Hi I'm working on a project with the waferstar gsm relay and I've run into a few problems with this hardware. First i tried programming through the sms commands and now when the relay is activated the actuator we are trying to throw will activate randomly afterwards infinitley until we disconnect power. I tried connecting to PC to check what lines are being read when the call is made and i don't have a 9 pin com port so I now have an adapter that goes from 9 pin to usb however when i plug the board into my PC it doesn't read as a device. i did take the sim out first not sure if that makes a difference but now when i put the sim in the relay activates constantly without a call or sms. anyone can help i would appreciate it.
