OVERVIEW
The Presco™ PRX Proximity Reader by Nidac is an advanced,
self contained RFID (Radio Frequency IDentification)
contactless reader. It is capable of interfacing to either a
Wiegand input control panel or to Nidac’s new range of
Presco™ PAC decoders.
The mullion (or architrave) styling makes the PRX suitable for
door frame mounting as well as other mounting positions.
OPERATION
Connected to a Presco™ PAC decoder
The LED on the reader is red when ready to read a Presco™
prox card. When a card is presented to the front of the reader
the LED momentarily turns orange to indicate that the PRX has
read it. The code is then transmitted to the PAC decoder.
If the card is valid the PRX will respond with 1 or 2 short beeps
and the LED will change to green (provided the blue wire is
connected as shown in the wiring diagram) for the time the ELC
relay is active (door is released).
If the card is invalid the PRX will respond with a “blarp” (long
beep) and the LED will remain red.
Connected to a Wiegand controller
The LED on the reader is red when ready to read a Presco™
prox card. When a card is presented to the front of the reader
the LED momentarily turns orange and the internal buzzer gives
a short beep to indicate that the PRX has read it. The code is
then transmitted to the Wiegand controller.
The LED can be made to change colour to green by the
controller by applying +5 to 15 Volts D.C. to the blue wire.

WIRING DIAGRAMS
Connecting the PRX to a Presco™ PAC decoder
Note that the Green, Yellow and Drain wires on the PRX are not
connected when it is used with a PAC decoder.
* Use a 200mA inline fuse to protect the power supply from short
circuiting if PRX wires are tampered with. This is particularly
important when using fail safe (power to lock) locking
mechanisms.
Programming Prox cards & tags into a PAC decoder
To program a proximity card or tag into a PAC decoder follow
the same steps as shown in the decoder manual for
programming a new user code. When it comes to the stage to
enter the user code simply present the card or tag to the PRX
that is connected to the same input as the programming keypad,
7
or alternatively enter the 9 digit code for the proximity card, note
that this code may contain star (*) and hash (#) symbols and that
leading zeroes (0) need to be entered.
Example
This example uses a PAC1 decoder programming a momentary
operation proximity card or tag into memory location 001.
1. Put the PAC1 into program mode using the management
code or button on the PAC1.
2. Open the memory location in which the Prox card is to be
stored. * 001 1 E
3. Present the proximity card or tag to the PRX.
4. Take the decoder out of program mode.

Connecting the PRX to a Wiegand controller
Note that the White wire is connected to GND (Black wire) at the
PRX, but the Drain is connected to GND at the Wiegand
controller.
The Blue wire controls the LED on the PRX. When a high
voltage (+5 to 15V D.C.) is applied to this wire the LED will
change to Green. This is normally connected to the switched
positive side of the Electronic door release mechanism.
* If the controller does not provide a fused output for readers use
a 200mA inline fuse to protect the power supply from short
circuiting if PRX wires are tampered with.
