Evaluates: MAX22513 MAX22513 Evaluation Kit General Description Quick Start The MAX22513 evaluation kit (EV kit) consists of the Recommended Equipment evaluation board and software. The EV kit is a fully assembled MAX22513 EV kit (USB-A-to-micro-B cable included) and tested circuit board that evaluates the MAX22513 User-supplied Windows 10 PC with a spare USB port IO-Link device transceiver with integrated DC-DC buck regulators. 24V, 1A DC power supply The EV kit includes Windows -compatible software that Multimeter/voltmeter provides a graphical user interface (GUI) for exercising Note: In the following sections, software-related items are the features of the MAX22513. The EV kit is connected to identified by bolding. Text in bold refers to items directly a PC through a USB-A-to-micro-B cable. from the EV kit software. Text in bold and underlined refers to items from the Windows operating system. Features IO-Link-Compliant Device Transceiver Procedure The EV kit is fully assembled and tested.
