Bus Waveform



Below you’ll find maps, schedules, and stop lists for each of Wave Transit’s fixed bus routes. Please note that not all bus stops are included on the maps, only the ten (10) major stops are listed. Most routes provide service to about 40 bus stop locations. Click on “Stops” next to each route for a complete listing of bus stops or call Wave Transit at 343-0106 for complete stop information. This page utilizes pop-up windows. You may have to adjust your browser settings or disable any pop-up blockers in order to view the schedules, etc. Do you have a suggestion for a bus stop location?

The purpose of this test is to investigate the presence of LIN-BUS signals and circuit integrity in relation to systems connected.

  1. Revision 2.2 xi Figures Figure 1-1: PCI Local Bus Applications.
  2. An oscilloscope allows the engineer to examine the analog bus waveforms to evaluate signal quality and noise, as well as study multiple signals to look for interactions and identify crosstalk. The CAN bus requires 120 Ω termination. An unterminated bus will result in poor signal quality (upper signal).
  3. For some odd reason, Quora may be warning that this answer has “sensitive images”. The most common serial buses in use today are:. USB - Universal Serial Bus: most common external serial interface today. I2C.

How to perform the test

Virtual Buses-A virtual bus is a grouping, or “folder”, to which logic scalars and arrays can be added. A virtual bus displays the icon and virtual bus name. The virtual bus displays a bus waveform, which is comprised of the signal waveforms in the vertical order that they appear under the virtual bus, flattened to a one-dimensional array.

View connection guidance notes.

  1. Use manufacturer's data to identify the LIN-BUS circuit and connected components.
  2. Connect PicoScope Channel A into the LIN-BUS circuit and to a good earth.
  3. Minimize the help page. You will see that PicoScope has displayed an example waveform and is preset to capture your waveform.
  4. Start the scope to see live data.
  5. Operate the systems connected by the LIN-BUS to observe signal changes. Move connectors and wiring loom fixings to look for any signal drop-out.
  6. With your waveform on screen stop the scope.
  7. Use the Waveform Buffer, Zoom and Measurements tools to examine your waveform.

Note:

LIN-BUS circuit access can be gained at individually controlled components.

Example waveform

Waveform notes

As you can see from the example waveform, the LIN bus waveform is a square wave, representing the binary states in a serial data stream. The waveform observed should be free of obvious distortion and noise spikes, and the upper and lower levels should be approximately as in the example (for a 12 V system).

The lower level voltage (logic zero) should be less than 20% of battery voltage (typically 1 V) and the upper level voltage (logic one) should be more than 80% of battery voltage. Note that the voltage levels may change slightly when the engine is started.

Spi Bus Waveforms

We cannot decode the data stream using a scope, so the purpose of this test is to verify that the signal is both present and correct, and is not interrupted by moving the wiring harness or gently tugging the connectors. Faults may be specific to a particular function, such as a non-operating window, or general, where all the functions on the bus are not working. Before condemning a device, use the scope to check that it has power, ground, and a present and correct LIN signal.

Further guidance

Local Interconnect Network (LIN) bus communication is becoming more common on modern CAN Bus-equipped vehicles. It is essentially a low-speed, single-wire serial data bus (a sub-bus of the faster, more complex CAN Bus) used to control low-speed non-safety-critical housekeeping functions on the vehicle, especially windows, mirrors, locks, HVAC units, and electric seats.

The LIN bus is proving popular because of its low cost and also because it reduces the bus load of the supervising CAN network.
