Product installation

connected relation
In the application system, the connection relationship between the reader, microwave antenna, electronic tag, and controller (or PC) is shown in the following figure:

Installation Procedure
When installing the equipment, follow the following steps:

Install reader
The installation of the reader should pay attention to the following matters:

1. The VF-747P reader has no special waterproof and dustproof treatment, and its working temperature range is: -20℃~+40℃; therefore, it is more suitable for working in an indoor environment. If you want to install it outdoors, you must put the reader and power converter in the protective box. The protective box is required to have the functions of rainproof, dustproof, heat preservation and heat insulation to provide a better working environment for the reader.
2. The RF line distance between the position where the reader is placed and the antenna should not exceed 10 meters (3 meters is better).
3. The maximum distance of reliable communication between the reader and the controller varies with the data interface

When using the RJ45 interface to communicate: Support 10M/100M transmission rate, using a network cable, it is recommended that the transmission distance should not be greater than 50 meters.
When using RS485 interface communication: the two wires RS485+ (brown) and RS485- (blue) on the reader should be connected to the corresponding two pins of the controller. It is recommended that the transmission distance should not be greater than 80 meters.
For RS232 interface: You can use the supporting cable to directly connect to the PC. It is recommended that the transmission distance should not be greater than 10 meters.

The connection diagram is shown in the figure below:

Install antenna
The antenna installation needs to consider factors such as position, height and angle to meet the following application requirements:

1. Ensure that the antenna beam range can cover the range of reliable reading of electronic tags.
2. Ensure that the length of the RF cable from the antenna to the reader is not more than 10 meters, preferably not more than 3 meters.
3. Depending on the specific application, the antenna can be installed horizontally top-mounted (gantry) or vertical side-mounted (post), but the polarization direction of the antenna must be consistent with the polarization direction of the electronic tag.

Connect the antenna and reader
The VF-747P reader provides 4 SMA male RF interfaces, which require low-loss coaxial cables to be connected to the antenna. Since the longer the cable length, the greater the attenuation of the high-frequency signal, the shorter the cable length is required for the application, the better. Increasing the length of the cable or using an ordinary cable will affect the reading and writing distance of the reader.
When the connection distance between the antenna and the reader is within 3 meters, it is recommended to use the1/2 feeder; when the distance is more than 3 meters, the 7/8 feeder. The cable length must not exceed 10 meters.

The cable connector is connected with the antenna and the reader terminal
Should be tightened. After the cable connector is tightened, the cable connector should be sealed by heating and shrinking or tightening with tape to protect the cable connector.
WIFI/4G connection port and antenna (this port is optional)

Note: It is not recommended to use ordinary cables to connect the antenna; it is not recommended to assemble the cable connector by yourself.

Connect the reader and the host computer
The VF-747P reader can be connected to the host computer (or PC) through either of the RS232 or RJ45 ports to receive commands and send data.

1. Connect through the RJ45 port (as shown in P 2-6-1)： The reader is directly connected to the PC, as shown in the figure below, the wiring arrangement is as follows: Pin 1 of the RJ45 port of the reader is connected to pin 3 of the RJ45 port of the PC, pin 3 of the RJ45 port of the reader is connected to pin 1 of the RJ45 port of the PC, pin 2 of the RJ45 port of the reader is connected to pin 6 of the RJ45 port of the PC , Pin 6 of the RJ45 port of the reader is connected to pin 2 of the RJ45 port of the PC, and the other pins are connected correspondingly. The reader and the PC are connected through the Hub, using a straight-through connection line.
2. Connection through RS232 port
   The RS232 port can be directly connected to the PC with the supporting cable. The length of the RS232 port connection line in the project should be less than 10 meters. The connection diagram is shown in P 3-6-3.

Connecting power Supplies
The VF-747P reader/writer adopts +12/3A DC power supply. Along with the reader, our company provides an AC/DC converter that meets this requirement. The power connection method is as follows:

1. Check and confirm whether the voltage and working frequency of the AC power supply meet the requirements of: AC100～240V/50Hz;
2. Insert the DC output plug of the power converter into the +12V DC input port of the reader
3. Insert or connect the 220V AC power input line of the converter to the AC power supply line.
4. The red indicator light of the power supply of the reader should be on, indicating that the power input is normal..

The equipment alignment
The key of device alignment is to adjust the height, direction Angle and inclination of the antenna so that the reader can read the electronic tags within the desired range. The debugging method is:

1. Turn on the power of the reader, set the reader to the timing working mode, close the parameter setting program and disconnect the connection with the PC.

2. Turn off the power of the reader and then turn it on again, the reader will automatically enter the timing working state.

3. Because the material of the identified object is different, the required label is also different. Therefore, when debugging, the electronic label should be affixed to the object with the same material as the surface of the identified object, and back and forth within the range where the label is expected to be read. Move objects. If the reader can read the electronic label correctly, the built-in buzzer will sound and the RF
   The LED flashes.

4. Carefully adjust the height and angle of the antenna to make the reading range the best.

Note: The reader only radiates microwave power when reading and writing tags. At this time, the installation and debugging personnel should be at least 70cm away from the antenna to meet the requirements of the US FCC for the human body.
Exposure to the maximum allowable radio frequency (RF) radiation requirements.

Attach label
In the application process of radio frequency identification system, labeling is often done. The issues that need to be paid attention to when labeling are:

1. Use the adhesive glue recommended by the manufacturer.
2. For labels applied to metal surfaces, special adhesive glue should be used.
3. The position of the label on the surface of the object must also undergo field tests to ensure the best read and write effect.
