Power indicator light, always on when powered on, off when no power

1. 1 to many (including 1 to 1) - bidirectional (when the devices have the same number of channels): As long as one slave is successfully connected to the master, the master's LINK indicator is always on; after the slave is successfully connected to the master, the slave's LINK indicator is always on;

2. 1 to many - two-way (different number of channels, each channel of the host is independently controlled by the slave): the number of times the host's LINK indicator flashes depends on the number of devices connected (cycle: 300ms, after flashing, it turns off for 1s, and then flashes again). For example: if 3 devices are connected, the LINK indicator flashes 3 times according to the cycle, then turns off for 1s and flashes again;
