IMPORTANT NOTES ABOUT STARTUP
NOTE 1: The Guard Unit, when powering the MDS installation
of which it is part, needs time to initialise correctly and for the
MDS Central Unit to detect and configure it as a Guard Unit.
This is why,when the power source is connected to the
MDS system at first, the Guard Unit shows no information on
the display. To indicate that it is initialising, its LED blinks
during this 25-second period. (*).
NOTE 2: The Guard Unit has a number assigned, which must
correspond to the number of the MDS switcher where it is
physically connected. (0..9). To change this number, which is
0 by default, keep the # key pressed until a question mark
appears on the display. Enter the number of the desired Guard
Unit, to which the system will respond with OK. Once the
Guard Unit number has been changed, the system must be
rebooted so that the MDS Central Unit can recognise it.
(*)
In certain circumstances, this time can be reduced, such as in case
that, after initialising the Guard Unit correctly beforehand, we disconnect
it from the MDS BUS, but without cutting off the power from the rest of the
MDS System. When the Guard Unit is reconnected again, you can dispen-
se with a considerable part of the initialisation time by pressing the BELL
key after connecting the Guard Unit. In this way, initialisation is reduced to
around 5 seconds.
