I purchased an Axiom 9 and Quantum radar to replace an older (dead) non-Raymarine Chartplotter/Radar. I wanted to network the new MFD with my existing Seatalk instruments. The Axiom 9 is connected to the ST1STNG device with a NMEA 2000 to STNG adapter cable and the ST4000+ Autopilot connected with a Seatalk adapter cable with the red wire cut and insulated. I discovered after days of testing that the power on sequence was critical. The Axiom and the ST4000+ have to be on prior to power being applied to the ST1STNG converter. I was unable to determine this from the manuals, this forum, the internet at large, or Raymarine Technical support. My goal is by posting this I will save someone else the days of testing I spent trying to learn this.
