Configurator tool. After programming and executing a firmware image from an external SPI Flash, the firmware revision can be quickly identified by enumerating the EVB-USB4x12 to a USB host PC and inspecting the USB Device ID (bcdDevice) of the USB2.0 hub. See Figure 3-1. -
Page 18: Power Source
EVB-USB4x12 Evaluation Board User’s Guide 3.1.2 Power Source The EVB-USB4x12 must be powered externally through the J1 4-Pin DIN connector, or through the J5 terminal block. The supported input voltage range for the base board is 12V to 24V. By default, the sup- plied PM-PD requires an input of 24V to properly regulate up to 20V volts to the upstream PD ports. -
