DS-FDD5W is a new COFDM digital transmitter receiver with Frequency-division duplexing (FDD) technology, designed with dual-mode RF transceiver system which operate at different carrier frequencies ideal for long range communication in network solution. The FDD technique uses different frequency bands for video radio sending and receiving with no interference.

 

DS-FDD5W transceiver is implement of transparent IP Ethernet interface that able balance and stable high-speed data rate with 30Mbit/s each for uplink and downlink. Its ideal for broadcasting, public security system, emergency system, Police, military etc. required for long distance wireless private network links.

 

1. Feature:

2. Installatio

 

(1) Make sure the transceiver is off power

(2) Connect antenna

(3) Connect IP camera to Ethernet port in the transmitting end, connect laptop to Ethernet port in the receiving end.

(4) Power on transceiver

 

3. Parameter Setting

After the installation, power on transceiver, and it will show similar as below:

30Mbit/s FDD Digital Ethernet COFDM transceiver for long-distance required

 

 

Factory default parameters are as follows:

RX: Receiving end

Frequency:Freq=340MHz

Bandwidth:Band=4M

State: shows how strong the signal receiving (green bar means working normally, blue bar means not)

TX: Transmitting end

Frequency:Freq=650MHz

Bandwidth:Band=4M

RF power: Gain=-3dB=5W

 

Encryption:AES=0000 (means encryption off, user can set their password as they like)

Baud rate:BR=19200bps

 

Note: The parameters of TX and RX must be the same.

Press the(LEFT) 30Mbit/s FDD Digital Ethernet COFDM transceiver for long-distance requiredor (RIGHT)30Mbit/s FDD Digital Ethernet COFDM transceiver for long-distance requiredcan move the cursor to frequency, Band and AES, then press the menu30Mbit/s FDD Digital Ethernet COFDM transceiver for long-distance requiredto select one to modify. Using (UP) 30Mbit/s FDD Digital Ethernet COFDM transceiver for long-distance requiredor 30Mbit/s FDD Digital Ethernet COFDM transceiver for long-distance required (DOWN) to select increase or decrease. After finish it, then long press the (MENU) key 30Mbit/s FDD Digital Ethernet COFDM transceiver for long-distance required about 2 seconds, the system will automatically save the current setting parameters, and the LCD display constant and no longer flashing. The same actions to modify the bandwidth , Gain and AES and etc.

 

5. Attentions

5.1 Receiving siting

When choosing the receiving site, generally there should be a test for electromagnetic environment in case of wireless communication blink and electromagnetic interference. Make good use of the local environment resources, try to select the receiving site in higher altitude if possible.

 

5.2 Antenna installation

Avoid collision of feeders when install the antennas in case of force deformation, which will influence its performance. Install the antenna with manual instruction, like its direction and height. Make sure each connection is tight.

 

5.3 Lightning protection

If the system applied in frequent lightning areas, lightning protection should be adopted. Connect the ground to make sure the system has a good grounding effect. Besides, there should be the lightning protection for antenna. If there is already lightning protection facility, make sure the antenna and feeder is under the its protection.

If no lightning protection facility, here are 2 tips for lightning rod installation:

(1) Install a lightning rod in the horizontal distance of aprx. 1.5m from antenna. The top of lightning rod should be higher than antennas.

(2) Lightning rod should be a conical metal rod, which is longer than 0.5m. It should be better with anti-rusty, and good conductivity, such as copper. Lightning rod and antenna pole should connect with building ground.

(3) If its inconvenient to install lightning protection, there should be a lightning arrester between feeder and the device. And connect lightning arrester with building ground through a low resistance.

 

4. Warnings

(1) To avoid the system burnt, it must be connected antenna first, then power on.

(2) The system must power off, when remove antenna.

(3) Dont take apart the system without permission.
