The Interface is a small, narrow,
circuit board covered in heat shrink.
It can be located behind the
elevator cab reader, where the
reader cable connections are
made.
Elevator Isolator board Jumper positions
for Normal reader distance: 500 feet
(152 meters) - connect to normal
distance isolator board reader
connections (see figures 8 and 9).
RS485 Jumper positions for
recommended maximum distance of
2000 feet (610 meters) - connect to
these isolator board terminal blocks 9
and 7.
installed on
Elevator
Cab roof.
NOTE: Maximum length of cable allowed for 485 operation may be lower due to cable
capacitance characteristics, card reader technology and manufacturer.

IMPORTANT NOTE:
Set reader voltage jumper to

Put a 2.2K ohm resistor
between normal reader pos.
voltage and green LED inputs.
For RS485 operation.
If interference is encountered with 485 communications, terminate all A and B connections at both ends of the reader
cable with 150 ohm resistors, P/N 750-2465 (5%).
