SOURCE GROUPING, CONTINUED
Over fifty (0 99) source groups are available. Each video input is allocated to only
one of these source groups.
During commissioning, each video output channel may be allocated to some or all of the
fifty groups for selection. At least one source group must be allocated.
Note:
Only cameras from the allocated source groups
(for a given video output channel can be selected and
displayed on that video output channel.
2.9
CHANNEL ACCESS BY KEYBOARDS
In order to structure the control of a large video switching system (i.e. 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 video output
channels (monitors etc.).
Each keyboard has its own identification number (1 99). The keyboard ID numbers
are allocated to each video output channel during commissioning. Only the allocated
keyboards are allowed to access and select video sources (cameras etc.) on that video
output channel.
Where the video output channel is a monitor, only the allocated keyboards will be able to
select that monitor for use. 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.
Note:
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.
2.10 SYSTEM ACCESS BY OPERATORS
In any video system, several different operators can use any one keyboard. To maintain
the confidentiality and security of the video system, these system operators would be
assigned different levels of system access.
Each system operator has 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/her. Operators' system access is programmable by
setting the appropriate flags in the system's configuration editor (the SETMAX program
is discussed in detail in
Chapter 6
).
