See message fr=m James Lee the senior Honeywell tech-support, extremely sharp person., ver= helpful today! =94— Hi Larry,&nb=p; per our conversation,=my recommendation is to redo the Ethernet quadrax termination between Modma= and KANDU. This is very similar to other G550 that we have worked on last f=ll. The issue you're having with the heartbeat failure (MM failing t= receive heartbeat check) and 34% MM to KANDU packet drop resembles what we=saw. Those units also worked intermittently at times. =p class="MsoNormal" style="margin: 0in 0in 0.0001pt;"> I'm copying Jorge, Patrick, and Jonathan from=Gulfstream Savannah support engineering group as well as Scott in Westfield=(he will know which parts you need) who has worked on fixing the couple of q=adrax issues on two Honeywell G550s. My recommendation is to first revisit the installation drawing and cherk if quadrax is designed incorrectly. If so, update the drawing (Gulfstream=. Then, correct the quadrax ter=ination as required to fix the intermittent ping between MM and KANDU.=/o:p> =span style="background-color: rgba(255, 255, 255, 0);"> <= class="MsoNormal" style="margin: 0in 0in 0.0001pt;">Below is my note from last October w=rking on Honeywell G550.
