6 | Accessory Packages for the Allegiant

required for each Allegiant LTC 8555 series keyboard to be

interfaced to LTC 8714 Series. For the IntuiKey Series

keyboards, a separate power pack can be used.

LTC 8715 Series Connectors

Interface Data Ports: Five (5), 9-pin, Sub D connectors

provide data interface to COM 2 port of main Allegiant CPU

bay and data interface for up to four LTC 8714 Series units.

Two-meter (6-ft) interconnect cable for main bay interface

supplied.

AC Input: 3-wire power cord with grounded plug; 1.8 m

(6 ft) long.

Weight 1.9 kg (4.3 lb)

Optional Rack Mount Kit LTC 9101/00 (Holds 1 or 2 units)

LTC 8780 Series Data Converter Units

The LTC 8780 Series are accessory units that convert the

Allegiant system's Bi-Phase control code into RS-232, or

converts RS-232 back to Bi-Phase code. This provides the

capability of transmitting the control code over

conventional RS-232 transmission mediums such as phone

modems, fiber optics, microwaves, etc. The unit will accept

the Bi-Phase control code generated by an Allegiant main

CPU bay, a LTC 8568/00 Signal Distribution unit, or an

output from a LTC 8569, LTC 8570 Series or LTC 8571,

LTC 8572 Series Code Merger unit.

The LTC 8780 Series are also designed to perform the

Satellite selector functions in an Allegiant Satellite system

configuration. In addition, using its integral signal

distribution capability, the LTC 8780 Series can function as

a remote distribution unit providing 15 separate outputs. As

a distribution unit, wiring can be in either a “star” or “daisy

chain” configuration and each output is capable of driving

8 receiver/driver loads at up to 1.5 km (5000 ft) away using

1 mm

(18 AWG) shielded-twisted pair (Belden 8760 or

equivalent).

Refer to separate datasheet for complete specifications.

LTC 8782 Series Code Translator Units

The LTC 8782 Series Code Translators are accessory units

that convert Bi-Phase code to other manufactures’ control

codes, or convert other manufactures’ codes to Bi-Phase.

Many of the most popular protocol codes are supported,

including Pelco, Vicon, American Dynamics, Sensormatic,

Kalatel, Diamond Electronics, and Javelin. Fixed and

variable speed codes are supported where applicable.

The LTC 8782 Series Code Translators have four

independent outputs. Removable screw terminal blocks are

used for input and output connections. The Front panel

LEDs indicate the status of power, data receive, and data

transmit. The translator comes supplied in an EIA 48 cm

(19 in.) rack-mount adapter that can hold up to three units.

Refer to the LTC 8782 series data sheet for complete

specifications.

LTC 8785 Series Code Converters

LTC 8785 Series units are designed for use in very old

Allegiant systems that have been upgraded to support

‘variable speed’ control code protocol. The LTC 8785 units

are used to provide a source of 'fixed speed' control code

when the system is generating the new ‘variable speed’

control code preferred by the AutoDome series of PTZ

cameras. The LTC 8785 receives variable speed control

code from the Allegiant via its LTC 8568/00 Signal

Distribution unit and converts it into appropriate fixed

speed control code. The ‘fixed speed’ control code outputs

from the LTC 8785 Series connect to the older TC8561

Series receiver/drivers using the existing field cabling.

LTC 8786 Data Converter Series

The LTC 8786 Series of data converters are designed to

convert Bosch “Receiver/Driver and AutoDome RS-232

Control Code Protocol” into Allegiant Bi-Phase control

code. These units are the preferred method for

transforming a single RS-232 data output from a DVR (or a

similar device) into multiple control code outputs for
