Commissioning
Rudder order indicators connected to this output will require an adjustment
to ensure that the indicator reads the proper port and starboard hard over
angles as well as the zero degree midship position. The procedure for
making this adjustment through the DSC Setup Software is described in
section 4.1.2
or through the keypad setup in section 4.2.5.
2.4.5 Indicator Backlighting
Description
The indicator backlighting output provides the necessary signals to
illuminate the rudder angle and rudder order indicators. The indicator
lighting can be connected to a full power source or to a dimmed power
source that is controlled by the dimmer buttons connected to the steering
mode selection inputs. Multiple indicators lights are to be connected in
parallel to this output. The number of indicators connected will not affect
the level of illumination.
