2.4 OUTPUTS
2.4.1 Steering Mode Indication
Description
The steering mode indicator output provides dimmable signals for
illumination of steering mode indicators. The output provides a common
12V or 24V supply for driving the positive side of the indicators and a
pulse width modulated signal sinking to ground for turning on each
indicator. The pulse width modulated signal provides control over the
level of illumination using the up and down dimmer input buttons. Eight
configurable steering mode outputs are available as well as dedicated
outputs for FAULT, LOCK OUT and general backlighting indicators. One
dedicated non-dimming output is provided for activation of an audio
device. Steering modes are assigned to the configurable outputs through
the DSC while unused outputs are turned off. Any of the configurable
outputs can be assigned functions for either steering mode, rudder speed
control or station transfer.
