The Main site system must be programmed via the MCS 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 any-

where in the system. The installer should verify that the camera numbers pro-

grammed into the Start-up 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 dis-

played 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 14, “User Information,” on page 38) 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 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.

A conceptual diagram of a satellite switching system is follows:

1 2 ... 86 87 88 89 90 91 92 93 94 95 96 ... 103 104
