SW2 - Fiber Port 1 Full/Half-Duplex “FDX/HDX”
When the DIP-switch is in the Full Duplex “FDX” position (factory default), the fiber port will facilitate a
connection that supports Full-Duplex operation. Setting this DIP-switch to Half-Duplex “HDX” facilitates
a connection that supports only Half-Duplex.
3.2.1.3
SW3, SW4 - Reserved
These DIP-switches are for factory use only.
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 will facilitate a
connection that supports Full-Duplex operation. Setting this DIP-switch to Half-Duplex “HDX” facilitates
a connection that supports only Half-Duplex.
