BUS End-of-Line Resistors – Jumper Locations
NOTE: Do not confuse this End-of-Line Resistor with the End-of Line resistor required at the
end of a coax cable entering the KBS3-2. See page 9 for more information.
For proper system operation, the last video
monitor on a BUS riser as well as the last
camera on a run must have an End-of-Line
Resistors.
These resistors are built in to the printed
circuit boards and can be connected by
installing the jumper on the two pins labeled
J1.
Usually these jumpers are supplied on all the
monitors and camera boards and must be
removed if the unit is not the last camera or
monitor connected to the BUS line.
If there is only one camera used or one
monitor used, the End-of-Line resistors must
still be used.
The Chart to the left shows the locations of
the J1 pins on the different circuit boards.
