The PLURA Rubidium series GI-module is a "Master Time Code"-generator with most typical studio synchronization possibilities with various dynamic amount of in-/output formats.

The GI a self-contained IRIG-B generator, designed for compact applications, which require only one power supply and one GPS receiver. 

The GI offers extensive monitoring and controlling possibilities and was designed for complex and fail-proof redundant systems.

     GI IN/OUT

    GI Inserter

    The GI includes a set of universal interfaces enabling it to be implemented into smaller compact Time Code applications as well as larger multigenerator studio system applications. It can interface with wide range of output signals.
    The following interfaces and connections are available:            

    • IRIG-B-generator, Reference
    • LTC-reader, VTR
    • Serial interface, Reference GPS/DCF
    • Input seconds pulses
    • Input Primary- identifier
    • Output DCF-Telegram
    • DC input, Battery buffered clock unit
    • GPI In-/Output
    • Option: LTC- or IRIG-B reader, Reference
    • Option: Clock driver output

    The rear-sided RLC plug carries voltage supply, a fault detector relay and a TC_link signal. The TC_link is a real time capable proprietary interface, which is based on a RS485 interface and a PLURA user specific protocol. The second external interface present on the housing is the USB PC interface.  All data transfers, such as data exchange between the modules, configuration of the module, status monitoring and software updates are completed via the “TC_link” or the “PC” interface.
    Software updates are available for the modules firmware, its browser or for the programmable digital hardware components of the modules. The latest software and firmware updates are available on our web site or by request via email.

    Modules can be inserted in any order into the available slots of a housing. Each slot position has its own address within the  communal address of the systems housing identification  address. This enables each module to be specifically identified within a bigger system. To simplify the location and identification of a module, alias names can be given to the hard stamped numerical address via the supplied configuration software. When any RUB module is inserted into any of our housings, each module is automatically connected to an internal “hot swappable” bus. This internal bus bilaterally connects all modules within that particular housing and can also be connected to other housings & modules via a RLC-plug  located on the rear of all our housing models.

    Via our IE Ethernet module, browser configuration, status control and SNMP functions are available.

    Four programmable front keys allow for quick functional changes or loading preset profiles. Backlit buttons and four further status LEDs signal the module’s operating condition. A blue button clearly states the module’s identification. (RUBIDIUM Series1 only)

    IRIG-B usually is synchronized (locked) to a reference. Various GPS or DCF protocols (e.g. NMEA or Meinberg) can be used as a time reference for generated Time Code. Other optional time reference signals include IRIG-B, LTC, or NTP signals. A temperature compensated precision quartz is used to enable an extremely stable free-running time source in case of a signal loss. A battery-backed circuit for the generation of the reference time along with an external reference (e.g. GPS) ensures a stable operation.

    The GPS receiver and the internal time reference quartz can externally be supplied with power via a separate plug (even when the main housing is turned off), in order to ensure a constant reference that is ready for use immediately after powering up a system. 

    IRIG-B Time Code is widely known as a dependable reference signal. The GI's generator was designed in accordance with all of the IRIG-B standards. Via the standard internal interface connection, all system data can be transferred to any other module in a connected system (TC_link).

    PLURA also offer a series of different signal amplifier modules for the distribution of all GI signals, some of which offer failsafe circuitry. 

    Because of the large amount of interfaces, upgradable software, programmable hardware and the assortment of other combinable modules, there is almost infinite amount of possible applications. We suggest breaking down your requirements into needed inputs and  outputs. The RUBIDIUM config software allows for an easy overview of all available functions of the desired module.

    GI Configuration
    GI Configuration 2

    The DRVSEL input signal determines the primary or secondary  operation mode of the GI in a fail safe system. Time Code and status data are made available for monitoring the system (e.g. read-in  and read-out times, synchronization status and operational data).
    All status data can be queried and monitored by serial interface or TC_link. In combination with an IE ethernet module, NTP and SNMP funtionalities are available as well.
    GI Monitoring

    The various universal input and output interfaces allow for a multitude of options, such as user programmable offset times. There are many customer specific applications possible, so please don’t hesitate to ask us for suggested solutions for your projects.
    The PLURA GI module is a compact master Time Code  system. Due to its large amount of serial interfaces, all substantial periphery can directly be integrated (e.g. time displays, PCs and reference inputs). Various signal amplifiers, inserters and an Ethernet interface (NTP, SNMP, Browser) are optionally available by simply adding the applicable module to the interconnected system.

     GI Fail Safe

    A redundant master Time Code system consists of two GPS receivers, two master Time Code generators and a monitoring signal switcher.
    The SI-module is responsible for monitoring and switching the IRIG-B, the SR- module is reponsible for the reference signals (e.g. GPS).
    With two connected power supply modules or an additional external supply of 24V a redundant electrical supply can be ensured.
    NTP and SNMP are available with the addition of IE Ethernet module, where a parallel ope-ration of two or more IE modules allows for automatic redundancy.
