The passwords block supports reading and writing Admin and User strings to the device that are used as passwords in ASIControl.

The password interface is a block control which is in turn an implementation of a universal control (see Universal Control).

Data types

The list of supported datatypes is as follows:

entity_type_cstring

ASCII character.

Passwords

Passwords

General purpose output block

Admin

Use this parameter to read and write the administrator password

User

Use this parameter to read and write the user password
