BSC4 Video Controller Settings
Jumper settings
The “Video Gain” jumper on video controllers should always be set to “0” unless directed
by Bell System Technical. This jumper is only required on some systems with very long
camera to apartment station cable runs well in excess of 150m. Inappropriate use of this
jumper with short runs will cause picture problems.
The “Video Terminator” jumper must be set to OFF on all but the furthest Video Controller
from the Door Controller(s), this one must be set to ON.
Switch settings
SW6 is a rotary 16 position switch which sets the apartment station (Phone) addresses as
