QAM256 Digital Video Modulator and Upconverter Introduction Introduction 1 This chapter provides an overview of the QAM256 Digital Video Modulator and Upconverter. The QAM256 may be referred to in this manual as “the unit”, or the modulator”. 1.0 Introduction The Radyne Corporation new DVB-compliant QAM256 Digital Video Modulator and Upconverter meet all DVB requirements for transmission of digital video over broadband coaxial cable and microwave radio.
Introduction 1-2 QAM256 Digital Video Modulator and Upconverter TM077 - Rev. 4.
QAM256 Digital Video Modulator and Upconverter Installation Installation 2 This section provides unpacking and installation instructions, and a description of external connections and backward alarm information. 2.0 Installation Requirements The QAM256 Modem is designed to be installed within any standard 19-inch wide equipment cabinet or rack, and requires one rack unit (RU) of mounting space (1.75 inches) vertically and 17¾ inches of depth.
Installation QAM256 Digital Video Modulator and Upconverter 2.2 Removal and Assembly Carefully unpack the unit and ensure that all of the above items are in the carton. If the Prime AC power available at the installation site requires a different Power Cord/AC Connector, then arrangements to receive the proper device will be necessary before proceeding with the installation. The QAM256 unit is shipped fully assembled and does not require removal of the covers for any purpose in installation.

QAM256 Digital Video Modulator and Upconverter Theory of Operation Theory of Operation 3 3.0 Theory of Operation A digital terrestrial interface supplies the modulator with a data stream. The data stream is synchronized if the incoming stream is framed. The data is scrambled, and FEC is added. The data is then convolutionally encoded, punctured, then constellation mapped. The resulting I&Q symbols are digitally filtered.

QAM256 Digital Video Modulator and Upconverter User Interfaces User Interfaces 4 4.0 User Interfaces Operation of the QAM256 consists of controlling the unit operating parameters and monitoring status and responses via one of the control interfaces. The two user interfaces available from the Front Panel are Front Panel Control, and Terminal Mode Control (not currently available). Either of these methods may be used separately or together to monitor and control the QAM256. 4.
User Interfaces QAM256 Digital Video Modulator and Upconverter 4.1.1 LCD Front Panel Display The front panel display is a 2 line by 16-character LCD display. The display is lighted and the brightness can be set to increase when the front panel is currently in use. The LCD display automatically dims after a period of inactivity. The display has two distinct areas showing current information. The upper area shows the current parameter being monitored, such as ‘Frequency’ or ‘Data Rate’.
QAM256 Digital Video Modulator and Upconverter User Interfaces 4.1.4 Front Panel LED Indicators Eight LEDs on the QAM256 Front Panel (Refer to Table 4-3) indicate the status of the QAM256’s operation. The LED colors maintain a consistent meaning. Green signifies that the indication is appropriate for normal operation, Yellow means that there is a condition not proper for normal operation, and Red indicates a fault condition that will result in lost communications. Table 4-3.

QAM256 Digital Video Modulator and Upconverter Maintenance and Troubleshooting Maintenance and Troubleshooting 6 6.0 Periodic Maintenance The QAM256 modulator requires no periodic field maintenance procedures. Should a unit be suspected of a defect in field operations after all interface signals are verified, the correct procedure is to replace the unit with another known working QAM256. If this does not cure the problem, wiring or power should be suspect. There is no external fuse on the QAM256.

Remote Operations QAM256 Digital Video Modulator and Upconverter C.1.2 Protocol Wrapper The Radyne COMMSPEC is byte-oriented, with the Least Significant Bit (LSB) issued first. Each data byte is conveyed as mark/space information with two marks comprising the stop data. When the last byte of data is transmitted, a hold comprises one steady mark (the last stop bit). To begin or resume data transfer, a space (00h) substitutes this mark.

Remote Operations QAM256 Digital Video Modulator and Upconverter and recognizes that the message is a duplicate, so the associated commands within the packet are not executed a second time. However, the response packet is again sent back to the source, as an acknowledgment in order to preclude undesired multiple executions of the same command. To reiterate, valid equipment responses to a message require the FSN tag in the command packet. This serves as part of the handshake/acknowledge routine.
QAM256 Digital Video Modulator and Upconverter Remote Operations C.1.5 Collision Avoidance When properly implemented, the physical and logical devices and ID addressing scheme of the COMMSPEC normally precludes message packet contention on the control bus. The importance of designating unique IDs for each device during station configuration cannot be overemphasized. One pitfall, which is often overlooked, concerns multi-drop override IDs.
Remote Operations QAM256 Digital Video Modulator and Upconverter advantageous to consider the use of multiple bus systems where warranted by a moderate to large equipment complement. Therefore, if a DMD15 Modulator is queried for its equipment type identifier, it will return a "20" and DMD15 Demodulator will return a "21". A DMD15 Modem will also return a "22". A DM45 Video Modulator will return a “23.” C.1.
QAM256 Digital Video Modulator and Upconverter Remote Operations If the RLLT receives the packetized message from the sender before it times out, it checks for any error messages appended by the IOPT. In the absence of errors, the RLLT processes the received command sent via the transmitted packet and issues a "message out" system call to ultimately acknowledge the received packet. This call generates the response packet conveyed to the sender.
