LTC 8900 Series
1. Camera inputs at all sites, plus trunk lines.
The Main site system must be programmed via the Master Control Software 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.
The installer should verify that the camera numbers programmed into the 'Startup Camera'
field of the Monitor table are suitable for viewing by respective operators. If there are
Lockouts programmed into the system, specifying 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 connected 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 Keyboard User Function section) 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 8 LTC 8540/00 Alarm Interfaces
with LTC 8713 Alarm Port Expanders can be used in a LTC 8600 system. Two LTC 8540/00
can be used in LTC 8500 systems. Since the LTC 8300 Series contains 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 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.
