CAN Bus Tool

Product Pictures And Documentation Showing The Usage Of The CAN Bus Tool

This CAN Bus Tool uses an LCD Touchscreen, an Arduino UNO and a Microchip MCP 2515 Stand-Alone CAN Controller to allow real time monitoring of 11-bit messages and 29-bit extended messages in a CAN V2.0B bus at up to 1 Mb/s. It can also be used to send 11-bit or 29-bit CAN messages with a payload of 0 to 8 bytes. 

Messages can be viewed in real-time or specific messages can be filtered by message identifier and message content. The bus speed can be dynamically changed to the following speeds: 5, 10, 20, 31. 25, 33, 40, 50, 80, 100, 125, 200, 250, 500, and 1000 kbps (1Mbps). 

The unit, in Normal mode, will send acknowledgment replies to each received message or it can be configured in Silent mode as Listen-Only and not send replies. There is a built in 120 ohm termination resistor that can be enabled and disabled with a jumper. 

In Silent mode with the 120ohm termination resistor disabled, this unit is invisible to other devices in an existing bus.
