[TenTec] Ground Loop ?

[Bill_Ames@hyperion.com (Bill_Ames@hyperion.com)]

You should be able to implement your control interface using an optical
isolator. This eliminates the need for a common ground. Basically you have a led
that is turned on/off and a photo transistor that turns on/off. Not expensive.
