I am planning on using the USB-8476 LIN interface as the LIN bus Master in an application. The application would require the USB-8476 (Master) to program a Node ID and Zone ID into a slave device that is on the LIN bus. The slave device is a PIC12F1822 mcu + MCP2021 LIN transceiver. After reading through the User/Software Manual for the USB-8476, it does NOT seem possible to assign an ID to a slave device. It seems like you can only communicate with slaves that already have an ID programmed into their memory. The Node/Zone ID terminology is used by our customer and may not conform exactly to the IDs associated with LIN. I am new to the LIN world, so please let me know if you need more information about what I'm trying to accomplish. Can you program a Slave's Node ID or Zone ID using the USB-8476 as the LIN Master?

No need to respond to this topic. The company that builds the slave device has a communications specification that was recently provided to me. I should be able to use the NI USB-8476 and a call to the ncWrite function (NI-CAN Frame API function) to accomplish my goals.

Good to hear!
