ing a neutral camera would prevent the situation where a restricted camera could
be switched to a restricted operator's monitor when their trunk line is stolen. For
this feature to operate properly, the start-up camera numbers must be locally con-
nected cameras or a local unused input (i.e., the raster generator will be displayed
when called-up).
In addition, it is recommended to program Lockouts for all system keyboards so that
they do not have access to unused monitor outputs. This prevents operators from
inadvertently selecting a satellite camera on a non-existent monitor which will result
in a trunk link becoming used up, possibly making less trunk lines available for valid
selections.
Keyboard User Function 41 (See Chapter 15, "User Information," on page 56) offers
additional programming options if a multi-level cascaded Allegiant satellite system
configuration is being used.
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 two (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 inte-
gral 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 or the GUI Software may be programmed into the Main site switcher. This
permits periodic synchronizing of the time and date to all remote switchers in the
system based on the Main site's clock.
