The Yokogawa 720241 CAN/LIN Bus Monitor Module is a plug-in instrument for decoding and analyzing Controller Area Network (CAN) and Local Interconnect Network (LIN) bus signals in automotive electronic systems. It captures up to 60 signals simultaneously and displays physical parameters—engine temperature, vehicle speed, brake-pedal position—as analog waveforms correlated with sensor readings. The module features isolated dual-port connectivity: one CAN port rated to 10 V and one LIN port rated to 18 V maximum measurement voltage. With a 100 kS/s sample rate, it supports real-time signal monitoring and troubleshooting of vehicle control networks.

– Key Features
• Dual isolated bus interfaces enable simultaneous CAN and LIN monitoring without cross-channel interference
• 100 kS/s acquisition rate captures transient behavior and fast signal transitions
• Support for up to 60 decoded signals per measurement session
• Physical parameter decoding displays actual vehicle data rather than raw bus frames
• Waveform correlation overlays sensor data with bus signals for root-cause diagnostics
– Typical Applications
• Powertrain and emission control system troubleshooting
• Body electronics and comfort feature diagnostics
• Chassis control network validation
• Vehicle electronic module communication verification
• CAN/LIN signal integrity and timing analysis
– Compatibility & Integration
The 720241 integrates as a plug-in module into Yokogawa ScopeCorder instruments: DL850V, DL850EV, DL350, and DL950 models. A maximum of two bus monitor modules (including the 720240 module) can be installed per ScopeCorder unit.
Product Status: This module was discontinued by the manufacturer as of March 31, 2024. The 720245 CAN Bus + LIN Monitor Module is the available replacement.
