  • Page 26: Redundancy Systems

    Overview Redundancy systems The Codan Redundancy Controller 6586 is used to control two BUCs and two LNBs (when used) in a redundancy system. When a detectable fault occurs in the on-line BUC, and the off-line BUC is serviceable, the redundancy controller switches over the two BUCs.

  • Page 27: The Redundancy Controller

    Overview Redundancy system control You can control and monitor the redundancy switching equipment: • locally, using a Hand-held Controller 6560 connected to the BUC 1 Serial/BUC 2 Serial connectors on the redundancy controller • remotely, using the optional Remote Controller 6570 connected to the Auxiliary I/O connector on the redundancy controller The redundancy controller...

  • Page 29: Figure 10: Connector Panel On The Redundancy Controller

    Overview Switches The control panel of the redundancy controller has one switch. The function of this switch is to select the AC input voltage (115 or 230 V AC). Connectors The connector panel is located at the bottom of the redundancy controller.

  • Page 30: How The Redundancy Controller Works

    Overview How the redundancy controller works When you power up the system, the redundancy controller uses the current status of the BUC Switch and LNB Switch (when used) to select the on-line stream. If the redundancy controller detects that the NOTE switches are inconsistent, or cannot be detected, it selects Stream 1.
  • Page 31 Overview BUC faults The redundancy controller uses a PLD to monitor the alarm signals from both BUCs. The BUCs send alarm signals via cables connected to the 14-way BUC 1 Control and BUC 2 Control connectors on the redundancy controller. Red BUC 1/BUC 2 LEDs on the control panel of the redundancy controller indicate that there is a fault with the corresponding BUC or LNB.
  • Page 32 Overview Auxiliary I/O interface of the redundancy controller The Auxiliary I/O interface of the redundancy controller enables you to perform the following functions remotely: • monitor operation of the redundancy switching system using the isolated relay contacts • switch streams using external signals Most of the remote control functions are achieved by grounding the appropriate control signal to 0 V.

  • Page 33: Rf Waveguide Switches

    Overview RF waveguide switches RF waveguide switches control both the receive and transmit RF paths. The switches direct signals for both on-line and off- line BUCs and LNBs (when used). Transmit/receive C-Band systems may use either two RF waveguide switches or one combined RF waveguide/coaxial switch.
  • Page 34 Overview Systems using a combined RF waveguide/coaxial switch (C-Band only) In the receive path, a receive RF waveguide switch directs the received RF from the receive port of the antenna feed to one of the LNBs. In the transmit path, an RF coaxial switch directs the transmitted RF from the on-line BUC to the transmit port of the antenna feed.
  • Page 35 Overview Systems using a single transmit RF waveguide switch (transmit-only) In the transmit path, a single transmit RF waveguide switch directs the transmitted RF from the on-line BUC to the transmit port of the antenna feed. The RF from the off-line BUC is directed into an appropriately-rated termination.

  • Page 36: The Remote Controller 6570 And Hand-Held Controller 6560

    Overview The Remote Controller 6570 and Hand-held Controller 6560 The Remote Controller 6570 provides remote control and monitoring facilities of the BUCs at a convenient indoor location. The remote controller is connected via its BUC Interface connector to the Auxiliary I/O connector on the redundancy controller using the cable supplied.

    Installation Table 8: Pinouts of the AC INPUT connector (Amphenol T 3110 000) Description Neutral Not connected Active Protective earth It is recommended that BUCs are installed as close as possible to the antenna feed to minimise losses. Heavier BUCs may need to be mounted further CAUTION down the boom to minimise the mechanical leverage load on the antenna.

  • Page 42: Cable Recommendations

    Installation Cable recommendations Table 9 lists the recommended specifications for IF coaxial cables used in your system. These specifications place restrictions on the maximum length of the transmit IF cable. The limiting factor is most likely the 20 dB maximum cable loss.

  • Page 43: Cable Lengths

    Installation DC loop resistance specification The maximum DC loop resistance is determined by the DC power drawn by a BUC and its minimum operating input voltage. Some BUCs are not powered via the cable, so the DC loop resistance of the IF cable is not a consideration for such BUC installations.

  • Page 44: If Levels

    Installation IF levels The figures and tables in this section show the single carrier IF levels required to achieve rated P1dB output power from the BUC using various types and lengths of IF cables.
