Duplex Mode setting
The TP port of FT-80X supports duplex mode detection by auto-
negotiation (A-N). The following is the duplex mode parameters:
Fast Ethernet Device FT-80X Duplex Mode
support
Ethernet / Fast Ethernet Hub Half-Duplex
Ethernet / Fast Ethernet Switch
(without A-N) Half-Duplex
Fast Ethernet Devices *
Support Auto-Negotiation Full-Duplex / Half-
Duplex

NOTE:
Normally, an A-N switch will detect and set to
full-duplex, where a dual-speed hub will detects
half.
There is a DIP-switch as in the left view as section 4. Please check
and follow the duplex mode of the fiber device and have the
duplex selection to your FT-80X.
