Video decoding formats cover interlaced and progressive HDTV formats as well as SDTV for both 50 and 60 Hz. Both digital and analogue video outputs are available. The BitLink Decoder comprises of a 1RU rack-mounted, forced-air cooled frame. Modular Approach The BitLink Decoder was designed with modularity as a key criteria. This modularity facilitates easy adaptation to a number of different, and in some cases not so obvious, decoding/DTV applications.
2. Installation Injury Precautions WARNING! If handled improperly, this equipment can be hazardous under certain conditions. During servicing, this equipment must be handled with care to avoid high voltage electric shock Below are precautionary measures that must be considered before operating the BitLink Decoder Do not operate without lid To avoid electrical shock or fire hazard, do not operate this product without lid properly attached to the units. Only qualified personnel should perform servicing.
To prevent product overheating, provide proper ventilation and do not obstruct the ventilation areas on the units. Do not operate with suspected failures If you suspect there is damage to the products, have it inspected by qualified service personnel. Do not attempt to repair the failure even if you suspect it may be a minor problem. Packaging Visual check When you receive the BitLink Decoder, examine the package for obvious signs of damage. The delivery should not be accepted if the packaging is damaged.
Electrical power connection WARNING! The equipment must be grounded to avoid electrical shock. Failure to ground the unit may cause equipment damage and/or personal injury. Particular attention should be given to supply connections when connecting to power strips rather then direct connections to branch circuits. Physical Data Height 1RU Width 19” (483 mm) Depth 18.1” (461 mm) Weight (approx) 1) 9 kg Power (Max) 1) 60 W Voltage 90-120 V /60 Hz Fuse 2.
The BitLink Decoder can be mounted directly in a 19” rack, using the supplied rack mounting hardware (for both front and rear side). WARNING! Do not put any extra weight on top of the BitLink Decoder when mounted in a rack.
Brackets attached to BitLink Decoder WARNING! Always use two screws per side to secure the brackets. Connecting Transport Stream Input Ensure you have a valid transport stream on either the ASI or the RF (demodulator) input. Default (out of the box) setting is ASI 1. Note! Coaxial cables for ASI inputs and outputs must be double-shielded. Video Output Use one of the video outputs and connect to your monitor. Note! Coaxial cables for SDI outputs must be double-shielded.

Audio Audio Output The settings below are valid for the selected Audio Output. Service The service selection provides a list of available audio streams found in the transport stream. The selection is output to the selected audio output.
Setup Event Severities Sets the severity of different events to be indicated in the Event History, the Front Panel and the Alarms connector. Note! The severity Message will not be indicated on the front panel or Alarms connector. See Appendix B for default severity levels. Date & Time Sets date and time for the BitLink Decoder. Important for the Event History. Boards Displays the hardware version, FCO level on the different modules and in which slots they are mounted.
Status TS Info Provides information on input TS stream such as program number and PIDs. Decoding Provides information on current decoding program such as name and PIDs. Inputs Information on whether the BitLink Decoder is locked or unlocked to the external video reference. RF Status RF Level is the RF input level in dBm. Frequency Offset is the carrier frequency offset in Hz. Eb/No Estimate in dB. Error Rate Before RS (Reed Solomon) byte rate/s. Error Rate After RS in bits/s.
Log Live Last Events Provides information on the latest event for each severity type. Event History The Event History provides a list/log on all events since the Clear Log button was pushed.
Upgrade The Upgrade page allows easy software updates. Just follow the instructions.
6. Serial Control General Serial control from 3rd party controllers is possible via the RS232/RS422 interface. To obtain a copy of the BitLink Decoder serial control protocol, a NDA has to be signed.

7. Connections General The BitLink Decoder has a wide range of input and output interface modules available and can be configured in a number of different ways. The following sections will describe the different modules and their connectors. ASI module The ASI module provides dual ASI transport stream input and outputs. Note! This module is optional. ASI Out 1/2 DVB-ASI output, BNC 75 ohm (looped from input or any other TS input module). ASI In 1/2 DVB-ASI input, BNC 75 ohm.
8/QPSK Demodulator module (DEM) The DEM module is an L-Band RF QPSK/8PSK/16QAM demodulator (950 – 2150 MHz) with two inputs. Note! This module is optional. 8/QPSK In 1/2 2x F-type 75 ohm. These inputs can be routed to ASI outputs. Note! If both inputs are connected to signals with the same frequency and bitrate, the signal strength need to be reduced to –55 dBm, due to cross talk of –25 dBm between inputs. Note! Only one input at the time can be used.
VGA VGA HD output (RGBHV). Note! Only active for HDTV and if YPbPr is selected, the VGA output does not have a valid signal. R/Pr Pr Colour difference signal or Red depending on the mode chosen in the menu Output > Video > Analogue Format SDTV and HDTV respectively. G/Y/CVBS Luminance or Green analogue output or Composite PAL/NTSC output depending on the mode chosen. B/Pb Pb Colour difference signal or Blue depending on the mode chosen.
System Controller module (QMC) The System Controller module (QMC) provides an external remote/control interface. RS232/422 The RS232 port is used for 3rd party control of the BitLink Decoder. To obtain protocol information, see Serial Control, page 35. See Appendix A for pin-out. Ethernet The Ethernet connection is used for the Web interface (see page 25) and to upgrade with new software. Alarms/Control The Alarms/Control connector is reserved for Alarm relays output and future implementation of GPI.
