Link Lost Forwarding (DIP-Switch 3): When LLF is enabled, it allows UTP link failures to be reported
to the fiber side and also allows a fiber link failure to be reported to the UTP side. Therefore, a link
loss forward feature is provided in both UTP and fiber side.
Pure Converter mode (DIP-Switch 4): When the pure converter mode is enabled (on), it operates
with minimal latency. The transmission flow does not wait until the entire frame is ready, but
instead it forwards the received data immediately after the data has been received. The UTP port
should be forced at 100M in this application. When DIP-Switch is in Switch Converter mode (off),
the converter function is same as Switch Hub.
Note: Do not change the DIP-switch setting when UTP or fiber port is transmitting or receiving
data. It may cause some data errors. If you change the DIP-switch setting, please power off
the converter and power it on again to make the setting effective.
