9.6 MONITOR ACCESS
To structure the control of a large video switching system (that is, a system with several
monitors physically located at different control locations) it is necessary to restrict the
control access that each keyboard can have over the available monitors.
Each keyboard has it's own identification number (1 Ù 32). The keyboard ID numbers
are allocated to each monitor during commissioning. Only the allocated keyboards are
allowed to access and select cameras on that monitor. This means that monitors that
are located somewhere other than at the control room where the keyboard is being
used, cannot be selected or controlled.
CAUTION: To use a keyboard, it must first, be signed-on
by an operator. Otherwise, it is rendered inactive and
cannot control any aspect of the video system.
9.7 SYSTEM ACCESS BY OPERATORS
In any video system several different operators can use any keyboard. To maintain the
confidentiality and security of the system, these system operators can be assigned
different levels of system access.
Each system operator can have a 4 digit Personal Identification Number (PIN). By
assigning different access levels, an unauthorized operator cannot access the areas of
the video system that are restricted to him or her.
CAUTION: In most systems the sign on feature is not
used. The keyboard generally uses its default operator,
which is programmed at commissioning.
