3.1.1 Forwarding Mode Setting JP1

The following table lists the forward method used in different TP to FX conversions:

JP1 Setting

TP port to/from FX port

Forward method

Store-and-forward

10BASE-T to 100BASE-FX

Store and forward

100BASE-TX to 100BASE-FX

Store and forward

Smart-forward

10BASE-T to 100BASE-FX

Store and forward

100BASE-TX to 100BASE-FX

Direct conversion

On smart-forward mode, the converter can change to direct conversion automatically when it detects

same speed on both TP port and FX port. Direct conversion method converts the signal between TP

port and FX port without storing the received packet on one port then forwarding to another port. The

media converter operates with the minimum latency.

Note:

In direct conversion, be sure both devices connected to the TP port and FX port have same duplex

mode for proper transmission.

In direct conversion, 802.3x function is disabled and the media converter will not generate pause

frame, but just forwards the received pause frame directly from one port to another port.

In direct conversion, the media converter is not limited to the maximal length of the receiving

packets.
