DVB3030/DVB3030L Digital Video Broadcast Modulator Installation Section 2 – Installation 2.0 Installation Requirements The DVB3030/DVB3030L can be installed within any standard 19-inch equipment cabinet or rack, and requires 1 RU mounting space (1.75 inches) vertically and 17 inches of depth. Including cabling, a minimum of 20-inches of rack depth is required. The rear panel is designed to have power enter from the left and IF cabling enter from the right when viewed from the rear of the unit.
Installation DVB3030/DVB3030L Digital Video Broadcast Modulator 2.3 Mounting Considerations When mounted in an equipment rack, adequate ventilation must be provided. The ambient temperature in the rack should be between 10° and 35° C, and held constant for best equipment operation. The air available to the rack should be clean and relatively dry. The DVB3030 units may be stacked one on top of the other up to a maximum of 10 consecutive units before providing a 1 RU space for airflow.
DVB3030/DVB3030L Digital Video Broadcast Modulator TM052 - Rev. 3.
DVB3030/DVB3030L Digital Video Broadcast Modulator Operation Section 3 – Operation 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.
Operation DVB3030/DVB3030L Digital Video Broadcast Modulator If Symbol mode is selected, the operation of the modem should be very similar to other Radyne products. If the Symbol Rate is entered, the Data Rate is calculated from the newly entered Symbol Rate, the Framing mode, the QAM mode and the Convolutional mode. If the Data Rate is entered, then the Symbol Rate is calculated instead. If the Framing mode, the QAM mode or the Convolutional mode is entered, the Data Rate is recalculated.
DVB3030/DVB3030L Digital Video Broadcast Modulator User Interfaces Section 4 – User Interfaces 4.0 User Interfaces There are four user interfaces available for the DVB3030. These are: a. b. c. d.

DVB3030/DVB3030L Digital Video Broadcast Modulator User Interfaces 4.3 Remote Port User Interface The Remote Port of the DVB3030 allows for complete control and monitor functions via an RS-485 Serial Interface. Control and status messages are conveyed between the DVB3030 and the subsidiary modems and the host computer using packetized message blocks in accordance with a proprietary communications specification.
User Interfaces DVB3030/DVB3030L Digital Video Broadcast Modulator - the Source Identifier defines the multi-drop address origin. Note that all nodes on a given control bus have an unique address that must be defined. - The Destination Identifier serves as a pointer to the multi-drop destination device that indicates where the message is to be sent. - The FSN is a tag with a value from 0 through 255 that is sent with each message.
DVB3030/DVB3030L Digital Video Broadcast Modulator User Interfaces 5 (decimal) = 05h = 0101b = 4.3.3 Flow Control and Task Processing The original packet sender (the M&C computer) relies on accurate timeout information with regard to each piece of equipment under its control. This provides for efficient bus communication without unnecessary handshake overhead timing. One critical value is designated the Inter-Frame Space (FS).
User Interfaces DVB3030/DVB3030L Digital Video Broadcast Modulator accordance with the OPCODE, and the checksum for the frame is calculated. If the anticipated checksum does not match then a checksum error response is returned to the message frame originator. The entire message frame is discarded and the wait-for-SYN mode goes back into effect.

User Interfaces DVB3030/DVB3030L Digital Video Broadcast Modulator When Radyne equipment is queried for information (Query Mod, Query Demod, etc.) it responds by sending back two blocks of data; a non-volatile section (parameters that can be modified by the user) and a volatile section (status information). It also returns a count value that indicates how large the non-volatile section is. This count is used by M&C developers to index into the start of the volatile section.

DVB3030/DVB3030L Digital Video Broadcast Modulator Maintenance Section 6 – Maintenance 6.0 Periodic Maintenance The DVB3030 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 DVB3030. If this does not cure the problem, wiring or power should be suspect. There is no external fuse on the DVB3030.
