ViewStat Installation and Wiring
18 ViewStat Communicating Thermostat
Connecting to a LandMark Control System
PhastLink cables are used to connect all PhastLink-compatible devices, including keypads, dimmers, J-box IR
devices, amplifiers, audio switches, etc. The table below lists the RJ-45 pinout information.
PhastLink uses a standard 10Base-T connection (i.e. Category 5 wire and RJ-45 connectors). The wire should
be connected in the standard manner. If a consistent color code is used, wiring problems will be minimized.
It is important that the correct pairing is observed. Transmit, Receive, and Mic need to be on twisted pairs.
Splitting pairs (e.g., using a white/green wire with a blue/white wire for transmit) will result in increased
crosswalk, and may result in bus failure or noise on the intercom.
Installing the Cat5 Suppression Ferrite
Before connecting the ICSNet cable, install the Cat5 Suppression Ferrite (provided), as described below (no
tools required):
1. The Cat5 suppression ferrite is housed in a plastic enclosure, with a latch release on one side. Pull to
release the latch and open the enclosure.
2. Insert the Cat5 cable.
3. Snap the enclosure shut with the cable inside, and you’re done.
Connecting to a NetLinx Control System
To connect a single ViewStat to a NetLinx control system, use ICSNet cabling to connect the
RJ-45 jack on the ViewStat to any available ICSNet jack on the NetLinx Master. The maximum cabling
distance between the ViewStat and Master is 1,000 ft (304.8 m).
To connect multiple ViewStats to a NetLinx system, use a NetLinx Hub (NXC-NH) to add additional ICSNet
ports to the system, connect the RJ-45 jack on the ViewStat to an available ICSNet jack on the Hub.
