In addition, this option changes the behavior of how
the system determines which Trunk Line to use.
When this option is not used, a new Trunk Line (if
available) will be used for each camera selection.
When this option is enabled, an operator’s monitor
will use the same Trunk from the same bay as different
cameras are selected, as long as no other operator is
viewing the same Satellite camera. In 3-tier cascaded
Satellite systems, this feature minimizes the use of
Trunk Lines by the top level Master system. This is
especially advantageous when the operator at the
Master site is viewing cameras from the 3rd level
Satellite. Since this will result in less Trunk Lines being
used up, the intermediate Master/Satellite system will
have more access to Trunk Lines from the 3rd level
Satellite.
c) "SAT nnn PRIORITY" option. If the top level
master system and intermediate level system in a
cascade configuration can or will be set to operate as
"Dual Master" systems, a priority based satellite
camera selection feature can be configured. In a
default cascaded satellite system configuration, satellite
switching commands are not associated with a user
priority level. When a switching command sent from a
master site is received by a satellite, the switch
selection can immediately be overridden by operators
at the satellite location having any priority level. This
situation is more likely to be encountered in 3-tier
Satellite systems that do not have a good distribution
of trunk lines (i.e., more between the top level system
and the intermediate level system than there are
between the intermediate system and the 3rd tier
satellite).
Since dual master configurations support bi-directional
communications, selecting the "SAT nnn PRIORITY"
option for both the top level and intermediate level
master systems will result in the generation of priority
based satellite commands.
The Satellite number assigned to the system that is
currently being programmed must be specified for the
"nnn" value. This feature will enable use of the
operator s user priority to determine if access to a
desired satellite camera is provided or not. For
instance, if no Trunk Lines are available and an
operator requesting a satellite camera has higher
priority than at least 1 of the existing operators, the
requested camera will be switched. If the operator does
not have sufficient priority, they will receive an error
message (i.e., error 81) via the satellite communication
path, and their camera will switch to the Start-up
camera specified in the Monitor table.
In addition, the same behavior for selecting Trunk
Lines as described in the "NO REM CAM CACHE"
option is applicable to this option. An operator’s
monitor will use the same Trunk from the same bay as
different cameras are selected, as long as no other
operator is viewing the same Satellite camera.
6.1.43 User Function 42
Keyboard Login Auto-off Mode
Priority 1 users can use this function to select a keyboard
logoff feature to automatically log a keyboard off after a
preselected time of inactivity. After entering the mode,
move the joystick up/down to select the desired time
period. Enter a valid password, and press
ENTER . If using
the LTC 8555 keyboard, press USER to exit the mode.
6.1.44 User Function 43
CPU Battery Status
Use this function to view the condition of the batteries
used to backup CPU memory. Once the function is
entered, the condition is displayed on the monitor text
display. If using the LTC 8555 keyboard, press
USER to
exit the mode.
User Function 44 Camera Vertical Phase Set
NOTE: This feature requires the following:
a) LTC 8621 or LTC 8821 video input modules having
firmware 5.30 or later.
b) Dinion series of cameras using Bilinx communications.
c) AutoDome series of cameras using either Bilinx or
Biphase data communications.
d) LTC 8016/90 Bilinx Data Interface unit having
firmware 1.01 or later.
e) All cameras configured to use Line Lock mode.
Priority 1 users can use this function to automatically
adjust the phase interval delay of compatible cameras
connected to the system. This will result in roll-free
switching as the cameras are manually selected or
automatically sequenced on system monitors.
After entering the function, the joystick down/up is used
to select either an individual camera to adjust or all
cameras. Enter a valid user password number and press
ENTER to activate the adjustment process.
