MasterCAN C 232/485 CAN Converter
The MasterCAN C 232/485 CAN Converter by Technoton is a professional vehicle data interface designed to convert information from CAN SAE J1939/71 networks into RS-232 and RS-485 communication interfaces.
It provides a practical solution when a telematics terminal, GPS tracker, PLC, controller or monitoring device needs access to CAN bus information but does not have a suitable native CAN interface.
CAN J1939 to RS-232 & RS-485 Conversion
The MasterCAN C 232/485 receives and processes data from the vehicle’s CAN network and makes the information available through serial communication interfaces.
Input:
- CAN SAE J1939/71
Outputs:
- RS-232
- RS-485
- ASCII
- Modbus RTU
- DUT-E COM
This allows vehicle and machinery operating parameters to be transferred to compatible telematics and monitoring equipment.
Vehicle Telematics Integration
The MasterCAN C 232/485 CAN Converter is particularly useful for integrating CAN bus information into GPS tracking and fleet management systems.
The converter can automatically scan and parse FMS messages from the onboard CAN SAE J1939/71 network and transfer the resulting information through RS-232 or RS-485. It can also calculate accumulated fuel consumption using CAN fuel-rate data where appropriate.
Typical Applications
MasterCAN C 232/485 is suitable for:
- Fleet management systems
- GPS vehicle tracking
- Heavy trucks and commercial vehicles
- Construction machinery
- Agricultural equipment
- Diesel-powered machinery
- CAN bus data acquisition
- Fuel consumption monitoring
- Remote equipment monitoring
- Industrial automation and IIoT systems
Flexible Configuration
The output interface can be configured for parameters including data type, transmission interval and baud rate. Technoton’s configuration options include Modbus RTU, ASCII and DUT-E COM output formats.
