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.
