LINK indicator is flashing or off
It is normal when LINK indicator is flashing (or off) at the time of the encoder powered on within one minute. After the encoder is successfully enabled, the LINK indicator is always on, otherwise off.
IF the LINK indicator is off, please check the network connection and device startup.
If the LINK indicator is always flashing, it may due to the failure of the device. How to detect the failure: you can try to Ping the IP address of THE encoder, or use the WEB browser to open the management interface of the encoder. If they can Ping through, or WEB access is normal, then the encoder is normal; otherwise the encoder is failure, please contact the manufacturer or reseller for repair.
