7.10 LTC 8569, LTC 8570, LTC 8571, LTC 8572 Series Code Merger
Units
These series are control code merger and line driver units used to combine Allegiant
biphase control code from two (up to four with LTC 8570 and LTC 8572 versions)
systems for communicating to AutoDome Series cameras, receiver/drivers,
switcher/followers, and Allegiant Satellite systems. The LTC 8569, LTC 8570 Series
provides 32 separate outputs capable of driving up to 256 remote devices. The
LTC 8571, LTC 8572 Series provides 64 separate outputs capable of driving up to
512 remote devices. Either “star” or “daisy chain” wiring configurations may be
used. The unit will accept signal input either from an Allegiant main CPU bay,
LTC 8568/00 output, LTC 8780 biphase output, or an output from another
LTC 8569, LTC 8570 Series or LTC 8571, LTC 8572 Series unit. Multiple units may be
cascaded to obtain additional outputs.
7.11 LTC 8770 Switcher Follower Series
The LTC 8770 Series is an accessory unit which provides relay contact closures cor-
responding to cameras displayed on system monitors. The LTC 8770 may be config-
ured to follow manual activations, non-alarmed video, alarmed video, or both. Each
unit provides 24 relay contact outputs. In addition, six (6) functional operating
modes are available, including one user activated test mode.
7.12 LTC 8712 Series Console Port Expander Units
The LTC 8712 Series “expands” an Allegiant system's console port to permit up to
four external computing devices to communicate with the system via RS-232 proto-
col. Any computing device that can normally communicate directly with an Allegiant
via its RS-232 console port can be used with these port expanders. The external
devices may consist of PCs running the Allegiant system's MCS package, the Alle-
giant GUI, access control systems, Allegiant RS-232 protocol keyboards, or other
devices utilizing the Allegiant system's Command Console Language (CCL).
7.13 LTC 8713 Alarm Port Expander Units
The LTC 8713 Series interfaces to the alarm port of an Allegiant system to permit
additional LTC 8540/00 Alarm Interface units to be connected. In a LTC 8500 sys-
tem, two (2) LTC 8540/00 units can be connected to a LTC 8713 Series unit provid-
ing up to 128 alarm inputs. In LTC 8600 systems, up to eight (8) LTC 8540 Series
units can be connected to three (3) LTC 8713 Series unit providing up to 512 alarm
inputs. In LTC 8800 systems, up to sixteen LTC 8540 Series units can be connected
to five (5) LTC 8713 Series unit providing up to 1024 alarm inputs.
7.14 LTC 8714, LTC 8715 Series Keyboard Port Expander Units
The LTC 8714 Series and the LTC 8715 Series are port expander accessory units
used to provide additional keyboard capacity for LTC 8600 and LTC 8800 Series Alle-
giant systems. A single LTC 8714 Series unit can be used to interface up to eight (8)
additional keyboards in an LTC 8600 series Allegiant system. In LTC 8800 systems,
up to three (3) LTC 8714 Series units can be connected to a single LTC 8715 Series
to provide a quantity of 24 “port expanded” keyboards for a total of 32 system key-
boards. Alternatively, all 32 system keyboards can be connected using four(4) LTC
8714 Series units and a single LTC 8715 Series unit.
