Power Supply
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.
Connection
There are multiple connection methods for the Audio Sensor:
Trigger Out
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.
CAN
Use the RLCAB005-C to connect from the CAN/PWR port on the Audio Sensor to a CAN port on the VBOX 3i unit.
External Microphone
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.
This page provides the steps for setting up the ADAS Audio Sensor with VBOX Audio Sensor Setup.

1. Make sure that you have VBOX Audio Sensor
Setup installed on your PC.
2. 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.
3. Open VBOX Audio Sensor Setup.
4. Click on the Connect button to open the dropdown
list of available COM ports and select the port that
you connected the Audio Sensor to. (It will be
labeled as USB serial device.)
5. 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).
6. 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.
7. 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.
8. 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.
9. You can set the unit to trigger using the AND or
3

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.
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.

10. Go to the Advanced Settings area to adjust the
following settings, if applicable:
Measure Background Noise Range
Noise Multiplier
Digital Output Fixed Delay (ms)
CAN Output
11. When you are happy with the configured settings, click Write to Unit to
save the configuration to your Audio Sensor unit.
