Note Required Equipment on the EV kit, the on-board 3.3V USB LED supply MAX2253x EV kit (green LED) is on, indicating the hardware is powered Micro-USB cable up. Windows 10, Windows 8.1, and Windows 7 with a 5. Once the hardware is ready to use, launch the EV kit spare USB port software by opening its icon from either the Desktop or Multimeter Start Programs menu. The EV kit software appears DC voltage supply (up to 120V, 0.01A, or higher) as shown in the Figure 1. 6. If the software is launched with the EV kit connected, Note: In the following sections, software-related items are the hardware is detected, and the lower-right status bar identified by bolding. Text in bold refers to items directly indicates Connected. If the hardware is connected from the EV kit software. Text in bold and underlined after the software is launched, from the Device menu, refers to items from the Windows operating system. click Search for Hardware as shown in the Figure 2. Procedure Then select a device in the list or use the default device already selected. The EV kit is fully assembled and tested. Follow the steps 7. Connect the positive terminal of the DC supply to pin 1 to install the EV kit software, make required hardware (IN1) of terminal J2 on the EV kit. Connect the negative connections, and start operation of the kit. The EV kit terminal of the DC supply to pin 5 (AGND) of terminal software can be run without hardware attached. Note that J2 on the EV kit. after communication is established, the IC must still be 8. Configure the DC supply output to be 100V and enable configured correctly for desired operation mode. Make the supply output. sure the PC is connected to the internet throughout the 9.
