Media Station|PT Installed as a Video Satellite
or Installed on the Same Computer as Pro Tools
If Media Station|PT is installed as a video satel-
lite of Pro Tools or installed on the same com-
puter with Pro Tools, connect the audio inputs
and outputs on the VTR to the audio inputs and
outputs on the primary Pro Tools|HD audio in-
terface.
Configuring MachineControl with a VTR
If the VTR is DV-based (which means it accepts
Deck Control via FireWire), connect the VTR to
the Media Station|PT computer via FireWire.
If the VTR requires 9-pin control, you need to set
it up differently.
Connecting a Serial 9-Pin Cable from the
Media Station|PT Video Satellite to the VTR
Because the VTR is always controlled by
Media Station|PT in a video satellite system, you
need to connect the video satellite computer di-
rectly to the VTR.
To connect a VTR via 9-pin to a Windows com-
puter:
 Connect the computer’s COM port to the
deck, using a 9-pin RS-322 to RS-422 cable (not
provided).
Connecting a serial 9-pin cable is not necessary
if you are using a DV-based VTR that accepts
deck control commands via FireWire.
In this case, the serial 9-pin cable is not neces-
sary since the FireWire connection between the
VTR and the Media Station|PT client computer
is sufficient. (See your VTR documentation for
detailed support information.)
Connecting a VTR to Mac OS X
To connect a deck to a Mac computer:
1 Connect a Keyspan USA28x USB serial adapter
(not provided) to a USB port on the computer.
2 Connect a male mini DIN-8 serial to male 9-
pin D-sub Deck Control cable (not included) to
the end of the adapter.
3 Connect the end of the cable to the deck.
Connecting Video Reference
If an Avid video peripheral is connected to the
Media Station|PT computer, it must have an ap-
propriate video reference signal (black burst).
To connect a video reference signal to your VTR:
 Connect a black burst or house sync output to
a video input on your VTR (preferably a refer-
ence video input).
The 9-pin RS-322 to RS-422 cable is in-
cluded with the Digidesign MachineControl
option, which is available separately from
Media Station|PT. See www.digidesign.com
for details.
You may need to install a Keyspan driver to
use the Keyspan USB serial adapter. See
your Keyspan documentation for details.
The male mini DIN-8 serial to male 9-pin
D-sub Deck Control cable is included with
the Digidesign MachineControl option,
which is available separately from
Media Station|PT. See www.digidesign.com
for details.
Always make sure to connect the proper
black burst signal to your Avid DNA periph-
eral before opening a project.
