I'm testing with the ADS1232REF EVM right now, and the "Mode" switch seems to have no effect on the system. I have it connected to a 9V battery, internal 5V Vref, and have the 5V, GND, IN+, and IN- jumpers connected. When I turn on the device in scale mode, it boots up and says "No Data" then goes straight into raw Hex output on the display. When I turn it on in Analysis mode, it does the same startup but then does not register the "Mode" switch in any way when I toggle it. Could this be a hardware issue with the "Mode" switch, or am I likely just configuring it incorrectly?
