Each MOV is identified by a unit number which it uses to identify the messages which
are sent to it on the remote communications line. This number can be between 1 and
255.
To prevent unauthorised persons from communicating with the relay via a
communications program and changing the settings or performing operations, the
relay has a password. This password can only be seen on the relay display and takes
the form of a number between 0 and 99999.
Set to 0 if the relay is not working in a DDS integrated system. Set to the maximum
time between two synch signals coming from the PC host, when the relay is working
in a DDS integrated system. If a new synch signal is not received in this time the
relay will report an error.
