===== USB Connector ===== | ===== USB Connector ===== | ||
+ | The Micro USB connector, P6, on the EVAL-AD5940BIOZ board serves 2 functions. | ||
+ | * The provided ECG cables can be connected to a human body simulator which can be used to verify ECG, body composition etc. Note: The EVAL-AD5940BIOZ must never be connected to the human body while the board is connected to a PC or Laptop | ||
+ | * The provided AD5940 Z Test board can also be connected to the Micro USB connecter. This board contains a number of banks of resistors and capacitors which can be used to model Body Impedance, Skin Impedance, Electrode impedances and Contact impedance. These resistor values are configured with the various switches. | ||
+ | Note, P6 USB connector must only be used with the supplied AD5940 Z Test board or the provided ECG Cables. No other cable should ever be connected. | ||
