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.

keyboard ports. An LTC 8557 Series keyboard hookup

kit is 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.

LTC 8714 Series Connectors

Interface Data Port: One (1), 9-pin Sub D connector

provides data interface to COM 2 port of main

Allegiant CPU bay or to expansion port of LTC 8715

Series. Two-meter (6-ft) interconnect cable supplied.

Keyboard Data Ports: Eight (8), 6-contact non-

powered Allegiant series keyboard cable connectors.

An LTC 8557 Series keyboard hookup kits are 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.

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.
