FMUSER Digital Studio to Transmitter Link (STL) Installation and Configuration
First, preparation before testing
After receiving the Fmuser DSTL system, first of all we need test if all the devices work well and confirme that the system works properly before it can be installed in the tower and studio.
To test a DSTL system, we need: two plugs, a video input source, a display, and a DSTL system.
Second , Connect All the Devices
Now it is Fmuser's DSTL system, which is mainly used to transmit the studio programs to the transmitter in the tower.
It consists mainly of two parts: the studio parts and tower transmitting parts.
The studio side is mainly composed of video sources, switches, encoders, bridges and antennas.
The tower side is mainly composed of an antenna, a bridge, a switch, a decoder and a transmitter. Since we are testing now, we replaced the transmitter with a display.
Fmuser's DSTL system is made up of these devices.
Third, Interpretation of the principle of the studio system.
Now, I will explain the principle and connection method of the DSTL system studio side.
First input the video source into our encoder.
The encoder can be input with HDMI, RCA and SDI.
The encoder encodes the received video (analog to digital) and transmits it to the switch via a network cable.
The switch aggregates all the signals and transmits the signals to the bridge through the network cable.
The bridge modulates the signal (wired to wireless) and sends the signal through the antenna to the tower side.
The network cable used, we are classified, the brown network cable is the data cable; the blue network cable is the management cable;
There is also our POE power supply, his POE port is connected to the bridge, and the LAN port is connected to the switcher.
What I said just now is the system principle and connection method of the studio terminal in Fmuser's DSTL system.
Fourth, Explanation of the principle of the transmitter broadcasting tower side.
This side is the transmitter end of Fmuser's DSTL system. Let me talk about the system principle and connection method of this end.
First of all, use the receiving antenna to receive the signal from the studio side, and transmits the signal to the bridge.
The bridge modulates the received signal (wireless to wired) and transmits it to the switcher.
The switcher then transmits the signal to the decoder.
The decoder decodes the received signal (digital to analog) and transmits it to the transmitter. The test transmitter is now replaced by a display.
The decoder has HDMI, RCA and SDI output.
As with the studio end, the blue cable is the network management cable, and the brown network cable is the data line.
The POE power supply is also a POE port connection bridge, and the LAN port is connected to the switcher.
What I said just now is the system principle and connection method of the transmitter terminal of Fmuser's DSTL system.
Fifth, the state after installation
After we connect Fmuser's DSTL system, how do we confirm that the system works?
First we transfer the video from a video source to the encoder.
Then we use the decoder to output the video to the display.
Finally, check whether if the display can play the video normally, if it is clear or freezing.
If there are no problems, then it proves that the DSTL system is working properly.
