This function allows information about the status of
the unit to be communicated to other RollTrack
compatible modules connected to the network.
This message can then be used to cause another
unit to perform a specific action. Up to 10
RollTrack communication channels to compatible
modules may be selected from the RollTrack 1-5
and 6-10 screens.
Each of the RollTrack channels may be set to the
following modes:
Off
Function is not used.
Delay
Video delay through the unit.
I/P Loss
The input signal has been lost.
I/P Restore
The input signal has been restored.
Unit
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.
For details of the RollCall command numbers for
specific units please contact your local Snell &
Wilcox agent.
The unit address has three sets of numbers.
For example: 0000:35:02
The first set (0000) is the network segment code
number
The second set (35) is the number identifying the
(enclosure/mainframe) unit.
The third set (02) is the slot number in the unit
Parameter
To make the destination unit perform a particular
function a RollCall command number must be
entered using this function.
To add/change the number type the number in the
text area and then select
(return).
(Preset) returns to the default number.
The Parameter has three sets of numbers. e.g.
100*001*000 (command 100 is memory recall and
parameter 001 means recall memory 1 on a
NRS70).
The first set (100) is the command or channel
number.
Note that channel numbers 14, 15, 16 & 17 should
be used for audio delay cards.
The second set represents the parameter. For
delay it is automatically inserted by the NRS70 and
represents the delay through the unit that is
communicated to an audio delay card.
The third set is the RollCall unit ID and it identifies
the board type. When the third set is not (000) the
RollCall ID has to match at the correct RollCall
address otherwise no action will take place.
