9.2 Local Keyboard Test --
Keyboard User Function 1
Keyboard User Function 1 is an Allegiant system
keyboard feature used to verify that all the keyboard’s
LEDs and switches are in working order. This function
also automatically calibrates the center position of the
analog joystick. Upon starting this test, the keyboard
emits a short beep and all LEDs light for about two
seconds. During this time, note any LED failures.
Each key may be pressed to display a unique code
number associated with that key. Follow the table below
to ensure that the keyboard is properly processing all
keys. The amount of deflection of the Joystick during
pan/tilt actions is indicated by a speed indicator value in
the first digit position of the LED display. Rotation of the
Zoom control indicates a value of x41 when rotated
clockwise, and x40 when rotated counterclockwise. Push
USER last, as this exits the keyboard test mode.
If the login system features have been selected by the
system installer, the same local test can be initiated while
the keyboard is not online, by pressing "*" (the star key).

9.1 General
LTC 8555 Series | Instruction Manual | Troubleshooting EN |28
Bosch Security Systems | 29 August 2003
PROBLEM
No Power Indication
LED Displaying flashing dashes
Non-operating Key or LED digit
Camera and Monitor numbers being displayed, but
Allegiant system will not respond to changes or
P/T/Z controls
Intermittent beeping and/or display of error message
90, 92, 94, or 95.
Possible Causes
a) If powered from a non-modular type Allegiant, try another
keyboard port on the Allegiant. The port may have failed.
b) If powered from a modular type Allegiant, check the fuse on
main Allegiant power supply. Try another keyboard port.
c) If powered from a separate power source, check power
source or main AC supply of power source.
d) If power source is confirmed to be OK, the keyboard may
have an internal failure. Swap suspect keyboard with a
known good keyboard.
a) If the login feature is enabled, the keyboard may be logged
off. (User LED lit and OFF LED lit)
b) If the login feature is not enabled, or the keyboard port is
logged in, there is likely a data communication error. Test the
keyboard cable in another keyboard port. Swap the suspect
keyboard with a known good keyboard. Try another
keyboard data cable. Check keyboard data cable
connections.
c) If using RS-232 protocol models with a dial-up modem link,
the keyboard may be waiting for the operator to dial a phone
number and establish communication with the Allegiant.
a) If a key does not seem to be working, verify that the
attempted function is applicable to the device being
controlled, or the switcher’s current situation.
b) Key or LED may be defective. Run the User Function 1 test
described in section below.
a) Verify that the attempted function is applicable to the device
being controlled, or the switcher’s current situation.
b) If using a directly connected cable, the keyboard port or
keyboard could be defective. Swap the suspect keyboard
with a known good keyboard.
c) If using a communication link other than a directly
connected cable, there could be a problem with the
communication link. Data is being received from the
Allegiant if camera and monitor numbers are displayed, but
these symptoms indicate that the keyboard’s data is not
getting back to the Allegiant. Test with a directly connected
Allegiant keyboard cable. Verify that the communication link
is compatible with Allegiant keyboard data communications.
a) Error 90, Error 92, and Error 94 indicate the Allegiant
system has received invalid data. The most likely cause is
excessive EMI interference on the keyboard data cable,
within the keyboard itself, or possibly in the Allegiant
system. If the keyboard is remoted a long distance, try using
the 3 m (10 ft) data cable supplied with the keyboard.
b) Error 95 indicates that there is intermittent keyboard
communication. Verify the physical data cable connections
and the integrity of the cable connectors.

7.5.17 Programming a SalvoSwitching Camera
Sequence
A SalvoSwitching® sequence allows specification of a
group of monitors that will switch together as a
synchronized group. To program a salvo sequence, enter
the programming mode as described above for a simple
camera sequence. Since a salvo sequence involves
multiple monitors switching as a group, the sequence
must involve more than 1 monitor. An example of a
simple salvo sequence that switches cameras on three
monitors simultaneously is shown below in spreadsheet
format:
In general, follow the instructions used for the simple
camera sequence described above, but instead of
entering a number of seconds for steps that must switch
instantly, enter 61 and press ENTER. When 61 is
entered, the switcher automatically changes to the salvo
abbreviation SLV. Dwell time (in seconds) is entered
only upon reaching the step containing the last monitor
to be switched within the synchronized group.
7. 6Keyboard User Functions
Keyboard User Functions are used to configure system
settings that do not require changing on a frequent basis.
Only operators with a level 1 priority have access to all
functions, and several require entry of a password. A

LTC 8555 Series | Instruction Manual | User Information EN |24
Bosch Security Systems | 29 August 2003
Consider a sequence as being similar to a spreadsheet; a
simple sequence would consist of 3 columns of
information that would look as follows:
Programming of sequences can best be described by
going through the above example. Initiate the
programming mode by pressing PROGRAM. Enter an
available sequence number (1 to 60 for most Allegiant
models; 1 to 256 for LTC 8900 systems), then press
ENTER. The on-screen monitor display will change to
the following format:
1st Line = Camera (Ignore) S0001 L0001 Time (Ignore)
2nd Line = >C0001< M001 D02 Date (Ignore)
The top line of the display always indicates the current
step being viewed, in the S0001 section. Total length of
the sequence is displayed in the L0001 section.
When programming a new sequence, the camera
number that was being viewed before entering the
programming mode is automatically placed within the >
< prompts (as in the above example showing camera
number C0001 on the 2nd line). Enter the first camera of
the sequence into this position. If the camera number is
correct, no action is necessary. If not, enter the desired
camera number via the keypad, and press ENTER.
Using the joystick control, move to the RIGHT one step.
The prompts will shift over to the monitor number
shown above as M001. The monitor that was being
controlled by the keyboard before entering the
programming mode defaults to this position. If it is
correct, no action is necessary. If not, enter the desired
monitor number via the keypad, and press ENTER.
Move RIGHT again. The prompts now shift over to the
dwell time shown above as D02. The default dwell time
for a new sequence is two seconds. If a different dwell
period for this step is desired, change the value to any
number between 1 and 60. One line is now complete.
Press NEXT to add a second line. The camera number
automatically increments, but monitor number and dwell
remain the same as the first line. Since this line is
correct, no change is necessary and NEXT may be
pressed three more times, until line five is reached. Note
that the joystick can be used to move around within the
spreadsheet, but only the NEXT key adds new lines.
Continue entering camera, monitor, and dwell times in
the same fashion until finished.
To store the sequence for future use and then exit
programming mode, press PROG. If you press RUN,
the programming mode exits, the sequence is stored into
memory, and the sequence begins to run. The switcher
steps through the five steps in the order shown, and
repeats the sequence when it reaches the last step.
To program a sequence that runs once through its steps
and then stops, enter the value 62 for the dwell time in
the last step, and press ENTER. The dwell display will
change to the STP indicator, meaning stop. To program
a sequence that runs once through its steps, and then
unloads itself, enter the value 63 for the dwell time in the
last step and press ENTER. The dwell display changes
to ULD, meaning unload.
To edit an existing sequence, press PROG, enter the
existing sequence number, and then press ENTER. You
can insert a line into a sequence by navigating to the
appropriate line and pressing ON. An identical line will
be added to the next step. To delete a step, navigate to
the line and press OFF. To delete all steps below the line
you’re viewing, press LOCK. (Be careful with this
feature!)
To completely erase a sequence, press LOCK while on
the first line of the sequence, and then press OFF. The
sequence is then erased, and programming mode
automatically exits.

3KEYBOARD MODELS
The LTC 8555 Series keyboards are available in four
models. The table below summarizes the differences
between models:
Model No. Top bezel graphics Protocol
LTC 8555/00 English text RS-485
LTC 8555/01 Icons RS-485
LTC 8555/02 English text RS-232
LTC 8555/03 Icons RS-232
The LTC 8555/00 and LTC 8555/01 models use the
Allegiant RS-485 communication protocol, and are the
most common versions. These models are ready to
operate as soon as they’re connected to the Allegiant
system.
The LTC 8555/02 and LTC 8555/03 are similar, but
use an RS-232 communication protocol. These models
can be used with communication links such as dial-up
modems, or other media that support full duplex RS-
232 transmission. Since the RS-232 models connect to
the Allegiant’s RS-232 ports rather than the standard
RS-485 keyboard ports, some initial configuration
programming of the Allegiant switcher is necessary.
With a few minor exceptions, general operation is
identical for all models.
Although the LTC 8555/00 and LTC 8555/01 are
compatible with Allegiant systems of any age, the
LTC 8555/02 and LTC 8555/03 models require
Allegiant CPU firmware version 7.6 or higher.
Although this version was released in late 1998, it is
possible to update older systems using a firmware
download in some cases or by replacement of the CPU
module with a current version. If necessary, contact
your local sales office for additional details.

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.
5INSTALLATION
5.1 General
The maximum number of keyboards that can be
connected to an Allegiant system depends on the
Allegiant model. The following table lists Allegiant
Switcher models and the number of keyboards
supported by each:
Maximum Keyboards
Allegiant Total RS-232 Model
Model Keyboards Keyboards
LTC 8100 Series 2 2
LTC 8200 Series 4 4
LTC 8300 Series 4 4
LTC 8500 Series 8 8
LTC 8600 Series 16 8
LTC 8800 Series 32 8
LTC 8900 Series 64 4/8
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.

Bosch Security Systems | 29 August 2003
7.5.12 Load/Clear a Sequence
To load a previously programmed sequence so it can be
run on your monitor, press SEQUENCE, enter the
desired sequence number (1 to 60 for most Allegiant
models, or 1 to 256 for the LTC 8900 system), and then
press ENTER. Note that loading a sequence does not
automatically initiate the sequence. Refer to the following
sections for sequence control information.
Since sequences may be programmed to use more than
one monitor, all monitors required for a sequence must
be available. If a sequence is already on a monitor, the
operator who loaded it originally (or an operator with a
higher priority) is permitted to load a new sequence on
the monitor or monitors. Others receive an error
message.
To clear a sequence from a monitor, press SEQUENCE
and ENTER. Only the operator who loaded it originally
(or an operator with a higher priority) is permitted to
clear a sequence from a monitor. Others receive an error
message.
If enabled, the status display area of the monitor
indicates the sequence number in the appropriate
location. If no sequence is currently loaded, "00" is
displayed.
7.5.13 Run a Sequence
To run a sequence currently loaded on a monitor, press
RUN. If the sequence was stopped, the RUN command
will initiate sequencing. The direction of sequencing is
indicated in the monitor status display (if enabled) by a
directional arrow and the letter 'R' to the right of the
sequence number. If RUN is pressed while a sequence is
already running, the switcher goes immediately to the
next step in the sequence, and continues to run. Holding
down RUN produces a 'quick-scan' effect. If RUN is
pressed when no sequence is loaded, an error results. If
the monitor is in alarm, RUN controls the switching of
alarm video rather than a loaded sequence.
7.5.14 Stop a Running Sequence
Press HOLD to stop a sequence if one is currently
running. The monitor status display shows 'S' to the right
of the sequence number. If the sequence is already
stopped, pressing HOLD has no effect. If no sequence is
currently loaded, pressing HOLD results in an error
condition. If the monitor is in alarm, HOLD stops the
alarm switcher rather than a loaded sequence.
7.5.15 Controlling the Direction of a Sequence
The direction of a sequence can be set to run in either a
forward or reverse direction. It is also possible to
manually step though a stopped sequence, either forward
or reverse. These actions work as follows:
If NEXT is pressed with the sequence in the stop
state, the sequence switches forward and remains
stopped. If the sequence is running when NEXT is
pressed, it immediately goes to the next step and
continues to run. The same is true for PREV, but in
the reverse direction. If either NEXT or PREV is
held down, a 'quick-scan' effect, switching at a rate of
approximately two steps per second, takes place.
When sequences are first loaded, the direction
defaults to forward.
If PREV is pressed while a camera sequence is
running, it reverses the sequence. If PREV is pressed
while in a hold mode and the display is showing the
forward prompt, the first push changes the direction
only, and a second push switches to the previous
step. The same is true for NEXT in the opposite
direction. The monitor status display shows an arrow
pointing either up or down, indicating the direction
of the sequence. The arrow is to the right of the
sequence number, either above or below the
sequence run ‘R’ or stopped ‘S’ indicator. If the
monitor is in alarm, PREV and NEXT control the
alarm switcher rather than the loaded sequence.
If no sequence is loaded, pressing NEXT or PREV
automatically steps the switcher through the camera
numbers in numerical order.
7.5.16 Programming a Simple Camera Sequence
The Allegiant system has very powerful sequencing
capabilities. Using a system keyboard, it is possible to
enter sequences that will run on a single monitor or
multiple monitors. As long as valid camera and monitor
numbers are used, they can be entered into a sequence
in a completely random order. More powerful features
are available when sequences are programmed via the
PC-based LTC 8059 Master Control Software, including
the capability to activate receiver/driver actions as part
of a sequence step.
The only limitation associated with sequence
programming is the CPU memory required for storing
the sequence steps. The current limit for most Allegiant
models is 3000 steps, but the LTC 8900 supports up to
6000 steps.
