Introduction

1.0 Description

The Radyne OMS11 Outdoor Modem Switch provides redundancy protection for the OM20 Outdoor Modem, BUC and LNB. The OMS11 offers redundancy support for OM20 user data, Asynchronous data, RS485 and BUC/LNB Waveguide Switching control. The OMS11 redundancy system is based on a Chain switching system that switches the IF/RF primary path to the IF/RF Backup path. Optional BUCs, LNBs, Waveguide Switches and Mounting hardware are optional items that can be supplied with the system. Contact Radyne for supported hardware options. Refer to Figure 1-1 for an illustration of the OMS11 1:1 Redundancy Switch Front Panel and Figure 1-3 of an OMS11 Functional Block Diagram.

Operating in the Automatic Mode, the OMS11 immediately places a Backup Modem and IF/RF Path online in the event of a Primary Modem/IF/RF path fails. The OMS11 chain switches the modem, BUC and LNB. In the Manual Mode, the user may designate the selected Online Primary Modem from either the Interactive Front Panel or a remote Terminal Interface. The backup functions of the OMS11 may be performed manually via the front panel or the RS485, RLLP remote protocol or the RS232 Terminal port.

Figure 1-1 OMS11 1:1 Redundancy Switch Front Panel

1.1 Redundant Power Supplies

The OMS11 is equipped with two fully redundant internal power supplies. Each power supply is independent of the other, including their source of AC or DC input source. The OMS11 remains fully operational as long as either power supply is providing a source of power. The power supplies are internal to the OMS11 Chassis.

Theory of Operation

2.0 Theory of Operation

The Radyne OMS11 Outdoor Modem Switch provides redundancy protection for the OM20 Outdoor Modem, BUC and LNB. The OMS11 redundancy system is based on a Chain switching system that switches the IF/RF primary path to the IF/RF Backup path. The Chain Switching system can includes BUCs, LNBs, Waveguide, Waveguides Switches, mounting hardware and connecting cables. BUCs, LNBs, Waveguide Switches and Mounting hardware are optional items that can be supplied with the system. Refer to Figure 1-1 for an illustration of the OMS11 1:1 Redundancy Switch Front Panel and Figure 2-1 for the OMS11 Functional Block Diagram.

The BUC and LNB switch over fault detection system is primarily done by the OM20 Modem. When the OM20 is configured to supply power to the BUC and LNB, the modem uses internal detection circuitry to monitor current and voltage status of the BUC and LNB. User must properly set up the BUC/LNB voltage and current threshold limits on the OM20. Refer to the OM20 user manual for proper set.

In cases where the BUCs are powered by an external power supply, fault detection can be detected by the OM20 only if the BUC includes Normally Closed contact closures. In order to support BUC redundancy, the BUC must have Normally Closed Contact closures available for the OMS11/OM20 to support redundancy.

2.1 OMS11 Operation

A block diagram of the signal flow is shown in Figure 2-1 below.

Figure 2-1 Functional Block Diagram

TM133 – Rev. 1.1

Theory of Operation OMS11 1:1 Redundancy Switch

2-2

2.1.1 Operating Procedures

The OMS11 is designed to require minimal operator intervention and control during normal operation. After initial setup, the unit should operate in a relatively ‘transparent’ manner, providing trouble-free backup of the online Modems. The scope of this section is limited to instruction on the various modes of control available to the operator. Refer to Section 3-1 for the OMS11 Front Panel Controls and Indicators and Table 2-1 for a description of the Controls and Indicators.

2.1.2 Configuring the OMS11

The redundancy switch must be properly configured prior to operation. Date interface type, Remote communication type and remote baud rate must be set correctly to meet the users needs. Configuring these options can only be done by removing the cover and accessing the dip switches on the board. Appendix A of this manual gives specific information about the dip switch settings for configuring the Terminal and Remote ports. If you need assistance with the settings, contact Radyne customer service department.

2.1.3 Front Panel Controls (Refer to Figure 2-1)

The purpose of the ‘ENABLE’ pushbutton on the front panel is to reduce the risk of accidentally changing the operating modes of the OMS11 by accidentally bumping any one of the front panel pushbuttons. For any one of the front panel pushbuttons to function, the ‘ENABLE’ pushbutton must be depressed simultaneously with the desired function pushbutton. Depress the ‘ENABLE’ pushbutton. This pushbutton must be depressed to allow the operator to proceed with any other configurations. The ‘MANUAL’ LED should illuminate and the FAULT indicator may momentarily flash. Under the MOD region of the front panel, depress ‘SELECT A’ to bring Modem ‘A’ modulator online. The green LED should illuminate. Under the DEMOD region of the front panel, depress ‘SELECT A’ to bring modem ‘A’ demodulator online. The Green LED should illuminate. The OMS11 should now be in backup mode with modem ‘A’ online.

2.1.4 Manual Mode

To manually select which Modem is to be placed online, simultaneously depress the ‘ENABLE’ pushbutton and the appropriate Modem ‘SELECT’ pushbutton. When a Modem select ion is made, the OMS11 enters Manual Mode to carry out the selection, and will not respond to either modem’s Modem Fault signals until placed back into Auto Mode.

2.1.5 Auto Mode

To enable automatic backup in the event of a Modem failure, the OMS11 must be placed into the Auto Mode. First, select which Modem that will be active by following the ‘Manual Mode’ procedure in the previous paragrap h. To enter the Auto Mode, simultaneously depress the ‘ENABLE’ pushbutton and the ‘SELECT AUTO’ pushbutton. The OMS11 will then enter into Auto Mode with the last selections made in Manual Mode. In the Auto Mode, the decision to switch from one Modem to another is made automatically by monitoring the Fault signals from each modem.

2.1.6 Power-Up Defaults

During power-Up, the OMS11 initiali ze s its elf to the last mode set by the operator on the front panel pushbuttons.

TM133 – Rev. 1.1

OMS11 1:1 Redundancy Switch Theory of Operation

2.2 OMS11 Major Assemblies

The OMS11 Redundancy Control Unit contains the modules that control and monitor the operation of the 1:1 Switch system. The 1:1 Switch is composed of the followin g major assemblies and components:

Main Switch Board Waveguide Switch Board Front Panel Dual (Redundant) Po wer Supplies

2.2.1 Main Switch Board

The Main Switch Board contains the OMS11 1:1 Switch Intelligenc e and Memory Circuitry and all switching circuitry. The microprocessor controls and coordinates all of the major functions of the Switch and performs all necessary calculations. The non-volatile system memory on the board stores the switching parameter settings for each modem channel. Control and data signals are routed to the appropriate devices in the system through various latches and transceivers that are controlled by the microprocessor.

2.2.2 Front Panel

The Front Panel contains the LED Indicators and the pushbutton switches needed to control and operate the OMS11. Refer to Figure 3.0 for a description of Front Panel Indicators.

2.2.3 Redundant Power Supplies

The 1:1 Switch comes equipped with two fully redundant internal power supplies (PS1 and PS2) that supplies power to the switch and external switching components. Each supply is fully independent of the other, including their source of AC/DC power and fusing. The Switch can remain fully operational as long as it is supplied with a source of voltage from either power supply.

2.3 OMS11 General Operation

2.3.1 Data Signals

Modem data signals are backed-up through a passive switching system. Signals that are required to maintain the modem in off-line (hot-standby) are buffered by appropriate circuitry to minimize loading on incoming signals.

2.3.2 Backup

If an online Modem fault is sensed, and the off-line Modem is in a non-faulted state, the OMS11 will switch to the Modem without the fault. The Fault Signal has a small debounce delay to prevent false triggering. If the faulted Modem has its fault cleared, it stays off-line unless the other MODEM has subsequently faulted.

2.3.3 Fail-Safe

If the OMS11 has a non-recoverable internal fault, the swit c h w il l revert back to Modem A, the Switch Fault LED is illuminated, and the Switch Fault Relay switches to a faulted state.

TM133 – Rev. 1.1

Theory of Operation OMS11 1:1 Redundancy Switch

2-4

If Power Supply 1 and Power Supply 2 simultaneously fail, the switching circuitry in the OMS11 reverts back to Modem A, and the Switch Fault Relay switches to a faulted state. Modem B does not receive buffered signals in this condition.

2.3.4 OMS11 Fault Relays

The OMS11 M&C Connector (J8) has Form-C contacts available that indicate modem online and OMS11 Fault status. Refer to section for additional information.

2.4 Fault Detection

The OMS11 & OM20 work simultaneously to determine the status of all the componen ts within this system. The OMS11 & OM20 are capable of monitoring BUC and LNB redundancy system. Faults detection is established by the OM20 and forwarded to the OMS11. Fault detection for a redundant BUC system will be different based on whether the BUC Power is supplied by the OM20 or if the BUC Power is supplied by an external power source. If the BUC power is supplied externally, then the BUC must have Normally Closed Form C Fault contacts so the OMS11/OM20 can monitor the BUC fault status.

Fault detection with the OM20 supplying power to BUC:

• BUC Faults - OM20 uses internal fault detection circuitry to determine BUC status and initiates a fault that is forwarded to the OMS11

• OM20 uses internal fault detection circuitry to determine LNB status and initiate fault

Fault detection with BUC power supplied externally:

• BUC must have Normally Closed Form C contacts in order for BUC fault detection to

work

• OM20 data cable CAR5902 or CAR5918 has an external connector that is used to

connect and monitor Form C Contacts from the BUC.

• OM20 uses internal fault detection circuitry to determine LNB status and initiate fault

Installation

4.0 Installation Requirements

The diagrams in this section display the OMS11 and OM20s mounted on the Antenna King Post as shown in figure 4-1 an d 4-2. The cables supplied in the base system are based on this layout utilizing the mounting kit supplied by Radyne.

There are no user-serviceable parts located inside the OMS11 Chassis. There is a potential shock haz ard internally at the power supply module. DO NOT open the OMS11 Chassis under any circumstance s.

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 curr ent OMS11 configuration settings are unknown, where incorrect setting could disrupt existing communications traffic.

The OMS11 is shipped with protective covers over the connectors. The protective covers are used to create a moisture tight seal. Protective covers must remain on the unit if connector is not used.

4.1 Unpacking

The OMS11 was carefully packaged to avoid damage and should arrive complete with the following items for proper installation:

4.1.1 Test Data Sheet

Each OMS11 1:1 Redundancy Switch system is shipped with a Test Data Sheet. This report contains information on the results of the Switch quality control testing. The report also includes information pertaining to the system settings that were made at the factory. Radyne recommends that the user save this report for future reference.

4.2 Site Considerations

Adequate site planning and preparation simplifies the installation process and results in a more reliable system. The user should ensure that the site has adequate electrical power, environmental controls and protection against sources of electrical radiation and interference.

4.2.1 Power Sources

The power sources should be properly grounded and as free as possible from electrical interference. The OMS11 employs a dual redundant power supply configuration. Each power connection on the OMS11 must be plugged into its own separate power circuit. Each circuit must have its own independent circuit breaker.

Grounding is achieved automatically when the properly terminated power connector is inserted into the power receptacle. This should be checked by testing that there is no voltage present between the chassis of the Switch and the power line ground.

The protective ground must not be bypassed or defeated In any way. Defeating the ground may result in operator Injury or damage to the system.

5.2.1 AC Power Input (J6, J10)

AC Inputs are located on connector J6 and J10 of the OMS11. The auto-ranging univer sa l power supply input allows for the connection of AC power to the port between the range of 100 – 240 VAC and 50 – 60 Hz. Power consumption for the unit is 1.0A (OMS11) only. An external chassis ground post is located on the OMS11. The ground post is a #10-32 threaded stud that is used for external grounding and should not be used to ground the AC power Source on J6 and J10. The mating power connector is a 4-pin socket MFG P/N (D38999/24FC4SN) connecter. The mating connector supplied with the unit.

Refer to Table 5-3 AC Po w erfor the connector pinouts.

Table 5-3 AC Pow er

5.3 Ground Lug

An external chassis ground post is located on the OMS11, which requires a #10-32 threaded stud.

5.4 Remote Monitor & Control (J8)

This port functions as the OMS11 Remote and Fault port utilizing an 18-Pin D38999/24FD18PN Connector. The Remote Port located on J8 allows for control and monitoring of parameters and functions via an RS-232 Serial Interface or RS-485 for RLLP Protocol. ‘Equipment remote setup parameters can be configured via the main board or Terminal mode. Based on the user's application, this may require the user to set the Remote Port, properly configuring the units for Multidrop Address followed by setting the Remote Interface from RS232 to RS485.

The mating connector is supplied with the unit. Refer to Table 5-5 for the Remote/Terminal

connector pinouts. The OMS11’s internal M&C system is connected to most of the circuitry on any board contained

in the chassis. These connections provide status on the condition of the circuitry and provide the data required for the various measurements the OMS11 provides. The on-board M&C proc ess es this information and generates status indications and alarms when necessary. Status information is available via the Remote port and the Form-C fault connections available on this connector. This summary information can be connected to external equipment or alarms. Refer to Table 5-3.

5.4.1 Terminal Mode (RS232)

The Terminal Mode has the advantage of providing full screen access to the switches parameters, but requires a separate terminal or computer running a Terminal Program. No external software is required other than VT-100 Terminal Emulation Sof tware (e.g. “Procomm” for a computer when used as a terminal. The Control Port is normally used as an RS–232

TM133 – Rev. 1.1

Connector Pinouts OMS11 1:1 Redundancy Switch

5-4

Connection to the terminal device. This is the standard configuration when shipped from factory. Refer to Table 5-5for pinouts. Refer to Appendix A for configuring unit to RS232 Terminal.

The factory terminal setup is as follows:

Emulation Type: VT-100 (can be changed) Baud Rate: 9600 Data Bits: 8 Parity: No Parity (Fixed) Stop Bits: 1 Stop Bit

The factory terminal Baud Rate can be changed by accessing dip switches located on the main board. Internal DIP switches are accessible only by removing the top cover. Refer to Appendix A, Figure A2.

5.4.2 Modem Remote Communications (RLLP/RS485)

The RLLP Remote Port is located on J8 allows for control and monitoring of parameters and functions via an RS-485. Control and status messages are conveyed between the modem and all 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. Refer to Table 5-5 for pinout descriptions. Refer to Appendix A for configuring the unit to RS485 Remote. Refer to Appendix B for the RLLP Protocol.

This requires the user to first properly setup the unit ensuring Multidrop Address are configured as needed. The OMS11 has internal DIP switches that are accessible only by removing the top cover. DIP switch S3 is used to configure remote baud rates and addressing. Refer to Appendix A, Figure A2 for dip switch information. If you are having trouble with DIP switch settings, contact Radyne Customer Service for any additional help.

5.4.3 Common Equipment Faults (J8)

Common equipment fault hardware is available on the OMS11. The OMS11 M&C Connector (J8) has Form-C contacts available that indicate which modem is online and indicates OMS11 Fault status. Refer to Table 5-5.

5.4.3.1 Fault Detection

The OMS11 & OM20 work simultaneously to determine the status of all the components within this system. The OMS11 & OM20 are capable of monitoring BUC and LNB redundancy system. Faults detection is established by the OM20 and forwarded to the OMS11. Fault detection for a redundant BUC system will be different based on whether the BUC Power is supplied by the OM20 or if the BUC Power is supplied by an external power source. If the BUC power is supplied externally, then the BUC must have Normally Closed Form C Fault contacts so the OMS11/OM20 can monitor the BUC fault status.

Figure 5-2 reflects the BUC fault detection connector which is required for BUC that are using external Power supplies.

Fault detection with the OM20 supplying power to BUC:

• BUC Faults - OM20 uses internal fault detection circuitry to determine BUC status and initiates a fault that is forwarded to the OMS11

• OM20 uses internal fault detection circuitry to determine LNB status and initiate fault

Fault detection with BUC power supplied externally:

• BUC must have Form C contacts in order for BUC fault detection to work

• OM20 data cable CAR5902 or CAR5918 has an external connector that is used to

connect and monitor Form C Contacts from the BUC.

• OM20 uses internal fault detection circuitry to determine LNB status and initiate fault

Maintenance and Troubleshooting

6.0 Basic Troubleshooting and Maintenance

This section provides information on the basic troubleshooting and repair procedures for the OMS11 1:1 Switch that may be performed on-site by qualified personnel. Only minor repairs will be discussed. For serious failures, the user should not attempt to repair the unit without first contacting the Radyne Customer Service Department at 602-437-9620 for further information and instructions.

6.1 Basic User Checks

Upon the detection of an operational failure, the source of the failure must be determined. Basic user checks include checking the various cables and connectors.

6.1.1 Checking the Cabling and Connectors

Problems that appear difficult to solve can often be traced to a loose or defective cable or connector. The user should first verify the following:

• All cables within the system have no broken or loose connections. Cables that are suspect should be replaced.

• All jacks on the units have no bent or broken pins.

• Both AC Power Cords are properly plugged into the rear of the OMS11.

6.2 Major and Minor Faults

Major faults are failure conditions or combinations of conditions that result in loss of service on one or more channels. Minor faults are failure conditions that do not result in loss of service.

Possible Major Fault conditions are:

A Read-Only Memory (ROM) failure in the Switch; A Random Access Memory (RAM) failure in the Switch; A loss of Carrier Detect on a Demodulator Channel where this attribute is monitored; A loss of Terrestrial Input Clock on a Channel where this attribute is monitored; A failure of two monitored Modulators; A failure of two monitored Demodulators; A failure of both OMS11 power supplies.

Possible Minor Fault conditions are as follows:

A failure of one of the Switch’s two redundant power supplies; A failure of one Demodulator that is being monitored (i.e., a Demodulator that has not

been locked out);

A failure of one Modulator that is being monitored; A reference clock slip.

OMS11 Rem ot e Comm unications

B.0 Host Computer Remote Communications

Control and status messages are conveyed between the OMS11 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 Radyne RLLP Protocol Reference Guide.

For RS485 Remote communication, install CA/3733 gender changer into the remote port. Gender changes port from RS232 to RS485

B.0.1 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.

B.0.2 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. 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:

S1 S2  B

 B1  B2  B3  B4  B5  B6  B7  S1  S2, etc.

TM133 – Rev. 1.1 B-1

Appendix B OMS11 1:1 Redundancy Switch

The stop bits, S1 and S2, are each a mark. Data flow remains in a hold mode until S2 is replaced by a space. If S2 is followed by a space, it is considered a start bit for the data byte and not part of the actual data (B

- B 7).

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.

<DATA COUNT> - the 2 Byte Data Count is the number of bytes in the <DATA> field, ranging from 0 through 509.

<SOURCE ID> - the Source Identifier defines the multi-drop address origin. Note that all nodes on a given control bus has an 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 O through 255 that is sent with each message. It assures sequential information framing and correct equipment acknowledgment and data transfers.

<OPCODE> - the 2 Byte Operation Code field contains a number that identifies the message type associated with the data that follows it. Equipment under MCS control recognizes this byte via 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. 1 Byte for the DMD5000 protocol and 2 Bytes for the DMD15 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 modulo 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 in Table 1.

BYTE FIELD DATA CONTENT

RUNNING CHECKSUM

<BYTE COUNT> 02h = 00000000b 00000000b <BYTE COUNT> 02h = 00000010b 00000010b <SOURCEID> F0h = 11110000b 11110010b <DESTINATION ID> 2Ah = 00101010b 00011100b <FSN> 09h = 00001001b 00100101b <OPCODE> 03h = 00000011b 00101000b <DATA> (Byte 1) DFh = 11011111b 00000111b <DATA> (Byte 2) FEh = 11111110b 00000101b

Table 1. Checksum Calculation Example Thus, the checksum is 00000101b; which is 05h or 5 decimal. Alternative methods of calculating

the checksum for the same message frame are:

B-2 TM133 – Rev. 1.1

OMS11 1:1 Redundancy Switch Appendix B

02h + FOh + 2Ah + 09h + 03h + DFh + FEh = 305h. Since the only concern is the modulo 256 (modulo 1 00h) 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 + 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> ]

B.0.3 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 (such as the DMD15) 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 which 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 incr em ents 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.

To reiterate, valid equipment responses to a message require the FSN tag in the command packet. These serve 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 the transmit power level of a DMD15 modulator), 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.

TM133 – Rev. 1.1 B-3

Appendix B OMS11 1:1 Redundancy Switch

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 Corp. 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.

B-4 TM133 – Rev. 1.1

OMS11 1:1 Redundancy Switch Appendix B

B.0.4 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. The device that receives the valid m es sage then exc hang es the <SOURCE ID> with the <DESTINATION ID>, sets the <OPCO D E> 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 nine global responses. Global response opcodes are common responses, issued to the M&C computer or to another device that can originate from and are interpreted by all Radyne equipment in the same manner. These are summarized as follows (all opcode values are expressed in decimal form):

RESPONSE OPCODE DESCRIPTION OPCODE Good Message 000

Bad Parameter 255 Bad Opcode 254 Bad Checksum 253 Command Not Allowed in LOCAL Mod e 252 Command Not Allowed in AUTO Mode 251 Bad Destination 250 Unable to Process Command 249 Packet Too Long 248

Table 2. Response OPCODES

B.0.5 Software Compatibility

The DMD15 RLLP is not software-compatible with the following previous Radyne

products: RCU5000 and DMD4500. These products may not occupy the same bus

while using this protocol as equipment malfunction and loss of data may occur.

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.

TM133 – Rev. 1.1 B-5

Appendix B OMS11 1:1 Redundancy Switch

B.0.6 RLLP Summary

The RLLP is a simple send-and-wait protocol that automatically re-transmits a packet whenever 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>.

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 the same command packet with the same <FSN> to the same receiver and waits once again for an acknowledgment or a NAK packet.

To reiterate, the format of the message block is shown in below in Table 3, Link Level Protocol Message Block.

SYNC COUNT SRC ADDR DEST ADDR FSN OP CODE DATA BYTES CHECKSUM

Table 3. Link Level Protocol Message Block

B.1 Remote Port Packet Structure:

The OMS11 protocol is an enhanc ement on the DMD5000 protocol. It also uses a packet structure format. The 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) <F.S.N.> = Frame sequence number insures correct packet acknowledgment and data transfers. (1 byte)

B-6 TM133 – Rev. 1.1

OMS11 1:1 Redundancy Switch Appendix B

≈

<OPCODE> = This byte 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)

The DMD15 RLLP is not software-compatible with the following previous Radyne

products: RCU5000 and DMD4500. These products may not occupy the same bus

while using this protocol as equ ipment malfunction and loss of data may occur.

When transmitting a packet at 9600 baud, the Remote M&C should ensure

that the timeout value between characters does not exceed the time it takes to transmit

200 characters (

200 msec). If this timeout value is exceeded, the equipment will

timeout.
