JP1 Setting
Store-and-forward
Smart-forward
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:
1. In direct conversion, be sure both devices connected to the TP port and FX port have same duplex
mode for proper transmission.
2. 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.
3. In direct conversion, the media converter is not limited to the maximal length of the receiving
packets.
