5.9 EXPANSION PROCESSOR
5.9.1 The Expansion Processor
The Expansion Unit can be connected to the Hydra 2000 System
via the Fastnet to drive four extra analogues (meters 5,6,7 and 8),
and provide extra linear inputs.
A new menu automatically appears on all FFD’s called EXPAND
when an Expansion Processor is added to the system. Up to
twelve linear functions may be displayed numbered LINEAR 5 to
LINEAR 16. Initially only LINEAR 5 is shown. A linear function by
default shows a number between 0, representing 0 volts on its
input and 1000 representing 6.5 volts on its input. The voltage
change is assumed to be linear in relationship. Hence an external
sensor, for example a load cell giving a linear change in voltage as
the load increases, may be connected to a linear input.
LINEAR 5 has four calibration values, other linear functions have
three calibration values found by selecting CALBRATE on the
appropriate linear function.
5.9.2 Linear Function Settings
Altering calibration value 1 (CAL VAL 1) allows the correct input
sensor to be selected. The different inputs available are shown
below:
1 or 2 normal linear input 0 to 1000
3 rotating mast correction for apparent wind angle
4 heel angle
5 trim angle
6 barometric pressure
7 rudder angle
8 air temperature
The default factory setting for a linear input is 1 (0-1000 format).
Note
Do not set different linear inputs to the same function (except 1 for
normal linear input) or the calibration value will be ignored. This
ensures that no function uses no more than one analogue input.
However, any one of the Linear 1 to 4 inputs from the main
