BRI-Hub
TECHNICAL: 0118 931 2233
If a BRI needs to be made available in several rooms, it used to be necessary to install a bus
from the server room through all rooms. (See picture ‘old’). Now star wiring can be used with
BRI-Hub, which comes to use also for telephone and local area networks (see picture 'with
BRI-Hub').
Options
BRI-Hub
This option derives its power from the power supply provided.
BRI-Hub S
This option derives power from the S-Bus and uses an internal DC-DC converter to adapt the
voltage to power itself – no external power supply is required. This option is available as a
special request from Black Box.
Both of the above options can be used in conjunction with the Phantom Feed, a device used
to provide power on each of the hub’s S interfaces.
