3.1 Quick Start Setup

The following instructions describe how to set up and use the EVM.

  1. Purchase a SCB if you do not already have one.
  2. Download this driver and install it as an administrator: https://www.ti.com/lit/zip/sbac253.
    1. Follow the download prompts. An account on my.TI™ on-line information services is required.
    2. Take note that this driver is labeled as a PAMB driver and is also used for the SCB.
  3. Attach the EVM to the SCB Controller as shown in Figure 3-1.
    1. Refer to Figure 3-2 when connecting multiple EVMs of the same type together.
  4. Connect the EVM to the PC using a USB cable.
    1. Insert the micro-USB cable into the SCB Controller onboard USB receptacle J2.
    2. Plug the other end of the USB cable into a PC.
  5. Access the GUI from this link in either Chrome, Firefox, or Safari: https://dev.ti.com/gallery/info/CurrentSensing/INA700EVM_GUI/.
  6. Connect the GND reference of the external system to the GND node of the EVM (pin 1 of J1).
  7. Ensure the load current is disabled, then place the INA700 IN+ and IN– nodes to the load line by connecting the signal leads to J1 pin 5 or 6 and J1 pin 3 or 4 on the EVM as explained in Current Sensing Operation.
