Additional Gigabit Compact Media Converter Features
Preferred/Forced Mode
In addition to Master/Slave Modes, Gigabit converter also includes Preferred/Forced
Modes for Master/Slave negotiation. Preferred Mode helps determine whether the
module should act as a Master or Slave. Forced Mode should typically only be used when
connecting to some legacy switches, or when there is difficulty establishing a link. The
default is Preferred Mode (S1-1 is ON).

FX Negotiation on Gigabit Compact Media Converter
Gigabit converter includes the FX Auto Negotiation feature which negotiates duplex
mode. This feature must be enabled or disabled on both ends of the connection or there
may have difficulty establishing a link. If the device being connected to the Gigabit
converter does not support Auto Negotiation, disabling the feature on the Gigabit
converter forces the link up.
