Intelligent Tilt/Swivel with Protocol Conversion

      Disclosed is a means of using a monitor tilt/swivel base to
house a protocol converter.  This converter allows the connection of
several PC peripherals to the ACCESS.bus which is used as a
communication link between the PC and attached monitor.

      In a typical PC configuration a user has a monitor, keyboard,
pointing device and printer.  Each has it's own connection to the PC
system unit.  A communication channel between the system unit and
monitor was identified for the purpose of reading monitor information
such that the system may optimally configure it's graphics system.
The defined communication channel is known as the Display Data
Channel or simply as DDC.

      In a mode of operation of this channel, the ACCESS.bus protocol
is supported.  This allows serial data transfer among the attached
devices.  An obvious application of this channel is then to use it as
a means of providing an alternative connection between the user's
peripherals and the PC system.

      The pointing device, printer and keyboard each have a unique
communication protocol for operation.  This invention proposes that a
protocol converter be used to convert from that of each of the
peripherals to the ACCESS.bus.  In this way it is then possible for
the DDC link to carry this information between the peripherals and
the system unit.

      In order that standard parts may be used wherever possible, a
preferred solu...
