1.3.5 Autopilot Acknowledge
1.4.4 Autopilot Request
Specifications
Command Voltage: ...................... 12 or 24VDC
Command Format:....................... Common positive or common negative
Galvanic Isolation: ....................... Yes (optical)
Cable Break Protection ................ No
Connector: ...................................5.08mm pitch screw terminals
Installation
These connections may be combined in the same cable as the autopilot
‘Request’ and ‘Acknowledge’ handshake signals (see 1.3.5 and 1.4.4).
Autopilot solenoid command signals may be positive common or negative
common and may be either 12 or 24 VDC.
Autopilots are interfaced to the steering control system using either these
solenoid command signals or the analog command signals (see 1.3.4
).
Commissioning
If the autopilot is interfaced using the solenoid command signals, the
Autopilot Type must be set to ‘On-Off’ through the DSC Setup Software’s
Autopilot Configuration window (see section 4.1.1
), or through the keypad
setup’s Autopilot menu screen (see section 4.2.4
). No other
commissioning procedures are required for this type of interface.
1.3.4 Autopilot Analog Command Signals
Description
The DSC can interface with autopilot systems outputting either directional
solenoid command signals or analog rudder order signals.
NOTE:
Whenever possible, the autopilot command interfacing should use analog
command signals. An autopilot which outputs analog rudder command
signals will normally not require its own rudder feedback signal.
The analog command input provides interfacing to autopilot systems
capable of outputting one or more differential analog command signals
