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.
Specifications:
Type of cards
* Any card of 64bit memory array used by H4001 CMOS
integrated circuit, by EM Microelectronic-H4100/4102 or
compatible.
Clock & Data ABA
(14/13 char), standard Wiegand 26 bits and
Wiegand 44 bits output format interface, photo coupling seclusion
OC gate output.
RS-422
Differencial outputs:
Connection distance
up to 300m.
TTL outputs:
up to 15m.
Note
: In case of reading errors, 1K pullup resistors can be
added to the Data and Clock outputs (yellow and white
wires).

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
