Jumper Blocks
Two sets of jumper blocks are provided in
the upper middle, and lower middle of the
board. They allow the inputs and outputs to
be jumped together.
The silk-screening by the jumpers indicates
which points are connected to which pins.
Putting a jumper block on two horizontally
adjacent pins is the same as putting a jumper
from the output point to the same numbered
input point.
For example, a jumper placed on the pins
labeled “3” would jump input point 3 to
output point 3.
WARNING: When an input
and output are jumped
together, always connect
the field wiring to the
OUTPUT terminal. Do NOT
connect the field wiring to
the Input terminal, as this
could overload the wiring on
the board.
Inputs and outputs are normally connected
together on the car and hall call buttons and
lights.
NOTE: If a board is replaced, the
board must be set up with the SAME
JUMPERS as the board it was
replacing.
