Signal Descriptions
4.2.1 Host Port Signals
The host port is used to manage and monitor the CobraNet interface. Electrical operation
and protocol is detailed in the "Host Management Interface (HMI)" on page 23 of this
Manual.
The host port can operate in two modes in order to accomodate Motorola or Intel style
interfaces. The default mode is Motorola. Intel mode is set via a firmware modification.
4.2.2 Asynchronous Serial Port (UART Bridge) Signals
Level-shifting drive circuits are typically required between these signals and any external
connections.
