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).

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.
