Features:

• Supports data communication and conversion between RS232/485/422 and CAN interfaces.
  
• Complies with CAN 2.0B specification (extended frame), compatible with CAN 2.0A specification (standard frame); conforms to ISO 11898-1/2/3.
  
• CAN baud rate: 10 kbps to 1000 kbps, configurable
  
• Supports 14 configurable filters, can only receive CAN bus data in a specific range and type
  
• Supports 4 operating modes: transparent conversion, transparent conversion with identifiers, format conversion and Modbus RTU protocol conversion
  
• Up to 1000 frames CAN buffer for buffering transmission data to prevent data loss
  
• Integrated unibody power supply isolation, provides stable isolated voltage, does not require additional power supply for the isolated connection
  
• Integrated unibody digital isolation, enables signal isolation, high reliability, strong anti-interference, low power consumption
  
• Integrated TVS (Transient Voltage Suppressor), effectively suppresses overvoltages and transient voltage spikes in the circuit, lightning and electrostatic protected
  
• Integrated 15 kV ESD insulation protection and 600 W lightning and surge protection
  
• Integrated 120R termination resistor on the RS485/RS422 port, configurable via jumper
  
• Supports device firmware upgrades via RS232/485/422, simplifying firmware customization
  
• Supports setting of operating parameters via configuration software or serial commands, saves settings after power off
  
• Integrated screw terminal for power supply, allows a wide input range from 5 V to 36 V DC
  
• 4 LEDs to display power and transceiver status
  
• Industrial-grade metal housing, supports wall and rail mounting, solid and elegant, easy to install
