WebAug 28, 2024 · In high-speed CAN bus, the ends must be terminated, but this doesn’t mean that signal reflections can’t still happen between the bus nodes. Stub length and node spacing must be carefully controlled; in particular, the stub length should be minimized, the node spacing should be randomized and respect a minimum distance. hillside service center lock haven paWebNov 19, 2016 · CAN- toggles from the 2.5-volt bias to 1.5 volts. CAN+ and CAN- added together equals a reference voltage of 5.0 volts. When both are displayed on a labscope, a CAN- waveform is the upside-down, mirror image of the CAN+ waveform.

The international organization … smart life thermometerWebThe bus signal is created electrically by applying a differential current into the two-wire bus system. By doing so, a differential voltage of 800 or 900 mVpp (where "pp" stands for "peak-to-peak") is generated on the bus. This is then also the nominal peak-to-peak amplitude (Vpp) of the signal that any Fieldbus device generates. hillside shooting
