Correct termination is essential for reliable CAN network performance. In a recent install on a Kenworth Truck J1939 network, the initial scope trace showed no data while the Senquip device reported CAN errors. After installing a 120 Ohm termination resistor at the Senquip device, full diagnostic data was restored.
CAN network termination is the key to a dependable J1939 communications.

Modbus Chaos
One of the biggest frustrations with Modbus! Floating point numbers. Modbus only defines 16-bit registers—it doesn’t specify how multi-register values like 32-bit or 64-bit floats should be formatted. Different manufacturers use different byte orders, leaving you with a puzzle to solve. 🔄 Big-endian or little-endian?🔄 Word-swapped or standard?🔄 IEEE 754 or custom format? If you’ve …
