der and the 100R.
2. Check if any noise occurs in the communication cable between the exit reader and the
100R.
I. Check the exit reader output by checking the Wiegand communication cable with
a measuring instrument.
II. Check if any noise comes from the Wiegand communication cable with a measurin
g instrument.
If a noise exists in the Wiegand communication cable, enhance the GND signal by
using the shield wire and a spare wire of the cable as GND.
When using a measurement device such as an oscilloscope or multimeter, make su
re to consult with technician.
Check the Wiegand output by consulting the Exit Reader’s Manual. If the Wiegand
is not normal, replace the exit reader.
Do not try to extend the max transmission range for a Wiegand communication ca
ble or stabilize signals by using a repeater.
