Understanding Power Stability Issues with VBOX HD Lite.
Fluctuations in the power supply can cause VBOX HD Lite units to reboot as they require a steady 12 V power source at all times, even during engine cranking. If the voltage momentarily drops to 7 V or lower, the unit may enter a reboot cycle indicated by a rapidly flashing green LED. Additional symptoms of this issue include a "No Comms" error message on a connected OLED display or failure to record files to the MicroSD card in the device.
Workarounds to Prevent Rebooting
To help address this issue, you can consider the following solutions:
-
Power Cycling: Temporarily resolve the issue by disconnecting and reconnecting the Hirose power connector after the engine is running. Although effective, this approach may not be convenient for regular use, particularly while driving.
-
Rewiring to a Stable Power Source: For a more permanent fix, you can rewire the VBOX HD Lite unit's power supply directly to a stable source, such as the vehicle's main battery. This helps prevent voltage drops during engine cranking. Make sure that you include a 2.5 Amp fuse for safety and consult a qualified auto-electrician for proper installation.
-
Installing an In-line Switch: Another option is to install an in-line switch in the power circuit. By keeping the switch off until the engine has started, you can avoid voltage drops during cranking. Once the engine is running, simply turn the switch on to power VBOX HD Lite without disruption.
-
Using an External Battery Pack: For complete isolation from the vehicle's electrical system, consider using our RLACS333-H battery pack. This external battery powers the VBOX HD Lite independently, eliminating any reboot issues due to engine cranking.
