SSR-202
Wiegand Proximity Card Reader
Revision 1.2 - (June 29, 2009)
Quick Start Guide
Introduction
The SSR-202 is a proximity reader that can connect using the Wiegand wiring standard.
It can read various transponder cards at the industry standard frequency of 125 kHz, including
Hitag™ 1, Hitag™ 2 and HT4102.
It includes a tri-color LED for indication of the scanner status, and a Piezo buzzer to indicate a
successful card read.
This unit comes with a splash-proof back cover and can be mounted in any orientation using the
mounting screw holes.
This reader has been designed to be used with the following devices:
SDC-510 Single door controller.
SDC-520 Ethernet controller.
SEB-720 Remote IO board.
Any Wiegand standard controller.

Step 1: Set the reader to 26 bit or 34 bit Wiegand mode (See Fig 6)
The SSR-202 can be set into 26 bit, 34 bit or any bitlength Wiegand –this will affect the number
that is read from the proximity cards, so the correct setting must be applied and must be
standardised throughout the system to avoid problems.
To set 26 bit Wiegand format (24 bit data length) set the rotary dipswitch on the
back of the reader to ‘A’.
To set 34 bit Wiegand format (32 bit data length) set the rotary dipswitch on the
back of the reader to ‘B’.

Bit length settings
Note: The settings 0..9 are used for RS-485 mode and the C to F are reserved for other purposes
and should not be set in Wiegand mode.

Step 2: Connect the Wiegand lines (See Fig 5)
When in Wiegand mode the SSR-202 communicates with the Wiegand master device via six
signalling lines.
These lines can be broken into two groups:
The data lines (Data 0, Data 1 and Present). (The Present data line is not always required
and can normally be ignored.)
The indication lines (Red LED, Green LED and Buzzer)
Connect these lines ensuring that the correct cables are used.
Step 3: Connect the power (See Fig 5)
Connect the power lines to the reader making sure that correct polarity is observed.
Note: The power supply must be a 12 Volt DC power supply, capable of supplying 125mA.
When power is supplied to the reader the Piezo buzzer will sound briefly and the LED will begin
flashing blue.
