Pin 2 Off/On TP Speed 100M/10M
Pin 3 Off/On TP Duplex Full / Half
Pin 4 Off/On Link-Cross-Check Disable/Enable
Default set OFF from PIN 1 to PIN 4
Please Note - Power-On reset must be performed
after changing the Dip Switch setting.
7. Link-Cross-Check
Link-Cross-Check allow user easily to identify and
diagnose the linking status. If set Link-Cross-Check switch
to Enable, UTP and Fiber port can link up only when both
linking conditions are good. In addition, if any of the fiber or
UTP port link down during operation, the other port will
also turn down link to alert the user and avoid packet loss.
Set Link-Cross-Check switch to Enable provide user
transparent link indication between two network devices
interconnected by GC-H21.
If Disable the Link-Cross-Check, the UTP and fiber port
will link up base on their individual linking condition.
Further, if fiber port link down during operation, it will not
turn down the UTP port link and vice versa.
8. Pure Converter Mode
This converter can also set to operate as a pure converter
without switching function by applying the following
settings:
Connecting to a 100Mbps Full Duplex:
Link-Cross-Check Enable (Pin 4 On)
TP Speed to 100Mbps (Pin 2 Off)
TP Duplex to Full (Pin 3 Off)
Connecting to a 100Mbps Half Duplex:
Link-Cross-Check Enable (Pin 4 On)
TP Speed to 100Mbps (Pin 2 Off)
TP Duplex to Half (Pin 3 On)
