Page 14: Section 2 - Installation
DM240-DVB High-Speed Digital Modulator Installation Installation This section provides unpacking and installation instructions, and a description of external connections and backward alarm information. 2.0 Installation Requirements The DM240 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.
Page 15: Unpacking
Installation DM240-DVB High-Speed Digital Modulator 2.1 Unpacking The DM240 Modulator was carefully packaged to avoid damage and should arrive complete with the following items for proper installation: DM240 Unit. PCMCIA Card. May be installed, depending upon configuration. If no card is installed, the unit has been factory configured.
Page 16: Initial Power-Up
DM240-DVB High-Speed Digital Modulator Installation 2.4.1 Initial Power-Up Before initial power up of the DM240, it is a good idea to disconnect the transmit output from the operating ground station equipment. This is especially true if the current modulator configuration settings are unknown, where incorrect setting could disrupt existing communications traffic.

DM240-DVB High-Speed Digital Modulator User Interfaces 4.9 Remote Port User Interface The Remote Port of the DM240 allows for complete control and monitor functions via an RS-485 Serial Interface. Control and status messages are conveyed between the DM240 and the subsidiary modems, and the host computer using packetized message blocks in accordance with a proprietary communications specification.
Page 37 User Interfaces DM240-DVB High-Speed Digital Modulator <SYN> - the message format header character, or ASCII sync character, that defines the beginning of a message. The <SYN> character value is always 16h. <BYTE COUNT> - the Byte Count is the number of bytes in the <DATA> field, ranging from 0 through TBD.
Page 38: Frame Description And Bus Handshaking
DM240-DVB High-Speed Digital Modulator User Interfaces Thus, the checksum is 00000101b; which is 05h or 5 decimal. Alternative methods of calculating the checksum for the same message frame are: 00h + 02h + F0h + 2Ah + 09h + 00h + 03h + DFh + FEh = 305h.
Page 39: Global Response Operational Codes
User Interfaces DM240-DVB High-Speed Digital Modulator 4.9.4 Global Response Operational Codes In acknowledgment (response) packets, the operational code <OPCODE> field of the message packet is set to 0 by the receiving devices when the message intended for the device is evaluated as valid.
Page 40: Collision Avoidance
DM240-DVB High-Speed Digital Modulator User Interfaces 4.9.5 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.
Page 41: Software Compatibility
User Interfaces DM240-DVB High-Speed Digital Modulator Multi-drop override ID 01 can be used interchangeably to broadcast a message to a DMD-3000/4000 modem, a DMD-4500/5000, a DMD15 modem, or a DVB3030. Radyne Corp. recommends that the multi-drop override IDs be issued only during system configuration as a bus test tool by experienced programmers, and that they not be included in run-time software.
Page 42: Rllp Summary
DM240-DVB High-Speed Digital Modulator User Interfaces 4.9.7 RLLP Summary The RLLP is a simple send-and-wait protocol that automatically re-transmits a packet when an error is detected, or when an acknowledgment (response) packet is absent. During transmission, the protocol wrapper surrounds the actual data to form information packets.
