Adjusting VTR Control for Recording from Tapes

SL NEO servers of 1000 and 3000 series allow controlling one or several recorders (VTR) for recording from tapes. Management is implemented by the interfaces RS232/422, by the protocol SONY 9 Pin Remote Protocol, or by the interfaces IEEE1394 (FireWire).  

Step 1. Connect the tape-recorder.

You should connect the port of controlling the tape-recorder to the server, or to any other network client station. The server has at least one RS-232 control port (COM) placed at the back wall of a system block. If the tape-recorder has the control interface RS-422, you may use the converter of interfaces or the board that contains the appropriate ports; you can also make a cable 422-232 (see the description of the server).

Step 2. Configure server software for controlling the VTR

Further settings will be implemented at the machine that is physically connected to the interface of controlling the tape-recorder. When connecting the tape-recorder to the control port of the client station, you should preliminarily install a set of SL NEO software onto the station. 

 

Stop the server software components, add a new device to the system.

 

By the right click on the blue icon SL NEO in the taskbar, choose Stop Server and stop the server components. When the icon becomes red, right click on it and choose the item Configure Server Components. Open the setting window, find the new device VTR in the field Available components and add it into the right field.

 

Launch server software (right click on the SL NEO icon in tray and choose "Start Server")

Login to the console is implemented locally from the server, or from any machine in the network by the address http://ip address:7901. You should login to the control console as an administrator. 

 

After the login to the control console, choose Manage at the left menu of the console. Item VTRs allows users to configure SL NEO Device Server (a module for managing VTR-devices). Choose the tab VTRs, click Service Enabled in the window VTR1. Find the field VTR parameters and choose the mode of work with video, type of management interface and the port number. 

 

Press Apply Changes (at the top part of the server control console), to save the settings.

Step 3. Connect VTR Device Server to the recorder

The settings will be implemented fromAdministrator Control Panel. After the login to the control console, choose Manage from the left menu, then choose the tab Recorders. Find the field VTR address and specify the IP address of the machine that is physically connected to the recorder and has the configured Device Server, or leave the field empty, if it's connected directly to the control port of the server. Leave the value VTR number as "1" (for the service VTR1). 

 

Press Apply Changes (at the top part of the server control console), to save the settings.

Step 4. Configure client software Air Manager

Choose File/Configure. The tab Services serves to configure Air Manager connection to the record and playback services and VTR management services (VTR Device Server).

 

In the window VTR Services you should set up the parameters for connections of Air Manager to the VTR control service. Find the field Host and enter the IP address of the PC that is physically connected to the management and has the configured service VTR Device Server. The field Num should contain the number of the service ("1" in our example). In the field Description specify a random name for the VTR (for example, VTR1, VTR2).

 

You can launch control of the tape-recorder from lines of the REC-list that controls the recorder connected to Device Server (see Step 3). To activate VTR control from the REC-list line, choose the value VTR in the field Source.  

 

Source – the type of source that is used for recording to the video server within the framework of a given line. There are two types of sources for recording:LIVE and VTR

 

LIVE is a non-manageable source chosen by default when creating a new line. It formally means recording a signal from an external line switched manually to the corresponding server input.

 

In case, if you choose VTR as a source, the function of control of the VTR-device becomes activated. The VTR will operate in the playout mode and the materials will be recorded from it onto the server. In case of using the VTR source type, it is necessary to fill the appropriate rec-list line with the values In Point and Out Point that correspond to the LTC values on the videotape.
