4.5 Getting Started With the SNSR-DUAL-ADC-EVM

The following list of steps provides an overview to quickly get the SNSR-DUAL-ADC-EVM setup and operational. The subsequent sections in this document expand on each step and explain in detail the SNSR-DUAL-ADC-EVM available features. Links are provided to navigate from this quick-start guide to the appropriate section at each step, where applicable:

  1. Remove the SNSR-DUAL-ADC-EVM and USB cable from the box.
  2. Connect the A-to-Micro-B USB cable from EVM directly to a USB port on the computer. Do not connect the cable through a USB hub. A green LED on the EVM indicates a valid connection.
  3. Power the EVM using one of the power connection options in Table 5-1.
  4. Connect sensors or signals to the input terminal block J6 and the excitation terminal block J4.
    1. Measuring a Voltage-Excited 6-wire Bridge Using ADC1 and a Low-side Bias Resistor Using ADC2
    2. Measuring a Voltage-Excited 6-wire Bridge Using ADC1 and a Current-Excited 2-wire RTD Using ADC2
    3. Measuring a Current-Excited 4-wire Bridge Using ADC1 and a Voltage-Excited Thermistor Using ADC2
    4. Measuring a Thermocouple Using ADC1 and an NTC for Cold-Junction-Compensation Using ADC2
    5. Measuring One 3-wire RTD Using ADC1 and One 3-wire RTD Using ADC2
    6. Measuring One 4-wire RTD Using ADC1 and One 4-wire RTD Using ADC2
    7. Measuring Generic Voltage or Current Inputs
  5. Open a terminal program.
    1. Use the integrated serial terminal in Code Composer Studio if a terminal program is not installed.
  6. The EVM arrives with firmware programmed and is therefore ready to use out of the box. Data can be captured and streamed from the system without any additional components or boards.
    1. The Software section describes these programmed functions.
