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
per the following table. These numbers represent actual flat numbers for the digital
controller; they also correspond to the inputs on the BFD8 or BFD72.

SW7 is an 8 bit switch that is used to increase the addressing range. For each bit that is
switched ON add the corresponding value to the amount set by SW6. This allows flat
addresses up to 3210 to be set (6410 or higher with the jumper below).
