The TRC-8543 is designed to provide flexibility in connecting a CAN bus to the NI-9860, PXIe-8510, and/or the native NI-XNET port on a cDAQ-9134 or cDAQ-9135 controller. You can connect the TRC-8543 to the port to support a CAN HS/FD or LS/FT interface. The TRC-8543 is an isolated cable that includes the necessary transceiver for the bus type. It also features termination resistors that you can enable or disable in software.
