Request Information

The RS-232 to CAN Converter with Two Digital Inputs is a compact device for interfacing RS-232 satellite phones or GPS systems with CAN bus in on-road commercial vehicles.

The RS-232 serial port interface is provided with user-configurable frame forwarding system to convert serial port messages into CAN frames. Likewise, the two fully isolated CAN interfaces have user-configurable CAN ID filtering and frame forward system, to convert CAN frames into serial port messages. By default, the primary CAN port (CAN1) supports J1939 messaging and uses passive baud rate discovery to detect CAN network baud rate.

In addition, two digital signal inputs are provided. The inputs can be configured to measure frequency, PWM and digital signals. Measured input data can be sent to a SAE J1939 CAN Network or used to enable/disable frame forwarding.

A Windows-based Axiomatic Electronic Assistant (EA) is used to configure the controller via a USB-CAN (AX070501) device. Setpoint configuration can be saved in a file which can be used to easily program the same configuration into another device of the same P/N.
