NCV7430GEVK Advance Information USB-LIN Interface V3 Evaluation Board User'sManual http://onsemi.com Introduction USB−LIN Interface provides a simple USB interface that connects PC and LIN based slave device. The USB part is self−powered and optically isolated from the LIN transceiver that can be supplied either via dedicated DC input connector or directly via LIN connector. This device is compatible e.g. with NCV7430 Evaluation software which incorporates all the necessary drivers. The design incorporates the lowest bill of materials, minimized board size and allows easy interconnection in case of multiple nodes network.

Connect LIN Interface to USB and wait until the device is installed. This step requires administrator rights. 3. Connect the boards according to figure below. Initially all the nodes have address set to default value 0. In case the node addresses haven’t been set previously, connect only one node to USB−LIN interface to avoid having two nodes with same address connected to the network. This section contains instructions for the NCV7430 setup configuration and first connection. Only a few steps need be proceeded to get fully working simple LIN RGB LED network. Please take the following steps to get a functional setup: 1. Install the NCV7430 Evaluation Software (see the NCV7430 Evaluation Software section for details). The USB drivers are included in the installation package. This installation requires administrator rights. LIN Interface Version 3 12V DC USB USB Power LIN Activity LIN Power LIN Figure 4. Example of LIN Interface Connection − NCV7430 Evaluation Setup 4. Run the NCV7430 Evaluation Software. 5. Select one of the nodes from “Nodes” table (detected nodes are highlighted in yellow), http://onsemi.com 3 NCV7430GEVK Figure 5. NCV7430 Evaluation Software Preview 6. To switch the LED to On state set the parameters in Set Color group box according to picture below and select Transmit. The color setting can be freely modified. Then set the parameters in Set LED Control group box and select Transmit. These two commands can be sent in any order. 7. LED should be turned on with preset color. NCV7430 EVALUATION SOFTWARE Installation Procedure ON Semiconductor LIN Interface works in combination with the custom NCV7430 Evaluation Software. 1. Please check if Microsoft .NET Framework 4.0 is installed on your computer. If not, run dotNetFx40_Full_setup.exe prior to the NCV7430 Evaluation software installation. 2. Run NCV7430 Evaluation Setup.exe and follow the installation wizard instructions. Minimum Requirements Operating System • Windows XP, SP3 (32/64−bit) • Windows Vista, SP1 (32/64−bit) • Windows 7 (32/64−bit) • Microsoft .NET Framework 4.0 Driver Setup USB drivers should be installed automatically with the software. Once installed, you can plug the LIN Interface into the USB port. The hardware should be installed automatically and following message should be displayed: Hardware requirements 1 GHz 512 MB 850 MB (32−bit system) 2 GB (64−bit system) • Monitor resolution − minimum 800 x 600 pixels • USB port • Processor • RAM • Disk Space (The minimum disk space requirement is based on Microsoft .NET Framework 4.0 system requirements) Figure 6. Found New Hardware Message http://onsemi.com 4 NCV7430GEVK LIN Commands Tab The installation can be checked in Device Manager. When the hardware is connected, you should be able to find USB Serial Converter A and B in Universal Serial Bus controllers group. In case you encounter any problem with the drivers, try installing the drivers manually. The drivers can be found on http://www.ftdichip.com/Drivers/D2XX.htm − D2XX drivers − also available as executable file. The LIN commands tab has two functions. It monitors all the LIN bus traffic and allows sending a custom frame. Transmitted or received commands are listed in a table together with a time stamp and description of the frame. In the Frame Creator group box, fill all the necessary fields and click the Data transfer button to send the custom frame. Figure 7. LIN Commands Tab MISC Settings Tab The last Misc settings tab is used to set LIN baud−rate and additional OTP programming actions: Figure 8.
