[CA] AIS 250 Install

[Chuck - Raymarine - Moderator]

Chris,

Per our conversation, the diagram shown below is very close to being correct with respect to how the autopilot and engine would be interfaced to a C-Series Classic MFD. The following changes should be made:
1) The "Battery" feed should be changed to specify switched 12VDC
2) The referenced to "ECM" should be changed to ACU100 (please verify ... if found to be a ACU200, then its SeaTalkng/NMEA 2000 power switch should be moved to the OFF position)
3) Show the connections to the ACU and EV-1 as spurs to T-Pieces within the blue backbone
4) Show termination plug installed within the last T-Piece within the backbone cable
5) Show the D244 Junction Block
- Supplied SeaTalkng Converter to SeaTalk Cable connected to D244
- SeaTalk cable spliced to Raystar 125 GPS Sensor's (model assumed) cable and then plugged into D244
- SeaTalk Cable plugged into D244 and then into MFD's SeaTalk socket. This cable must be cut and then all leads except for its red lead spliced back together. Insulate the red leads to prevent shorting.
6) Add switched 12VDC to the 5-Way connector
