinboards.
In this project, pinboard 1 is connected with the communication module with address of 02 and indoor units (address
01~04) of ofce 7-8, corresponding with independent communication Net.2. Pinboard 2 is connected with communication
module of address 03 and indoor units (address 01~08) of office 1-2, corresponding with independent communication
Net.3. The outdoor gure is as follow:

Centralized controller cabinet is mainly used to put communication modules together. Refer to Section 3 Instruction
to Installation Procedure of System about its gure and connection method of communication modules.
Mark D:
Centralized Controller ZJ701. For the rst use of it, address mapping setting must be made to specify addresses of
communication modules which should be controlled. In this project example there are 3 communication modules with the
address of 01, 02 and 03 which are displayed in the centralized controller correspondingly.
Mark S1, S2, and S3:
Telephone 3-way triple adapters are used to connect communication modules with communicating net of indoor and
