Synel PRX-20 User Manual

Introduction

PRX-20 card reader is a non-contact high performance card
reader with ABA (14 & 13 char), standard Wiegand 26 bits
and Wiegand 44 bits output format. These units are mainly
used as card reading support for access controllers and are
characterized by their smart and elegant appearance, simple
wiring and stable performance.

Note:
1. Se1_EX=1 or Se2_EX=1 is a free wire, not connected to
any wires.
2. Se1_EX=0 or Se2_EX=0 is a wire connected with GND.

Wiegand Output Format - Further details

D0 and D1 output "0" and "1" respectively.
When outputting "0", D0 experiences a negative pulse and
when outputting "1", D1 experiences a negative pulse.
See the following diagram displaying a negative pulse width
of TP=100+10 microsecond; with a repetition period of
TW=1000+100 microsecond and 1 microsecond=1/1000000
a second.
In the following diagram C and O stand for 0 or 1.
E: even check code; O: odd check code
