Volvo Penta IPS Autopilot System
NMEA 2000
Using one of the SHORT SeaTalk
2
cables, connect the NMEA 2000 terminal on the
DPU to the FOURTH terminal of the 5way SeaTalk
2
connector block.
Securing cables and replacing cover
When all of the DPU cables have all been connected, secure each cable to the
loops on the DPU, using the cable ties provided.
When all cables are secure, replace the DPU cover.
Do not use the DPU with the cover removed, as this could degrade the EMC
performance.
1.11 Additional connections
Three more connections now need to be made to the 5way connector block.
SeaTalk
2
terminator
Plug the SeaTalk
2
terminator into the CENTER terminal on the 5way SeaTalk
2
connector block.
Grounding the system
In order to meet the system EMC specification, the SeaTalk
2
cable screen must be
connected to the vessel’s RF ground point.
Using the grounding cable
Raymarine provide a madeup, RF grounding cable that you are recommended to
use, to ground the system.
The grounding cable is yellow and has a SeaTalk
2
connector at one end. Connect
this to the FIRST terminal of the 5way SeaTalk
2
connector block. The
