Accom WSD via SCSI

You can control the Accom WSD videodisk directly via a SCSI connection.

Syntax

If you have multiple Accom WSDs on your network, you may want to create a configuration entry for each one. The syntax is:

device video controller name
          server_name server
          server_id socket
          server_host host
          buffer buffer
          display display
          defn
                    name device_name
                    format format
                    bypass mode
          enddefn
enddevice
device video controller name

The name is the name you want to assign to this device.

server_name server

The server is the name of the executable that controls the Accom WSD. It resides in the product_bin. The server should be vtcaccom for the Accom WSD.

server_id socket

The socket is the socket number through which your application communicates with the Accom WSD server process. This number must be unique to your UNIX system for each defined device and (Alias|Wavefront and non-Alias|Wavefront) server process. If you are defining multiple Accom WSD configurations, you must use a different socket number for each Accom WSD.

server_host host

The host is the name of the workstation on which the server executes. In SCSI mode, it is the name of the workstation to which the Accom is connected. The host name is typically the workstation on which you are running your application.

If a different workstation is being used as the server, you must ensure that your application has been installed on that server workstation as well. If you are accessing an Accom WSD from many workstations, you must ensure that each workstation's configuration file defines the same host (and not localhost) for that Accom WSD server process.

buffer buffer exclusive

The buffer is optionally used to set the frame buffer to open when the Accom WSD is opened.

display display

The display entry is optionally used to specify how you want the disk location to be displayed. The default, timecode, displays disk locations using time code. To display disk locations as frame numbers, specify frame. Note that this setting does not affect the display format on the Accom WSD console.

Device-specific statements

name device_name

The device_name is the filename used to specify the SCSI device. The format of the SCSI filename is: /dev/rdsk/dksSCSI_busdSCSI_addrvol

SCSI_bus can be:

0 for SCSI Bus 0 (for Indy's and Indigo's)
1 for SCSI Bus 1 (for Indigo²'s and Impact's)

SCSI_addr is the SCSI address of your device. The possible values are 0-7.

For example, /dev/rdsk/dks0d6vol is the SCSI filename for a device with SCSI bus 0 and SCSI addr 6.

Check the SCSI configuration menu on the Accom WSD status monitor to determine the SCSI address of your device. Consult the WSD Installation and Operations manual for details about the SCSI installation.

format format

The format indicates whether your Accom WSD recognizes NTSC or PAL video. If this line is omitted, NTSC is used by default.

bypass mode

The mode indicates whether the D1 video input port is on or off. If off, the Accom WSD expects to receive images via SCSI port. This is the default. If on, the Accom WSD expects to record from the D1 video input port. This requires a D1 video frame buffer.
