NOTE: DIP-switches marked Reserved must be kept in the Left (factory default) position.
3.2.1.5 SW5 - Fiber Port 2 Full/Half Duplex “FDX/HDX”
When the DIP-switch is in the Full Duplex “FDX” position (factory default), the fiber port facilitates a
connection that supports Full-Duplex operation. Setting this DIP-switch to Half-Duplex “HDX” facilitates
a connection that supports only Half-Duplex.
3.2.1.6 SW6, SW7, SW8 - Link Modes
These three DIP-switches configure the link mode settings. The following table details possible Link Mode
DIP-switch configurations.

NOTE: Connecting two converters set to any of the RFD modes are illegal and will cause a “deadly
embrace” lockup.
NOTE: It is recommended to keep the LS setting (default) until initial configuration is complete.
