From: "dj_theis" Hi Art, I think it might be a case of belt and suspenders but in the industrial arena, it is not uncommon for vendors implementing CAN networks to recommend twisted + shielded cabling. https://www.belden.com/hubfs/resources/technical/technical-data/english/773105T.pdf?hsLang=en Granted, an airplane is not as electrically noisy as a modern manufacturing site but as I expect the more learned contibutors to the forum will advocate, following the vendors recommended installation practices is usually good advice. Best regards, Dan. -------- Scratch building Sonex #1362 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=491072#491072 ________________________________ Message 2 _____________________________________ Time: 03:29:31 PM PST US From: "Robert L.

Yeah . . . probably . . . but about the only way you can buy twisted pair is under a shield. I've probably got a few thousand feed of 2x22S . . . how many feet do you need . . . send me a mailing address Bob . . . ________________________________ Message 3 _____________________________________ Time: 03:40:04 PM PST US From: saolesen Subject: Re: AeroElectric-List: GNS 480 problems Thanks Dave and Charlie. I had a chance to go to the hangar briefly, so I checked the where the tray is placed. It is actually slightly proud on one side and even on the other. I noticed the panel screw was slightly loose so I tightened it , but that didnt fix the problem. Ill have more time tomorrow so Ill check out the pin depth placement. I had the back of the tray off to get a pin in for the position source for the ADS-B out transponder. That may have have moved the pins adversely. Thanks again!

Ive checked the wiring to the radio tray and there is the proper voltage at the proper pins. I also attached the 480 to a bench power supply and it turned on just fine. Sliding the radio back in the tray and turning it on there was nothing. So my question is: If I replace the female power and ground pins in the 37 pin dsub will that take care of the problem? I am thinking there is wear at the pin-socket junction. Is there something else I should look at? I have had no problems with the tray and the radio prior to this, so I am looking for some one who has solved the problem before.
