Chapter 4. Redundant System Operation 4.1 OVERVIEW The Comtech EF Data UT-4500 Series Up Converters are configured for redundant system operation using distributed protection switching in an active "Daisy Chain" configuration. Comtech EF Data's Proprietary "Daisy Chain" configuration distributes the converter protection switching functions in the converters. This provides a system capability to backup from 1 to 12 online converters.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 4.2 BACKUP CONVERTER The "Daisy Chain" terminates in the backup converter. The backup converter has a microprocessor which performs fault detection, self reconfiguration and the logical switching functions. If the backup converter does not have a fault, it will assume the frequency and attenuation of the faulted converter and compensate for the chain losses.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 4.3 REDUNDANT CONFIGURATIONS Comtech EF Data UT-4500 Series Up Converters can be configured in several different redundant subsystem "Daisy Chain" configurations to meet the reliability requirements of a communication system. These configurations include: Table 13.

UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 4.4 REDUNDANT SYSTEM CONFIGURATION 4.4.1 INITIAL CONFIGURATION Redundant system configuration is controlled from the converter’s front panel configuration menu. Each online unit is assigned a redundancy configuration address. This address is dependent on the location of the online converter with reference to the backup. The unit closest to the backup must be converter # 1. The next unit down must be converter # 2.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 4.4.2 AUTOMATIC CONFIGURATION VERIFICATION The backup converter has a menu that allows the operator to choose, on a converter-byconverter basis, manual (M) or automatic (A) operating mode. Figure 30 shows the system configured for automatic (A) operation. In this mode, failure of an online converter will automatically cause a switchover to the redundant unit to occur.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 Figure 31 depicts the front panel displays after power has been turned off on converter #1. Note the on line LED is illuminated on the backup converter. This indicates that the backup is now providing the frequency translation in place of the online unit. As soon as power is restored, converter #1 will come back online. STATUS POWER ON ON LINE TRANSMIT FAULT REMOTE STORED FAULT CONV-01-OFFSET=+00.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 4.4.3 MANUAL CONFIGURATION/VERIFICATION Figure 32 shows the system with converter #1 configured for manual (M) operation. In this mode, the backup converter can force switchover of an online unit. This mode also overrides fault status detection of the online units performed by the backup converter. If an online unit is configured to manual mode and this unit faults, no switchover will occur.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 Figure 33 shows the front panel displays after the backup has forced converter 1 offline. Note the online LED allows the user to tell whether the backup is currently active and which converter is being by passed. STATUS POWER ON ON LINE TRANSMIT FAULT REMOTE STORED FAULT CONV-01-OFFSET=+00.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 4.4.4 OFFSET ADJUSTMENT The offset is used to compensate for cable and switch losses. When the system is initially set up and tested, each converter needs to be forced to backup and the offset adjusted to minimize gain mismatch between the normal and bypassed mode. This offset will be different for each converter and is stored in a table in the backup unit.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 To remove a “Backup” converter for repair the following procedure must be used: 1 Turn the power switch on the backup converter rear panel to OFF, and remove the power cord from the converter. Disconnect the RF and IF cables from the IOM Module. 2 Unscrew the rack mounting screws on the front panel of the backup converter. 3 Remove the backup converter from the front of the rack.

Chapter 5. Remote Control 5.1 GENERAL Each Comtech EF Data series Up Converter can be remotely controlled through a serial port. Primary (chained) converters in a redundancy subsystem can also be indirectly controlled through the backup converter using virtual addressing. Comtech EF Data’s simplified Command/Response protocol is easily invoked by either a monitor and control computer, a non-intelligent ASCII terminal or a laptop computer operating in terminal emulation mode.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 5.2.2 BAUD RATE The default serial port Baud Rate is 9600. Baud rates of 1200, 2400, 4800, 19200, and 38400 are also supported. 5.2.3 FORMAT The following parameters are the default character format. 1 Start Bit 8 Data Bits No Parity Bit 1 Stop Bit 5.2.4 CHARACTER SET The character set implemented is ASCII. 5.2.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 5.3 ACCESS METHODS Converters may be accessed directly by using a physical address or indirectly through a backup converter by using a virtual address. 5.3.1 DIRECT ACCESS Converters may be directly accessed by the EIA-232 interface or by the EIA-485 interface in a bus configuration. 5.3.1.1 EIA-485 In this control network, all converters including the backup converter are paralleled on a common EIA-485 cable.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 5.3.2.2 EIA-232 To control by using the EIA-232 interface, one EIA-232 port on the monitor and control computer is required for each backup converter. Virtual addressing must be established by command. All converters including the backup converter must be in the Redundancy Mode. 5.4 ADDRESSES All converters are addressed in a command by the Device Address.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 5.5 MESSAGE STRUCTURE The structure of either a Command , Response or Error Message is as follows: Start Character. Device Address. Command or Response. End of Message String. 5.5.1 START CHARACTER The Start Character begins each message: Example: < Start of a user Command. > Start of a converter response. 5.5.2 DEVICE ADDRESS The Device Address consists of a Physical Address or a Physical Address and an appended Virtual Address.
UT4500 Series Up Converter Remote Control MN/UT4500.IOM Revision 2 5.5.5 ERROR RESPONSE If a converter cannot execute a Command or detects a protocol violation, an error response is generated. An error is flagged by changing the "/" command designator in the response to a "?". Following the "?" error symbol are two characters which are unique error symbols useful for computer analysis. The two error symbols are followed by a text string explaining the error for the convenience of a human operator.

Chapter 6. Theory of Operation 6.1 APPLICATIONS This appendix contains a general description of the theory of operation for the Model UT-4500 Series Up Converters. The UT-4500 Series Up Converters are used for SCPC, DAMA AND TDMA, as well as for full transponder HDTV and analog TV, applications. The converter operates over the RF frequency range with a typical gain of 35 dB.
UT4500 Series Up Converter Theory of Operation MN/UT4500.IOM Revision 2 The "Daisy Chain" configuration is designed to chain the IF input and RF output of up to twelve (12) on-line converters together through TSM's terminating in a backup converter. When a fault occurs in an on-line converter, the TSM in the converter with the fault is commanded to switch to the backup converter. The backup converter performs the fault detection, self reconfiguration and the logical switching functions.

UT4500 Series Up Converter Maintenance and Troubleshooting MN/UT4500.IOM Revision 2 7.2.2 TROUBLESHOOTING Converter operating problems can be identified by first observing the status indicators on the front panel. When a fault condition is indicated, the specific fault, or faults, can be identified in the Figure 18, which is accessed through the local operation keypad and displayed on the LCD display located on the front panel. The status of converter functions is displayed in the Figure 17.
UT4500 Series Up Converter Maintenance and Troubleshooting MN/UT4500.IOM Revision 2 7.2.3.3 RF CONVERTER MODULE IFLO LOCK DETECT: A fault (“FT”) indicates that the IFLO is not locked. Check all connections to the converter module to make sure they are secure. If the fault still exists, remove the Converter Module and return it to Comtech EF Data for repair. 7.2.3.4 SYNTHESIZER SUM LOOP MODULE SUM LOOP DETECT: A fault (“FT”) indicates that the sum loop is not locked.
UT4500 Series Up Converter Maintenance and Troubleshooting MN/UT4500.IOM Revision 2 7.2.4 CONVERTER I/O MODULES The Converter I/O Modules (IOM, or TSM) are installed on the rear panel of the converter. The screws holding the I/O Module to the converter chassis are installed “hand tight”. When installing an I/O Module “DO NOT” use a screwdriver to tighten the module mounting screws - install screws “hand tight” only. IMPORTANT 7.
