USB
When you connect the Audio sensor to the PC with the USB-A to USB-C cable, the unit will be powered by the PC via the cable so that you can see the live preview of the audio around you and configure the unit.
CAN
You can use a RLCAB005-C cable to connect the Audio Sensor to a VBOX unit to relay the live trigger data via CAN to the VBOX unit. You can see more information about the CAN message output here.
TRIG OUT
You can use the RLCAB007-2 cable wired to the Analogue Input connector to connect the Audio sensor to the VBOX unit. This will send the live trigger data to the VBOX unit via the Analogue Input.
There are multiple connection methods for the Audio Sensor:
The RLCAB007-2 is an unterminated cable that you can wire into a Sub-D 25-way connector to connect to the A IN port on a VBOX 3i unit.
Use the RLCAB005-C to connect from the CAN/PWR port on the Audio Sensor to a CAN port on the VBOX 3i unit.
This is an accessory that is to be used when the sound you are listening for comes from a location that is hard to reach.
- Make sure that you have VBOX Audio Sensor Setup installed on your PC.
- Connect your ADAS Audio Sensor to your PC with a USB-A to USB-C cable.
This cable will power the unit and provide access to configure the detection and trigger settings.

- When the software has connected to the unit, the graph in the Visualiser will automatically populate and show live feedback of background noise captured by the Audio Sensor's internal microphone (or external microphone if used).
- Select the frequency you wish to detect.
You can do this by either clicking directly on the graph to select that frequency, typing the frequency directly into the Selected Freq. (Hz) value box, or using the arrow buttons next to the Selected Freq. (Hz) value box to increase or decrease the frequency value. - You can replay the selected frequency in the software to confirm your selection by clicking on the speaker icon next to the selected frequency in the Visualiser.
- Click on the + icon next to the Selected Freq. to add the currently selected frequency to the Frequencies to Detect list.
You can add a maximum of 4 frequencies to detect.
- You can set the unit to trigger using the AND or OR functionalities:

AND
When you select AND, the signal detection will only be triggered when all of the frequencies are met simultaneously. You can use this for multi-toned warnings or multi-vibration haptic warnings.
Using AND triggering will significantly reduce false positives from any background noise.

Using AND triggering will significantly reduce false positives from any background noise.

OR
When you select OR, the sensor output will be activated when the unit detects any of the configured frequencies. The Audio Sensor’s CAN bus output contains individual data bits for each frequency. This makes it possible for a connected VBOX 3i unit to establish and highlight which vehicle warning sound has been detected. For example, if it is a seat belt reminder or a Forward Collision Warning.
Additionally, it is common for warnings to rise in both frequency and intensity the longer they have to sound. (Such as the seat belt reminder or the warning cascade described in UNECE R79). The multiple frequency option with OR triggers will give you the ability to measure individual timings in the escalation of warning sounds.

This is an accessory that is to be used when the sound you are listening for comes from a location that is hard to reach.
To use the VBOX Audio Sensor with a VBOX data logger, you must first configure the Audio sensor to trigger on the required frequencies and then configure the input from the Audio Sensor to the VBOX data logger. This is to make sure that it is picking up the required signals and that they are logged correctly.
Click on the images below to see the information about how to configure your Audio Sensor:
You can connect the ADAS Audio Sensor as a Racelogic module to VBOX 4 ADAS with the RLCAB005-C CAN cable.
A Racelogic Module will automatically be recognised by VBOX Setup and added to the list of connected modules in the Channel Setup Menu where you can select the channels you want to log.
VBOX 4 ADAS: Connect one Lemo connector to the RLCAN port on the VBOX 4 ADAS unit and the other connector to the CAN/PWR port on the Audio Sensor.
If you require a different input method for VBOX 4 or to connect to another VBOX product, you can find the full mounting and installation information here.
