3 Keyboard Models
The LTC 8555 Series keyboards are available in four models. The table below summarizes the
differences between models:
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 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.

5 Installation
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:
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.
The Allegiant Switcher supports several options affecting keyboard operation:
– login security mode setting
– enabled / disabled keyboard ports
– fixed or variable speed communication protocol setting
– 4-digit or 6-digit Camera ID mode
These options are selected via Allegiant CPU dipswitch settings, Allegiant Keyboard User
Functions, or via options in the PC based Master Control Software package. Refer to the
Allegiant Installation manual for complete details regarding these options.
Several options are available to connect the LTC 8555 Series Keyboards to the Allegiant main
CPU bay. Although other configurations are possible, the tables below summarize typical
connections. Additionally, refer to the system configuration diagrams later in this manual.

5.2 LTC 8555/00 and LTC 8555/01 (standard keyboard) Installation
There are several options available for connecting these keyboard models to an Allegiant
system. The keyboard is supplied with a 3 m (10 ft) cable for local hookups, as shown in
FIGURE 1. Using the optional LTC 8558/00 cable, a keyboard can be remoted up to 30 m (100
ft) per Figure 2. In both of these cases, the keyboard cable can be connected directly to the
RJ-11 keyboard port located on the rear panel of the Allegiant system where it will be
provided with both data and power.
For connections beyond 30 m (100 ft), the LTC 8557 Series Remote Hookup Kit can be used,
as shown in Figure 3. The LTC 8557 is also required when the keyboard is remoted over a long
distance communication link, such as a fiber optic system shown in Figure 4.

Installation
5.3.1 General
The RS-232 protocol versions of the LTC 8555 Series keyboards can be connected to either an
Allegiant LTC 8712 Series Console Port Expander accessory unit, or the 9-pin Console or
Printer (if equipped) RS-232 port on the back of the Allegiant system. The keyboard may be
connected via hardwired cable or using another type of communication system conforming to
standard RS-232 transmission.
For each keyboard being installed, an LTC 8557 Series Remote Hookup Kit (sold separately),
user-supplied 9-pin mating connector, and user-supplied cable suitable for use with RS-232
signals is required. Refer to the most applicable configuration diagram.
5.3.2 Keyboard Number Assignments when Using RS-232 Model Keyboards
Use of RS-232 protocol keyboards does not increase the total number of keyboards that can
be connected to an Allegiant switcher. When an RS-232 keyboard is connected in the system,
a standard keyboard port will automatically become disabled. The disabled keyboard port
number will be based on the interface connection type of the RS-232 keyboard. Keeping track
of these keyboard numbers is necessary when priority-based restrictions, or other keyboard
related lockouts, are assigned and used in the system.
The table below indicates which keyboard number will be assigned, based on the connection
being used.

5.3.3 Allegiant System Command Scripts for RS-232 Model Keyboards
When a keyboard is being connected to an Allegiant’s Console port, or an Allegiant Printer
port configured to operate in the Console mode, the Allegiant must be preprogrammed so the
port will operate in the RS-232 keyboard mode.
The mode of the Allegiant’s Console port can be changed either by a manually entered ASCII
text command, or preprogramming the Allegiant CPU with an Allegiant Command Script. The
Command Script method is preferred since the appropriate settings are automatically
restored after a system power loss or reset. Manually entered commands remain valid only
until the system is reset or powered off/on, so typically they should be used only for
temporary or test purposes.
To manually configure an Allegiant’s Console port to operate in the keyboard mode, it is
necessary to connect to the system via Windows® HyperTerminal or another dumb terminal
emulator.
Note: Allegiant Console and Printer RS-232 ports do not use a standard RS-232 pinout. Use of
an Allegiant Console cable is recommended (If necessary refer to the Allegiant Console cable
pinout reference at the end of this manual).
The Allegiant RS-232 settings are user-programmable, but the default settings are:
Once online with the system, an Allegiant prompt appears each time Enter is pressed. The
prompt will look as follows:
TC8x00 >
where x is a digit from one to nine (varies based on the Allegiant model being interfaced)
At the system prompt, manually enter the appropriate command, based on the Allegiant port
in use, and type of keyboard interface. Refer to the table below to determine the correct
command. Enter the command exactly as shown below, then press ENTER.

After entering the command, the port will immediately begin to operate in the keyboard mode.
The port will generate a series of constantly repeating codes. The setting remains in effect
until the system is reset, powered off/on, or manually cancelled by entering Ctrl-C several
times, using Windows HyperTerminal program operating at 9600 baud.
