monitor the network. The DIP Switch will disable or enable the LFP function.
LLCF (Link Loss Carry Forward) means when a device connected to the converter and the TP line loss the
link, the converter's fiber will disconnect the link of transmit. LLR (Link Loss Return) means when a device
connected to the converter and the fiber line loss the link, the converter's fiber will disconnect the link of
transmit.
LFP function is ON by default setting. If you are familiar with the network installation

the converter to make it take effect. Otherwise, please remain it in the default position.
