Commissioning

If the autopilot is interfaced using the analog command signals, the

Autopilot Type must be set to ‘Analog’ 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

). Other adjustment

parameters for the analog command signals are also described in these

sections.

1.3.5 Autopilot Acknowledge

Description

The Autopilot Acknowledge signal is one half of the DSC / Autopilot

handshake which is designed to ensure that control will not be transferred

unless both systems agree. The other half of the handshake is the

Autopilot Request signal described in section 1.4.4

The DSC will not

move the rudder in response to autopilot rudder commands until both the

request and acknowledge conditions have been met.

The Autopilot Acknowledge input reads the status of a dry contact which is

part of the autopilot system. When the autopilot system is ready to output

steering commands and assume control of the rudder it is to close the dry

contact connected to this input. Autopilot systems normally refer to this

signal as ‘auto on’ or ‘drive engage’.

NOTE:

Refer to specific autopilot system for information pertaining to the

availability and functionality of this interface signal.
