RollTrack
This function allows information to be sent, via the
RollCall™ network, to other compatible units
connected on the same network.
For example, it can enable compatible audio delay
units to produce an audio delay dependent on this
and other similar units. The audio delay unit will
dynamically follow or track the received delay-time
information. This allows processed video signals to
be timed correctly with audio signals. This
automatic tracking system via the RollCall™
network is call
RollTrack
.
For more detailed information, see the RollTrack
section (Appendix) at the end of this manual.
RollTrack Index
This item allows up to 70 destinations to be selected.

transmission of data to be selected. Options are:

The destination for the information is set by the
network code address as follows:
Network Address
This item allows the address of the selected
destination unit to be set.
To change the address, type the new destination
in the text area and then select
(return).
(Preset) returns to the default destination
The full
RollTrack
address has four sets of
numbers
For example: 0000:10:01*362
The first set (0000) is the network segment code
number
The second set (10) is the number identifying the
(enclosure/mainframe) unit.
The third set (01) is the slot number in the unit
The Fourth Set (362)
Each RollCall unit has a unique identification
embedded in the units’ software. In this example
362 represents an IQDMX00, 412 would represent
an IQDEC00, 161 a Mach 1 etc. Inserting this
number in the RollTrack address ensures that only
the correct type of unit (in this example an
IQDMX00) will respond to the RollTrack command;
any other unit will ignore the command.
If this number were set to 00
any type
of unit at
this location would respond to the RollTrack
command, possibly causing unpredictable results.
The unit ID of a module on the RollCall network
may
be
found
under
RollCall
Control
Panel/RollCall Listing/Unit Information
or via the
RollCall Control Panel
Help/About Current Unit
function
.
RollTrack Command
The full
RollTrack
command has two sets of
numbers
For example: 84*156
The first set (84) is the
RollTrack
command
number
Note that only command numbers 14,15,16 and 17
should be used for audio delay
