Important
- Do not remove the CF card or power down whilst the CF LED is flashing. If you need to remove the
card or power down whilst the CF LED is flashing, then press the LOG button first to stop the VBOX logging.
Failure to do so will result in data loss or corruption.
FUNC
Pressing the FUNC button briefly flashes the LED’s and beeps to indicate the current sample rate. A slow flash (once
per second) on all the LED’s indicates 20 Hz, and rapid flashing (5 times a second) indicates a 100 Hz sample rate. A
running sequence of lights indicates a sample rate other than 100 Hz or 20 Hz. Pressing and holding the FUNC button
for 5 seconds toggles the current sample rate. The sample rate can also be set using VBOX Manager or VBOX Setup.
Default setup
The default factory settings are restored to the VBOX by pressing and holding the FUNC and LOG buttons for 5
seconds. This will put the VBOX 3i into the default factory settings; 100 Hz log rate, log continuous mode, Fixed 20 ms
CAN delay, Output CAN Tx Identifiers on, Racelogic CAN on the CAN port, customer VCI CAN on the SER port, and
only standard GPS channels and brake trigger event time set to log.
VB3i RS232 / CAN Ports
for information on the VB3i RS232 protocol.
VBOX 3i is equipped with 2 CAN Bus interfaces and 2 RS232 serial ports. The primary RS232 port is used for all
communication between the VBOX and laptop PC. The primary port is marked SER on the VBOX 3i front panel. The
primary RS232 port (SER) is able to transmit live data from the VBOX to the PC for viewing and performing real-time
tests. It is important to note however that due to limitations of the PC serial port, live data transfer of all channels is
limited to 20 Hz, at 50 Hz only standard GPS channels and Solution Type should be transmitted, and at 100Hz only
Sats, Time, Speed, and Trigger Event Time should be transmitted. Logging too many channels at too high a rate is likely
to cause drop-outs and loss of data.
Therefore for maximum accuracy, tests performed at a GPS sample rate above 20 Hz should be logged to compact
flash and post processed.
Note that when the VBOX is set to an ADAS mode, RS232 serial transmit from the SER port will be disabled.
The secondary RS232 port is used for connection to a Telemetry Radio module allowing the reception of Differential
GPS (DGPS) data for local correction from a Racelogic Local DGPS basestation, or Moving Base solution. The
secondary RS232 port is located in the connector marked CAN on the VBOX 3i front panel.
