AT-IMC100T/SCSM and AT-IMC100T/SCMM Fast Ethernet Industrial Media Converters
2.6 DIP-Switch
Table 2-2: DIP-Switch Status Description
Link Lose Forwarding (DIP-Switch 2)
: When LLF enabled, it allows UTP link failures to be reported to the fiber side and
also allows Fiber link failures to be reported to the UTP side. Therefore, a link fault pass-through feature is provided in both
UTP and Fiber side.
Media mode (DIP-Switch 4)
: When media mode is enabled (ON), it operates with the minimum latency. The transmis-
sion 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 switching mode (OFF), the con-
verter function is the same as a 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.
