Device Transport Commands
The Device Transport Commands allow you to use
custom control buttons to send transport commands, such
as play, stop, rewind, and pause, to a device using the
Betacam protocol. Transport command buttons are tallied
for the status of the device.
Transport commands are set up for a single device
connected to an input BNC. If you need to control
multiple devices, you must set up additional custom
controls for each device.
To Set Up a Device Transport Command
Note: Device transport commands can only be added to a
Transport custom control bank.
1. Press HOME > Custom Controls.
2. Use the Bank and Button knobs to select the
custom control that you want to record to.
3. Press Assign Button > VTR.
4. Use the BNC knob to select the VTR that you want
to assign the transport command to.
This is the VTR that the custom control will send
the commands to.
5. Use the Function knob to select the command you
want to assign to the button.
6. Press Insert.
Only a single command can be programmed into the
custom control.
Variable Pause
You can place a command in a custom control that will
stop, or pause, a custom control where the pause is placed
in the custom control. The length of time that the custom
control is paused is set as the result of the Pause Equation.
Variable pauses are commonly used to insert pauses into
custom controls to compensate for satellite uplink latency.
For example, you can use a variable in all your custom
controls where you need to sync with a satellite feed.
You can then adjust that variable for changes in latency,
and all your custom controls that use that variable are
updated.
To Set a Variable Pause Value
Tip: Press Reset All to set all the variable to the default value
(0).
1. Press HOME > Custom Controls > More > Set
Variables.
2. Use the Variable knob to select the variable that
you want to set a value for. If you change the value
of a variable, all equations that use that variable will
be changed.
3. Use the Frames and Seconds knobs to select the
length of time that you want to the variable set to.
The number of frames for each second depends on
the video format the switcher is operating in.
To Insert a Variable Pause
1. Press HOME > Custom Controls.
2. Record your custom control to the point where you
want to insert the pause and press Insert Special
> Special.
3. Use the Function knob to select V Pause CC.
4. In the Enter Pause Eq'n eld, enter the equation
you want to calculate the length of the variable
pause.
The equation can be any combination of variables
that are added (+), subtracted (-) or multiplied (*)
together. Negative numbers, division, and spaces
are not supported. Side-by-side variables are
multiplied together (AB=A×B).
