Card Reader: Wiegand D0 or
Magnetic Stripe Data Input
Use these terminals to connect to an
external card reader to supply user IDs
instead of having users enter their IDs
using the reader keypad.
(These terminals aren’t needed if your
reader has a built-in card-reader.)

Tamper switch output
Use this terminal to connect to a
tamper alarm. A signal goes through
this connection if the reader is tipped,
indicating that someone may be
tampering with the reader.
7
External bell input
These terminals let you connect output
wires from your access control panel
so your access control panel can
control the bell (beeper) and red/green/
amber LED’s on the reader. For input
here to make a difference, the Beeper/
LED settings on the Setup menu must
be set to respond to external input; see
page 41.

Reader/host network Tx: RS-485
wiring or RS-232 wiring
Use these terminals to network with
other FingerKey readers through either
RS-485 wiring or RS-232 wiring. (RS-

reader to a host computer; usually you
will use RS-485.)
