-The USB connector provides an interface to connected the USB to Crocodile cable to the AD5940. This USB connector must NEVER be connected to power. If this happens the the AD5940 may become permanently destroyed.+The USB connector provides an interface to connected the provided USB to Crocodile cable to the AD5940. This USB connector is only intended to be used in conjunction with the provided USB to crocodile cable. No other USB cable should be ever be connected.

 +The following table shows which color lead corresponds to which input: 
 +^ Cable Color ^Description ^ Schematic Reference ^ 
 +| Red         | Counter Electrode | USB_1    |  
 +| Blue/white | Reference Electrode | USB_2 |  
 +| Green | Working Electrode | USB_3| 
 +| Black         | Connected to DE0 input | USB_4|

 +The image below shows the crocodile connected to the EVAL-AD5940ELCZ. A dummy sensor consisting of a Resistor in parallel with a capacitor is connected. The counter and reference connectors are connected to one end and the working electrode is connected to the other end.

 +Note, the USB to crocodile cable is intended for rapid prototyping. There is a parasitic resistance and capacitance associated with it which may effect measurement accuracy. This is especially through for high frequency impedance measurements.

 ===== BNC Connector ===== ===== BNC Connector =====
 The BNC connector is connected to the AD5940 via LTC6078 amplifier. This amplifier can be used with high impedance sensor's such as pH sensors and for water conductivity measurements. The BNC connector is connected to the AD5940 via LTC6078 amplifier.
