DCU State Indicator Light

Power--When the light is red and normally on,it means the CPU of the DCU start working but still not connect with with server.When the light is blinking, it means the DCU start working and is connected to the server ;
Alarm--When alarm ,the light is red and blinking
On-line--The light is on, it means the DCU succeed in connecting server,otherwise the connecting is failing;
Signal strength--When the light is green, it means the signal is strong, red means signal weak and when the red and green is on at the same time, it means the signal is medium;
Link--Ethernet state, when the light is on(green), it means the ethernet connecting succeed;
Data--Ethernet data state, when the light is on(red),it means there is data exchange via ethernet;
Long-distance--Long-distance communication state, red blinking means the DCU is receiving the remote data, green blinking means the DCU is sending the remote data.
Local--local communication state, red blinking means the DCU is receiving the local data, green blinking means the DCU is sending the local data.
 

4G communication module state indicator light

4G communication module light
Power--power light, when the light is on, means the 4G module working; when the light is off, means module stop working;
NET--Network state, when the light is on, the 4G module is working well.
