4DESCRIPTION
The LTC 8555 Series Keyboard is the primary
operator interface to the Allegiant Series of Video
Matrix Switcher/Controllers. These keyboards provide
access to system switching operations, programming,
alarm response, and camera control. Both fixed speed
and variable speed pan/tilt-equipped cameras are easily
operated via the intuitive joystick control. In addition,
simple rotation of the joystick knob allows operators to
control cameras equipped with motorized zoom lenses.
Easy to read LED displays show real time camera,
monitor, and communication status, as well as error
messages. Keyboards also provide audible and visual
indications of system alarm conditions. A built-in
diagnostic mode makes troubleshooting of suspected
fault conditions easy.

In LTC 8600, and LTC 8900 systems, standard
keyboards above eight are connected to the systems
using either an LTC 8714 Series Keyboard Port
Expander, or a combination of LTC 8714 and
LTC 8715 Series Keyboard Port Expander accessory
units. Keyboard Port Expander units are Allegiant
accessory devices that are purchased separately. In
LTC 8800 systems, keyboards above eight can be
connected to the LTC 8802 Monitor Expansion bay
(up to 8 more) and/or Keyboard Port Expanders.
RS-232 model keyboards are connected to the
Allegiant’s console or printer port or to ports provided
by a LTC 8712 Series Console Expander unit.
When connected directly to an Allegiant CPU bay
using either the supplied cable or the optional
LTC 8558 Extension Cable, the keyboard is powered
by the Allegiant power supply. In all other
configurations power to the keyboard is typically
provided via a power adapter included in the optional
LTC 8557 Series Remote Hookup kit.
