DIP-switch
The DIP-switch is used to configure operation mode for LLF (Link Lost
Forwarding)
and operation mode for UTP/Fiber port. The default value of
DIPswitch is OFF.
S/W No Status Description
1
ON UTP 100Mbps Full Duplex mode
OFF UTP Auto-Nego
2
ON Fiber in Half Duplex
OFF Fiber in Full Duplex
3
ON LLF Enable
OFF LLF Disable
4
ON Pure converter mode
OFF Switch Converter mode
Link Lost Forwarding (DIP-Switch 3):
When LLF is enable, it allows
UTP link failures to be reported to the fiber side and also allows 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 pure converter mode is
enabling (on), it operates with the minimum latency. The transmission flow
does not wait until entire frame is ready, but instead it forwards the
received data immediately after the data being received. And TP 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]
Please don’t change the DIP-switch setting when UTP or fiber port
is transmitting or receiving data. It may cause some data error. Besides, if
you change the DIP-switch setting, please power off the converter and
power on again to make the setting effective.
