Omnitron Systems Technology 2FXM2 user manual 1.5 SW5 Fiber Port 2 Full/Half Duplex FDX/HDX

NOTE: DIP-switches marked Reserved must be kept in the Left (factory default) position.

3.2.1.5SW5 - 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.

3.2.1.6SW6, SW7, SW8 - Link Modes

These three DIP-switches configure the link mode settings. The following table details possible Link Mode DIP-switch configurations.

SW6	SW7	SW8	Result
Left	Left	Left	Link Segment mode (LS)
Right	Left	Left	Link Propagate mode (LP)
Left	Right	Left	Remote Fault Detection mode plus Link
			Segment mode (RFD+LS)
Right	Right	Left	Remote Fault Detection mode plus Link
			Propagation mode (RFD+LP)
Left	Left	Right	Symmetrical Fault Detect mode (SFD)
Right	Left	Right	Asymmetrical LP P1 to P2 (ALP P1-P2)
Left	Right	Right	Asymmetrical LP P2 to P1 (ALP P2-P1)
Right	Right	Right	Asymmetrical RFD+LP P1 to P2

SW6	SW7	SW8	Result
Down	Down	Down	Link Segment mode (LS)
Up	Down	Down	Link Propagate mode (LP)
Down	Up	Down	Remote Fault Detection mode plus Link
			Segment mode (RFD+LS)
Up	Up	Down	Remote Fault Detection mode plus Link
			Propagation mode (RFD+LP)
Down	Down	Up	Symmetrical Fault Detect mode (SFD)
Up	Down	Up	Asymmetrical LP P1 to P2 (ALP P1-P2)
Down	Up	Up	Asymmetrical LP P2 to P1 (ALP P2-P1)
Up	Up	Up	Asymmetrical RFD+LP P1 to P2

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.
