Selecting operating mode
Field changeable DIP switches allow all 94x and 97x readers to
operate in one of four distinct operating modes: Wiegand (4001),
F/2F, Supervised, and Silent Supervised.
In the unsupervised modes, the reader communicates with the
microcontroller over a unidirectional Wiegand or F/2F data link
that carries badge data only.
In the supervised modes, the reader communicates with the
microcontroller over a bidirectional F/2F data link, that carries
badge data, supervision messages, exit request and door switch
status, and microcontroller acknowledgments and commands.
Silent Supervised mode
is ideal for installations where no audible
or visual indication of communication loss with the
microcontroller is desired at the reader.
The table below shows the DIP switch settings for each of the
four operating modes.
