Transmitter Introduction
❖ The RF input port of the YUK1000L-T L-band optical transmitter can provide operating voltage to the Ku-band or C-band downconverter (satellite tuner LNB) connected outdoors through the panel control, and can complete the conversion of horizontal and vertical polarization received by satellite by this device.
❖ YUK1000L-T L-band optical transmitter can be set to automatic or manual working mode. In the automatic working mode, the gain of the whole machine can be automatically adjusted according to the input signal level, so that the laser excitation level always works within the optimal range. Manual working mode allows users to customize the laser excitation level (non-professional users please use the automatic working mode directly).
❖ The front panel of YUK1000L-T L-band optical transmitter provides an input signal monitoring port (main signal -20dB)
❖ YUK1000L-T L-band optical transmitter can provide one loop-out signal interface (optional).
❖ YUK1000L-T L-band optical transmitter has a complete RJ45 network interface, which can be connected to the network management through SNMP or TCP/IP protocol (optional).
❖ YUK1000L-T L-band optical transmitter is equipped with high-quality power supply, and optional dual power supply to improve system reliability.
❖ YUK1000L-T L-band optical transmitter has 10MHz signal transmission version (optional).
Operation Mode
Depending on the actual application, the user can choose from several working modes. These modes can be divided into automatic switching control or manual switching control.
Auto Switch Mode
In the automatic switching mode, the switching level threshold of each channel can be set independently. The main and auxiliary channels can be set, and it can be set to allow or not allow the main channel to automatically switch back to the main channel after the signal is restored.
Manual Switch Mode
In manual mode, the working channel can be manually set according to user’s needs, and can be forced to switch to another channel.
Mode settings are stored in the module's non-volatile memory. When powered up, the module will revert to the operating mode settings it was in before the last power outage. When the power is turned off, the A channel of the device can transmit signals normally, but other functions are unavailable.
Fast Switching Function
The device has a fast switching function. Press and hold the corresponding button for 3 seconds to perform a fast channel switching function.
