Evaluates: MAX14826 MAX14826 Evalution Kit General Description Quick Start The MAX14826 evaluation kit (EV kit) consists of the Recommended Equipment evaluation board and software. The EV kit is a fully assembled MAX14826 EV kit (USB A-to-B cable included) and tested circuit board that evaluates the MAX14826 User-supplied Windows XP, Windows Vista, or IO-Link device transceiver. Windows 7 PC with a spare USB port The EV kit includes Windows XP -, Windows Vista -, 24V, 100mA DC power supply and Windows 7-compatible software that provides a graphical user interface (GUI) for exercising the features Note: In the following sections, software-related items are of the device. The EV kit is connected to a PC through a identified by bolding. Text in bold refers to items directly USB A-to-B cable. from the EV kit software. Text in bold and underlined refers to items from the Windows operating system. Features Procedure IO-Link-Compliant Device Transceiver The EV kit is fully assembled and tested. Follow the steps IO and SPI Interface Terminals below to verify board operation before exercising the full Windows XP-, Windows Vista-, and Windows features of the device: 7-Compatible Software 1) Visit www.maximintegrated.com/evkitsoftware to USB-PC Connection (Cable Included) download the latest version of the EV kit software, 14826Rxx.ZIP. Save the EV kit software to a temporary Proven PCB Layout folder and uncompress the ZIP file. Fully Assembled and Tested 2) Install the EV kit software and USB driver on your computer by running the INSTALL.EXE program inside the temporary folder. The program files are copied to MAX14826 EV Kit Files your PC and icons are created in the Windows Start FILE DESCRIPTION Programs menu. During software installation, some versions of Windows may show a warning message Installs the EV kit files on INSTALL.EXE indicating that this software is from an unknown publisher. your computer This is not an error condition and it is safe to proceed with 14826.EXE Application program installation.

The second is through the Advanced User Interface 7) Verify that Hardware: Connected is displayed on the status bar at the bottom of the main window. window shown in Figure 2. The Advanced User Interface window becomes available by selecting the Options 8) Press the Read or Write buttons on the GUI to access Interface (Advanced User) menu item and allows execution the device SPI registers. of serial commands manually. Detailed Description of Software The Advanced User Interface window can also be used as a debug tool because it is capable of manually reading Operating in SPI Mode and writing to every register and logic pin of the device. To operate the device through the SPI interface, using the on-board microcontroller, set JU9 to 1-2 and ensure that Detailed Description of Hardware all shunts on JU10 are closed. JU11, JU12, JU13, and The MAX14826 EV kit provides a proven layout for the JU16 must be open in this mode. MAX14826 IO-Link device transceiver. Operating in Pin Mode All the power-supply and regulator input and output pins are connected to convenient connectors for easy To operate the device in pin mode, set JU9 to 2-3 and probing. The device logic input and output pins are also ensure that all shunts on JU10 are open. provided with convenient connectors for logic testing. The main window of the evaluation software (Figure 1) The transceivers C/Q, DO, and DI pins are protected by displays the SPI registers and the device pins that are Semtech SDC36 TVS diodes. connected to the on-board MAXQ2000 microcontroller. The user can send read or write SPI commands to the See Table 1 for a description of all the EV kit jumper device, configure the logic levels of the device input pins, configurations. and read back the logic levels of the device output pins. To read an SPI register or an output pin logic level, press the Read button. To configure an SPI register or an input pin logic level, first click on the desired radio button(s), and then press the Write button. The software also automatically monitors the presence of the wake-up pulse on the WU/THSD pin and displays the result on the GUI. The user can also change the SPI clock speed by clicking on the desired SPI Clock Speed radio button. Maxim Integrated 2 www.maximintegrated.com
