Since Allegiant Series switchers can act as Main site
switchers, they provide additional logical camera
numbers for identifying the location of the satellite
camera inputs in the system. These logical camera
numbers can also be used to provide titles which
would appear on the Main site’s monitors for any
remote cameras. Since each camera (anywhere in the
system) must have a unique camera number, logical
camera numbers together with physical camera inputs
make up the total system camera capacity. Thus, there
is a trade-off between the total number of Main site
cameras and the number of inputs used as trunk lines.
The more inputs used as trunk lines, the fewer there
are for use as direct camera inputs.
*Camera inputs at all sites, plus trunk lines.
The Main site system must be programmed via
the Master Control Software for Windows
LTC 8059/00 or the LTC 8850/00 GUI, to identify
camera trunk line inputs as well as remote satellite
cameras. All systems must be configured with no
duplicate camera numbers anywhere in the system.
Any alarm inputs to the Main site configured to
activate satellite cameras operate normally except
when limited by the number of available trunk lines.
The software automatically determines trunk usage,
depending on the priority level of operators currently
viewing satellite cameras. 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, the Main
site’s LTC 8540/00 Alarm Interface unit must be
remotely located. Multiple LTC 8540/00 Alarm
Interfaces may be remoted via the LTC 8713 Alarm
Port expander accessory, located at the Main switcher
site in LTC 8800 and LTC 8900 systems. Up to 2
LTC 8540/00 Alarm Interfaces with a LTC 8713 Alarm
Port Expander can be used in a LTC 8600 system.
One LTC 8540/00 can be used in LTC 8500 systems.
Since the LTC 8100, LTC 8200, and LTC 8300 Series
contain an integral alarm interface, the remote alarm
interface application does not apply.
A unique time and date synchronizing feature
provided in the Time Event table of the MCS for
Windows or the GUI software 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.
