Configuring the meter for a Read Only user allows data or configuration items to be viewed but not
changed. This level of authorization might be appropriate for general end-users, such as building
owners, who may not be aware of the details of the installation. It is recommended to use ViewPoint HD
to configure permissions, although it is also possible to set up a Read Only PIN using the PSHD Web App
if a Read/ Write PIN has already been entered (either through the LCD user interface or the PSHD Web
App itself).

Read/Write permissions allow users to read and write configuration items and to reset the PINs. This
level of authorization will be required by any technician or user who needs the ability to correct setup
errors in the meter. The default PIN [0000] allows a new user to reset the Read / Write PIN from either
the PSHD Web App or ViewPoint HD. Permissions cannot be set through the LCD interface.

ViewPoint HD can be used to directly report the Read Only and Read/ Write PINs under the Advanced
Tab (passwords). The value reported by ViewPoint HD is the value as entered in the web page or LCD
interface.
PINs are also accessible as Modbus registers but are encoded so that reading the value of the register
through an RTU does not inform a user what the password is. This feature allows DENT Instruments to
support retrieval of forgotten PINs if network access is available.

The ViewPoint HD software tool can be used to read and write configuration information to the meter
without entering credentials.
ViewPoint HD is the preferred tool for setting up access restrictions because it allows users to
test the function of the PINs without locking themselves out from the ability to change the PIN,
a frustrating catch 22!
