Raytheon ST6000 Plus - Seatalk Interface

Chapter 6: Installation

SeaTalk interface
If the ST6000 Plus has been linked to other SeaTalk 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 ST6000 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 ST6000 Plus control head and the
instruments/control unit.
