Raymarine autopilot control unit - Manual (Page 82)

Chapter 5: Installation 65
SeaTalk Interface
If the ST7000 Plus has been linked to other instruments via SeaTalk,
the link can be checked as follows:
1. Press standby.
2. Select display illumination level 3 on any other SeaTalk
instrument or autopilot control unit.
The ST7000 Plus should immediately respond by switching on its
display illumination.
If the illumination does not switch on then a cabling fault exists in the
SeaTalk cabling between the ST7000 Plus control unit and the
instruments/control unit.
