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:
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. |

ANDWhen 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. |
|
ORWhen 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. |
