I just installed the XeThru Explorer software on windows 7. The text looks a bit weird (fuzzy), but anyway -- it just says: "Please connect your XeThru sensor device". I have connected the sensor and it's being detected by Windows as USB to UART device. Am I missing something essential? The sensors came preloaded with firmware right? It might be my windows also, I'm having lots of trouble with it. Going to switch to Linux now and see if I can get some communication going directly with the serial port. Update: I can communicate with the sensor directly through the serial port, so must be a SW problem..
