5. The neoVI Explorer Configuration Utility
5.1. Starting and Using neoVI Explorer
This section will describe general features and the basics of using neoVI Explorer. It is the utility is used to connect to, manage and configure all of Intrepid Control Systems hardware. It is an integral part of Vehicle Spy, but for those not using Vehicle Spy software, it is also available as a stand alone application in the free ICS Hardware Installation kit
5.1.1. 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:
Menu Item: Click the Setup menu and then select Hardware.
Hardware Setup Button: Click the button located in the main Vehicle Spy toolbar just under its menu (Figure below).
Note
neoVI Explorer cannot be launched when Vehicle Spy is online (even if in simulation mode). Attempting to do so, VSpy will display a prompt to either go offline and launch neoVI Explorer, or remain online and return to Vehicle Spy.
5.1.2. Starting neoVI Explorer as a Standalone Program
neoVI Explorer can be opened as as standalone program. The location of the shortcut to launch neoVI Explorer differs slightly between a Vehicle Spy installation and the ICS Hardware Installation kit as shown in the following screen captures.
5.2. Interfacing with a device
5.2.1. Connecting to a device
When neoVI Explorer loads, it will start up with the first hardware device it can find selected in the menu pane on the left. Any connected devices should be listed here, along with its serial number. If a particular device is connected, but not seen among a list of other Intrepid devices, be sure to scroll down to look for it. If it is still not visible, this means its drivers have not been installed correctly, it is not powered properly, or there is a problem with the connection to the host computer.
To manage a device, 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, a “thumbs up” icon will be displayed next to the device’s name, and checkmarks will appear next to currently-enabled networks in the explorer area on the left. A message in the message box on the right will also read “<Your Device and Serial Number> settings have been read”. This indicates that neoVI Explorer has loaded the current settings from the unit.
The screen as a whole should appear similar to the screen shown below (but note that the device and version number shown below may be different).
Note that this screen varies in content between Intrepid devices.
Searching for Devices
After attaching new hardware to a PC and 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 to be managed.
Note
It is possible to click on various parameter groups at any time, but they will not show valid data until connected to the device. Remember also to connect to the device before making changes; Any changes made in neoVI Explorer with no device connected will be overwritten by a devices settings when it is connected.
5.2.2. Device Configuration
Writing and Reloading Settings
To avoid potential problems, neoVI Explorer will not save any changes to device parameters until instructed it to do so. This is done by pressing the Write Settings button, which will update the parameters within the firmware in the device. If unwanted changes were made, 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 Default Settings button. Note that pressing this button actually writes the defaults to the device first, and then reloads them automatically, so it is not necessary to also press Write Settings. The message area will display that defaults have been sent to the device and then read from it.
Disconnecting from the device
Press the Disconnect button to tell neoVI Explorer disconnect the device. This step is actually optional, because neoVI Explorer will disconnect from any connected devices when the program is closed.
Exiting neoVI Explorer
Like any Windows program, neoVI Explorer can be closed by clicking the “X” in the top right corner, or pressing the Alt+F4 key combination.
5.3. 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.
5.3.1. System Settings
In the top branch of the tree in the left pane of neoVI Explorer there are several settings that can be enabled or disabled:
Enable Server: Turns on the neoVI Server feature, a background program that allows the 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 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.)
Network Adapter Server: This is a feature that is used with Intrepid products having Ethernet ports. (It may not apply to your device.) With This feature enabled, the Ethernet ports on Intrepid hardware will enumerate as network interfaces in the operating system of the host computer. This server can be started and stopped in this window. There is also a checkbox to configure the server to start after booting of the computer.
5.3.2. Available Firmware
This is an informational page that shows which firmware versions are available in this version of neoVI Explorer for various Intrepid products. Note that some devices have multiple firmware programs that control different aspects of their operation;
5.3.3. Automatic and Manual Firmware Updates
Warning
While a device may appear to operate with incompatible firmware, proper and reliable operation cannot be guaranteed unless the version of firmware matches what is listed in Vehicle Spy
Firmware is essentially software that runs inside hardware and is required to enable the many capabilities of a device. New versions of firmware are created regularly by Intrepid’s engineers to implement new features and correct problems that have been identified.
Enable Auto Update is on by default and is recommended for most users. Each time a device connects neoVI Explorer or Vehicle Spy, the firmware will be checked, and if a newer version is available, the device will immediately be updated. If automatic updates is not enabled, it can be updated manually as needed. When new firmware is available, a red notification will be displayed on the initial connection screen, as shown below. Simply press the Manual Reflash button to update the firmware.
Note that this screen varies in content between Intrepid devices.
5.3.4. The Firmware Update Process
During the firmware update process, the device will be placed into bootloader mode, indicated by all LEDs on the top label flashing synchronously. Normal LED flash patterns will resume when the update is complete and the device reboots. The progress of the firmware update operation is displayed in a dialog box as shown below. A message box on the right side of neoVI Explorer will also be displayed as the firmware program is sent to the device. When the process is complete the dialog box will disappear and another message will appear in neoVI Explorer to confirm that the update has finished. If any error messages are displayed or any other problems experienced updating the device’s firmware, please contact Customer Support for assistance.
Warning
Please take heed of the warning on the firmware update dialog box: leave the device connected and powered on for the entire firmware update process to avoid possible problems with the device.
5.4. General Settings and Product Details
These two areas of the device’s parameter setup provide information about the device and can be used to perform a few basic maintenance tasks.
5.4.1. General Settings
After connecting to the device, basic information about it will be displayed in the right-hand pane of the window:
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 device’s real-time clock.
This information can be displayed again at any time by clicking the device’s name in the explorer navigation window, or the General Settings entry immediately below it.
The version(s) of the firmware for the device will be shown in black if it matches the firmware version within neoVI Explorer. If not, the current version and the newest available version will be shown in red to highlight that an update is available. (See the previous section for more about the update process.)
There are three buttons on this screen.
Manual Reflash (described in the previous section)
Read RTC button will reload the device’s internal time clock
Synchronize RTC will set the device’s clock to the same value as that of the PC.
5.4.2. Product Details
This is an informational area that provides technical data on the devices’s hardware and internal setup. This is generally only needed this if requested by Intrepid in order to facilitate support or troubleshooting. The Copy To Clipboard button can be used to copy all of the information to the Windows Clipboard to be pasted into an email or file.
5.5. Logger Settings (optional)
For devices with the optional logging capability, This checkbox disables logging when data is being extracted from the device.
5.6. Storage Disk (optional)
For devices with the optional logging capability, this interface is used to format the internal logging NVM and view its current status and details.
5.7. SerDes
Note
SerDes is currently not available
5.8. CAN Network Settings
5.8.1. CAN Networks
This area of neoVI Explorer is used to enable, disable and configure the High Speed CAN channels. 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. The figure below shows an example of the CAN channels area, with HS CAN enabled and HS CAN2 disabled.
All of the CAN channels have the same parameters, which can be configured using the controls in the right-hand pane; the default settings are shown 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).
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.
Bit Rate Calculator: Press this button to launch the Intrepid Bit Timing Calculator.
5.8.2. ISO15765-2:
This page contains one setting: IFS Shift Register (shown below). 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 FIRE 2. The number entered is multiplied by 6.4 µs to determine the time offset. The allowed range is -1563 to 1563.
5.9. LIN Network Settings
This section the device’s explorer tree allows enabling, disabling and configuring its LIN channels. Each channel has an entry under the “LIN” group (seen below). 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, which can be seen below. 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 device to act as the master on the specified LIN bus.
Advanced Options: Click this checkbox to reveal two additional options:
Master Slave Interval: The time between the master ID and the first slave byte, in bits (default 0).
Verbose Error Reporting: When checked, break errors and other error messages from the LIN driver are displayed.
5.10. Ethernet Port Configurations
5.10.1. 1000BASE-T1 Active Tap
The primary use case for RAD-Gigastar is a 1000BASE-T1 Active Tap. As the diagram depicts below, the ports are connected internally such that any traffic that ingresses on AE1 will egress on AE2, and vice-versa. In addition, all ingressing traffic on both ports is mirrored to the host PC connection port for use with VSPY or Intrepid’s open source APIs.
By default, the Active Tap works in a “Store & Forward” mode, where the entire frame must ingresses on one port before starting to egress on another. This is normal operation for many Ethernet devices such as switches that need to check for frame errors before forwarding to the next destination. Enabling Cut-Through mode will allow the frame to start egressing a on this screen will eliminate most, but not all of this latency
5.10.2. Independent Ports
In this mode, all 4 ports can be used independently to transmit and receive messages using VSPY or Intrepid’s open source APIs.
5.10.3. SFP/1000BASE-T1 Active Tap
This mode of operation is nearly identical to the 1000BASE-T1 Active Tap, but the tap pairs are AE1/SFP1 and AE2/SFP2.
5.11. PHY Configurations
5.11.1. 1000BASE-T1 PHY Configuration
From this screen the 1000BASE-T1 PHYs can be configured
Enabled: Each port can be independently enabled/disabled.
Preemption Support: This must be enabled to work with the fragments of preempted frames in VSPY. Reference IEEE 802.1br for more information.
Enable MAC Spoofing: When enabled, this feature will change MAC address of an Ethernet passing through the active-tap on the fly. Spoofing can be done on either the source or destination MAC address. The specific MAC address to be spoofed must be specified as well as the spoofing address.
Link Speed: The speed can be set to 100Mbps, 1Gbps, or enable auto-negotiation in the PHY. When set to “auto”, not only is link speed negotiated, but the master/slave setting as well.
Link Mode: The behavior of this setting depends on the link speed configuration.
When the link speed is set to 100Mbps or 1Gbps, this will configure the PHY as master or slave. The PHY itself does not have the means to negotiate master/slave without also negotiating link speed. Therefore, the “auto” setting for link mode is accomplished by firmware alternating master/slave until a link is made with the other PHY.
When the link speed is set to auto, master/slave is typically negotiated as well, but selecting master here will override any negotiation and force the link mode to master. The slave and auto settings here have no effect when the link speed is set to auto.
PHY Mode: In most cases, this should be set to IEEE mode to link with all 1000BASE-T1 PHYs in compliance with IEEE requirements. Legacy mode is a setting only intended for Marvell 88Q2112 A0 and A1. Legacy mode will also link with another 88Q2112 A2 PHY also set to Legacy mode.
5.11.2. SFP Configurations (BASE-T)
Enabled: Each port can be independently enabled/disabled.
Link Speed / Duplex: The available settings may vary based on the PHY within the SFP.
Enable Device Hosting: This setting enables the ability to host other ICS hardware connected to an SFP for logging purposes.
Enable TCP/IP: This setting enables the ability to host Axis Cameras for logging purposes.
5.11.3. SFP Configurations (BASE-T1)
Enabled: Each port can be independently enabled/disabled.
Link Speed / Duplex: The speed can be set to 100Mbps, 1Gbps, or enable auto-negotiation in the PHY. When set to “auto”, not only is link speed negotiated, but the master/slave setting as well. Note there is no half-duplex mode in BASE-T1 networks.
Enable Device Hosting: This setting enables the ability to host other ICS hardware connected to an SFP for logging purposes.
Link Mode: The behavior of this setting depends on the link speed configuration.
When the link speed is set to 100Mbps or 1Gbps, this will configure the PHY as master or slave. The PHY itself does not have the means to negotiate master/slave without also negotiating link speed. Therefore, the “auto” setting for link mode is accomplished by firmware alternating master/slave until a link is made with the other PHY.
When the link speed is set to auto, master/slave is typically negotiated as well, but selecting master here will override any negotiation and force the link mode to master. The slave and auto settings here have no effect when the link speed is set to auto.
PHY Mode: In most cases, this should be set to IEEE mode to link with all 1000BASE-T1 PHYs in compliance with IEEE requirements. Legacy mode is a setting only intended for Marvell 88Q2112 A0 and A1. Legacy mode will also link with another 88Q2112 A2 PHY also set to Legacy mode.
Enable TCP/IP: This setting enables the ability to host Axis Cameras for logging purposes.
5.12. gPTP Time Synchronization
This device supports Generalized Precision Time Protocol as defined in IEEE 802.1AS. It can be configured to use the Standard profile or the Automotive profile as defined by the Avnu Alliance.
Note
Since this device is not a switch, only a single port may be enabled to support gPTP. This port may serve as a Grandmaster or as a clock slave to sync the device clock to a Grandmaster.
Typically the timestamp Physical Hardware Clock (PHC) of your device is synchronized with a host computer when connected. In cases where it is desireable for this clock to be synchronized with another clock source, gPTP can be enabled. The clock is automatically synchronized to Epoch Time when enabled and it is connected to a gPTP grandmaster.
Note
Erratic behavior may be observed if the Epoch Time of logged messages is prior to 1/1/2007.
gPTP is configured in the following interface.
Note that this screen varies in content between Intrepid devices.
5.12.1. gPTP Settings
gPTP Endpoint Port |

Offset Scaled Log Variance: Attribute defining the stability of a clock |
|
Priority 2: 0-255, lower value = higher priority |
5.13. ICS Time Sync
If multiple ICS devices are being used to log networks in parallel, the internal clocks used to timestamp the logged traffic can be synchronized in order to provide time-aligned logs. The following screen is used to configure this clock synchronization.
The devices synchronize using a private CAN network between them. This means no other DUTs or ECUs should be connected to this private CAN network. Each device must be configured from this screen to select which CAN network should be used for synchronization as well as if it is the clock master for all of the loggers or it is a clock slave.
Note
Exactly one device needs to be configured as a clock master when synchronizing clocks between multiple ICS loggers.
5.14. Reporting
This setting enables the reporting of the RAD-Gigastar SoC temperature and cooling fan speed.
5.15. Network Enables
Networks of the RAD-Gigastar can be enabled and disabled from this checkbox interface.
5.16. Performance Tests
The following are tests which can be used to characterize the bandwidth and latency between ICS hardware and its host computer. If problem is encountered with either of these, our Customer Support would be happy to help resolve it. Reference the end of this document for contact information.
