Halaman Cetak4 Hardware lock to prevent firmware or configuration
change
You can lock the VTAP100 so that its firmware and configuration cannot be changed. You can either
do this in software or hardware.
A software lock leaves some files visible. A hardware lock means that the VTAP100 will no longer be
detected as a composite USB device.
You can use a hardware lock provided the jumper labelled LOCK (close to the MicroUSB connector)
remains accessible on a VTAP100-OEM.
Connect a jumper across LOCK on the PCB to lock the device, preventing firmware or configuration
changes.
Figure 4-1 Jumper positions on VTAP100 PCB V3a
When you start the VTAP100, the presence of this jumper means the connected PC will not detect a
USB mass storage device. The VTAP100 will only be detected by the PC as a keyboard (or keyboard
and virtual COM port).
At any time you can remove the jumper across LOCK. When you restart the VTAP100 it will be
detected as a USB mass storage device and you will be able to make firmware or configuration
changes again.
