NI-XNET Single Wire hardware uses either the NXP AU5790 or ON Semiconductor NCV7356 Single Wire CAN transceiver.

NI PCI-8513 and NI PCI-8513/2 software-selectable NI-XNET PCI CAN interfaces (revision D and higher) use the ON Semiconductor NCV7356 Single Wire transceiver, while revision C (and lower) uses the NXP AU5790 Single Wire transceiver.

NI PXI-8513 and NI PXI-8513/2 software-selectable NI-XNET PXI CAN interfaces (revision E and higher) use the ON Semiconductor NCV7356 Single Wire transceiver, while revision D (and lower) uses the NXP AU5790 Single Wire transceiver.

To identify the your PCI/PXI NI-XNET hardware revision, refer to the 19xxxx<rev>–4xL text on the green label in the top left corner on the secondary side of the board; <rev> indicates the hardware revision.

The NI-XNET Single Wire hardware supports baud rates up to 33.3 kbps in normal transmission mode and 83.3 kbps in High-Speed transmission mode. The achievable baud rate is primarily a function of the network characteristics (termination and number of nodes on the bus), and assumes bus loading as per SAE J2411. Each Single Wire CAN port has a local bus load resistance of 9.09 k between the CAN_H and RTH pins of the transceiver to provide protection against the loss of ground. NI-XNET Single Wire hardware also supports advanced power management through low-power sleep and wake up modes. Refer to the NI-XNET Session Interface:CAN:Transceiver State property for more information.
