LED Wiegand Bit Counters
The CA150 control board has LED Wiegand bit counters – 10s and 1s – to indicate the card’s binary bits. You
must be able to observe the control board to do this procedure. To verify the binary bits, present the card or
tag at the reader and count the number of times each LED blinks:
 10s counts the 1
st
binary digit
 1s counts the 2
nd
binary digit
Example
If the 10s LED blinks 3 times and the 1s LED blinks 6 times, the card has 36 binary bits (36-bit Wiegand
card).
