Safety Precautions
For Indoor Product
1. Water and Moisture - Do not use this unit near
water - for example, in a wet basement, in an
unprotected outdoor installation or in any area
classified as a wet location.
CAUTION: TO REDUCE THE RISK OF
2. Object and Liquid Entry - Never push objects of
any kind into this unit through openings, as they
might touch dangerous voltage points or create
short circuits, resulting in a fire or electrical
shock. Never spill liquid of any kind on the unit.
3. Power Cord and Power Cord Protection - For
units intended to operate with 230VAC, 50Hz,
the input and output power cord must comply
with the latest versions of IEC Publication 227 or
IEC Publication 245.
ELECTRIC SHOCK, DO NOT REMOVE COVER
(OR BACK). NO USER SERVICEABLE PARTS
INSIDE. REFER SERVICING TO QUALIFIED
SERVICE PERSONNEL.
This symbol indicates the presence of
uninsulated “dangerous voltage” within the
product’s enclosure that can cause an electric
shock.
This symbol indicates the presence of
important operating and maintenance
(servicing) instructions in the literature
accompanying the appliance.
Power supply cords should be routed so they are
not likely to be walked on or pinched. Pay
particular attention to location of cords and plugs,
convenience receptacles, and the point of exit
from the appliance.
Installation should be performed by qualified
service personnel only in accordance with the
National Electrical Code or applicable local
codes.
4. Overloading - Do not overload outlets and
extension cords; this can result in a risk of fire or
electrical shock.
Power Disconnect. Units with or without
ON-OFF switches have power supplied to the
unit whenever the power cord is inserted into the
power source; however, the unit is operational
only when the ON-OFF switch is in the ON
position. The power cord is the main power
disconnect for all units.
For Outdoor Product
Power Lines - An outdoor system should not be
located in the vicinity of overhead power lines,
electric lights or power circuits, or where it may
contact such power lines or circuits. When
installing an outdoor system, extreme care should
be taken to keep from touching power lines or
circuits, as this contact might be fatal. U.S.A.
models only - refer to the National Electrical
Code Article 820 regarding installation of CATV
systems.
For Rack-mount Product
1. Ventilation - Do not place this equipment in a
built-in installation or rack, unless proper
ventilation is provided, or the manufacturer's
instructions were followed. The equipment must
not exceed its maximum operating temperature
requirements.
2. Mechanical Loading - When rack-mounting the
equipment, ensure that a hazardous condition is
not created by uneven mechanical loading.

DESCRIPTION
Unpack carefully. This is electronic equipment and
should be handled carefully.
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.
Check for the following items:
•
•
Verify the model number of the unit.
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.
One (1) cable assembly with 9-pin D-sub
connectors.
If an item appears to have been damaged in shipment,
replace it properly in its carton and notify the shipper.
If any items are missing, notify your Bosch Security
Systems, Inc. Sales Representative or Customer
Service.
The shipping carton is the safest container in which the
unit may be transported. Save it for possible future use.

INSTALLATION
The LTC 8714 Series Keyboard Port Expanders and
the LTC 8715 Expander communicate with the
Allegiant Series main bay and the Allegiant Series
keyboards via RS-485 communications. The LTC 8714
Series Keyboard Port Expanders and the LTC 8715
Series Expander contain internal DIP switches which
can be used to set the communication parameters.
The cover must be removed if the DIP switches need
to be changed from their factory default settings. See
FIGURE 1. The following table summarizes the DIP
switch settings and their associated features. Note that
after changing any of the DIP switch settings, the AC
power must be turned off and on before the changes
can take effect.

6. Similarly, repeat Step 5 for each Allegiant Series
keyboard.
4.5 Connections
4.5.1 Expanding up to Eight Keyboards Using the
LTC 8714 Series Keyboard Port Expander
1. Make sure power is turned OFF on the
Allegiant Series main bay and the LTC 8714
Series Keyboard Port Expander. Make sure that
the external power supply used to power the
Allegiant Series keyboards is not connected to
a wall outlet.
7. Using the cable supplied with the LTC 8714
Series Keyboard Port Expander, connect one
end of the cable to the connector marked
SYSTEM on the LTC 8714 Series unit. Connect
the other end of the cable to the connector
marked COMM2 on the Allegiant Series system
(see FIGURE 9).
4.5.2 Expanding Beyond Eight Keyboards Using
the LTC 8714 Series Keyboard Port Expanders
with the LTC 8715 Series Expander
In order to expand beyond eight keyboards, the use
of an LTC 8715 Series unit in conjunction with an
LTC 8714 Series unit is required. Using multiple
LTC 8715 units, the remote keyboards can be
expanded to 120. Note that the maximum number
of keyboards may be limited by the Allegiant system.
See FIGURE 10.
2. For each keyboard used with the LTC 8714
Series, one LTC 8557 kit is required. The
LTC 8557 kit consists of two junction boxes,
a power supply, a barrel plug cord, and a
3 meter (10 ft) keyboard cable.
3. Connect the 3m (10ft) cable supplied with the
keyboard between the keyboard and the remote
junction box.
4. Up to 1.5km (5000ft) of customer supplied
0.5mm2 (24AWG) shielded twisted pair (Belden
9841 or equivalent) may be run between the
two junction boxes. Connection to the junction
boxes are made to three of the four screw
terminals as follows. Note reversal to data
connections.
1. Follow Steps 1 through 7 in the previous section
for connecting up to eight keyboards using the
LTC 8714 Series unit.
2. Select the appropriate group number on the
LTC 8714 Series unit via dip switch S402,
switches 2 through 5. The group number must
be unique and must not conflict with other
LTC 8714 units or the local keyboards (i.e.,
keyboards connected directly to the ports
located on the main CPU bay) in the Allegiant
system.

3. Using the cables supplied with the LTC 8714,
connect the SYSTEM port on the LTC 8714 to
any one of the four PORTS on the LTC 8715
unit. Repeat steps 1 and 2 for all LTC 8714
Series units.

5. Connect the 3m (10ft) cable supplied
with the LTC 8557 kit between the junction
box and the PORT connector on the LTC 8714
Keyboard port expander. Connect the power
supply to the junction box at the remote
keyboard site. Verify that the junction box
power LED indicator lights. Also verify that the
keyboard LEDs are flashing.
4. Using the cable supplied with the LTC 8715 unit,
connect the SYSTEM port on the LTC 8715
Series unit to the COMM2 port on the Allegiant
Series main bay. In this configuration, up to
32 remote keyboards can be connected using
four LTC 8714 units and one LTC 8715 unit. To
expand beyond 32 remote keyboards, another
tier of LTC 8715 units may be used (see
FIGURE 11).

OPERATION
1. Turn on the Allegiant Series main bay, the
LTC 8714 Series Keyboard Port Expander,
and the LTC 8715 Series Expander. The
power LEDs on the LTC 8714 Series unit
and the LTC 8715 Series unit should be on.
2. Note that the system Tx LED on the front panel
of the LTC 8714 Series Keyboard Port Expander
will flash whenever data is being sent to the
Allegiant system (or to an LTC 8715 Series
Expander) from the LTC 8714 Series Keyboard
Port Expander. The system Rx LED will flash
whenever data is being received from the
Allegiant system (or from an LTC 8715 Series
Expander). Data is also occasionally sent from
the Allegiant system to reflect applicable system
changes and on an occasional basis to maintain
current system status.
The port LEDs on the LTC 8714 Series
Keyboard Port Expander will indicate active
data communication to a connected keyboard.
LEDs on the front panel of an LTC 8715 Series
Expander will indicate communication between
the Allegiant system and the associated
LTC 8714 Series Keyboard Port Expanders
that are connected to it.
