DGPS/RTK #

Differential GPS (DGPS), or Differential GNSS (DGNSS) as it is also known, is a system that provides positional corrections to GNSS signals. DGNSS uses a fixed, known position to adjust real-time GNSS signals to eliminate pseudorange errors. You can set up your own base station, use an already set up base station, or use an NTRIP modem to provide these correctional messages to your VBOX unit.

If you need information about how to set up your Base Station, you can find it here .
  1. Connect the Radio Antenna to the DGPS Client Radio.
  2. Place the Radio Antenna on the vehicle roof.

VBOX 4 units must have the correct DGPS mode enabled via the VBOX Setup Software before it is capable of receiving and using the DGPS correction information transmitted by a Local Base Station or an NTRIP service.

Using with Local DGNSS Base Station #

2 cm positional accuracy:

If you use VBOX 4 ADAS with a Base Station (RLVBBS5 or RLVBBS6), the positional accuracy will increase to 2 cm.

  • RTCM v3 - 2 cm correction (RTCM standard message type) RECOMMENDED
  • Racelogic - proprietary 2 cm correction
  • CMR - 2 cm correction (Trimble standard message type)

RTCM v3 is recommended as the default RTK 2-cm correction type. This message format is a globally recognised type and is more resilient to data loss caused by radio errors.

RTK #

The receiver automatically detects the format of the differential corrections (RTCM or CMR) and switches between standalone, DGPS or RTK modes according to the type of corrections it receives.

Setup using VBOX Setup #
  1. Run the latest VBOX Setup software.
  2. Select the correct COM Port and go to the GNSS menu.
  3. Go to the DGPS option and select the correct DGPS mode and baud settings from the available options.
  4. Select Write to unit to upload the new settings to the VBOX 4 unit.
Solution typelookup #

0 = None

GNSS receiver cannot compute a solution for position.

1 = GNSS only

Position computed from GNSS only.

2 = GNSS DGPS

Position computed from assisted GNSS, this includes SBAS and Base Station DGPS corrections.

3 = RTK Float

Position computed from GNSS corrected by RTK. Float means the GNSS receiver is still calculating the integer ambiguity, a small error will be present on the position computation at this time.  

4 = RTK Fixed

Position computed from GNSS corrected by RTK. Fixed means the integer ambiguity is established and the optimum position correction is applied resulting sub 2 cm relative accuracy in good conditions.

5 = Fixed position

GNSS receiver position is fixed/locked. This is primarily used for Base Station receivers.

6 = IMU Coast

Position computed from the Kalman filter when GNSS is lost, inertial data from the IMU is used to maintain a solution for position until the GNSS is re-established. 

VBOX 4 has four isolated CAN ports that can be configured and used for a variety of applications:

  • RL CAN
    Used for connecting Racelogic modules and displays.
  • CAN
    Used for input and/or output of CAN 2.0 frames. 
  • CANFD 1
    Used for logging the raw CAN FD or CAN 2.0 bus to an .ASC file.
  • CANFD 2
    Used for logging the raw CAN FD or CAN 2.0 bus to an .ASC file.
RL CAN #

You can use the CAN port to log data from a vehicle or sensor CAN bus or transmit CAN data to a third-party system. VBOX 4 units can log up to a maximum of 32 channels through this CAN 2.0 port.

Configuring CAN Port #

You can configure the CAN port in the CAN menu in VBOX Setup.

You can read more about how to configure the CAN port here.

Logging CAN Data #

VBOX 4 can log up to 32 channels from external CAN sources on the CAN port. 

You can select the relevant CAN signals in VBOX Setup. Go to the Channel Setup menu and expand the CAN Input section. You can add signals from the Racelogic Vehicle CAN Database, by loading a .DBC file or by entering them manually.

Transmitting CAN Data #

VBOX 4 can transmit VBOX data via CAN to third-party systems.

You can select the messages you wish to send via CAN on the Transmitted Identifiers tab in the CAN menu.

Bus Loading

If the bus loading is more than 70%, the icon in the top right corner will become red. When it is more than 75% the icon will start flashing. If you choose to write to the unit while the CAN bus loading exceeds 70%, you will trigger a warning message.

CAN Pass Through #

You can output additional channel data from the RL CAN port (i.e. data from a Racelogic module) on the CAN port by using the CAN Pass Through functionality. You can select messages for output using the available signal dropdown list, and configure the identifier as required.

VBOX 4 can output up to 8 user-configured CAN messages and up to 16 CAN signals on the CAN port.

CAN FD1 / CAN FD2 #

VBOX 4 units have 2 separate CANFD ports that you can use to capture data from 2 separate buses. 

The CANFD 1 and CANFD 2 ports are input only and can accept either CAN 2.0 or raw CAN FD.
 

You can enable Full bus logging on the CANFD port and configure the CANFD settings in the CAN menu in VBOX Setup.

If you enable Full bus logging on the CANFD ports, but do not enable CANFD logging, the CANFD ports will log CAN 2.0 only.  

If you enable CANFD logging, VBOX 4 will log the full vehicle bus to a time-synchronised .ASC file that will open alongside the .VBB file in VBOX Test Suite.

You can see the pinout information for the Analogue Input Connector here.

VBOX 4 contain four differential 24-bit analogue input channels with a maximum sample rate of 500 Hz. Each channel has a dedicated analogue to digital (A/D) converter with all four channels being sampled synchronously to each other. The voltage range of the input channels is ± 50 V.

The analogue input connector also contains voltage outputs that can be used to power external sensors. These are a Vbatt connection that equals the VBOX unit's input voltage level and a 5 V DC out connection that equals 5 V ± 2%.

  • The 5 V out connection is electrically isolated, allowing for a current draw of up to 120 mA.
  • The Vbatt connection is internally protected by a thermal fuse of 300 mA.

A screw-terminal connector block is available as an option for easy connection of signal pins.

By using the VBOX Setup software, you can change the name of each input channel and configure scale and offset values to calibrate sensors.

A scale value of 1 and an offset of 0 correspond to a channel reading in V DC. This means that the value stored on the memory card for the channel will also be in volts.

When using a sensor such as a load cell, it may be desirable to store readings in kg. In this case, changing the scale and offset to suit the sensor data sheet allows the data stored on the compact flash to be in kg.

When changing settings for an analogue channel in the VBOX Setup software, you can see a live data view of the current channel. The value shown is the value after scale and offset are applied and can, therefore, be used to aid sensor calibration.

500 Hz logging

VBOX 4 units can log 4 analogue channels at 500 Hz. You can enable 500 Hz logging for internal analogue and digital inputs by clicking the 500 Hz logging for internal A/D toggle switch in the Logging menu in VBOX Setup.

Brake Trigger / Event Marker / Log Switch #

The D IN port on VBOX 4 contains two digital inputs. You can connect one directly to the D IN port or use a splitter to connect 2 simultaneously. 

  • The Handheld event marker input connects to an event capture input on the GNSS engine. This will precisely capture the trigger event time (at 10 ns resolution). A handheld event marker is also available so that you can record marker events in the data file.
  • You can use a Remote logging on/off switch to manually start/stop data logging for ease of use and in situations when the front panel button is not accessible.
  • By using a Brake Pedal Trigger, a physical pressure switch on the brake pedal, you can capture a precise ‘start of braking event’.

You can connect 2 digital input devices to the VBOX 4 with the use of an additional Splitter (RLVBACS027), as shown in the example image below.
