Comtech EF Data's Proprietary "Daisy Chain" configuration distributes the converter protection switching functions in the converters.

  • Page 56: Backup Converter

    A.2.2 D ETACHABLE ODULES Comtech EF Data's converters are designed with a detachable Input/Output Module (IOM) which contain the signal path connectors. The IOM is utilized for single thread operation, or for testing of the unit. For redundant "Daisy Chain" operations, the on-line up converters are provided with a detachable Transmit Switch Module (TSM) replacing the IOM.

    UT4500 Series Up Converter MN/UT4500.IOM Remote Control Rev. 0 A.4.2 A UTOMATIC ONFIGURATION ERIFICATION The backup converter has a menu that allows the operator to choose, on a converter-by- converter basis, manual (M) or automatic (A) operating mode. Figure 29 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 MN/UT4500.IOM Remote Control Rev. 0 A.4.4 O FFSET DJUSTMENT 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.
  • Page 69 UT4500 Series Up Converter MN/UT4500.IOM Remote Control Rev. 0 To remove a “Backup” converter for repair the following procedure must be used: Turn the power switch on the backup converter rear panel to OFF, and remove the power cord from the converter.
