I do not know about the Brailliant.  Some displays do allow to change
the PIN (I remember some little Baum device with a internal menu
that allowed that, but I forgot its name).  Some others
have a hardcoded PIN.  Even others do have PINs which are "mathematically"
related to the device serial number...

For those displays that always have the same PIN, that would
be the right thing to do IMO, yet another reason to implement this
functionality in the core.  However, the serial-numbers-make-up-the-PIN
devices would allow that too, but I am not sure it is in the interest
of the users and/or the manufacturing company to reveal that knowledge,
if it exists...
