Benefits and Features

Supports various CAN modes

Uses latest Philips Can controller

Can be used in many networking applications, including vehicle testing

Technical Description

CANbus data can be stored (and synchronized) with other data values measured directly by the datalogger, allowing testing and verification of CANbus-based data alongside measurements made independentlviya the datalogger's input channels. The SDM-CAN also supports transmission of data onto a CANbus network.

The SDM-CAN uses the latest Philips SJA1000 CAN controller clocked at 16 MHz; CAN 2.0A and 2.0B active and passive modes are supported, which includes SAE J1939. The

CANbus protocol is used in a numbeorf networking applications, including vehicle data acquisition systems (VDAS).

The SDM-CAN can act as a passive “listen-only” device, poll remote devices for data, or act as a sensor. To poll remote devices it sends or responds to Remote Frame Requests. It acts as a sensor by sending data packets to the CANbus network. The SDM-CAN supports baud rates up to 1 MB (1 M, 800 k, 500 k, 250k, 125k, 50k, 20 k, and lower). Non-standard baud rates may be possible. CAN data frames can also be built and sent.

The datalogger enables individual modules through an addressing scheme; up to 15 SDM-CANSs can be connected to one datalogger.
