TROUBLESHOOTING_USB.PDF USB driver installation help file Quick Start * One 12V DC power supply for VBAT 1) Visit www.maxim-ic.com/evkitsoftware to download the latest version of the EV kit software, 13036Rxx.ZIP. * MAX13036 EV system MAX13036 EV kit Maxim CMAXQUSB interface board (USB cable included) 2) Install the MAX13036 evaluation software on your computer by running the INSTALL.EXE program. The program files are copied and icons are created in the Windows Start menu. * A user-supplied Windows 98SE/2000/XP PC with a spare USB port 3) On the CMAXQUSB command module, ensure that the shunt of JU1 is in the 5V position. 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 98SE/2000/XP operating system. 4) For the MAX13036 EV kit, make sure the shunts of all jumpers are in the following default positions: Recommended Equipment Procedure The MAX13036 EV kit is fully assembled and tested. Follow the steps below to verify board operation. Caution: Do not turn on the power supply until all connections are completed. 2 JU1: (Open) JU2: (1-2) 5) Carefully connect the boards by aligning the MAX13036 EV kit's 40-pin connector with the 40-pin connector of the CMAXQUSB board. Gently press them together. The two boards should be flush against each other. _______________________________________________________________________________________ MAX13036 Evaluation Kit/Evaluation System 7) Switch S9 to Power On position. 8) Connect the USB cable from the PC to the CMAXQUSB board. If the CMAXQUSB board has not been previously installed, a Building Driver Database window pops up in addition to a New Hardware Found message. If you do not see a window that is similar to the one described above after 30 seconds, remove the USB cable from the CMAXQUSB and reconnect it. Administrator privileges are required to install the USB device driver on Windows 2000 and XP. Refer to the TROUBLESHOOTING_USB.PDF document included with the software if you have any problems during this step. 9) Follow the directions of the Add New Hardware Wizard to install the USB device driver. Choose the Search for the best driver for your device option. Specify the location of the device driver to be C:\Program Files\MAX13036 (default installation directory) using the Browse button. 10) Start the MAX13036 EV kit software by opening its icon in the Start menu. The GUI main window appears, as shown in Figure 1. 11) Change the position of switches S1-S8 on the EV kit board and observe the Switch Status change on the software GUI window. Figure 1.

Evaluate: MAX13036 MAX13036 Evaluation Kit/Evaluation System Detailed Description of Software Detailed Description of Hardware To start the MAX13036 EV kit software, double-click the MAX13036 EV kit icon that is created during installation. The GUI main window appears, as shown in Figure 1. There are five panels on the MAX13036 EV kit GUI software: IC Current Meter (0-199A), Switch Interrupt Enable, Key Scan Interval, Switch Configuration, and Switch Status. There are three buttons on the EV kit GUI software: Reconnect, Help, and Exit. However, the Reconnect button only appears in Demo Mode. The MAX13036 is an automotive contact monitor. The MAX13036 EV kit board provides a proven layout for evaluating the MAX13036. The EV kit comes with a MAX13036ATI+ installed. IC Current Meter Panel By pressing the Measure button on the IC Current Meter (0-199A) panel shown in Figure 1, the operating current of the MAX13036 will be displayed. The measuring range of this meter is from 0 to 199A. The Measure button will be grayed out (disabled) if the Apply Wetting Current checkbox on the Switch Configuration panel has been checked. Hysteresis Jumper (JU1) The MAX13036 hysteresis function is controlled by jumper JU1, as shown in Table 1. Refer to the IC data sheet for a detailed description. Table 1. Hysteresis Jumper Configuration (JU1) JUMPER SHUNT POSITION DESCRIPTION 1-2 Hysteresis set by resistor R2 Open* Hysteresis fixed at 0.16V x VBATREF JU1 *Default position. Switch Interrupt Enable Panel Power Supplies The Switch Interrupt Enable panel contains eight checkboxes (S1-S8) that individually control the interrupt enable bit of each switch. The MAX13036 EV kit can be powered from two 9V batteries connected to battery connectors BAT1 and BAT2, or from a user-supplied 7V to 27V power supply connected to VBAT. There is an optional power-on indicator LED (D3) on the EV kit board. Jumper JU2, as shown in Table 2, determines whether this indicator is enabled or disabled Key Scan Interval Panel The pulldown menu on the Key Scan Interval panel is used to program the scanning-time period. Please refer to the MAX13036 IC data sheet for a detailed description. Switch Configuration Panel The Switch Configuration panel contains the Shutdown Mode checkbox, Apply Wetting Current, Pulsed, and Enable Direct Input checkboxes. It also contains radio buttons that control the polarity of S8, S7 and S6, S5. The Interrupt Flag shows the current status of the MAX13036 INT pin. The Shutdown Mode checkbox controls the MAX13036 SD pin. Apply Wetting Current, Pulsed, and Enable Direct Input checkboxes individually control the internal corresponding control bit. Table 2. Power-On Indicator D3 Configuration (JU2) JUMPER JU2 SHUNT POSITION DESCRIPTION 1-2* D3 enabled Open D3 disabled *Default position. Toggle Switches S1-S4 are two-position switches. S5-S8 are three-position switches, with the OFF position in the center. Reconnect, Help, and Exit Buttons Press the Reconnect button to reestablish the connection between the EV kit GUI software and MAX13036 EV kit hardware. Note: This button only appears in Demo Mode. Press the Help button to show the MAX13036 EV kit software version and Maxim's website information. Press the Exit button to quit the MAX13036 EV kit GUI software. 4 _______________________________________________________________________________________ R1 1k 1% CLBT1 JU1 +5V R3 200k R2 91k 2 1 OT INT SD1 MISO MOSI SCLK U6-A D1 VBAT TDEB IWET HYST OT INT SD SDO SDI CLK 2 N1 3 24 3 2 1 C1 0.01F R7 100k 12 21 22 7 6 5 4 3 2 1 28 R5 1k 1% +5V MAX5084 U5 C8 0.1F R4 953 1% GND EN IN DO1 DO0 IN7 IN6 IN5 IN4 IN3 IN1 IN0 IN2 VL 19 U1 BAT 26 1 +5V MAX13036 BATREF CS 1 C10 0.1F 7 C7 1000pF 11 10 9 13 14 23 18 17 16 15 25 2 GND CS1 JU3 GND VBAT C17 47F 2 3 1 C11 1F SET OS OUT IN- IN+ 2 2 2 2 U2 +5V +5V S4 S3 S2 S1 C19 OPEN R6 24k 1% 1 1 1 1 GND OUT VCC C2 0.01F C15 1F MAX4238 SHDN 4 5 6 DO1 DO0 IN7 IN6 IN5 IN4 IN3 IN2 IN1 IN0 4 6 7 +5V 2 2 3 1 3 1 3 2 1 C12 1F VBAT S7 S5 U3 INT 2 2 OUT 6 S8 C3 0.01F +5V VBAT VBAT VBAT S6 IN1 IN0 TEMP GND 4 MAX6143 5 SHDN TRIM IN IN1 IN0 R8 1M 1% 3 1 3 1 +5V C13 1F 4 U6-B C16 2.2F 6 5 +5V VBAT VBAT +5V C6 0.01F 3 C20 0.1F +5V C4 0.01F +5V SD1 9 10 3 1 2 AGND2 AIN U4 +5V DGND DOUT SCLK CS DVDD C5 0.01F MAX1162 AGND1 REF AVDD C14 1F R9 1M 1% MISO SCLK J1-1 J1-3 J1-5 J1-7 J1-9 J1-11 J1-13 J1-15 J1-17 J1-19 J1-21 J1-23 J1-25 J1-27 J1-29 J1-31 J1-33 J1-35 J1-37 J1-39 7 6 5 4 8 +5V J1-2 J1-4 J1-6 J1-8 J1-10 J1-12 J1-14 J1-16 J1-18 J1-20 J1-22 J1-24 J1-26 J1-28 J1-30 J1-32 J1-34 J1-36 J1-38 J1-40 J1 MISO SCLK CS2 IN3 IN2 IN1 IN0 CLBT1 OT CS2 MOSI CS1 C18 47F C24 OPEN C23 OPEN C22 OPEN C21 OPEN VBAT VBAT + BAT1 - F1 J2-5 J2-4 J2-3 J2-2 J2-1 J2 JU2 - + BAT2 2 IN7 IN6 IN5 IN4 R10 2k S9 D3 2 C28 OPEN C27 OPEN C26 OPEN C25 OPEN 1 VBAT F2 1 2 D2 1 J3 J3-6 J3-5 J3-4 J3-3 J3-2 J3-1 GND VBAT Evaluate: MAX13036 C9 0.1F MAX13036 Evaluation Kit/Evaluation System Figure 2.
