Quick StartRecommended Equipment• MAX14819 EV kit (USB A-to-B cable included)• User-supplied Windows 7 PC with a spare USB port• 24V, 1A DC power supply*• Multimeter/voltmeter*L+A and L+B are each configured for a 1A (typ) current limit, so a higher load-capable power supply may be required for testing.Note: In the following sections, software-related items are identified by bolding. Text in bold refers to items directly from the EV kit software. Text in bold and underlined refers to items from the Windows operating system.
ProcedureThe EV kit is fully assembled and tested. Follow the steps below to verify board operation before exercising the full features of the device:1) Visit www.maximintegrated.com/evkitsoftware to
download the latest version of the EV kit software, MAX14819EVKITSetupVx.xx.ZIP. Save the EV kit software to a temporary folder and uncompress the ZIP file.
2) Install the EV kit software and USB driver on your computer by running the MAX14819EVKITSetupVx.xx.EXE program inside the temporary folder. The program files are copied to your PC and icons are created in the Windows Start | Programs | Maxim Integrated menu. During software installation, some versions of Windows may show a warning message indicating that this software is from an unknown publisher. This is not an error condition and it is safe to proceed with installation. Administrator privileges are required to install the USB device driver on Windows.
3) Verify that all the jumpers are in their default positions, as shown in Table 1.
4) Connect the 24V DC power supply on the VCC and GND connectors on the EV kit board.
5) Connect the multimeter to the V5 testpoint (TP22)6) Connect the USB cable from the PC to the EV kit
board. A Windows message appears when connecting the EV kit board to the PC for the first time. Each version of Windows has a slightly different message. If you see a Windows message stating ready to use, then proceed to the next step.
7) Start the EV kit software by opening its icon in the Windows Start | Programs | Maxim Integrated menu. The EV kit software main window appears, as shown in Figure 1.
8) Verify that Status: MAX14819EVKIT A Connected is displayed on the status bar at the bottom of the main window (Figure 1).
9) Turn on the 24V supply. Ensure that the V5 voltage (TP22) is 5V.
10) Click on the Read All button to read all of the registers in the device.
11) Select a register in the register table to access the bits in that register by clicking on the register name.
12) Using the Register Bit Description table that pops up, set the individual bits by selecting the required setting from the drop-down menu for each bit.
13) Press the Write Changes button on the GUI to write the registers that have been changed to the MAX14819.
Detailed Description of SoftwareConfiguring the RegistersClick on a register name in the register table to access the individual bits in that register. When the register name is selected in the register table, a corresponding Register Bit Description table appears, allowing access to set individual bits. Click on the drop-down menu next to each bit in the Register Bit Description table to select the bit
setting. When all of the bits are set as desired, click on the Write Changes button to write the changed bit setting s to the MAX14819 over the SPI interface.Note that full IO-Link communication is not available using the EV kit GUI. Please use the MAXREFDES145 for full IO-Link communication with the MAX14819.
Interrupt Response (IRQ)The MAX14819 features an integrated active-low interrupt indicator pin to actively notify the controller when an interrupt or error condition occurs. Enable interrupts in the by setting the bits in the InterruptEn register.When an interrupt is triggered, the IRQ bit in the SPI communication is set and the IRQ in the SPI Response box of the GUI turns red. On the EV kit PCB, the IRQ LED (DS6) also turns on.
Detailed Description of HardwareThe MAX14819 EV kit includes the MAX14819 dual-channel IO-Link master transceiver and the external components for evaluating the device. All logic-level I/Os and IO-Link capable I/Os are available on yellow test points.Logic-Level Power Supply The MAX14819 features an internal 5V linear regulator which can drive loads up to 20mA. When REGEN is unconnected, this 5V output is available on the V5 test point (TP22). Leave J13 open and close the J5 jumper to use this internal 5V regulator to power the logic level supply (VL).To use a different logic-level voltage supply, open the J5 jumper and apply the external supply to the VL testpoint (TP23). Selecting the Device AddressThe MAX14819 includes two address pins for SPI addressing, allowing up to four devices on a single bus. Set the SPI address for the MAX14819 on the MAX14819EVKIT by setting the A1 and A0 jumpers (J11 and J12, respectively). Set the device SPI address in the GUI to the same value by selecting the corresponding address in the drop-down menu in the SPI Address box.
Using SPI Interface with an External Master Controller The MAX14819 EV kit includes an isolated USB-to-SPI interface circuit for communication with the PC/GUI.To use an external SPI master controller with the MAX14819, open all of the channels on SW1, and con-nect an the external SPI master to the J20 header. Note that the J20 header is not isolated from the MAX14819.
