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.
