3.2 Operation
3.2.1 Fingerprint scan method
To take HD fingerprint image, , finger should be close to touch fingerprint sensor and refer to
below picture and use correct method to scan the fingerprint:
Remark: Pic a and Pic b as the right way, Pic a as face, Pic b as side. Pic c, Pic d and Pic e
as wrong way.
Put the finger and wait more than 0.5s! One user can have three fingerprints, here advice
one user register 1 or 2 fingerprints.
3.2.2 Simply operation method
Connect the device by RS485 with the computer, use software to manage, and do the
following operations:
3.2.2.1 Register User
Using software to register user information, include User ID, Fingerprint Index No. (No. in
the registered fingerprint database), Card No., backup password;
3.2.2.2 Register fingerprint
Using software to register, maximum fingerprint eigenvalue as 1664 bytes.
3.2.2.3 Register fingerprint
Using software to register the registered fingerprint, if not register in the device first.
3.2.2.4 Standalone mode
Input fingerprint, swipe card or press keypad, then output the set Wiegand format date.
3.2.2.5 Swipe card with fingerprint
Swipe card first, scan the fingerprint in the 10s of the associated fingerprint, if input
succeed, will output the User ID by the set Wiegand input format. If the device is as Out
direction, output Wiegand 29 only. Press button to output the keypad signal.
3.2.2.6 ID with fingerprint
Input User and press # as the end, input the fingerprint in 10s, if succeed, will output the
User ID by the set Wiegand input format. If the device is as Out direction, output Wiegand 29
only. Swipe card to output the associated Card No.

3.2.2.7 ID with password
Input User and press # as the end, input the user password in 10s, if succeed, will output
the User ID by the set Wiegand input format. If the device is as Out direction, output Wiegand
29 only. Swipe card to output the associated Card No.
3.2.2.8 Swipe card with password
Input User and press # as the end, input the user password in 10s, if succeed, will
output the User ID by the set Wiegand input format. If the device is as Out direction, output
Wiegand 29 only. Input fingerprint to output the associated User ID
3.2.2.9 Fingerprint with password
Input Fingerprint, input the user password and press # as the end in 10s, if succeed,
will output the User ID by the set Wiegand input format. If the device is as Out direction, output
Wiegand 29 only. Swipe card to output the associated Card No.
3.2.2.10 Change Device ID
Using ID as 0 to connect the device with the software, then use the software to change the
ID, available range is from 1 to 254.

When have alarm (door switch, infrared) audion power on, relay action.
Remark: OC door alarm output, need addition a outer relay and a DC12V power supply.
3.3.3 RS485 connections
Attentions:
1. RS485 communication suggests use STP cable had better multi-core
STP;
2. Use a twin-STP cable to be signal cable;
RS485 connection:
1. A, B terminals must be welded well;
2. Must use CAT-5 STP;

6. Installation Defines
Attentions:
Fully consider easy for repair and maintains
Location should avoid choose high temperature site
Device can’t under straight sunlight
Device can’t be shower bath
Before installation please testing device
6.1 Installation tools and materials
Installation tools:
Electric drill, strike drill, cross screwdriver, angle grinder, wire-cutter, wire strippers, press
line pliers, the hammer, etc.
Installation material:
PVC cable tank or cable tube, screws, installation hanger, etc
6.2 Installation Steps
6.2.1 Installation station selection
Fingerprint reader along to high technical precision instrument, the installation place will
affect the products life-span and working performance, refer to above notice to choose the best
place for use.
6.2.2 Installation
When install the fingerprint reader, pay attention to the screwdriver and other edge tools
don’t destroy the shell, avoid any damage to keep good appearance.
6.2.2.1 installation wall manage
Before installation, must manage the wall, find the logical height-ness (suggest 1.4 to
1.5m), and based on the hanger (accessory of fingerprint reader) size to drill the holes on the
wall to fix the fingerprint reader, and wiring the reader, the hanger size refers to below picture:

6.2.2.2 Cables connection
Connection the cables according to the definition, and weld the cable joint to keep it
fastness, and use the pyrocondensation tube to packing it well.
Take care below points:
1) The power supply cable must connect correct, red cable to positive, black cable to
negative, can’t be in reverse.
2) Fingerprint reader Wiegand output signal cables, connect the Wiegand of the controller
for transferring fingerprint ID to controller;
3) Power supply cables suggest to use more than 0.5 square mm, signal cables use
AWG16#-AWG24# cables, much better to use shielded wire pipe to make the cables low
down the possibility of the outside interferences.
