2.4.3 External RF cable description
Picture 2-10 RF cable schematic chart
The connector between RF cable & reader is TNC male, the connector between RF cable &
antenna is SMA male connector (depending on antenna connector as well). Try to keep the
cable length within 5meters, impedance 50Ω, the insertion loss less than 2dB. Of course, you can
choose a high-performance cable, appropriately increase the length, but keep the insertion loss
less than 2dB.
Note: Too long RF cable or cable poor connection will cause high signal attenuation & poor
reader performance.
2.4.4 External antenna description (optional)
This reader has a integrated circular antenna. User can also connect one more external antenna.
It is recommended to use the external antenna provided by our company.

3. Installing
3.1 Precautions
In order to ensure normal and stable operation of the equipment and your personal and
property safety, before installing CL7206B reader device, please carefully read the following
notes.
1> Firstly check whether the outlet is connected to earth ground, and check if the local
power supply voltage meet reader voltage requirements.
2> Check if the device is connected tightly and the metal house of the device is connected
with ground.
3> pay attention to the network cable and serial cable type selection and length restrictions;
4> When installing multiple readers, pay attention to reader antenna display way & the
minimum distance between the antennas , avoid the situation that interference may affect the
reader's performance;
5> please test & ensure the reader can work normally before using it.
3.2 Installation conditions
Before installing the reader, please check carefully whether the product is intact, the accessories
are complete.
3.3 Device connection
3.3.1 Connected to power adapter
☆ Connect power adapter to AC power socket, and the other end to reader power
support interface.
☆ After the circuit is connected, wait for about 20seconds, reader makes two alarming

sound and enter into initialization state, after initialization is finished, reader enter into
standby mode.
3.3.2 Connect an external antenna and RF cable
☆ The reader housing has a TNC-type coaxial connector for connecting an external
antenna. Please use low-loss RF cable. The connection between the joints should be tightened
(for outdoor installation joints please pay attention to water).
☆ reader external antenna is usually placed at outdoor. Its beam coverage is the effective
reading range (try to avoid other objects occlusion).
☆ according to onsite situation, the reader antenna angle should be adjusted to the best
condition till when the reading performance reaches its best after testing.
3.3.2 Connected with PC
☆ RS-232 interface is used for short-range communication (less than 10m), can be
connected to a PC via the serial port connector for communication.
☆ RJ45 Ethernet port is used for longer range communications (less than 80m), can use
extended network cable to connect the PC and RJ45 interface.
3.4 How to install the reader
According to field situation, preliminarily confirm the reading range. According to field
read/write testing result, adjust antenna (rotation) angle, to make the reading performance
reaches its best. Finally, Fixed the device and the tilt (rotation) angle.
3.5 Installation steps
3.5.1 Vertical pole installation
1> Align the L-shaped mounting bracket against the holes on bottom of reader housing,
