Vehicle Spy

To use neoVI PRO in Stand Alone mode, you must first create setup files in Vehicle Spy. Basic Vehicle Spy skills can be learned by completing Vehicle Spy Tutorials 1, 2, and 3. (Tutorials and many helpful examples can be found in the Vehicle Spy Help Documentation.) These tutorials encourage familiarity with the Vehicle Spy user interface as well as teach skills such as monitoring messages, transmitting messages, decoding signals, and constructing function blocks.

While using neoVI PRO for Bus Decoding, familiarity with the Message Editor view and signal setup will be especially important. Message Editor is accessed by selecting “View” from the menu at the top, then “Vehicle Networks”, and then “Message Editor”. The signals you setup here will appear in the Available Signals list in neoVI PRO.

[pic]

Figure - Use Message Editor in Vehicle Spy to setup messages and signals.

Keep in mind that the Vehicle Spy 3 Setup file is always running no matter what option you select. For example, in "Bus Decoder Mode" you can still have Function Block scripts and Function Block logging operational.

neoVI PRO Setup

neoVI PRO Setup is where you select your operation mode and may transfer files to and from the neoVI PRO device. neoVI Setup can be found by clicking on “Tools” in the upper menu and then selecting “neoVI PRO Setup” (Figure 2). Simply choose the desired operation mode from the drop down list.

[pic]

Figure 2: Access neoVI PRO Setup through Tools Menu.

[pic]

Figure 3: Choose neoVI PRO Operating Mode from Drop Down List.

neoVI PRO Emulator

The neoVI PRO Emulator is a useful tool for trying out your setup file before actually loading it in your neoVI PRO. The Emulator is found by clicking on “Tools” and then “neoVI PRO Emulator”. (See Figure 2.) Anything you set up in Vehicle Spy will work in neoVI PRO just as it does in the Emulator. Just use your mouse to click the buttons!

[pic]

Figure 2: Access neoVI PRO Emulator through Tools Menu.

Once you are satisfied with your setup file, you will need to send it to neoVI PRO. Do this by selecting the "Send Setup to neoVI PRO" option in the Tools menu. (See Figure 3.)

[pic]

Figure 3: Send Setup to neoVI PRO.

Loading

Loading your completed setup file: After completing your setup in Vehicle Spy 3, click on “File” and then “Save” and save your setup file. Copy this file to the neoVI PRO Compact Flash Card using a high speed card reader (perfect for large files), the USB port, or to serial ports. You may copy multiple files to the compact flash card. The number of files allowed depends on file size and capacity of card.

Notes: The communication ports on neoVI PRO have their useful limits. For example, the USB port has a transfer rate of about 110KBytes per second. Therefore, you should not try to transfer very large files > 5MBytes with it (5000KB/110KB = 45 Seconds). The best way to transfer very large files is to use a compact flash reader (Preferably USB2.0 based). Most all setup files are very tiny (50K or less), however, so changing setup files should never be a problem.

Setup Files & neoVI PRO Compact Flash

Changing Setup Files: neoVI PRO contains a file called “default.txt”. This file contains the name of the last setup file used. By default, each time you power up neoVI PRO, it will load the last setup file used. If you wish to use another setup file on the compact flash card, you must press and hold the [pic]button for 5 seconds. A list of available setup files will appear. Use the directional pad to highlight the desired setup file and then press [pic]button. This new selection will now become the default setup file.

Skipping Default Setup File: During initial power up, you can skip loading the default setup file by pressing and holding the [pic]button.

Removing the neoVI PRO Compact Flash: The Compact Flash in neoVI PRO is not hot swappable. Therefore you power down the neoVI PRO when reinserting the compact flash.

Errors

Vehicle Spy Errors are indicated by an Error Log Screen. This error screen appears anytime Vehicle Spy receives errors (for example: an invalid setup file). Click [pic]or [pic]to clear screen. When you clear the Error Screen, Vehicle Spy will also clear the Error Log.

The Text API

In stand alone mode you can access the Text API from the USB and serial ports. The text API allows complete control over Vehicle Spy 3 running in neoVI PRO.

You can control almost every object in neoVI PRO with the Text API. For example, to start function block 1 you can send the text "fb(0).start". See the Intrepidcs API documentation for more information on the Text API.

Powering neoVI PRO

The neoVI PRO will remain operational from 4.5V to 32 V. The bus functions may not operate correctly under 6V or physical layer transceiver limits.

The neoVI PRO power supply is not designed to operate continuously (more than 30 seconds) under 8 V. It supports lower voltages so that Crank and Motor stalls common in the vehicle do not affect operation. Therefore, a 9V or higher power supply is recommended. No damage will occur to the neoVI PRO at any voltage under 32V.

You can power neoVI PRO from either the power jack or the db25 connector or both.

Temporarily Entering Vehicle Spy Mini Mode

You can temporarily enter Vehicle Spy Mini mode at any time by holding the [pic]button for 5 seconds on the summary screen. This will allow you to determine if your scripts are running properly in the field. To return to your original mode press [pic]for five seconds at the Vehicle Spy summary screen.

[pic]

Figure : Temporarily Entering VSPY Mini Mode.

Setting the neoVI PRO Real-Time Clock

The neoVI PRO has a real-time clock that is used to timestamp the data. This clock can be set using the neoVI PRO setup in the Vehicle Spy software. The time setup is available via the Utilities tab. This tab is only available after you connect to neoVI PRO.

Unsupported Vehicle Spy Features and Performance

At this time, the neoVI PRO software supports all of the features of Vehicle Spy except for databases.

Also, you may find that very large files do not perform as well on neoVI PRO as they do on the desktop. In our tests, neoVI PRO performs well when you have 50 or so objects, scripts, and messages. 

Power Management

neoVI PRO can be automatically powered down when there is no network traffic. This is useful in situations where neoVI PRO is connected to a vehicle for long periods of time. The power down function is setup in the neoVI PRO setup. The power down current of neoVI PRO will vary between 15 and 25 mA depending on which networks you setup to wake up on.

|[pic] |Bus Decoder (Normal Mode) |

Overview

As previously mentioned, the Bus Decoder operating mode takes signals and converts them to voltages. These voltages are put out on specified pins, ready to be measured with standard measuring devices. Some standard measurement device includes data acquisition equipment, voltmeters, and oscilloscopes.

[pic]

Figure A-1: Bus Decoding

Standard Setup Procedure:

1) Create a Vehicle Spy Setup file using Vehicle Spy.

a) Open Vehicle Spy.

b) Select Tools and then neoVI PRO Setup.

c) Select “Bus Decoder (normal)” from the dropdown.

d) Open Message Editor (click on View, Vehicle Networks, and then Message Editor).

e) Add messages and decode signals. Make sure signals include Min and Max Ranges. Vehicle Spy uses these values to scale to voltage.

f) Open neoVI PRO Emulator (click on Tools and then neoVI PRO Emulator).

g) Verify that signals setup in Message Editor are listed in the Signal Selection Screen. Attach signals to specific channels. For more detail on this, see next topic below.

2) Save setup file. Go to File and then Save.

3) Copy your file to neoVI PRO’s compact flash card.

[pic]

Figure A-2: Signals Setup in the Message Editor are displayed in neoVI PRO.

Standard Screens and How to Maneuver

1) Analog Output Summary: This screen lists available analog outputs, 1 through 10. If no signal has been associated with an output, it will read “No Channel Selected”. If a signal has been selected, the signal name will be listed here. Use the directional pad to move up and down in the Analog Output Summary list. The output selected will be highlighted in blue.

[pic]

Figure A-3: Analog Output Summary List

2) Press the [pic]button to select an output. If a signal is selected, you will see a Channel Summary Screen. Please see labeled figure below for details.

[pic]

Figure A-4: Channel Summary Screen

While viewing a channel summary, use the directional pad left and right buttons to view scaling for different voltages. (Easily set up you DAQ system!)

Use the directional pad up and down buttons to scroll through channels without returning to the Analog Output Summary screen.

3) If an output with “No Channel Selected” was selected, the Channel Summary Screen will ask you to press the [pic]button once more. An Available Signals Screen will open, displaying all signals setup in the Message Editor. Maneuver through the list using the directional pad and then press the [pic]button to select a signal for the output.

[pic]

Figure A-5: Available Signals Screen

*At any time, pressing the [pic]button will take you back to the previous screen.

Where the Voltages Go: The Analog Output Connector

The voltages for each channel are present on the db15 connector on neoVI PRO.

[pic]

Figure A-6: The Analog Output Connector Pin out

The analog outputs are 0-5V outputs. The analog outputs all share an isolated ground wire so they can be wired to a single end measuring system without causing grounding problems.

Please see diagrams below for connection to common DAQ systems.

[pic]

Figure A-7:Connection to single ended measurement system.

 

[pic]

Figure A-8: Connection to differential measurement system.

Specifications and Theory of Operation

The neoVI PRO runs Vehicle Spy normally. This includes reading hardware, decoding messages, processing diagnostic jobs. Every loop time (2 milliseconds), all analog outputs are calculated and updated. The analog output calculation uses the latest value of the signal.

The signal value is scaled to the analog outputs as follows. First, if the signal is not valid because the message was never received the output will be zero. If the signal is valid it will be scaled so that its min and max are scaled to the 0.5 to 5.0v range.

[pic]

Figure A-9: The Analog Output Scaling Equation

For example, if the signal temperature's minimum is -40, the voltage output at -40 will be 0.5V.

Signals are scaled to 0.5V offset to allow you to determine signal validity from the voltage signal. If the voltage is less than 0.5V you know immediately that your data is invalid.

[pic]

Analog Output Calibration

The Vehicle Spy software offers a utility for calibrating the analog outputs.

|[pic] |Bus Decoder (J1979 mode) |

Overview

As previously mentioned, the Bus Decoder operating mode takes signals and converts them to voltages. These voltages are put out on specified pins, ready to be measured with standard measuring devices.

J1979 Mode differs from Normal Mode in that the user does not have to set up signals in Vehicle Spy’s Message Editor. Signals are already defined by SAE J1979. Also, the request messages required for J1979 are automatically supplied. Finally, the type of network neoVI PRO is connected to is automatically determined. The networks supported are CAN bus, J1850 PWM, J1850 VPW, Keyword 2000, and ISO9141.

Standard Setup Procedure:

1) Create a Vehicle Spy Setup file Using Vehicle Spy.

a) Open Vehicle Spy.

b) Select Tools and then neoVI PRO Setup.

c) Select “Bus Decoder (J1979)” from the dropdown.

d) Open neoVI PRO Emulator (click on Tools and then neoVI PRO Emulator).

e) Verify that signals are already listed in the Signal Selection Screen. Attach signals to specific channels. For more detail on this, see “Normal Mode: Standard Screens and How to Maneuver”

2) Save the setup file. Go to File and then Save.

3) Copy your file to neoVI PRO’s compact flash card.

[pic]

Figure B-1: Operating Mode selected in neoVI PRO Setup

J1979 Mode: Standard Screens and How to Maneuver.

Please see “Normal Mode: Standard Screens and How to Maneuver” on previous page.

Signal Update Rate

Each signal in J1979 mode is requested. No more than 1 request is allowed at a time. Therefore your update rate will depend on how many signals you are monitoring. It will also depend on the BUS used - i.e. CAN is a lot faster than ISO9141. It can also vary on the vehicle. J1979 mentions 100 ms per channel as the minimum that an OEM must support.
