U NITY 4600 USER’S MANUAL Table 1.3: Term Automated Recovery (or Recovery) Glossary of Terms Definition The mechanism used when the U4600 is unable to acquire a valid transport stream, loses network control or detects an invalid control stream, or is unable to deliver the required services using its current settings. The unit automatically begins attempting operations under "backup" unit settings stored in the presets table until it can return to normal operation or is stopped by local user command.
Unity 4600 User’s Manual Table 1.3: Glossary of Terms Term MPEG Definition Moving Picture Experts Group - refers to the method of video compression established by this group. (The Unity 4600 utilizes the MPEG2 format for video.) Network Protection A non-volatile setup parameter whose value is “Shared” or “Protected” (or “not Shared”). Similarly, Mode each network control stream has a “Share” status field as part of the COMPEL packet framing.
U NITY 4600 USER’S MANUAL Table 1.3: Term Glossary of Terms Definition Service Descriptor Service Descriptors are text entries in the Service Descriptor table (SDT, defined per a DVB standard). Service Descriptors are used to give text names to the Programs within transport streams. Service Settings That part of the Unit Settings which allow for the local detection, decompression, and output (or "display") of a program's services.
UNITY 4600 USER’S MANUAL CHAPTER 2 INSTALLATION This chapter provides instructions on unpacking, mounting, and connecting your U4600 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.
U NITY 4600 USER’S MANUAL Mechanical Loading Rack-mounted equipment should be installed in such a way that a hazardous condition is not produced by uneven loading. The U4600 unit is not very heavy, but total rack loading must be considered. Also, do not rest any unsupported equipment on a rack-mounted U4600 unit.
UNITY 4600 USER’S MANUAL 2.3 U4600 Connections Figure 2.1 shows the connector locations on the U4600 rear panel. See Figure 2.2 for Transport In Options for this slot. Figure 2.1: U4600 Rear-Panel Connector Locations Figure 2.2 Unity 4600 Transport-In Options below shows rear-panel views of the five available receiver modules.

UNITY 4600 USER’S MANUAL Device Handling Terminal I/O The Terminal option is used for command and control of the U4600. The Terminal option provides a basic VT100-like terminal emulation. All I/O is prompted by user-input text strings terminated in carriage-returns. The Terminal, whether local or remote (via modem or telnet over TCP/IP), should be set to Local Echo On. The unit only echoes a carriagereturn/linefeed and then a ‘>’ prompt after user entry.
U NITY 4600 USER’S MANUAL 3. 2.5 The last type, Raw COMPEL Data, must also be enabled by a non-volatile control. (Actually, it is a factory setting that can only be modified with debug access.) When this type of COMPEL data stream is being processed normally by the IRD host processor, it is also output as-is (in binary witn non-printing characters) to the Printer.
UNITY 4600 USER’S MANUAL DTMF Setup This test allows the setup of DTMF tone levels and verification of connections to cue equipment. Use the following steps to set the DTMF level: a. From the Audio/Video Check screen, press the right-arrow button to display the DTMF Setup screen. b. Press ENT to display the DTMF Test Tone screen and begin output of the DTMF test tones. The tones (actually tone-pairs) are played out at about one-second intervals from 1 through 9, 0, *, #, A, B, C, D, and then repeating.

UNITY 4600 USER’S M ANUAL Chapter 3 Operation This chapter provides an overview of Unity 4600 operation, details of controls and indicators, the alarm/warning system, and user interface details. 3.1 Theory of Operation Functional Summary From one selected RF input feed, the Unity 4600 receives an L-band RF carrier from an external antenna LNB. It then demodulates the carrier and extracts the transmitted MPEG transport stream.
U NITY 4600 USER’S MANUAL Several user- or network-programmable objects control the Automated Recovery. In addition to the contents of the Preset Table, these objects include the Services Recovery Timeout, the Network Recovery Timeout, the Recovery Iteration Time, and the Local Control Reenable Timeout. The first two timeouts control how long the unit will wait after loss of services or network control, respectively, before entering Automated Recovery.
UNITY 4600 USER’S M ANUAL 3.2 Operation from Front Panel The U4600 front panel (Figure 3.2) includes the following four main parts: a liquid crystal display (LCD), six pushbuttons, eight LED indicators, and the front-panel audio and video monitor ports. Essentially all control available through the network or terminal is also available from the front panel. The front-panel LCD (1) on Figure 3.

UNITY 4600 USER’S MANUAL CHAPTER 4 MAINTENANCE AND TROUBLESHOOTING 4.1 Maintenance Maintenance of the Unity 4600 is limited to keeping the chassis clean and ensuring that all the cables remain firmly connected. Occasionally wipe the exterior with a soft, damp cloth to remove any accumulated dust and dirt, and check that the cables are securely attached. The Unity 4600 incorporates security labels over some of the screws. There are no user-serviceable components within the U4600.

If a spectrum analyzer is available, look for the carrier at the L-band intermediate frequency. (For domestic Cband satellites, this is 5150 minus the downlink frequency in MHz.) b. The selected IRD RF port has failed.
UNITY 4600 USER’S MANUAL 4.3 Alarms and Warnings The alarm and warning system is intended to alert the local user of a present or impending loss of services. Table 4.1 below lists many (but not all) of the possible alarm and warning messages that the U4600 may display. For problems you cannot resolve on your own, please contact Wegener Customer Service (see Chapter 5), and be prepared to describe your signal setup, U4600 configuration, and any displayed alarm and warning messages.
UNITY 4600 USER’S MANUAL Table 4.1: Alarm and Warning Descriptions LCD Alarm or Warning Message Auto-Recovery Meaning / Possible Cause Auto-recovery in progress. This may be caused by any of the following problems on a previously commanded or successfully acquired transport stream: 1. IRD unable to deliver services for time exceeding Services Recovery Timeout; 2. IRD required to maintain connection to COMPEL and IRD has not detected COMPEL for time exceeding Network Recovery Timeout; or 3.
UNITY 4600 USER’S MANUAL Table 4.1: Alarm and Warning Descriptions LCD Alarm or Warning Message Meaning / Possible Cause Invalid COMPEL Hdr Invalid COMPEL header detected in incoming COMPEL messages. This will cause the unit to immediately attempt automatic recovery to a backup preset. The IRD is not set up for connection to this COMPEL system. Invalid VBI Data Fmt VBI data found in PID or video user data in unrecognized or unsupported format (protocol).
UNITY 4600 USER’S MANUAL Table 4.1: Alarm and Warning Descriptions LCD Alarm or Warning Message No Def for Mapping Meaning / Possible Cause ASI transport output bears no program content because an Output Definition Table has not been loaded from the network. Contact network TOC. No DHCP Server Found IRD is required to get IP settings from DHCP server but none are detected on the LAN. No Genlock Sync IRD supports and has genlock option installed and enabled, but no video reference sync is detected.
