National Instruments NI-9853 | High Speed CAN Interface Module

National Instruments NI-9853 is commonly referred to as a high-speed CAN interface module.

· CAN interface: The main communication interface of this module is the CAN (Controller Area Network) interface, which follows the CAN 2.0A and CAN 2.0B protocols and 

provides high-speed and reliable CAN communication functions. It supports standard and extended identifiers, enabling communication between devices in fields such as 

automotive and industrial control.

· Baud rate: Supports multiple baud rates, generally ranging from 5 kbps to 1 Mbps, and can be flexibly adjusted according to specific application requirements to meet the 

requirements of CAN bus systems with different speeds.

· Electrical characteristics: It usually has good electrical isolation characteristics, which can prevent electrical interference between different devices and ensure the stability 

and reliability of communication. In industrial environments, electrical isolation can prevent communication errors caused by electrical noise or grounding issues.

· Physical interface: Using standard DB9 or DB15 interfaces, it facilitates physical connection with the CAN bus, and users can easily use standard CAN cables for connection.

· Message buffer: It has a certain number of message buffers used to store CAN messages received and sent. Generally, it can store tens to hundreds of messages, depending 

on the specific configuration of the module, which facilitates the temporary storage and processing of data.

· Timestamp function: Accurate timestamps can be added to each CAN message, which is very useful for applications that require precise time information. For example, in 

automotive electronic systems, timestamps can accurately record the time of event occurrence, which is helpful for system fault diagnosis and performance analysis.

· Data transmission rate: Supports high-speed data transmission, can quickly send and receive data on the CAN bus, and ensures timely transmission of information in systems 

that require frequent information exchange, such as vehicle power system control and distributed control of industrial equipment.

· Transmission delay: With low transmission delay, it ensures that data can be transmitted on the CAN bus in a timely manner, which is crucial for some applications that require 

high real-time performance, such as anti lock braking systems (ABS), electronic stability programs (ESP), etc., requiring fast response and data transmission to ensure system 

performance and safety.
