used to provide variable speed pan/tilt control capability for

AutoDome equipped camera sites and is only compatible with

LTC 8550/00, LTC 8551/00, LTC 8552/00, LTC 8553/00,

LTC 8554/00, and LTC 8555/00 type keyboards. Note that the

variable speed mode is not compatible with the older LTC 8561

receiver/drivers without the use of a LTC 8785 Series Code

Converter unit.

If necessary, dip switch 7 can be turned off (usually at time of

system installation) to allow operation with the older 'fixed speed

only' type keyboards which use a '4 poll byte' protocol. In this

mode, the system can communicate with the older LTC 8561

series of receiver/drivers without the use of the LTC 8785 Code

Converter unit. Please note that the 'fixed speed' keyboard mode

allows only the first 63 auxiliary and pre-position functions to be

accessed. This is not a issue on older receiver/driver versions, but

it may pose a problem if the system will be expected to access all

the functions available in the AutoDome series of pan/tilt/zoom

dome cameras.

Switch 8

Switch 8 controls the protocol settings of the Console and Printer

external RS-232 ports.

If the switch is turned OFF, the system will always use the factory

default settings for the RS-232 data communication protocols as

listed below.

With switch 8 ON, any RS-232 port protocols changed using

Keyboard User Function 30 (covered later in this manual), the

optional LTC 8359/00 Master Control Software, or the optional

LTC 8850/00 Graphical User Interface software package are active.

Users with priority level 1 can also use keyboard User Function

29 to reset any changed protocols back to the default settings

(see below).

Switch 8 also controls the activation of a 'boot screen' program

previously downloaded into the CPU's memory. The 'boot

screen' is a custom program provided by the Factory to provide

special system functions or features. If the switch setting is OFF,

any existing boot screen will not be active.

If Dip switch 8 is OFF (or after activation of Keyboard User

Function 29) data communication settings for the Allegiant

systems are listed below.

There are eight levels of user priority in the system. Each of the

32 users in the Allegiant system has a default priority level

assignment. These user levels determine access to various system

functions and provide a means to prioritize user control of

monitors and pan/tilt/zoom equipped camera sites. Generally,

users with higher priority (highest = 1) can regain control over

monitors or pan/tilt/zoom cameras 'locked' by another user.

The 8 priority level user assignments can be changed using the

19,200

optional LTC 8059/00 Master Control Software for Windows or

the LTC 8850/00 Graphical User Interface software package, but

for a base system the table above shows the default values that

None

have been set. Note that in base systems where the log-in feature

has not been selected, user number is automatically assigned to a

specific keyboard port. This essentially sets the keyboard as the

priority determinator. Also shown in the table are the default user

passwords assigned to each user as the system is shipped from the

Factory. Once a user is logged-on to the system, the password can

be changed using keyboard User Function number 10. Refer to

the specific section of the operation instructions for exact

procedures of using keyboard User Functions.
