5. Device Configuration

Your IVNT-03 ships from the factory ready to use with its default settings. However, its operation can also be customized to your exact needs by adjusting dozens of parameters that control its internal hardware and firmware. In this chapter, we’ll show you how to manage and fine-tune your IVNT-03, including enabling and disabling networks, adjusting baud rates, turning on or off specific features, and much more.

5.1. Starting neoVI Explorer Directly with Vehicle Spy 3 Installed

The neoVI Explorer utility allows you to connect to, manage and configure all of your Intrepid Control Systems hardware, including the IVNT-03. It is supplied both as an integrated feature of Vehicle Spy, and as a standalone program.

This section will describe general features and the basics of using neoVI Explorer, so you will understand the utility well when we get into settings specific to the IVNT-03.

Starting neoVI Explorer from within Vehicle Spy

There are several ways to open neoVI Explorer from within VSpy. These are probably the two easiest, since they are accessible at all times:

  1. Menu Item: Click the Setup menu and then select Hardware.
  2. Hardware Setup Button: Click the button located in the main Vehicle Spy toolbar just under its menu.

Note

Note: You cannot start neoVI Explorer when Vehicle Spy is online (even if in simulation mode). If you attempt to do so, VSpy will prompt you to either go offline and launch neoVI Explorer, or remain online and return to Vehicle Spy.

Starting neoVI Explorer as a Standalone Program (with Vehicle Spy Installed)

If you want to work with your IVNT-03 without opening Vehicle Spy, you can launch neoVI Explorer directly. Open the Start Menu, navigate to the IntrepidCS folder, then under the Vehicle Spy subfolder, select neoVI Explorer.

Starting neoVI Explorer as a Standalone Program (API Kit Installed)

If you installed the API kit and support files instead of Vehicle Spy, you can run neoVI Explorer from the Start Menu using the same basic process as described above. The only difference is the name of the subfolder, so you will navigate to the IntrepidCS folder, then open the ICS API Install Kit subfolder, and finally select neoVI Explorer.

Connecting to the IVNT-03

When neoVI Explorer loads, it will start up with the first hardware device it can find selected in the menu pane on the left. You should see your IVNT-03 listed here, along with its serial number, which begins with “CY”. If you don’t see the IVNT-03, but do see other Intrepid devices, be sure to scroll down to look for it. If it is still not visible, either its drivers have not been installed correctly or it is not powered properly; please refer to Chapter 7 for assistance.

To manage your IVNT-03, click on its entry in the navigation pane (if it is not already highlighted) and then press the Connect button. After successfully connecting to the device, you will see a “thumbs up” icon next to the device’s name, and checkmarks will appear next to currently-enabled networks in the explorer area on the left. You should also see a message in the message box on the right saying IVNT-03 CYxxxx settings have been read. This tells you that neoVI Explorer has loaded the current settings from the IVNT-03. The information in the upper right-hand part of the window is device-specific and described in Section 5.2.

Note

Note: It is possible to click on various parameter groups at any time, but they will not show valid data until you connect to the device. Remember also to connect to the device before making changes, or those alterations will be erased when you do connect and the settings in the hardware are loaded.

Writing and Reloading Settings

To avoid potential problems, neoVI Explorer will not save any changes to device parameters until you instruct it to do so. This is done by pressing the Write Settings button, which will update the parameters within the firmware in your IVNT-03. If you make changes you do not want to keep, pressing the Read Settings button will reload the settings stored in the device, wiping out any modifications made in neoVI Explorer that had not yet been saved.

Reloading Device Defaults

To return all settings to factory defaults, press the Load Defaults button. This is convenient if many changes have been made and written to the firmware in the past, and you want to start over with a clean slate.

Note: Pressing this button actually writes the defaults to the device first, and then reloads them automatically, so you do not need to also press Write Settings. You will see messages in the message area telling you that defaults have been sent to the device and then read from it.

Disconnecting from the IVNT-03

Press the Disconnect button to tell neoVI Explorer that you are done working with the IVNT-03. This step is actually optional, because neoVI Explorer will disconnect from any connected devices when you exit the program.

Searching for Devices

If you attach new hardware to your PC after starting neoVI Explorer, press the Search For Devices button at the bottom left of the dialog box to prompt the program to scan for new hardware you can manage.

Exiting neoVI Explorer

Like any Windows program, you can close neoVI Explorer by clicking the “X” in the top right corner, or pressing the Alt+F4 key combination.

5.2. System Settings and Firmware Updates

The top two entries in the explorer window on the left side of neoVI Explorer contain system-wide settings that apply to all hardware devices, and information related to firmware updates.

System Settings

Click here, and in the right-hand pane you will see four settings that you can enable or disable.

Enable Server: Turns on the neoVI Server feature, a background program that allows your hardware to be used by multiple applications at the same time.

Enable Low Latency: This is an advanced setting for applications where fast response is needed after transmission.

Enable Slave VNET Settings: This setting is used for the FIRE 2 VNet module used with a neoVI PLASMA or neoVI ION, and can be ignored for the IVNT-03.

Enable Auto Update: When enabled, both neoVI Explorer and Vehicle Spy will automatically update firmware. If this box is not checked, firmware must be updated manually (See below for details).

Available Firmware

This is an informational page that shows which firmware versions are available in this version of neoVI Explorer for various Intrepid products. Some devices have multiple firmware programs that control different aspects of their operation; in the case of the IVNT-03, these are called MCHIP and CCHIP.

You normally won’t need to look in this area, because as we’ll see in Section 5.3, neoVI Explorer shows you the current and available firmware versions for your IVNT-03 when you connect to it.

Updating Firmware Firmware is essentially software that runs hardware, and is required to enable the many capabilities of your IVNT-03. New versions of firmware are created regularly by Intrepid’s engineers to implement new features and correct problems that have been identified.

If you have Enable Auto Update on—which is the default, and is recommended—then you don’t really need to worry about firmware updates. Each time you connect to your IVNT-03 in neoVI Explorer or go online with it in Vehicle Spy, the firmware will be checked, and if a newer version is available, the device will immediately be updated. You will see dialog boxes on the screen showing you the progress of this operation, which takes only a few seconds. Note: While firmware updates are in progress, the device will be in bootloader mode, indicated by a “three green, one red” LED flash sequence. This will stop when the update is complete. Also, even if only one of the firmware components has a new version, both will be updated to ensure internal consistency in the IVNT-03.

If you do not have automatic updates enabled, you control when your firmware is updated. When new firmware is available, you will be notified on the initial connection screen. Simply press the Manual Reflash button to update the firmware. Again, you will see messages as both the CCHIP and MCHIP firmware programs are sent to the device, and a message will appear in the message box on the right to tell you that the process has completed.

Note: While firmware updates are in progress, the device will be in bootloader mode, indicated by a “three green, one red” LED flash sequence. This will stop when the update is complete. Also, even if only one of the firmware components has a new version, both will be updated to ensure internal consistency in the IVNT-03.

5.3. General Settings and Product Details

These two areas of the IVNT-03’s parameter setup provide information about the device and allow you to perform a few basic maintenance tasks.

General Settings

After connecting to the device you will see basic information about it in the right-hand pane of the window. Information that will be displayed includes:

  • The device’s serial number.
  • The firmware versions currently in the device, and an indication if new firmware is available.
  • A message showing that the hardware license for the device was recognized.
  • A current readout of the IVNT-03’s real-time clock.

This information can be displayed again at any time by clicking the IVNT-03’s name in the explorer navigation window, or the General Settings entry immediately below it.

The versions of the MCHIP and CCHIP firmware for the IVNT-03 will each be shown in black if they match the firmware versions within neoVI Explorer. If they do not, the current version and the newest available version will be shown in red to help you notice that an update is available. Section 5.2 provides more information on firmware updates.

There are four buttons on this screen. Two of them, Load Defaults and Manual Reflash, were described in Section 5.2. The Read RTC button will reload the device’s internal time clock, while Synchronize RTC will set the device’s clock to the same value as that of the PC.

Product Details

This is an informational area that provides technical data on the IVNT-03’s hardware and internal setup. You will generally only need this if requested by Intrepid in order to facilitate support or troubleshooting. You can use the Copy To Clipboard button to copy all of the information to the Windows Clipboard, so you can then paste it into an email or file.

5.4. Standard CAN Networks (HS CAN 1-5 and MS CAN)

This area of neoVI Explorer is used to enable, disable and configure the six standard dual wire CAN networks in theIVNT-03: High Speed CAN channels 1 to 5 (HS CAN and HS CAN2-5) and the Medium Speed CAN channel (MS CAN). Each channel has an entry under the “CAN” group (which cannot be clicked itself). The current status of each channel is shown next to its name; a green checkmark indicates that the channel is enabled, while a red X means it is disabled. Figure 64 shows an example of the CAN channels area, with MS CAN and HS CAN4 currently disabled, and the other channels enabled.

All six of these channels have the same parameters, which can be configured using the controls in the right-hand pane.

Enabled

Place a checkmark in this box to enable the channel, or clear the checkmark to disable it. When disabled, all of the other parameter controls are disabled (grayed out).

Specify by Baud

This is a master control that determines whether the operation of the channel is controlled by a numeric baud rate, or is calculated from lower-level timing parameters. When checked, the Baud Rate and CAN FD Baud Rate drop-down boxes are enabled and the various TQ, Sync and BRP-1 entries are disabled. When unchecked, this is reversed.

Specifying by baud rate is the default, and is recommended except for advanced users with special requirements.

Baud Rate

When Specify by Baud is selected, choose a baud rate for the channel from the drop-down box below. The default value is 500000.

CAN Timing Settings

When Specify by Baud is deselected, the operation of the CAN channel is based on these five settings: TQ SEG1, TQ SEG2, TQ Prop, Sync, BRP-1. These settings are for advanced users and normally should be left at their default values.

CAN FD Baud Rate

When Specify by Baud is selected, choose a baud rate for the data phase of CAN FD messages. The default value is 2000000.

CAN FD Timing Settings

When Specify by Baud is deselected, use these settings (TQ SEG1, TQ SEG2, TQ Prop, Sync, BRP-1) for the data phase of CAN FD messages. These parameters are for advanced users and normally should be left at their default values.

Mode

  • The operating mode of the channel; choose from one of these four options:
  • Normal: Normal operation (default).
  • Disable: Channel is disabled.
  • Listen Only: This channel only receives messages, with no transmissions, and also no error frames generated nor acknowledgments sent.

Transceiver

The operating mode of the CAN transceiver: * Auto: The transceiver is automatically controlled by the CAN logic for the channel (default). * Enabled: The transceiver is always enabled. * Disabled: The transceiver is disabled.

Bit Rate Calculator

Press this button to launch the Intrepid Bit Timing Calculator.

5.5. Selectable CAN Networks

The 7th and 8th of the IVNT-03’s CAN channels are user-selectable: They can be set as additional High Speed (dual wire) CAN channels (HS CAN6 and HS CAN7), as Low Speed Fault Tolerant CAN channels (LSFT CAN and LSFT CAN 2), or as Single Wire CAN channels (SW CAN and SW CAN 2). Both channels must be set to the same mode (so you cannot have HS CAN6 and SW CAN at the same time, for example).

Selectable CAN Mode

The master control for these channels can be found by clicking on Selectable CAN. On the right hand side you will find a drop-down box; choose DW CAN, LSFT CAN or SW CAN depending on which CAN variant you want for these two channels. SW CAN is the default.

neoVI Explorer Selectable CAN Mode Control.

Based on your selection, neoVI Explorer will automatically enable the corresponding two channels in this group and disable the other four. You can manually override the enabled channels if, for example, you only want one of the two. You cannot, however, override the disabled channels, as they are physically disconnected within the device when your selection is made. (If you listen closely after changing the selection here and clicking Write Settings, you may even hear a relay click as the change is made in the hardware).

DW CAN (HS CAN 6 / HS CAN 7)

When DWCAN is selected, two additional High Speed CAN channels are turned on. Their parameters are identical to the six standard CAN channels described in Section 4.4, and are configured in the same way.

LSFT CAN (LSFT CAN / LSFT CAN 2)

When LSFT CAN is selected these two channels are enabled. They have the same basic settings as the standard CAN channels, except that there are no CAN FD settings (since CAN FD is not supported on LSFT CAN). The default baud rate for LSFT CAN channels is 125000.

SW CAN (SW CAN / SW CAN 2)

With SW CAN chosen under Selectable CAN, the Single Wire CAN channels are enabled. These have the same settings as the standard CAN channels, with the following changes:

  • No CAN FD section (CAN FD is not supported on these channels).
  • The Transceiver drop-down box has additional options: High Voltage and High Speed.
  • The High Speed Auto Switch option tells the channel to switch to high speed mode upon receipt of a specific message.
  • The default baud rate is 33333.

LIN Networks (LIN1 to LIN4)

This section of the IVNT-03 explorer tree allows you to enable, disable and configure its four LIN channels, LIN1 to LIN4. Each channel has an entry under the “LIN” group. As with the CAN channels, a green checkmark indicates that a particular channel is enabled, while a red X means it is disabled.

All of these channels have the same parameters. In this image we have selected the Advanced Options checkbox to display its options (described below).

Enabled

Place a checkmark in this box to enable the channel, or clear the checkmark to disable it. When disabled, all of the other parameter controls are disabled (grayed out).

Baud Rate

Select a baud rate for the channel; the default is 10417.

Mode

This option is currently not used and should be left at the default of “Normal Mode”.

Master Resistor On

Enable this option for the IVNT-03 to act as the master on the specified LIN bus.

Advanced Options

Click this check box to reveal two additional options

  1. Master Slave Interval: The time between the master ID and the first slave byte, in bits (default 0).
  2. Verbose Error Reporting: When checked, break errors and other error messages from the LIN driver are displayed.

5.6. Other Parameters

In addition to the network-specific parameters described above, there are a number of additional option sets that you can use to tailor the operation of your IVNT-03.

ISO 15765-2

This page contains one setting: IFS Shift Register. Changing this from its default value of 0 causes time to be added to the Inner Frame Spacing of USDT frames transmitted by CoreMini scripts running in the IVNT-03. The number entered is multiplied by 6.4 µs to determine the time offset. The allowed range is -1563 to 1563.

Text API

These parameters control the operation of the text API that can be used to operate the IVNT-03 using third party software. Please contact Intrepid if you require assistance with using the API.
