Host Strobe
The host port is used to manage and monitor the CobraNet interface. Electrical operation
and protocol is detailed in the
Manual.
The host port can operate in two modes in order to accomodate Motorola
interfaces. The default mode is Motorola. Intel mode is set via a firmware modification.
Level-shifting drive circuits are typically required between these signals and any external
connections.
