  • Page 39: Chapter 4. Redundant Configuration

    The MBT-4000 is designed to operate in both stand-alone and redundant configurations. Every MBT-4000 base contains the circuitry and logic necessary to perform all the functions of a backup controller in either a single base and dual base configuration. The BDC-4000 is capable of supplying LNA power over the center conductor of the coaxial cable.

  • Page 40: Single-Base Redundancy Operation

    SINGLE MBT-4000 REDUNDANT SWITCH Figure 4-1. Single-Base Redundancy Operation The MBT-4000 base unit monitors health of the two BDCs or two BUCs installed. In case of a fault on the on-line BxC, the MBT-4000 base will automatically switch over to the standby BxC according to the following rules: 1.

  • Page 41: Dual-Base (Chain) Redundancy Operation

    DUAL MBT-4000 REDUNDANT SWITCH Figure 4-2. Dual Base (Chain) Redundancy Operation The two MBT-4000 base units cooperate in monitoring the health of the four BxCs (and each other). In case of a fault on an on-line BxC the MBT-4000 base containing the corresponding standby BxC, will automatically switch over to the standby BxC according to the following rules: 1.

  • Page 42: External Fault Monitoring

    The MBT-4000 base and BDC-4000 are capable of supplying power to external LNAs. The MBT-4000 base supplies the power from a pin in the AUX COMM connectors. The BDC- 4000 supplies the power over the center conductor of the coaxial cable.

  • Page 43: Gain Equalization Of Redundant Units

    If a current is detected outside this window, a LNA current fault will be posted, but the supply will not be disabled. Gain Equalization of Redundant Units Gain equalization in an MBT-4000 system is accomplished by issuing individual attenuation settings to the specific BxCs. Operational Configuration Commands In automatic redundancy mode, configuration commands (with the exception of attenuation and LNA power supply configuration) sent to the on-line unit will be mirrored in the off-line unit.

    Multi-Band Transceiver System Revision 3 Redundant Configuration MN/MBT4000.IOM LED Status Indicators The two LED indicators reflect the staus of the MBT-4000 as follows: For the Online status: GREEN No faults present and the unit is unmated. YELLOW No faults present and the unit is muted.

  • Page 45: Appendix A. Remote Control

    Appendix A. Remote Control This section describes the protocol and message command set for remote monitor and control of the BUC/BDC-4000 product. The electrical interface is either an RS-485 multi-drop bus (for the control of many devices) or an RS-232 connection (for the control of a single device), and data is transmitted in asynchronous serial form, using ASCII characters.
  • Page 46 Multi-Band Transceiver System Revision 3 Remote Command MN/MBT4000.IOM RS-485 (full duplex) summary: Two differential pairs one pair for controller to target one pair for target to controller Controller-to-target pair one line driver (controller) and all targets have line- receivers. Target-to-controller pair one line receiver (controller) and all targets have tri- state drivers.
  • Page 47 The BDC and BUC sub-devices may also be addressed by appending the corresponding sub- device address. The sub-device address is ‘A1’ for the BUC and ‘A2’ for the BDC. For example, a mute command addressed to a BUC attached to an MBT-4000 at address 0412 will be: <0412A1/MUT=1{CR}...
  • Page 48 Multi-Band Transceiver System Revision 3 Remote Command MN/MBT4000.IOM The format of the response will be: >0412A1/MUT={CR}{LF} Sub-device addresses cannot be changed. The controller sends a packet with the address of a target - the destination of the packet. When the target responds, the address used is the same address, to indicate to the controller the source of the packet.
  • Page 49 Multi-Band Transceiver System Revision 3 Remote Command MN/MBT4000.IOM From Target-to-Controller, the only permitted values are: = (ASCII code 61) ? (ASCII code 63) (ASCII code 33) (ASCII code 42) (ASCII code 35) They have these meanings: The ‘=’ code (target to controller) is used in two ways: First, if the controller has sent a query code to a target (for example MUT?, meaning ‘is mute enable or disable?’), then the target would respond with MUT=x, where x represents the state in question, 1 being ‘enable’...
