Setting Up Video Hardware
The following procedure describes how to configure the hardware for VTR emulation. Consult
the "VTR Emulation" chapter in the User's Guide for your Editing application for more
information.
To configure hardware for VTR emulation:
1. Connect the video I/O cables between the devices involved in the VTR emulation process
(out-to-in/in-to-out). Make sure the connections support the video standard you want to
work with.
If you intend to use the emulator as a Player, it is recommended that you connect one black
or colour bar SDI signal to the input of the system serving as the VTR emulator. This ensures
the Player is stable and correctly synced.
N :
VTR emulation requires an Editing workstation with a video board. The Video keyword
OTE
for the corresponding device must be uncommented in the software initialisation
configuration file. See the description of the Video keyword in the Configuration File Reference
Guide for Linux Workstations for your release.
Connect the audio I/O cables between the devices involved in the VTR emulation process
2.
(out-to-in/in-to-out).
If you intend to use the emulator as a Player, it is recommended that you connect an external
AES signal such as a tone to the input of the system serving as the VTR emulator. This
ensures the Player is stable and correctly synced.
N :
Connect an RS-422 control cable to the serial ports between the devices in the VTR
OTE
emulation process. Make sure the serial ports correspond to those defined by the Emulator
keywords in the software initialisation configuration file, init.cfg. See the description of the
Emulator keyword in the Configuration File Reference Guide for Linux Workstations for your
release.
N :
The RS-422 cables for VTR emulation require custom pinouts. See
OTE
Control Cables"
Make sure the appropriate video and audio sync setup is in place.

VTR Emulation RS-422 Control Cables
Custom cables are required to control the VTR emulator. The pinouts required by the cable
depend on the workstation and device involved in the VTR emulation process. The following
diagrams depict the control cable pinouts required for the most common VTR emulation
setups.
