Communication-link wiring and addressing

Communication-link wiring and addressing

The Tracer ZN521 zone controller communicates with the BAS and with other LonTalk controllers by means of a LonTalk communication link.

IMPORTANT

For important instructions on network wiring, refer to the Tracer Sum- mit Hardware and Software Installation guide (BMTX-SVN01A-EN).

Wiring for the communication link must meet the following require- ments:

All wiring must comply with the National Electrical Code and local codes.

22 AWG Level 4 unshielded communications wire recommended for most Comm5 installations.

Termination resistors are required for wiring LonTalk devices com- municating on a network. For specific information about using termi- nation resistors for LonTalk applications, refer to the Tracer Summit Hardware and Software Installation guide (BMTX-SVN01A-EN).

Each Tracer ZN521 zone controller has a unique 12-character alphanu- meric device address for communicating on a BAS network. This address, referred to as a Neuron ID, is assigned in the factory before the product is shipped and cannot be changed. Each controller can be identified by view- ing its unique Neuron ID, which is on a printed label attached to the cir- cuit board of the controller. Additional adhesive-backed, peel-off Neuron ID labels are tethered to the controller for placing on mechanical prints or unit location worksheets. The Neuron ID will appear when communica- tion is established with the Rover service tool or a BAS. An example Neu- ron ID is 00-01-64-1C-2B-00.
