Unity 4650 User’s Manual 1.4 Safety Summary The U4650 is designed for safe use with few special precautions required of the user. The following items are basic precautions to use when installing and working with your U4650: Do not open the U4650 chassis cover. The U4650 incorporates security labels over some of the screws. There are no user-serviceable components within the U4650. Tampering with these security labels or opening the unit will void your warranty.
Unity 4650 User’s Manual Table 3: Glossary of Terms Term Definition Audio Language Descriptor Legacy 3-character MPEG descriptor applied to a program’s audio streams. It was originally allocated to designate languages, but is now used for generic identification.
Unity 4650 User’s Manual Table 3: Glossary of Terms Term Definition Extended windows Where decompression of 4:2:2 chroma sampled MPEG video is supported, the original encoder may be set to compress Vertical Blanking Interval (VBI) data in the same manner as the video in the active picture area. This mode where extra vertical resolution is supplied, is called Extended Windows by Wegener.
Unity 4650 User’s Manual Table 3: Glossary of Terms Term Definition Network Protection Mode A non-volatile setup parameter whose value is “Shared” or “Protected” (or “not Shared”). Similarly, each network control stream has a “Share” status field as part of the COMPEL packet framing. A network control stream is considered “invalid” to the U4650 if the network ID in the stream differs from that of the IRD and if either the network stream or the U4650 are set to be “Protected”.
Unity 4650 User’s Manual Table 3: Glossary of Terms Term Definition Program Number A numerical code representing a program. PSI Tables A group of information-bearing tables, each borne by well-known PIDs, regularly transmitted in the transport stream. See also “PAT” and “PMT”. Also, ISO 13818-1 gives a thorough description of these and other Tables. PTS Presentation Time Stamp. A marker signal associated with audio and video streams within a program conveyed in MPEG transport stream.
Unity 4650 User’s Manual Table 3: Glossary of Terms Term Definition Transport Loss, Signal Loss, or Carrier Loss Loss of transport stream, usually because of carrier-tracking loss, for a time period defined by a non-volatile factory setting. Transport stream can only be "lost" if the IRD has first passed the "Verified Transport" state at a particular carrier setting with no intervening change to carrier settings because of user (local or network) command or Automated Recovery.
Chapter 2 Installation This chapter provides instructions on unpacking, mounting, and connecting your U4650 as well as connector information including detailed pinouts. 2.1 Unpacking and Inspection Carefully unpack the unit and its ac power cord and inspect for obvious signs of physical damage that might have occurred during shipment. Any damage claims must be reported to the carrier immediately. Be sure to check the package contents carefully for important documents and materials.
Unity 4650 User’s Manual DANGER To avoid damage to this and other equipment, or personal injury, the following items should be strictly observed. Elevated Operating Ambient When equipment is installed in a closed or multi-unit rack assembly, the operating ambient of the rack environment may be greater than the room ambient.
Unity 4650 User’s Manual Rack Mounting Your U4650 is sized at a single RU and will fit an EIA-standard, 19-inch-wide equipment rack. a) First install angle brackets or cross-supports capable of supporting both the unit and its connecting cables. Screw or bolt the supports securely to the equipment rack. b) Place the U4650 on its supports and use four anchor screws or bolts and nuts to secure the U4650 front brackets to the rack. WARNING The front brackets must be secured to the rack.

Unity 4650 User’s Manual 2.4 Serial Port Configuration Device assignments The U4650 has one external serial port. A “device” must be assigned once to the serial port, but no “device” may be assigned more than once. In addition, more than one device may be assigned at one time but only one device which accepts input may be assigned. (If multiple devices are assigned to the serial port, the port’s settings are controlled by the device with higher priority according to the list below.
Unity 4650 User’s Manual Device handling Terminal I/O - The Terminal device is used for command and control of the U4650. This I/O is a basic VT100-like emulation. All I/O is prompted by userinput text strings terminated in carriage-returns. The terminal, whether local or (via modem) remote, should be set to local echo ON. The unit only echoes a carriage-return/linefeed and then a ‘>’ prompt after user entry. (But see Serial Bus Control below.
Unity 4650 User’s Manual Aux Data - The Aux Data device is defined to allow for async data streams to be carried within the transport stream and their raw payload output on an IRD serial port. The PID of these streams may or may not be assigned to a program number within a PMT. To recover the data, the IRD need only be given the PID and baud rate. The range of legal PIDs is established by the ISO 13818 standard as 20 to 1ffe (hex).
Unity 4650 User’s Manual Audio/video check This test puts out a video test pattern and audio test tones to allow verification of video and audio connections. The video pattern is vertical color bars. On Port 1, the audio is a slowly pulsing (triangle-wave) tone with a higher frequency on Right than on Left. On Port 2, the audio is a slowly pulsing (sinewave) tone also with higher frequency on Right than on Left.
Chapter 3 Operation This chapter provides an overview of Unity 4650 operation, details of controls and indicators, the alarm/warning system, and user interface details. 3.1 Theory of Operation Functional summary If an L-band receiver card is installed, the Unity 4650 accepts carriers in that band from an external antenna LNB and then demodulates and extracts the transmitted MPEG transport stream.
Unity 4650 User’s Manual Automated recovery If unable to deliver required services to predetermined standards, or if unable to detect a required network control stream (COMPEL), the U4650 attempts to resume normal operation through a process called Automated Recovery. Referring to an internal, non-volatile list of "presets", the U4650 will attempt to restore either services or network control, depending on what caused the recovery.

Tones will be output at the percentage of full-scale voltage indicated by level. If tone is supplied, then that tone is output continuously. If tone is omitted, then the IRD cycles endlessly through all tones, 1 second per tone. Disable with TESTOFF command.
Unity 4650 User’s Manual FORCERF port port:Either OFF or the numbers 1, 2, 3, or 4. Command to either disable or enable effective RF switch bypassing. If port is a number, then all subsequent carrier reception is sought at that RF feed port, regardless of the current Unit Setting. If port is OFF, then normal RF switch function is restored. Entering the command without parameters gives current status, either “Normal RF Switch”, or “Forced RF Feed Port n” where n is either 1, 2, 3, or 4.
Unity 4650 User’s Manual GLPHASE phase phase: Integer between -180 and +180 inclusive. Command to adjust the subcarrier phase of genlocked composite video output, relative to the reference. The offset in degrees is set by the phase parameter, with the actual register values set for the nearest 2 degrees of adjustment resolution. Positive settings of phase will force the video subcarrier phase to lead the genlock reference. For example, a setting of -10 directs the unit to use -9.9° of backward offset.
Unity 4650 User’s Manual LAN GATEWAY addr addr:IP address formatted as n1:n2:n3:n4 where n1, n2, n3, and n4 are integers between 0 and 255. Command sets the IRD’s static internet Gateway IP address. No protection is offered against entry of non-standard addresses (e.g. 0:0:0:0). Omitting the addr parameter shows the current static Gateway IP. This will not be the current Gateway IP address if dynamically assigned. Use IPCONFIG command for that.
