Remote Control Support
Use the information in this section to assist you in setting
up an external device to control your server.
Remote Communications (RS-422)
Direct serial control of each channel transport on the
server is available through the RJ45 ports on the breakout
cable connected to the server. Ethernet communications
can also be used to control a channel transport instead
of the direct serial connection.
The first RJ45 port provides control over channel
transport A, the second port provides control over channel
transport B, and so on.
Note:
RJ45 to DB9 converters are provided in the installation
kit if needed.
To Configure Remote Communications
Each channel transport on the server has a dedicated
RS422
port for serial control over that channel transport.
The communications settings are stored to Rooms, which
are then assigned to channels. Ethernet control is also
supported.

room to a channel.
4.
In the
RS422 Protocol
area, select the protocol
you want to use.
•
BVW-75
— Sony
®
BVW-75 protocol. Does not
support clip library listing or clip loading.
•
Odetics
— Odetics protocol.
•
VDCP (Louth Protocol)
— VDCP/Louth
protocol over serial or ethernet.
•
AMP over Ethernet
— AMP protocol over
ethernet - no serial connection required.
Tip:
If you select VDCP, you can restrict the Get Clip List
command to a specific folder. Select the folder you want to
restrict the clip list to in the Restrict Folder area.
5.
In the
Response Time
area, select how quickly
the server executes the Clip Play command after the
Clip Load command.
•
Fast
— executes the play command immediately
after the load command. This is recommended
when controlling the server from an external
switcher.
•
Accurate
— executes the play command only
after receiving confirmation that the clip has
loaded. This is recommended when controlling
the server from an automation system.
6.
If you selected the VDCP protocol, select the type
of communications you want to use in the
Channel
Control Port
area.
•
RS422 Serial Port
— use RS422 serial
communications.
•
Ethernet Port
— use ethernet communications.
Note:
When controlling the server from a remote device
over ethernet, you must set the port on the server
corresponding to the channel you want to send
commands to. Channel transport A = port 8000, channel
transport B = port 8001, and so on.
7.
In the
Edit Timing
area, select a timing offset for
when you are controlling the server from an external
editor over serial.
•
Timecode Alignment
— select the offset, in
frames, of the timecode information that is sent
to the editor during playout or record.
•
Source Alignment
— select the offset, in
frames, of the timecode information that is sent
to the editor during playout.
•
Out Point Offset
— select the offset, in fields,
of the out-point timecode value that is sent to the
editor during record.
8.
In the
Video Edit Effect
area, select which tracks
get recorded when an external editor issues the Video
Record command to the server.
•
Edit Video Track
— only the video track is
recorded.
•
Edit Key Track
— only the alpha (key) track
is recorded.
•
Edit Video and Key Tracks
— both the video
and alpha (key) tracks are recorded. The clip
