User Function 38 - Printer Port Mode
This function allows configuration of the system's PRINTER port for use with a LTC
8712 Series Console Port Expander accessory device. Move the joystick up or down
to select the printer port function; NORMAL or EXPANDED. Press [Enter] to activate
your selection. Reset the system for this setting to take effect.
User Function 39 - Select DIU Interface Port
Use this function to select the switcher's interface port to be connected to an exter-
nal LTC 8016/90 Allegiant Bilinx Data Interface accessory unit. Move the joystick up
or down until the desired port for use as a data interface (DIU) is displayed. Press
[Enter] to configure the port. If using the LTC 8555 keyboard, press [User] to exit the
mode.
User Function 40 - Reserved Function
User Function 41 - Set Satellite Communication Format
This function provides three (3) configuration options that determine the behavior
and content of the data commands issued by a master system to a satellite system.
In most cases, it is only necessary to change the default setting if using a multi-level
cascaded Allegiant satellite system configuration. (see Section Appendix A "Satel-
lite Systems," on page 107 for more information on satellite system configurations.)
Detailed descriptions of these options are listed below.
After entering the mode, move the joystick up or down to select the desired option.
Enter a valid user password, and press [Enter].
CACHE REM CAM option (default factory setting). In this mode, satellite com-
•
mands are issued repetitively, regardless of whether the satellite camera is still
being viewed by an operator. This mode of operation is more desirable in stan-
dard systems because it minimizes delays when previous satellite cameras are
reselected. It is not recommended for use in cascaded systems. In cascaded
systems, this mode could result in all available trunk lines coming from the 3rd
level satellite system to become used up, making them unavailable to the opera-
tors at the intermediate system.
NO REM CAM CACHE option. In this mode, after the top level operator selects a
•
locally connected camera, the trunk line between the top level and the interme-
diate level system will immediately be reset to its start-up camera (as defined in
the Monitor Table of the LTC 8059/00 MCS). This in turn frees up the trunk line
between the intermediate level system and the 3rd level system so it will be
available if needed by an operator at the intermediate level system.
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 avail-
able) 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 cam-
eras 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.
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 com-
mands 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 imme-
