OVERVIEW
The nLight Bridge increases the number of lighting control zones in an nLight system.
This ability stems from the fact that each Bridge has up to 8 RJ-45 ports into which zones
of daisy-chained nLight-enabled devices can connect. The Bridge also is an integral
component of the communication backbone in an nLight network. Fundamentally,
Bridges act as hubs by aggregating trafc from the connected downstream zones and
placing it onto the backbone. They also act as routers by forwarding information from
the backbone out to the applicable downstream zones.
The Bridge’s actual backbone link is formed by
connecting to another Bridge or a Gateway via
CAT-5 cabling through one of its RJ-45 ports.
Alternatively, with the Bridge’s -RF option, this link
can be made wirelessly using the ZigBee
®
mesh
networking protocol.
Finally, Bridges can combine system power from
zones that are net contributors of power (i.e.
those with downstream power packs and power
supplies) and distribute it to zones that are net consumers of power (i.e. those with only
sensors). Maximum power output per port is 40mA.
POWERING OPTIONS
There are two methods of powering an nLight Bridge:
LOCAL POWER SUPPLY (RECOMMENDED)
A 15-24 VDC or 24 VAC power supply can deliver power to the Bridge via the
terminal connections on the side of the unit. The PS-150 version power supply is
recommended, as it conveniently mounts through a knock-out on the side of the
junction box where the Bridge unit is mounted.
NETWORK POWERING (OPTIONAL)
A Bridge may also be powered over a CAT-5 connection from either an nLight power
supply or power pack. While the recommended method of network powering is
wiring an nPS-150 power supply directly to one of the Bridge’s RJ-45 ports, power
can also originate from nPP-16 power packs located elsewhere in the network.
