Number of CAN Nodes
The maximum number of nodes depends on the electrical
characteristics of the nodes on the network. If all of the nodes meet
the requirements of Low-Speed/Fault-Tolerant CAN, up to
32 nodes may be connected to the bus.
NI 9852 Hardware Overview
The NI 9852 has two full-featured, independent CAN ports that are

that is CAN 2.0B-compatible and fully supports both 11-bit
and 29-bit identifiers. Each port also has a Philips TJA1054A
