I've got intermittent problems with using ZillaView and ZillaConfig with my Zilla Z1K-LV. I've got the Hairball mounted in my rear trunk (Porsche 914). I've tried many different cable paths from the trunk to the passenger's seat and the only one that works is outside the trunk and along the exterior of the car. Any other path and these programs will lock up. I suspect EMI from either the motor or High Voltage wiring. An excellent email response from Otmar suggested a shielded cable but I tried that with no improvement. John (ZillaConfig inventor) said that he has experienced this emi and that a shielded twisted pair RS-232 cable helped and that it also seems to vary by which USB-RS232 dongle is used.

Anybody else experienced this problem or have an answer?

Thanks for any help!

You've tried using a shielded cable on the hairball, but that's really addressing the symptom rather than the cause. Have you tried shielding the potential source, i.e. the high voltage wire? They make zip-up casing to go around wires to provide EMI shielding. Just throwing out ideas, haven't dealt with the problem myself.

Thanks for the idea Phil. In my conversion there's just to many battery interconnects, HV wiring, controller, and motor between my Hairball and the passenger seat. To much stuff to shield it all. I can't avoid it my more than 6" or so if I run the cable inside. I guess by running it outside the car the car body is my "shield".

Is there any reason you can't just run it outside? You could just make a protective casing, like metal hosing (we use it in our data center) or PVC and just attach it to the underbody?
