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 t
he 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’.

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.
