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).
Since most switches today typically
function as Masters, B&B Electronics
recommends configuring McBasic-
Gigabit as indicated in the table.

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.
