This product herewith complies with requirements of EMC directive 2014/30/EU, Radio Equipment Directive 2014/53/EU. In addition it complies with RoHS2 directive EN50581:2012 and RoHS3 Directive 2015/863/EU.
11. SAFETY PRECAUTIONS
Do not install the device in a place subject to direct sun light without protective cover.
Do not install the device and cabling close to a source of strong electro-magnetic fields like radio-transmitting antenna.
Do not place the device near or above heating equipments.
If cleaning, do not spray or splash water or other cleaning liquids but wipe it out with smooth cloth or towel.
Do not let children touch the device without supervision.
Note that if the sensor is cleaned by detergent, benzene or thinner, the surface will be damaged and the fingerprint can’t be entered.
10. WIEGAND PROTOCOL DESCRIPTION
The data is sent over the lines DATA 0 for the logic “0” and DATA 1 for the logic “1”. Both lines use inverted logic, meaning that a pulse low on
DATA 0 indicates a “0” and a pulse low on DATA 1 indicates a “1”.When the lines are high, no data is being sent. Only 1 of the 2 lines ( DATA 0 /
DATA 1 ) can pulse at the same time.
Example:
data 0010....
Data bit 0 = approximately 100 us (microseconds)
Data bit 1 = approximately 100 us (microseconds)
Time between two data bits: approximately 1 ms (millisecond). Both data lines (D0 and D1) are high.
Description for the 26 bits Wiegand format
Each data block consists of a first parity bit P1, a fixed 8 bits header, 16 bits of user code and a 2nd parity bit P2. Such a data block is
shown bellow:
Parity bit (bit 1) + 8 bits 16 bits user code = 2 bytes + Parity bit (bit 26)
P1
XXXXXXXX
XXXX
YYYY YYYYYYYY
P2
Example:
170
31527
1
1 0 1 0 1 0 1 0
0 1 1 1
1 0 1 1 0 0 1 0 0 1 1 1
0
Note:
Parity bits are calculated as follows:
P1 = even parity calculated over the bits 2 to 13 (
X
)
P2 = odd parity calculated over the bits 14 to 25 (
Y
)
