SF100 as a fingerprint reader, can support various Wiegand format outputs,
and can connect with access controllers of majority manufacturers on the
market. Wiegand output has two modes as follows:
The mode to output user number:
Wiegand outputs the fingerprint or
the user number after a successful card authentication, or the instruction
code after a failed authentication.
The mode to output card:
Wiegand outpu
ts the got card data, that is,
to output the card data as the original.
Note:
1) The recommended distance between device and access controller
should not be more than 90 meters (If a longer distance or an environment
with interference, please use the Wiegand signal extender).
2) Regardless of whether the device shares power supply with the access
controller, the device must share the ground with the access controller to
guarantee the stability of Wiegand signal.
3) Since SF100 and SF101 can not be used as readers, RLED, GLED, BEEP
are the idle terminals. In addition, SF100 has no Wiegand output, so 12V,
GND, WD0 and WD1 are also the idle terminals.
