Satellite Site “Trunk Line”
Monitor Outputs
At each of the remote satellite sites, a desired
number of monitor outputs from the switcher must be
assigned as Trunk lines. The number of Trunk lines
can range from 1 to the maximum number of monitor
outputs that the switcher provides. Note that the
number of Trunk lines coming from a satellite site
determines the maximum number of different
cameras from that site that may be viewed
simultaneously at the Main site. If operators will be
stationed at the satellite site, they should be
prevented from accessing the monitor outputs
designated as Trunk lines. This can be accomplished
via the Monitor Lockout tables using either the
TC8850 Graphical User Interface Software package
or the TC8x59 Master Control Software package (see
below).
Main Site “Trunk Line” Video Inputs
At the main site, video Trunk line connections
coming from each of the remote site(s) should be
connected (and properly terminated) using any
available video input at the main bay. There are no
programming restrictions concerning their
connections, but a sense of order can be maintained
if a group of video inputs are used at the upper end
of the system’s designed capacity. This allows the
main system to be more easily expanded in the
future with either additional local cameras or
additional Trunk lines. As an example, assume that
there are a total of 8 Trunk lines coming from all
satellite sites which will be connected to a main site
system designed for 32 inputs. Inputs 25 to 32 can
be reserved for the Trunk lines leaving inputs 1 to 24
for local camera connections. If there will be no local
camera inputs, then the Trunk lines can start at the
first video input.
Control Data Lines in Satellite Systems
Each satellite site must be provided with an Allegiant
control data line coming from the Signal Distribution
unit (usually a TC8568) at the Main site. This data
line carries all pan/tilt/zoom control commands in
addition to the switching commands generated by the
Main site switcher. The control data line should be
connected to a TC8780 Series Data Converter unit
which will be used to provide the address decoding
functions for the satellite site. A TC8780 Series unit
is required at each satellite site and must be given a
unique site address number.
If operators will be stationed at the satellite site and
are permitted to control pan/tilt/zoom equipped
cameras, a TC8569-2 Series Code Merger unit must
be installed at the satellite site. The Code Merger will
combine the code generated by the main site and the
satellite site so both sites have control over
pan/tilt/zoom equipped cameras located at the
satellite site. The TC8780 Series unit can then be
connected to one of the data outputs of the TC8569-
2 Series unit.
Satellite Site Programming Requirements
The optional TC8850 Graphical User Interface
Software (GUI) package or the TC8x59 Master
Control Software (MCS) package is required to
properly program a satellite system. With the
TC8x59 Master Control Software, it is necessary that
an appropriate version of the program be available
for each type (TC8300 Series, TC8500 Series,
TC8600 Series, and/or TC8800 Series) of Allegiant
system being used in the system.
If a single Master Control Software package is
purchased, its security device and cable can be
used with any of the program disks which are
now supplied with a system’s CPU module to
properly configure a Satellite system.
Programming the satellite sites is usually limited to
designating their ‘logical’ camera numbers to
appropriate values via the Camera ID Table of the
GUI or MCS. If TC8112B Series or TC8124B Series
are being used as satellite switchers, the starting
camera number can be designated using their on-
screen programming menus.
THE STARTING CAMERA NUMBER SHOULD
NOT BE CHANGED IN TC8112B OR TC8124B
SERIES SITES WHERE LOCAL PAN/TILT/ZOOM
EQUIPPED CAMERAS WILL BE USED SINCE THE
TC8135B SERIES CONTROLLER FOLLOWER
CAN ONLY ADDRESS NUMBERS FROM 1 TO 24.
Note that there can be no duplicate camera numbers
anywhere in the system. Allegiant logical camera
designations can be renumbered to any four digit
number on TC8300, TC8600 Series or TC8800
Series systems, and any three digits on TC8500
systems. Only two digit camera numbers can be
selected with TC8112B or TC8124B Series
switchers. There are few other restrictions. These
camera numbers will be the numbers entered at both
the satellite and the main site keyboards when
camera selections are made. On any pan/tilt/zoom
equipped camera, this logical number must also be
entered as the receiver/driver’s site address number.
To maintain a sense of order, it is generally
preferable if a satellite is programmed for a range of
camera numbers. For example, in a three Allegiant
type satellite system, the first satellite can be
programmed for camera numbers 1 to 50. Satellite
two can be programmed for camera numbers 101 to
131, and satellite three can use numbers 201 to 225.
If necessary, the GUI or MCS software’s Keyboard-
to-Monitor Lockout Table can be programmed in the
satellite switcher to prevent any local operators from
inadvertently accessing the satellite’s monitor
outputs being used as Trunk lines. Once
TC8112B/TC8124B Series switchers are configured
for satellite operation (via their on-screen menu
