Control (Continued)
Active Front Panels and RollCall PC programs use
a RollCall connection to control a module.
RollTrack does not use a connection, it uses Blind
control. Blind Control is the ability to control a unit
without a connection.
This will disconnect the currently displayed
connected controller.
Connection
This displays the address of the connected
controllers. The Show Session control can be used
to scroll through the connected controllers.
Packet counts from this controller, and from all
connected controllers are displayed to the right.
Blind
This will display the address of last controller to
send the module a blind control packet.
Packet counts from blind controllers is shown to the
right.
Allow Blind Control
If the module will be controlled by Blind Control
(RollTrack and some third party remote control
systems) then Allow Blind must be enabled.
If Blind Control is not used then Allow Blind may be
disabled, giving protection against incorrectly set-
up RollTrack sources.
Single Session Only
When checked this allows only one connected
controller to control the module at any one time.
