3DESCRIPTION
This publication provides instructions for installing the
LTC 8714 Series and LTC 8715 Series Keyboard Port
Expanders in an Allegiant
®
Series matrix
switcher/controller system.
A single LTC 8714 Series unit can be used to interface
up to eight Allegiant Series keyboards with an
Allegiant system. A single LTC 8715 Series unit is used
to interface up to four (4) 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 table
below lists the various Allegiant models and the
maximum number of keyboard expander units and
Allegiant Series keyboards that can be connected in a
system.

NOTE: The above table assumes 8 system keyboards
are connected directly into the Allegiant CPU bay
keyboard ports.
For each Allegiant Series keyboard used in an
"expanded configuration," one LTC 8557 Series
Keyboard Extension Kit (not included) is required.
Each keyboard port expander is supplied with a single
interface cable. This cable is used to connect the port
expander to either the Allegiant CPU bay or to
another port expander. The LTC 8557 Series Kit is
then used to connect the expanded keyboards to the
LTC 8714 Series Port Expander(s). See Typical
Application Diagrams found at the end of this manual.
WARNING: Electrostatic-sensitive
device. Use proper CMOS/
MOSFET handling precautions to
avoid electrostatic discharge.
