Installation

2.0 Installation Requirements

The DD240XR can be installed within any standard 19-inch equipment cabinet or rack, and
requires one rack unit (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 of the DD240
is designed to have power enter from the left and IF cabling enter from the right when viewed from
the rear of the unit. Data and control cabling can enter from either side although they are closer to
the center. The unit can be placed on a table or suitable surface if required.

There are no user-serviceable parts or configuration settings located inside
the DD240XR
power supply module. DO NOT open the DD240XR
circumstances.

Before initially applying power to the unit, it is a good idea to disconnect
the transmit output from the operating ground station equipment. This is
especially true if the current DD240XR configuration settings are unknown,
where incorrect setting could disrupt exis ting communications traffic.

Earth connection is essential before connecting power to the DD240XR due
to high leakage curr ent.

Installation DD240XR High-Speed Digital Demodulator

2.1 Unpacking

The DD240XR Demodulator was carefully packaged to avoid damage and should arrive complete
with the following items for proper installation:

 DD240XR Unit
 PCMCIA Card (May be installed, depending upon configuration. If no card is

installed, the unit has been factory configured)

 Power Cord, 6 foot with Applicable AC Connector
 Installation and Operation Manual.

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 DD240XR modulator is shipped fully assembled. It does not require removal of the covers for
any purpose in installation. The only replaceable assembly in the unit is the data interface and is
not intended to be accomplished in the field. If the AC power connector is the wrong type for the
installation, either the cable or the power connector should be replaced. The power supply itself is
designed for universal application using from 100 to 240 VAC, 50 to 60 Hz, < 40 W.

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 DD240XR 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.

Do not mount the DD240XR in an unprotected outdoor location where there is direct contact with
rain, snow, wind or sun. The DD240XR is designed for indoor applications only.

The only tools required for rack mounting the DD240XR
an appropriate screwdriver. Rack mount brackets are an integral part of the cast front bezel of the
unit and are not removable.

Shielded cables with the shield terminated to the conductive back shells are required in order to
meet EMC directives. Cables with insulation flammability ratings of 94 VO or better are required
in order to meet low voltage directives.

Earth connection is essential before connecting power to the DD240XR due to High Leakage
Current.

DD240XR High-Speed Digital Demodulator Installation

2.4 Demodulator Checkout

The following descriptions assume that the DD240XR is installed in a suitable location with prime
AC power and supporting equipment available.

2.4.1 Initial Power-Up

Before initial power up of the DD240XR, it is a good idea to disconnect
the transmit output from the operating ground station equipment. This is
especially true if the current demodulator configuration settings are
unknown, where incorrect setting could disrupt existing communications
traffic. New units from the factory are normally shipped in a default
configuration which includes setting the transmit carrier off.

Turn the unit ‘ON’ by placing the rear panel switch (above the power entry connector) to the ‘ON’
position. Upon initial and subsequent power-ups, the DD240XR microprocessor will test itself and
several of its components before beginning its main Monitor/Control program. These power-up
diagnostics show no results if successful. If a failure is detected, the Fault LED is illuminated.

The initial field checkout of the DD240XR can be accomplished from the Front Panel, Terminal
Port, Remote Port, or Ethernet Port.

DD240XR High-Speed Digital Demodulator Operation

Theory of Operation

3.0 Theory of Operation

The basic theory of operation for each platform is similar. The DD240XR is capable of supporting
L-band from 950-2150 MHz and can be upgraded to include IF frequencies of 50-180 MHz in the
same package. If the unit is configured to receive analog signal in the IF band of 50-180 MHz, the
signal is converted to L-band. The L-band signal is then tuned and digitally demodulated. The
incoming I&Q symbols are then filtered decoded, and mapped to data bits. The network
specification selected will determine if the data stream supports DVB-S or DVB-S2 formats.

The DVB-S Network specification complies with both EN300-421 and EN301-210 ETSI
specifications. EN300-421 supports QPSK demodulation and EN301-210 supports higher
demodulation rates of 8PSK and 16QAM. The resulting data stream is FEC decoded by the
Viterbi (K=7) inner convolutional/trellis decoder, de-interleaved and further FEC decoded by the
outer Reed Solomon 204/188 decoder.

The DVB-S2 Network specification complies with the next generation DVB open standard
supported by EN302-307. At the core of this standard is a powerful Bose-Chaudhuri­Hocquenghem BCH decoding and concatenated Low-Density Parity Check (LDPC). The
DD240XR only supports normative features identified by the DVB-S2 Broadcast services. The
Broadcast Services mode of operation supports Constant Coding and modulation (CCM) system
and single transport streams. Operating in this mode allow for a variety of FEC rates to be used
with QPSK, 8PSK and 16APSK modulation schemes.

The decoded data is then sent through a deframer to provide terrestrial data that is either
unframed, 188 byte DVB format or 204 byte DVB format. Based on the type of terrestrial interface
installed, the data stream is re-clocked through an optional Doppler buffer, serialized and
converted through the appropriate physical layer interface. A functional block diagram is shown in
Figure 3-1.

Used to enable pilot symbol for DVB-S2 only

GOLD SEQ N: {012345}
Gold code sequence number for DVB-S2 only

LAST RATE CTRL: {SYMBOL RATE, DATA RATE, AUTO}

Indicates the rate (symbol or data) which is maintained

when associated parameters (i.e. Modulation, Inner FEC
Code Rate, Terr Framing) are changed. For example, if
the Last Rate Control is set to “Symbol Rate” and the
modulation is subsequently changed, the system will
attempt to maintain the same symbol rate by adjusting
the data rate. If the Last Rate Control is set to “Data
Rate” and the modulation is subsequently changed, the
system will attempt to maintain the same data rate by
adjusting the symbol rate.

4-6 MN-DD240XR – Rev. E

DD240XR High-Speed Digital Demodulator User Interfaces

The “Auto” Setting of Last Rate Control causes the last
explicitly changed rate (symbol or data) to be maintained
when associated parameters are changed. For
example, if the last rate control is set to “Auto” and the
Data Rate is subsequently explicitly changed, any
subsequent changes to Modulation or Inner FEC Rate
would cause the symbol rate to be adjusted in order to
maintain the Data Rate.

ACQ RANGE: {Variable in one Hz steps}
Acquisition Range – Allows the user to set the carrier

acquisition sweep range. Sweep rate range changes
based on Data rate and FEC rate.

LNB POWER: {ON, OFF}
Used to enable the LNB 18V DC Output to J6.

TERR ETHERNET: This menu is displayed when Ethernet interface is

installed. This interface supports MPEG over IP traffic.
This menu can be configured to support Ethernet Bridge
option or PRO MPEG COP3 option. Each option
supports different menu structures. The following items
are available under the Terrestrial Ethernet menu:

PROG ETH FLASH: {PRESS CLEAR}

When Bridge option is selected, the PROG ETH FLASH
menu is the only menu displayed. The PROG ETH

MPEG packets with the following contents:

 Sync byte (0x47)
 Second byte that increments once per MPEG

packet

 186 data bytes that are a running counter that

increments each byte across all MPEG packets

The Ethernet Data Interface will lock to this stream as
though it were actual demodulated data and generate the
appropriate UDP, RTP, and FEC packets depending up
the operational mode.

4.3 Host Computer Remote Communic ations

Control and status messages are conveyed between the DD240 and the subsidiary modems and
the host computer using packetized message blocks in accordance with a proprietary
communications specification. This communication is handled by the Radyne Link Level Protocol
(RLLP), which serves as a protocol ‘wrapper’ for the RM&C data.

Complete information on monitor and control software is contained in the following sections.

4.3.1 Protocol Structure

The Communications Specification (COMMSPEC) defines the interaction of computer resident
Monitor and Control software used in satellite earth station equipment such as modems,
redundancy switches, multiplexers, and other ancillary support gear. Communication is bi­directional, and is normally established on one or more full-duplex 9600-baud multi-drop control
buses that conform to EIA Standard RS-485.

Each piece of earth station equipment on a control bus has a unique physical address, which is
assigned during station setup/configuration or prior to shipment. Valid decimal addresses on one
control bus range from 032 through 255 for a total of up to 224 devices per bus. Address 255 of
each control bus is usually reserved for the M&C computer.

4.3.2 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 one 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. This handling scheme is controlled
by the hardware and is transparent to the user. A pictorial representation of the data and its
surrounding overhead may be shown as follows:

4-28 MN-DD240XR – Rev. E

DD240XR High-Speed Digital Demodulator User Interfaces

S1

ST

The stop bit S1 is a mark. Data flow remains in a hold mode until the start bit ST is replaced by a
space. The start bit (ST) is not part of the actual data (B

The above byte-oriented protocol is standard for UART based serial communication ports such as
Workstation or Personal Computer (PC) COM ports. COM ports should be configured for 8 data
bits, no parity, and one stop bit. For example, for 9600-baud operation, COM ports should be
configured as:

The COMMSPEC developed for use with the Radyne Link Level Protocol (RLLP) organizes the
actual monitor and control data within a shell, or "protocol wrapper", which surrounds the data.
The format and structure of the COMMSPEC message exchanges are described herein. Decimal
numbers have no suffix; hexadecimal numbers end with a lower case h suffix and binary values
have a lower case b suffix. Thus, 22 = 16h = 000010110b. The principal elements of a data
frame, in order of occurrence, are summarized as follows:

<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 509. This field is 2 bytes long for the DD240 protocol.
<SOURCE ID> - the Source Identifier defines the multi-drop address origin. Note that all nodes
on a given control bus have a unique address that must be defined.

<DESTINATION ID> - The Destination Identifier serves as a pointer to the multi-drop destination
device that indicates where the message is to be sent.

<FRAME SEQUENCE NUMBER> - The FSN is a tag with a value from 0 through 255 that is sent
with each message. It assures sequential information framing and correct equipment
acknowledgment and data transfers.

<OPCODE> - The Operation Code field contains a number that identifies the message type
associated with the data that follows it. Equipment under MCS control recognizes this field
firmware identification and subsequently steers the DATA accordingly to perform a specific
function or series of functions. Acknowledgment and error codes are returned in this field. This
field is 2 Bytes for the DD240 protocol.

<...DATA...> - The Data field contains the binary, bi-directional data bytes associated with the
<OPCODE>. The number of data bytes in this field is indicated by the <BYTE COUNT> value.

<CHECKSUM> - The checksum is the module 256 sum of all preceding message bytes,
excluding the <SYN> character. The checksum determines the presence or absence of errors
within the message. In a message block with the following parameters, the checksum is
computed as shown below in Table 4-1.

<DESTINATION ID> 2Ah = 00101010b 00011100b

<FSN> 09h = 00001001b 00100101b
<OPCODE> (Byte 1) 00h = 00000000b 00100101b
<OPCODE> (Byte 2) 03h = 00000011b 00101000b

<DATA> (Byte 1) DFh = 11011111b 00000111b
<DATA> (Byte 2) FEh = 11111110b 00000101b

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.

Since the only concern is the modulo 256 (modulo 100h) equivalent (values that can be
represented by a single 8-bit byte), the checksum is 05h.

For a decimal checksum calculation, the equivalent values for each information field are:

0 + 2 + 240 + 42 + 9 + 0 + 3 + 223 + 254 = 773;
773/256 = 3 with a remainder of 5. This remainder is the checksum for the frame.
5 (decimal) = 05h = 0101b = <CHECKSUM>

4.3.3 Frame Description and Bus Handshaking

In a Monitor and Control environment, every message frame on a control bus port executes as a
packet in a loop beginning with a wait-for-SYN-character mode. The remaining message format
header information is then loaded, either by the M&C computer or by a subordinate piece of
equipment requesting access to the bus. Data is processed in 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. If the OPCODE resides within a
command message, it defines the class of action that denotes an instruction that is specific to the
device type, and is a prefix to the DATA field if data is required. If the OPCODE resides within a
query message packet, then it defines the query code, and can serve as a prefix to query code
DATA.

The Frame Sequence Number (FSN) is included in every message packet, and increments
sequentially. When the M & C computer or bus-linked equipment initiates a message, it assigns
the FSN as a tag for error control and handshaking. A different FSN is produced for each new
message from the FSN originator to a specific device on the control bus. If a command packet is
sent and not received at its intended destination, then an appropriate response message is not
received by the packet originator. The original command packet is then re-transmitted with the
same FSN. If the repeated message is received correctly at this point, it is considered a new
message and is executed and acknowledged as such.

If the command packet is received at its intended destination but the response message
(acknowledgment) is lost, then the message originator (usually the M&C computer) re-transmits
the original command packet with the same FSN. The destination device detects the same FSN
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.

4-30 MN-DD240XR – Rev. E

DD240XR High-Speed Digital Demodulator User Interfaces

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. If a valid response message
is absent, then the command is re-transmitted with the same FSN. For a repeat of the same
command involving iterative processes (such as increasing or decreasing transmit power level),
the FSN is incremented after each message packet. When the FSN value reaches 255, it
overflows and begins again at zero. The FSN tag is a powerful tool that assures sequential
information framing, and is especially useful where commands require more than one message
packet.

The full handshake/acknowledgment involves a reversal of source and destination ID codes in the
next message frame, followed by a response code in the <OPCODE> field of the message packet
from the equipment under control.

If a command packet is sent and not received at its intended destination, a timeout condition can
occur because a response message is not received by the packet originator. On receiving
devices slaved to an M & C computer, the timeout delay parameters may be programmed into the
equipment in accordance with site requirements by Radyne Corporation prior to shipment, or
altered by qualified personnel. The FSN handshake routines must account for timeout delays and
be able to introduce them as well.

4.3.4 Global Response Operational Codes

In acknowledgment 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.
The device that receives the valid message then exchanges the <SOURCE ID> with the
<DESTINATION ID>, sets the <OPCODE> to zero in order to indicate that a good message was
received, and returns the packet to the originator. This "GOOD MESSAGE" Opcode is one of
three global responses.

If a bad parameter or inconsistent value is sent in an RLLP Message, the reply packet will have an
operational code value of 00FFh and the unit will log an event. The operator should inspect the
event log to determine the reason for a message failure.

Table 4-2. Response OPCODES

RESPONSE OPCODE DESCRIPTION OPCODE

Good Message 000d = 0000h
Bad Parameter 255d = 00FFh

Bad Opcode 254d = 00FEh

4.3.5 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. All too often, multiple
devices of the same type are assigned in a direct-linked ("single-thread") configuration accessible
to the M&C computer directly. For example, if two DD240 Demodulators with different addresses
(DESTINATION IDs) are linked to the same control bus at the same hierarchical level, both will
attempt to respond to the M&C computer when the computer generates a multi-drop override ID
of 23. If their actual setup parameters, status, or internal timing differs, they will both attempt to

MN-DD240XR – Rev. E 4-31

User Interfaces DD240XR High-Speed Digital Demodulator

respond to the override simultaneously with different information, or asynchronously in their
respective message packets and response packets, causing a collision on the serial control bus.

To preclude control bus data contention, different IDs must always be assigned to the equipment.
If two or more devices are configured for direct-linked operation, then the M&C computer and all
other devices configured in the same manner must be programmed to inhibit broadcast of the
corresponding multi-drop override ID.

The multi-drop override ID is always accepted by devices of the same type on a common control
bus, independent of the actual DESTINATION ID. These Override IDs with the exception of
“BROADCAST” are responded to by all directly linked devices of the same type causing
contention on the bus. The “BROADCAST” ID, on the other hand, is accepted by all equipment
but none of them returns a response packet to the remote M&C.

The following multi-drop override IDs are device-type specific, with the exception of
"BROADCAST". These are summarized below with ID values expressed in decimal notation:

Note that 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
Corporation 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 run­time software. It is also 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 DVB3030
Video Modulator will return a “23.”

4.3.6 Software Compatibility

The COMMSPEC, operating in conjunction within the RLLP shell, provides for full forward and
backward software compatibility independent of the software version in use. New features are
appended to the end of the DATA field without OPCODE changes. Older software simply
discards the data as extraneous information without functional impairment for backward
compatibility.

If new device-resident or M&C software receives a message related to an old software
version, new information and processes are not damaged or affected by the omission of data.

The implementation of forward and backward software compatibility often, but not always,
requires the addition of new Opcodes. Each new function requires a new Opcode assignment if
forward and backward compatibility cannot be attained by other means.

When Radyne Corporation 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.

When new features are added to Radyne Corporation equipment, the control parameters are
appended to the end of the non-volatile section, and status of the features, if any, are added at the
end of the volatile section. If a remote M&C queries two pieces of Radyne Corporation equipment
with different revision software, they may respond with two different sized packets. The remote
M&C MUST make use of the non-volatile count value to index to the start of the volatile section. If
the remote M&C is not aware of the newly added features to the Radyne Corporation product, it
should disregard the parameters at the end of the non-volatile section and index to the start of the
volatile section.

If packets are handled in this fashion, there will also be backward-compatibility between Radyne
Corporation equipment and M&C systems. Remote M&C systems need not be modified every
time a feature is added unless the user needs access to that feature.

4.3.7 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.
Each transmitted packet is subject to ‘time out’ and ‘frame sequence’ control parameters, after
which the packet sender waits for the receiver to convey its response. Once a receiver verifies
that a packet sent to it is in the correct sequence relative to the previously received packet, it
computes a local checksum on all information within the packet excluding the <SYN> character
and the <CHECKSUM> fields. If this checksum matches the packet <CHECKSUM>, the receiver
processes the packet and responds to the packet sender with a valid response (acknowledgment)
packet. If the checksum values do not match, the receiver replies with a negative
acknowledgment (NAK) in its response frame.

The response packet is therefore either an acknowledgment that the message was received
correctly, or some form of a packetized NAK frame. If the sender receives a valid
acknowledgment (response) packet from the receiver, the <FSN> increments and the next packet
is transmitted as required by the sender. However, if a NAK response packet is returned the
sender re-transmits the original information packet with the same embedded <FSN>.

MN-DD240XR – Rev. E 4-33

User Interfaces DD240XR High-Speed Digital Demodulator

If an acknowledgment (response) packet or a NAK packet is lost, corrupted, or not issued due to
an error and is thereby not returned to the sender, the sender re-transmits the original information
packet; but with the same <FSN>. When the intended receiver detects a duplicate packet, the
packet is acknowledged with a response packet and internally discarded to preclude undesired
repetitive executions. If the M&C computer sends a command packet and the corresponding
response packet is lost due to a system or internal error, the computer times out and re-transmits

4.3.8 Remote Port Packet Structure

The RLLP Remote Port Packet structure is as follows:
<SYNC>: Message format header character that defines the

beginning of a message. The <SYNC> character value

is always 0x16. (1 byte).
<BYTE COUNT>: Number of bytes in the <DATA> field. (2 bytes).
<SOURCE ID>: Identifies the address of the equipment from where the

message originated. (1 byte).
<DEST. ID>: Identifies the address of the equipment where the

message is to be sent. (1 byte).
<FSN>: Frame sequence number ensures correct packet

acknowledgment and data transfers. (1 byte).
<OPCODE>: This field identifies the message type associated with the

information data. The equipment processes the data

according to the value in this field. Return error codes

and acknowledgment are also included in this field. (2

bytes).
<...DATA...>: Information data. The number of data bytes in this field is

indicated by the <BYTE COUNT> value.
<CHECKSUM>: The modulo 256 sum of all preceding message bytes

excluding the <SYNC> character. (1 byte).

4.3.9 DD240XR Opcode Command Set

The data rate and symbol rate values must be range checked when altering: Data Rate, Symbol
Rate, Inner FEC, Modulation Type, or Framing. Use the following formulas for range checking:

Max Symbol Rate >= Symbol Rate = (Data Rate * Overhead) / (Code Rate * Modulation)
Max Data Rate >= Data Rate = (Symbol Rate * Code Rate * Modulation) / Overhead

Overhead 204/188 when framing is set to 188 bytes.
204/204 when framing is set to 204 bytes.
204/187 when framing is set to none.

Modulation 16QAM = 4
8PSK = 3
QPSK = 2

Code Rate 1/2, 2/3, 5/6, 3/4, 7/8, 8/9
Also, if an interface is being used which does not have buffering capability the buffer size may

only be set to 0 milliseconds.
Other restrictions, rules or formatting are described in the front panel or SNMP MIB portions of the

equipment manual.
The DD240 Opcode Command Set is listed below.
