78M6610+PSU Evaluation Kit User Manual 1.4 Safety and ESD Notes EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT! Standard ESD precautions must be taken when handling electronic equipment. The 78M6610+PSU contains ESD protected interfaces. Do not connect test equipment or external development boards directly to the 78M6610+PSU hardware. Damage to the 78M6610+PSU and external equipment will occur due to the 78M6610+PSU’s “high side” reference topology. The 78M6610+PSU’s V3P3 supply rail (i.e.
8M6610+PSU Evaluation Kit User Manual 2 Installation 2.1 USB Driver Installation This Evaluation Kit includes an isolated USB interface for serial communications with a PC. The FTDI USB controller IC FT232R performs the USB functions. The FTDI Windows driver presents a virtual COM port for enabling serial communications. The FTDI Windows driver is a certified driver for Windows XP and Windows 7.
78M6610+PSU Evaluation Kit User Manual • The System Properties screen appears. Click on the Hardware tab. Click on Device Manager. Under Ports (COM & LPT), look for the USB Serial Port assignment. • Take note of the COM port assignment for the USB Serial Port. COM Port: 2.2.1 FTDI COM Port Trouble Shooting If the FTDI device driver did not install properly, there would be no assigned COM port number for the FTDI controller. Repeat the USB Driver Installation, see Section 2.1.
78M6610+PSU Evaluation Kit User Manual 2.3 Basic Connection Setup Figure 1 shows the basic connections of the 78M6610+PSU Evaluation Kit for use with external equipment. The shunt adaptor board consists of the host side components necessary for the evaluation environment that would be replaced by the target system. This host board provides a USB serial UART controller, serial interface DC-DC power isolator, a current shunt, and AC wiring terminals.
78M6610+PSU Evaluation Kit User Manual Attach an AC source and AC load to the Shunt Adaptor Board as shown below. Connect J1 and J3 to an external AC power source. Connect J2 and J4 to the load to be measured. The 78M6610+PSU Evaluation Kit hardware is designed for 120 VAC and 230 VAC (nominal) up to 300 VAC (max).
