16 Keyboard Operation
16.1 General
Primary operation of an Allegiant switcher is controlled via the system keyboard.
The two types of keyboards currently available are:
•Conventional LTC 8555 Series (incorporates LEDs and pushbuttons).
•IntuiKey model (uses dynamic LCD menu screens).
General operation steps for both keyboard models follows. Refer to the individual
instruction manuals supplied with the keyboard for additional information.
As the system is supplied from the factory, various user selectable features are set to
a default state. See Chapter 13, “Factory Default Settings,” on page 33 for complete
feature descriptions. Since these features are user selectable and can have a signifi-
cant effect on the operation of the system, it is important to take note of any changes
that may be in effect.
16.2 System Commands
Keyboard Log-in Procedure
Keyboard modes:
•Factory default, a keyboard is ready for use as soon as power is applied to the
system.
•System operator must log-on to a keyboard to access the system. When a system
is configured to use the keyboard log-on, operators must be pre-assigned a user
number and password. Up to 32 user numbers are available, each having
default priority level. User specific priority levels can be changed only via the
optional PC-based LTC 8059/00 MCS package or the LTC 8850/00 GUI Soft-
ware. Refer to the software manual for complete details.
If the log-on feature is enabled and an operator is not logged-in, LED keyboards
show flashing dashes in their display. IntuiKey keyboards prompt for entry of a user
number when attempting to enter the main Allegiant softscreen menu.
Enter your assigned user number via the numeric keypad and press [Enter]. When
prompted, enter the password. Invalid passwords cause the keyboard to revert to its
initial state. Once the log-in is successful, the keyboard will show camera and moni-
tor numbers in its display.
Upon logging in, the monitor controlled by the keyboard may automatically switch
to a pre-assigned camera number. This function is only applicable if enabled by the
system administrator (via the optional MCS package) and may not function if the
monitor is running a sequence and/or in an alarm condition.
NOTE The information below applies to both IntuiKey keyboards and the LTC 8555
Series keyboards. Where applicable, button designations specific to IntuiKey
keyboards are shown in plain text. Equivalent button designations that apply to
the LTC 8555 Series keyboards are placed in brackets ([ ]) immediately after
the IntuiKey button text.
