Other valid configuration settings for use in the config.txt file .

MassStorageEnable provides an alternative to a hardware lock on VTAP readers where jumpers may be difficult to access, but there is an enabled host connection via serial or USB.

NFCDefaultEnable allows the VTAP reader NFC field to be turned on or off to manage power consumption. StartupDelayMS provides a delay during start up to allow power to fully stabilise, for use primarily in situations with a Wiegand interface.

Settings below: MassStorageEnable | NFCDefaultEnable | StartupDelayMS| ZmodemRxTimeout

MassStorageEnable
Definition:

Allows a remote host to completely remove or restore mass storage access to VTAP readers with a config.txt setting. An alternative to a hardware lock, which avoids the need for changes to jumpers on the PCB, which may not be readily accessible.

Options:

Default value is enabled.

If the value is set =0 when there are no command interfaces on any other serial ports, on reboot the setting will be ignored (treated as if it were =1), to avoid becoming locked out of your VTAP reader.

Default value: =1
Example value: =0
NFCDefaultEnable
Definition:

Determines whether NFC is enabled [default] or disabled at startup, in order to manage power consumption.

Options:

In the example NFC will be disabled at startup, to save power.

Default value: =1
Example value: =0
StartupDelayMS
Definition:

Delay in milliseconds before fully starting up to allow the power supply to stabilise.

Options:

Use a value such as 5000 when using an external power supply.
This could prevent possible file system corruption during installation, if VTAP could be wired up to a live external power supply (typically when using Wiegand or RS-485 expansions).

Default value: =1000
Example value: =5000
ZmodemRxTimeout
Definition:

Set the receive timeout to an appropriate duration.

Options:

Number of milliseconds

Default value: =1000
Example value: =2000
