Page 28: About The Gui Interface
There is a menu item you can select to automatically clear the GUI from the outputs when you put Diskus into play or record mode. This prevents recording the GUI if the main output is the same as the GUI output.
Page 29 About the GUI Interface Diskus Operations The GUI consists of a number of windows superimposed on the video output. You use a mouse to move a cursor around the screen, and select GUI elements with the mouse buttons. The mouse cursor comes in two shapes; each is responsible for different control functions.

You can think of Diskus as a server that lets the rendering engines and computers in a graphics lab transfer animation sequences or rendered images. In addition, there are no preroll problems like those associated with single frame edits using a VTR.
Page 119: File Formats
Both the 8 and 10-bit formats are supported. 8-bit is the default file format for recording to Diskus 2 bit RGB files transferred to Diskus are stored as 10-bit YUV files on the disk. Using the extension .rgb8 for the file transfers causes Diskus to store them as 8-bit YUV files.
Page 120: Workstations
Once remotely logged in, you can set up and run utilities in the client remotely. With Diskus, you will rlogin to Diskus. The Unix workstation is the server, and Diskus is the client.
Page 121: The Rsh Command
Workstations Diskus Operations The rsh Command With Diskus, rsh lets you operate Diskus remotely from the workstation. rsh is a single-command interface that lets you control Diskus without logging in. Example of an rsh session: At the workstation % prompt, type rsh diskus play.
Page 122: File Transfers

Page 134: Superuser Commands
Some of the commands are only available to SuperUsers. You will need to execute the su command before using these commands. Diskus ships without a password, so SuperUser usage is always permitted through the su command. Once a password is set, using the passwd command, you must use it every time you request SuperUser privileges.

Page 136 Ethernet Commands Syntax: cue in|out|<position> Allows Diskus to cue to a location that is not on the disk. This can be used in conjunction with the "vplay" command and the "record on" command to do editor-controlled rolls. Move to the in point, out point, or specified position in frames or timecode.
Page 137 SuperUser. A clip list shows read and write privileges in three groups: user, group, and others. A typical listing following an ls -l command might be: diskus% ls -l -rwxrwx --- clip2 This shows that the user and group have read, write, and execute privileges, but others have no privileges.
Page 138 Diskus Operations Ethernet Commands Example: Set owner privileges to read, write, and execute on a clip named "clip2." diskus% chmod 700 clip2 diskus%ls -l -rwx------ This gives the user all privileges, but denies the group and others permission. Note that the "mode" command 700 sets privileges in octal.

Page 195: Scsi Operations
Diskus Operations SCSI Operations Overview Diskus supports the fast and wide implementation of SCSI-2. SCSI is used to archive material in digital format, recorded on the disk recorder, and to restore material from archive media back to the recorder. Diskus currently supports Exabyte 8 millimeter tape drives (Models 8200, 8500, and 8505).
Page 196: Tape Drive Operation
Diskus Operations SCSI Operations Tape Drive Operation Before archiving video from Diskus or recovering video from a tape cartridge, each tape drive must have been turned on and the green indicator on the front panel must be lit. For further operating information, see the Exabyte User’s Manual.
Page 197: Recovering Video From Tape To Disk
Exabyte EXB8200, EXB8500, or EXB8505 series tape drive and record the video on disk. The procedure assumes that you are starting with both Diskus and the Exabyte drive powered down. NOTE: You must restore the material in the same format as it was archived.
Page 198: Other Scsi Modes
Diskus Operations SCSI Operations the length of the recording. The system calculates the out point if you enter the length, or calculates the length if you enter the out point. STEP 6: Press the Mode button and select Restore. STEP 7: Click on the Status button to start the video recovery.
Page 199: Overview
A clip is a specific continuous part of disk storage length with its own separate parameters and attributes. You can define any length of Diskus storage as a clip, from a single field to the entire disk length. Each clip has a unique name, an in point, and an out point.
Page 200 Mode. For example, in the figure above clips 2 and 4 both have Record Lock enabled. Clips 3 and 4 have offsets. In the Transport window, you can place Diskus in clip constrain mode by choosing a clip from the Disk Define List. In clip constrain mode, Diskus only records or plays back within the current clip.

Page 202: Clip And Segment Comparison
Diskus jumps to the beginning of the next segment when it finishes playing the current segment. Note that Diskus drops the first field of the second and third loops of segment 4 to maintain a proper field 1/2 relationship. This means that a segment with bounce loop enabled is always one field shorter than a segment with a normal loop.
Page 203: Defining A Clip
Diskus Operations Clips and Segments Defining a Clip You can define a clip with the Transport window. STEP 1: Open the Transport window Move the cursor outside any open windows, and press the left mouse button. This brings up the List window.

Page 351: Thicknet
Diskus Technical Guide Ethernet Setup There are three popular ways to connect devices to an Ethernet network: Thicknet, Thinnet, and Twisted Pair. Thicknet Thicknet, sometimes known as 10-Base-5, uses a thick coaxial cable, usually yellow. This cable runs close to all the devices on the network.
Page 352: Thinnet
Ethernet Setup Diskus Technical Guide Thinnet Thinnet, sometimes known as 10-Base-2, has recently become more popular. It uses a thinner coaxial cable, and connection involves cutting the cable and attaching BNC connectors. If the device has an internal transceiver, a BNC ’T’ piece connects the two ends of the Ethernet cable to the BNC connector in the device.
Page 353: Twisted Pair
Diskus Technical Guide Ethernet Setup Twisted Pair Twisted pair Ethernet, sometimes known as 10-Base-T, is a comparatively new method of Ethernet connection. It uses a thin cable and a small multi-pin RJ-45 connector (similar to that used in a modern telephone). Rather than a single cable looping to all the devices on the network, each device connects to a single "hub."...
