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.
