    SONNEL. 2.1 HARDWARE INSTALLATION The following discussion makes frequent reference to Fig 2.1 The NV3128 installs in a 19-inch EIA equipment rack. No fans or cooling are required, but adequate free air space should be maintained around the equipment. 1. Using the 2MM allen key supplied, remove the doors and vanity ear covers from the front of the frames.
  • Page 28 All manuals and user guides at all-guides.com 8. Connect the AC line cord at the rear of the frame and to the input AC, which powers up the NV3128. Ensure the system powers up correctly. a. LEDs on the Power Supply front panel should glow.

  • Page 30: Configuration

    The Command Interpreter and the Matrix Control II are obsolete control cards for the NV3128 Router. Some instructions in this section apply only to older systems having these cards. These instructions have been retained for the benefit of customers who own older systems, but they are labeled "(OBSOLETE)"...
  • Page 31 All manuals and user guides at all-guides.com PARTITION DIP SWITCHES (OBSOLETE) 1. Two banks of dip switches on the Control Interface Module configure the partition information for the NV3128. Bank 1 defines the physical partition, Bank 2 enables the ghost partition and defines its controller level.
  • Page 32 00001 = level 1 where 0 denotes an OFF bit and 1 denotes an ON bit. 10001 = level 17. The range is from 0-31. Some control protocols define levels alphabetically, in which case 0=A and 25=Z. NV3128 RS-422A Machine-Control Routing Switch...
  • Page 33 The length of the partition is the number in the switch times 32. For the NV3128, the number is 0100 (128). For a 64 port version of the switch, the number is 0010. No other configuration is valid for a data switch.
  • Page 34 2.2.4 CONFIGURING THE SERIAL INTERFACE (OBSOLETE) 2.2.4.1 JUMPER SETTINGS (OBSOLETE) The serial data interface between the control system and the NV3128 can be either RS-422A or RS-232. For the newer Universal Control module, the serial interface ports are set up using UniDiag. For the older Command Interpreter, jumpers on the Command Interface Module select parameters appropriate to the chosen protocol.
  • Page 35 All manuals and user guides at all-guides.com 2.2.5 PARALLEL INTERFACE (OBSOLETE) Newer NV3128 frames do not include a parallel interface. The older NV3128 frames with the Command Interpreter card included a parallel connector which could be used with the Pesa parallel interface. Because the Universal Control card does not support the parallel interface, older frames that have the Universal Control card cannot make use of the parallel interface connector.

    4.2 CIRCUIT OPERATION The following discussion provides an overview of circuit operation for each of the circuit boards in the NV3128 Router frame. Because repair is done by replacing modules rather than repairing them, schematics and bills of material are not provided but may be requested from NVISION Technical Support.
  • Page 68 I/O modules by 16 octal buffer/line-driver integrated circuits. MISC: A submodule and associated circuitry process raw DC from the power supply to produce a carefully regulated and current limited +5VDC for distribution across the module. NV3128 RS-422A Machine-Control Data Routing Switch...
  • Page 69 Submodules each operate separately on the raw DC input voltage to provide +5VDC operating levels for 1/2 the available circuits. By thus dividing the circuitry, the impact block of a failure is correspondingly reduced. NV3128 RS-422A Machine-Control Data Routing Switch...
  • Page 70 Further, the assembly contains all circuitry required to configure the NV3128, and produces master timing signals for the system. MAPPING At the heart of the module are the microprocessors that govern circuit operation.
  • Page 71 NV3128, this oscillator free runs. PARTITIONING On the Command Interpreter two banks of DIP switches and their associated circuitry configure the NV3128 into partitions. Additionally, software versions supporting various controllers may make use of these switches for supplementary configuration control.

  • Page 73 A boot-strap multivibrator circuit on the submodule initializes the power-supply circuitry. Although each of the NV3128 modules has its own on-board voltage regulators and current limiters, the power supply itself is self limiting. Transformer T2 monitors the primary current and steps it down to a level where it can safely drive the PWM submodule, shutting it down completely in case of excessive load.

    Technical Support at the front of this manual. 5.2 SCHEDULED MAINTENANCE The NV3128 requires no periodic maintenance. It is recommended to check the front panel LEDs on each of the cards periodically to ensure that they are operating properly.

  • Page 78: Troubleshooting

    All manuals and user guides at all-guides.com 5.4 TROUBLESHOOTING Certain features of the NV3128 facilitate troubleshooting the router. · Power supplies and all active modules can be removed and re-inserted live without damage. · Since mapping of the crosspoint modules takes place continuously, a crosspoint card removed and re-inserted will be updated within a few cycles of video vertical retrace.
