Sierra Design Labs Quick Frame via SCSI

You can control the Quick Frame videodisk (also known as the HP VDR) directly via a SCSI connection. If multiple workstations are connected to your network, you can access the Quick Frame from any workstation that has Ethernet access to the workstation the Quick Frame is connected to.

Syntax

If you have multiple Quick Frames, you may want to create a configuration entry for each of them. The syntax is:

device video controller name
          server_name server
          server_id socket
          server_host host
          buffer buffer exclusive
          display display
          defn
                    name SCSI_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 Quick Frame. It resides in the product_bin. For the Quick Frame, server should be vtchpvdr. (If you relocate the server executable, or if the server is running on a different host than your application, you must specify the server as a full UNIX pathname.)

server_id socket

The socket is the socket number through which your application communicates with the Quick Frame 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 Quick Frame configurations, you must use a different socket number for each Quick Frame.

server_host host

The host is the name of the workstation which is connected to the Quick Frame. The host name is typically the workstation on which you are running your application, but can be any of the workstations on your Ethernet network. If a different workstation is being used, you must ensure that your application has been installed on that server workstation as well. If you are accessing a Quick Frame from many workstations, you must ensure that each workstation's configuration file defines the same host (and not localhost) for that Quick Frame server process.

buffer buffer exclusive

The buffer is optionally used to specify the frame buffer to open when the Quick Frame is opened. Use the keyword exclusive to specify that the Quick Frame can access only this frame buffer. For information on the Quick Frame video frame buffer device, see page 319.

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 Quick Frame 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/scsi/scSCSI_busdSCSI_addrl0

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/scsi/sc0d6l0 is the SCSI filename for a device with SCSI bus 0 and SCSI addr 6.

After the SCSI_addr, the l0 is a lower-case L and a zero.

Check the SCSI configuration menu on the Quick Frame status monitor to determine the SCSI address of your device. Consult the Quick Frame manual for details about the SCSI installation.

Tip: Make sure that the SCSI device name you use is readable/writable by all mode 666 and that is set up for SCSI control mode.
