2. Installation & Connection
The reader must be installed and connected correctly before operating. First you sh ould connect power
supply and antenna before connecting PC or controller.
2.1 Installation & Power Supply
The reader can be simply installed. Please adjust the fixture to a suitable angle according to your
application.
The maxmium distance between the reader and host varys from data port types. The reliable
communication distance is 10m for RS232, 5m for USB, 15m for Wiegand, 100m for LAN, and 1.0KM for
RS485. Exceeding the above distances is not suggested.
The power input of this reader is 12V DC. An AC to DC adaptor is offered. Plug the adaptor into DC
connector of reader before operating. If the reader makes a sound of a long B eep, the power input is
normal.
2.2 Connect to PC & Controller
The reader can be connected to PC by RS232, USB(need a RS232 T o USB Converter). (For detail
please see Part 4. Communication Port.)
The reader can be connected to controller by RS485 or WIEGAND. It can realize input / output operation
and response to outer trigger or GPIO port(not lead out by default). (For detail please see Part 4.
Communication Port.)

3. Working Mode
The reader can identify working modes automatically and make corresponding response.
3.1 Master-Slave Mode
Under Master-Slave working mode, readers must be controlled by host machine (PC or controller). It
receives the command from host, executing read/write actions on tags, and responsing the data to the
host. Before receiving command from host, reader will stay idle.
We provide SDK software package for reader. This kit package includes Serial Port Communication
Protocol, API functions set and Demo sample program. API functions set and Demo sample program is
for PC to communicate with reader, while Serial Port Communication Protocol is for Controller to
communicate with reader.
3.2 Trigger/Automatic Mode
Under Trgger/Automatic working mode, reader will detect tag automatically in periodical time. After that, it
will response data to the host. In this mode reader does not need to wait command from the host.

4. Communication Port
The reader has kinds of communication ports. It can communicate with PC or controller that has standard
RS232,RS485 or Wiegand port. The communication ports of the reader include:
Port Name Port Type Port Qty. Application
TRIGGER IN 1 Pcs Connect Reader to outer Relay
RS-485 A+,B- 1 Group Connect Reader to Controller
WIEGAND D0,D1 1 Group Connect Reader to Controller
RS-232 DB9 Female Port 1 Pcs Connect Reader to PC
LAN RJ45 Port 1 Pcs Connect Reader to PC/HUB
GPIO GPI, GPO Optional, not lead out by default General Input/Output

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 b etween reader and co ntroller.
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: RS485A+(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.
4.2 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 suggeste d connecting method is illustrated
below:

GPIO
Note: By default we do not give GPIO, user may ask us to customize them if needed.
In GPIO connection, you should connect GPO(Output) and GPI(Input) to the outer equipment. T he GPO
could be connected to outer equipment(eg. Relay) to drive the barrier or light.

5. FAQ
The frequent asked questions and the resolutions are listed below:
Failure Possible Reason Solution
Tag unreadable Tag is too far from antenna Move the tag close to antenna
Tag direction does not match the antenna
polarization
Please face tag to antenna, and keep the correct
polarization
Tag has been damaged Change a new tag
Power does not work Poor contact for power plug Check the power supply, use the correct power
