Philips Allegiant LTC 8500 Series Instructions For Use Manual page 79

the 'logical' camera numbers together with the
'physical' camera inputs make up the total system
'camera' capacity. In practice, there is also a trade
off between the total number of Main site cameras
and the number of inputs which are used as Trunk
lines. The more inputs used as Trunk lines, the less
there are available for use as direct camera inputs.
In any case, the maximum number of system
cameras (camera inputs at all sites plus Trunk lines)
for the TC8300 is 160. The maximum number for the
TC8500 is 320. The maximum number for the
TC8600 is 1152. The maximum for TC8700 and
TC8800 systems is 2304. The maximum number for
the LTC 8900 is 4608.
The Main site system must be programmed using the
optional TC8x59 Master Control Software package or
the TC8850 Graphical User Interface software
package to identify camera trunk line inputs as well
as remote satellite cameras. All systems must be
configured so that there are no duplicate camera
numbers anywhere in the system. Allegiant systems
must be configured with either the optional TC8x59
Master Control Software package or the optional
TC8850 Graphical User Interface software package;
see the appropriate
configuring TC8112B and TC8124B switchers.
NOTE: TC8112B AND
SWITCHERS CAN ONLY
CAMERA NUMBERS. THESE SWITCHERS CAN
NOT BE USED IN SITES WHERE THE CAMERA
NUMBERS WOULD EXCEED 99. THE STARTING
CAMERA NUMBER SHOULD NOT BE CHANGED

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 Main site's TC8540C Alarm Interface unit must
be remotely located. Up to 16 TC8540C Alarm
Interfaces may be remoted using a TC8713A Alarm
Port expander accessory unit located at the Main
switcher site in TC8800 and LTC 8900 systems. Up
to 8 TC8540C Alarm Interfaces with a TC8713A
Alarm Port expander can be used in a TC8600
system. Two TC8540C can be used in TC8500
systems. Since the TC8300 contains an integral
alarm interface,
application would not apply with this model.
A unique time and date synchronizing feature
provided in the Time Event table of the Master
Control Software package may be programmed into
the main site switcher. This permits periodic
synchronizing of the time and date to all switchers in
the system based on the main site's clock.
A conceptual diagram of a satellite switching system
is included in this manual for your reference.
