3.1 GUI Installation and Communication Setup

A Graphical User Interface (GUI) is available for download on the product page which allows access to individual registers as well as PMBus communication. The GUI requires an MCP2221A Breakout Module available separately (https://www.microchip.com/en-us/development-tool/ADM00559 or https://www.microchip.com/en-us/development-tool/BB62Z76A), connected to the reference design telemetry header J4, to communicate with the two MCPF1525M06 modules. This connection is shown in Figure 2-1.
