ADS1248EVM-PDK

Other Parts Discussed in Thread: ADCPRO

I am trying to get my 1248 eval kit to function.  I have loaded ADCpro adn updated the firmware but it does not appear to be seeing the RTD's when I hook them up.  My internal reference is ON power supply set to 5Volts IDAC is off, no connection on VBIAS.  I am using a 100 ohm RTD hooked up to AIN0 and AIN1 with the third lead floating.  What am I missing?  I have the data monitor running and the data I am getting makes no sense.

 

Thank you,

Mike
