\B E D I E N E L E M E N T E >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> INTRODUCTION Thank you very much for purchasing iCLOCK or iCLOCK dp, Redundant Multiple Clock Synthesizer & Video Reference Generator, from MUTEC! About this Manual The whole manual is related to both versions in general, iCLOCK and iCLOCK dp. The individual differences are mentioned in the according sections and chapters.
INTRODUCTION \\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Differences between Software V2.10 and V2.11 Both versions include the preset management as new functionality, which was inquired by several professonal MUTEC customers (see page 28). Using software V2.10 or V2.11 depends on the alarm interface you have already installed or you plan to install. Software V2.10 supports only the older interface iC-ALARM (ordering no. 8005-056), whereas software V2.
\B E D I E N E L E M E N T E >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CONTROL elements iCLOCK + iCLOCK dp Front Panel iCLOCK and iCLOCK dp front panels look equal 1 2 1 Display All parameter and function settings are controlled using the display and the four cursor buttons. 3 4 Refer to the OPERATIONS chapter for more information. 2 + 3 STATUS Indicators The three blue indicators show the lock status of the currently active clock source.
CONTROL ELEMENTS \\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 5 PAL/NTSC VIDEO OUT SD bi-level PAL and NTSC composite video sync signals are sent from these outputs. After installing the optional P/NVSG-02 video sync generator (item no. 8010-010), a separate video format can be assigned to each output pair. Associated output pairs are arranged on top of each other.
\B E D I E N E L E M E N T E >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> INSTALLATION Content of the Box The unit was packed carefully. Nevertheless we recommend to check the content directly after opening the package: ! Before Powering Up 1 x iCLOCK / iCLOCK dp 1 x Power cable, 2 x power cables for iCLOCK dp 4 x Rubber feet 1 x Manual 1 x Registration card The condition of the packaging material and the device should be checked carefully additionally.
I N S TALLAT I O N \\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Wiring the AES/EBU and S/P-DIF interfaces ! Cables for High Clock Rates Especially when working with high AES3/-11 clock rates well shielded clock lines are imperative to avoid increased radiation! Standard cables are nor-mally useable for clock rates up to 50.0kHz. Special shielded cable material should be used for transfer of higher clock rates.
\B E D I E N E L E M E N T E >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> GENERAL OPERATION Menu Structure The entire menu structure is based on the logical flow of events when deploying the iCLOCK in a standard audio/video-studio environment. Therefore, starting with the menu main page, the menu pages have an ergonomically structured sequence and can thus be called successively by repeatedly pressing the up button.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Selecting Menu Pages and setting Functions ! Safety Instructions For safety reasons, be sure to read the SAFETY INSTRUCTIONS and INSTALLATION chapters before first powering-up! We also recommend reading the CONTROL ELEMENTS chapter for information on how to connect iCLOCK! The device is fully operated using the display and the four cursor buttons on the front panel.
O P E RAT I O N \\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> MENUS AND FUNCTIONS Main Menu Page When the device is switched on, a boot period of approximately seven seconds will occur. During this period, the display will show two pages in succession. The first of them provides information on the current firmware version. ! All user-specific parameter settings are available furthermore when power is restored. i CLOCK - V2 .
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> OSCI FAIL (status message) OSCILLATOR FAILED, indicates that the internal reference clock oscillator has failed. ! Error Messages If one of the messages OSCI FAIL, MAIN1LOST or MAIN2LOST is displayed, safe operation is not guaranteed! Contact the technician in charge immediately! MAIN1LOST (status message) MAIN 1 LOST indicates that the primary supply voltage or the primary internal power supply have failed.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> PAL 1, -2 (setting) PAL1, -2 allows for synchronizing the internal video reference generator to PAL or SECAM video signals with a frame rate of 25 fps, 625 lines, and a line frequency of 15.625kHz. NTSC 1, -2 (setting) NTSC1, -2 allows for synchronizing the internal video reference generator to NTSC video signals with a frame rate of 29.97fps, 525 lines, and a line frequency of 15.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> As the synthesizer is capable of continuously supplying the adjusted iCLOCK output signals, even a manual clock source change on an input (by replugging the clock lines) is supported during operation! It is not important whether the change occurs, for example, from a PAL SD video signal to a Word Clock or GPS signal.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> This function also ensures a redundant (failsafe) availability of the video output signals. If the external source fails temporarily or permanently, the video generator will continue generating its output signals based on the last recognized clock rate. If the external source returns to operation, any differences to the previous rate will gradually be corrected to maintain flawless on-air operation in e.g.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Configuring the Word Clock Outputs Due to the internal signal phase corrections the synthesizer can re-lock temporarily when switching Word Clock clock frequencies. This does not affect the output signals or functionality of iCLOCK. The WCLK OUT 1–4 display pages allow for configuring the eight wordclock outputs provided by the iCLOCK standard version .
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LEVEL / TERM (function) LEVEL / TERMINATION This function allows for adjusting the Word Clock signal level of the selected output pair and for entirely disabling the output. The page always displays the output level and the corresponding internal termination of the output pair. The factory default is 2.6 V/75 R. 2.5 V / 75 R (setting) With this setting, the Word Clock signal is output with a level of 2.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> DIST DIST does not provide redundancy for the AES/EBU outputs. If the external AES/EBU or S/P-DIF clock source fails, the associated AES/EBU-output pair will fail, too! (setting) DISTRIBUTION This setting allows for forwarding an input AES3 or S/P-DIF signal to the selected AES/EBU output pair using a hardware bypass.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LOCKSTAT (function) LOCK STATUS This function allows for changing the synchronization status stored in the channel status bits (byte 0, bit 5) of the clear-frame signal of the selected AES/EBU output pair. The factory default is LOCKED.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> FORMAT If the professional format is selected, the physical parameters of the output terminals (unbalanced operation, level, and impedance) will remain unchanged! The functions and settings displayed on the S/P-DIF menu pages are automatically adapted with regard to the channel-status bits of the professional format.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Setting System Functions System parameters allow for setting functions that affect no specific output clock formats but all output signals or the global device functionality of iCLOCK. Four menu pages named GLOBAL 1/4 to GLOBAL 4/4 are provided by iCLOCK standard version. Functions and settings on the GLOBAL 1/4 menu page: < | | <| < GLOBAL 1/4 PULLs OFF VAR I SPEED + 0 . 0000% PULL RANGE + / - 5 .
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> + 0.0000 % (setting) The varispeed factor can be set here in miniature steps of 0.0001 %. The step width can be changed by moving the cursor (see figure at page 25). The factory default is + 0.0000 %. PULL RANGE Example +/- 1.0 % ... +/-20.0 % (setting) The pull range can be set here in steps of 1.0 %.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> RESET (function) RESET This function allows for resetting all function and parameter changes to their respective factory defaults, i.e. to the settings of the iCLOCK when it is switched on for the first time. GO, SURE ? (setting) GO enables the RESET function. When the ENTER button has been pressed, a confirmation request (SURE?) will be displayed.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Functions and settings on the GLOBAL 4/4 menu page: < | | < GLOBAL 4/4 TERM I N1 / I N2 POWER SUPPLY SOFT ON ON 1 - OK 2 - N . A . V211 GLOBAL 4 / 4 This menu page provides information in internal system statuses and cannot be edited. TERM IN1 / IN2 TERMINATION - INPUT1 / INPUT2 This informs on the internal termination status of the two universal clock-source inputs INPUT1 and INPUT2.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Preset Management This functionality is available from software versions, V2.10 and V2.11, or higher. Does your iCLOCK or iCLOCKdp not include one of these software versions, please contact your local MUTEC dealer or distributor for an update. Software V2.11 offers in combination with the new optional iC-ALARM/GPI interface the possibility to switch over different presets externally via GPIO control.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> GPICNTRL (setting) GPIO CONTROL activates the preset selection via the first three GPIO inputs of the iC-ALARM/GPI interface (encoded binarily). NAME (function) NAME Here you can assign individual names for the presets. One name can consist of a maximum of eight letters. PRESET01 – 08 (setting) These are the factory default names. NUMBER NUMBER This informs on the currently active preset number, 01 – 08.
ANHANG \\\\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Loading and restoring the factory default preset 1) To load a preset: Select the LOAD item from the OPERATION menu. Quit the OPERATION function by pressing the ENTER key, then change to the NAME function. Select one of the PRESET01-08 memories by their preset number or name using the up/down keys and confirm by pressing the ENTER key. Press the ENTER key twice to switch to the PRESET function.

\B E D I E N E L E M E N T E >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> iCLOCK TECHNOLOGY Functional Principle iCLOCK‘s principle operation is completely different to conventional products. The customer, as a matter of priority, defines the clock rates and formates which are constantly available at the outputs – not depending on the incoming reference signals! Limitations regarding defined combinations of input and output clock signals do not exist for iCLOCK.
C LO C K T E C H N O LO GY \\\\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Sequence Synchronization Example If the first source (REF1) has failed, the synthesizer tries automatically to synchronize the next source (REF2). When no reference is available the system waits until the timing interval of the LONEREF function (A) has elapsed to synchronize the next reference.
\B E D I E N E L E M E N T E >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> iCLOCK EXTENSIONS iC-ALARM up to operating system V2.10 The optional iC-ALARM interface (ordering no. 8005-065) is only suitable for iCLOCK software versions up to V2.10. From V2.11 you must (!) use the iC-ALARM/GPI interface, see below. The iC-ALARM interface enables to trans-fer signals depending on three different critical operating conditions.
EXTENSIONS \\\\\\\\\\\\\\ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> iC-ALARM/GPI from operating system V2.11 or higher The optional iC-ALARM/GPI interface (ordering no. 8005-066) is only suitable for iCLOCK software version V2.11 or higher. The iC-ALARM/GPI interface offers same basis functionality like the previously described iC-ALARM. New to the iC-ALARM/GPI interface is its GPIO function (see page 31).
