Synchronization in USB-CAN/LIN Devices

USB-847x with Sync series hardware give you the ability to synchronize multiple NI-USB-CAN/LIN devices with each other and with a variety of DAQ, IMAQ and Motion Products. Synchronization occurs through a 3-pin Combicon connection allowing for a shared timestamp clock, start trigger and ground. USB-847x with Sync series hardware can synchronize to timestamp clocks of 20 Mhz, 10 Mhz, or 1 Mhz. For 20 MHz synchronization, ensure that the synchronization cable is shielded and grounded. Clock frequency is detected automatically by the hardware and illegal clock frequencies will be reported as an error. USB-847x with Sync series hardware can also generate a clock of 1MHz, allowing for accurate CAN-CAN, CAN-LIN, and LIN-LIN synchronization.
