Additional Gigabit Features

Preferred/Forced Mode

In addition to Master/Slave Modes, McBasic-Gigabit module 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). This feature
is hardware configurable only.
Since most switches today typically

FX Negotiation on McBasic-Gigabit
McBasic-Gigabit module 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 McBasic-Gigabit module does not support Auto-Negotiation,
disabling the feature on the McBasic-Gigabit module forces the link up.
