1.2 Extended systems

The ST5000 Plus is compatible with other Raymarine SeaTalk
instruments. Additional fixed and hand-held SeaTalk autopilot control
units can be connected at secondary steering and control positions.
A rudder reference unit can be fitted as an optional extra to the ST5000
Plus Sterndrive system, and will improve performance. It is especially
recommended if there is significant backlash in the steering system, or
optimum performance is required from a mechanical or cable steering
system.
