NI 9852 Hardware Overview
The NI 9852 has two full-featured, independent CAN ports that are isolated from
each other, and from the other modules in the system. Each port on the NI 9852 has
a Philips SJA1000 controller that is CAN 2.0B-compatible and fully supports both 11-
bit and 29-bit identifiers. The port also has a Philips TJA1054A Low-Speed/Fault-
