LTC 8590 Series

Allegiant

Coaxial Transmission Systems

(ACTS)

ACTS mixes and matches audio, video, data, and camera

control and interfaces with other equipment like door

strikes, request-to-exit switches and door contacts. Refer

to the LTC 8590 Series data sheet for complete

specifications.

LTC 8714 Series and LTC 8715 Series

Keyboard Port Expanders

The LTC 8714 Series and the LTC 8715 Series are port

expander accessory units used to provide additional

keyboard capacity for LTC 8600, LTC 8800, or LTC 8900

Series Allegiant systems. A single LTC 8714 Series unit can

be used to interface up to eight keyboards with an allegiant

system. A single LTC 8715 Series is used to interface up to

four LTC 8714 Series expanders in a system. Multiple

LTC 8715 Series expanders can be used along with multiple

LTC 8714 Series expanders to provide up to 64 keyboards

in a system.The actual number of units that can be used in a

system depends upon the model of the Allegiant system.

Allegiant System Capacities

Allegiant Maximum No. Maximum No. Maximum No.

Model No. of Keyboards of LTC 8714 of LTC 8715

LTC 8600 16 1 0

LTC 8800 32 3 1

LTC 8900 64 7 3

The above table assumes eight system keyboards are connected directly

into the Allegiant CPU bay keyboard ports.

An LTC 8557 Series keyboard hookup kits are required for

each expanded keyboard.

LTC 8714 and LTC 8715 port expanders can only be used

on LTC 8600, LTC 8800, and LTC 8900 systems containing

CPU software version 6.2 or later.

keyboard hookup kits are required for each Allegiant

series keyboard to be interfaced to LTC 8714 Series.

LTC 8715 Series Connectors:

Interface Data Ports: Five 9-pin connectors provide data

interface to COMM2 port of main Allegiant CPU bay

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

Two meter (6 foot) interconnect cable for main bay

interface supplied.

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

(6 ft) long.

LTC 8780 Series Data Converter Units

The LTC 8780 Series are accessory units that convert the

Allegiant system's biphase control code into RS-232, and

converts RS-232 back to biphase 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 biphase

control code generated by an Allegiant main CPU bay, a

LTC 8568/00 Signal Distribution unit, a LTC 5135 Series

Controller Follower, 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 TC8780 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 data sheet for

complete specifications.

LTC 8781 Series Time/Date Converters

The LTC 8781 Series are accessory units that decode the

Allegiant system's encoded time/date information generated

on the biphase control code line and convert it into an

RS-422 format using the GPS format. This time/date

information can be used to interface into external time/date

inserter products (such as the Kalatel KTS-53-16), which

are designed to be synchronized via a GPS signal. The

electrical and mechanical specifications are the same as the

LTC 8780 Series units.

LTC 8782 Series Code Translator Units

The LTC 8782 Series are code translators which can

convert Allegiant control code to and from other

manufacturer code formats. Contact your local

manufacturer’s representative for additional information.
