5. The meaning of the product status light

Power light PWR (green)

When the PWR light is on, it means the device is powered on.

Synchronization light SYNC (green)

In the unsynchronized state, the light flashes. After synchronization, the light is always on.

Network port lights LAN1, 2 (green)

When the network port has data to send and receive, the network port light flashes.

Receive signal energy light (RSSI 3 green lights)

The more the energy lights are on, the stronger the signal-receiving strength is.

The RSSI light represents the received signal strength
The number of RSSI energy lights on	Received energy dBm
3 RSSI lights are all on	-45dBm or so
2 RSSI lights are on	-80dBm or so
1 RSSI light is on	-95dBm or so

module type	model	W1400-33-SMA series indicator status
		PWR light	SYNC lights	LAN 12 lights	RSSI 123 lights
host	not synchronized	Always on when powered on	flashing	Data sending and receiving, flashing	wipe out
host	after synchronization	Always on when powered on	always on	Data sending and receiving, flashing	Proportional to received signal strength
from	not synchronized	Always on when powered on	flashing	Data sending and receiving, flashing	search status
from	after synchronization	Always on when powered on	always on	Data sending and receiving, flashing	Proportional to received signal strength

When the master and slave devices are not successfully paired, the power PWR lights of the master and slave devices are always on, the SYNC lights are flashing, and the RSSI lights of the master device are all off. The RSSI of the slave device will always be in the search state. After the master and slave are synchronized, the SYNC light of the master and slave is always on. The master and slave RSSI lights show the received signal energy strength. When the network port is sending and receiving data, the corresponding LAN1 and 2 lights of the master and slave devices will flash correspondingly.
