ES98 Comms to Quantum Radar

[morseg]

Good Morning
I recently installed new electronics on a 2003 Mainship trawler and have attached the wiring diagram. I am using an A78 MFD for a repeater and have not connected that, yet, but everything seems to be communicating but the Quantum scanner. The autopilot was existing. I have not actually tried to pilot a course yet, but it appears to be communicating as does the VHF and the ST60 Wind Indicator. I am hardwired with a Raynet cable and the scanner has WiFi capabilities but the MFD does not seem to sense the scanner in either mode. The radar acts like it is not powering up. I have checked power to the power cable, but not the end at the scanner. Before I take the scanner down to check power to that end of the cable, is there anything that I might be missing at the MFD that would give me those indications?
thanks
