Connect to PC
The reader can be connected to PC by RS232 or LAN.
RS232
The reader has a DB9 RS232 port which is usually connected to PC for communication. Directly connect
RS232 of reader to the COM port of PC with DB9 Female cable. The inner connecting relationship is
illustrated below:
4.1
Connect to Controller
The reader can be connected to controller by RS485 or WIEGAND.
RS485
The reader has a RS485 connector, which is usually used for connection between reader and controller.
It can be intergrated to RS485 network or connected to PC through a converter. RS485 should be a twist
masked cable, with 1000m of reliable communication distance. RS485 cable consists of two difference
signal wires: (
A+
) and RS485B-(
B-
).
Wiegand
The reader has a Wiegand connector, which is usually used for connection between reader and controller.
Wiegand should be a twist masked cable, within 10m of reliable communication distance. Wiegand cable
consists of three signal wires: Data0(
D0
), Data1(
D1
) and Ground(
GND
). Please make sure the good
connection to the ground.

Connect to Trigger & GPIO
The reader can response outer trigger. It can realize input/output by GPIO, too.
Trigger
In Trigger connection, you should touch
IN
to
GND
by outer trigger. For example, you may add a relay to
realize a trigger from ground sensor or key-pressing. The suggested connecting method is illustrated
below:
