(1) NETWORKING 

(1)  It is possible to network up to a maximum of 8 units to a single LINKS 2.  Since each 

unit is separately addressed, it is possible to monitor and control each unit 
individually.  Different networking configurations may be achieved and are mostly 
dependant on the type of network present at the site.  One networking example could 
have a Gateway installed inside the lead unit, which could then be daisy-chained to 
successive units.  In turn, the lead unit would connect to a Building Management 
System (BMS) network via a shielded, twisted-pair connection.  Please see wiring 
section for additional detail.  A second example could have a series of units directly 
connected to an Ethernet network. This is only possible for BACnet communication 
and is essentially referred to as a BACnet/IP configuration.
