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.

The above table assumes eight system keyboards are
connected directly into the Allegiant CPU bay 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
2
(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.
