setup), the monitor outputs being used as Trunk lines
are automatically disabled from local control as soon
as the first commands are received from the main
site.
If operators will be stationed at the satellite site,
camera titles should be entered into the switcher. If
desired, these titles can be selected (explained
below) to appear at the main site.
The only other requirement is to ensure that the
Console ports of all Allegiant type satellites have
their handshake option disabled (CTS = off). This is
done via the GUI software, the MCS's Parameters-
System screen, or via the system's Keyboard User
Functions (as described later in this manual). This
requirement does not apply to TC8112B/TC8124B
Series switchers.
Main Site Programming Requirements
At the main site, the GUI or MCS program's Camera
ID table must be configured to ensure proper satellite
operation. Usually it is easiest to start with the Trunk
line inputs. For each Trunk line, the satellite's
monitor output number and its 'Bay' address (the
same number the satellite's TC8780 Series unit is set
to) must be entered.
Camera numbers should be programmed next. Note
that no duplicate camera numbers are allowed
anywhere in the entire system. Remote cameras
(those located at the satellite sites) should be
designated using
corresponding to the main bay's physical video
inputs (32+ on TC8300, 65+ on TC8500, 129+ on
TC8600, 257+ on TC8800). Enter the desired
camera number, the Satellite Bay that it is actually
connected to, and select if either a local title will be
used or if the remotely generated title will be used.
For the satellite camera entries, only those numbers
which
numbers above those
represent
actual cameras need to be entered. For example, all
12 cameras associated with a 12-position TC8112B
switcher do not need to be entered if only 5 cameras
are actually connected to the switcher. If desired, a
few extra camera numbers may be included at this
time if the satellite site will be expanded in the future.
If a local title is specified, the camera's title can also
be entered at this time. Designate any local camera
numbers appropriately and enter their corresponding
titles. Note that either a local camera or a remote
camera programmed with a local title will need to be
selected to view certain on-screen prompts or data
during programming of the main site via a system
keyboard.
Once the system is programmed and configured, any
unused monitor outputs (those with no physical
monitors connected to them) located at the main site
should be selected to display a local camera via the
system keyboard. This prevents unused monitor
outputs from using up Trunk lines which may result in
some confusing operational responses.
Alarm Inputs in Satellite Systems
Any alarm inputs to the main site which have been
programmed to activate cameras located at satellites
will operate in the 'normal' way except when limited
by the number of Trunk lines available. The software
will automatically determine Trunk usage depending
upon the priority level of operators currently viewing
satellite cameras. Note that alarm inputs applied
at a satellite site will NOT activate alarm video at
the main site. If the application requires alarms
located at a satellite to activate video at the main
site, then the remote alarms must be brought back to
the main site. In some cases, the main site's
TC8540C Alarm Interface unit can be remotely
located via a RS-232 link. If more than one satellite
site contains alarms, then multiple TC8540C alarm
interfaces can be remotely located. The number of
alarm interfaces which can be remoted is only limited
by the capacity of the main site system to support
this capability.
