C Bus
Intended for use with code-plugs used to identify drivers, calibrate, diagnose faults,
upload firmware and new configurations, and to download logged data and unit specific
configuration information. This bus can also be used to drive the FM Keypad which can
be used for selecting driving reasons and allows the driver to make voice calls when
used with the FM Voice Kit.
TTL Level Serial Port
Intended to be used by devices designed to work on a bus. The bus was specified to be
a Multi-Master type to enable other intelligent devices to optionally work as master,
relieving the FM 3617i/FM 3717i/ FM 3817i of processing.
