    Rev 2 firmware brings some new functions to the DXD-8, mainly the possibility to install the optional PTP firmware and GPS hardware. Time and date are now part of the DXD-8. Rev 2 includes new menus 7.1 to 7.4, a new Main Rotation TIME & DATE display page and a new TIME status display.

  • Page 5: Installation

    You should read this manual to familiarize yourself with the DXD-8 features. The following simple steps are only provided to get you started right away. Connect the power supply to the Power A jack and plug the IEC cable into a wall outlet. The DXD-8 will turn on as soon as power is connected.

  • Page 6: I/O's Description And Cable Requirements

    4.5 DC POWER The DXD-8 requires 12VDC @ 18W. Acceptable range is 12VDC +/-15%. The external supply provided with the DXD-8 accepts 100 to 240 VAC input at 50 - 60 Hz so it is suitable for use anywhere in the world.

    For more on Alternate Reference, see chapter 11. Note that, if there is no alternate reference, the DXD-8 will always revert to INTERNAL if the reference disappears. There are no additional fields when the reference source is ‘INTERNAL’.

  • Page 13: Bnc Outputs

    7.3 BNC Outputs The DXD-8 generates 4 different reference signals simultaneously, each of them sent to one of the four BNC output pairs, as described below. Each of these universal output groups can output WC, AES, Video Sync or 10MHz.

    Page 14 DXD-8 User Manual (rev 2.10) used for musical applications, the speed adjustment is measured in cents (semi tone/100). The VSO range is +/- 200 cents, i.e. 2 whole tones (+12.2562% to -10.9101%). NOTES: When adjusting the VSO cents value in the menu, the changes take effect immediately. There is no need to press [ ] for every speed change.

    7.7 Time Without PTP or GPS, the base DXD-8 deals with references that do not include time and date such as video sync or word clock. However, the generated outputs are always referenced to the PTP epoch. For that reason, when no Time Of Day source is available to the DXD-8, the internal Real Time Clock will provide Time and Date.

    To purchase please contact your Brainstorm dealer. Feature Keys are unique for each serial number. The DXD/LTC is a firmware upgrade for the DXD-8. Please refer to the DXD/LTC manual for details on the Time Code menus. 7.9 Presets Ten different user settings configurations can be stored for quick recall. The 10 memory locations are labeled Preset 1 through Preset 10.

    8. Time of Day Although PTP is optional on the DXD-8, it is PTP ready and Time of Day is an essential part of its design. In a PTP network, the devices all need to know the Time of Day, i.e. year, month, day, hour and seconds, even nanoseconds, to achieve frequency and phase synchronization.

    BNC inputs is set as the reference). Current choices for external sources are PTP and GPS, both optional on the DXD-8. During a Time Jam, the DXD-8’s TOD will reset to the time of that source of time before locking to the BNC input.

    10. External Reference Failover (BNC) In the event of failure of the external reference, the DXD-8 has 2 different scenarios to insure that the Sync outputs remain safely uninterrupted.

    12. Output Deviation Indication: The DXD-8 continuously monitors each output group and looks for timing deviations. The length of each frame is compared to the previous one and, if a deviation is found, it is reported on the OUTPUTS page of the main rotation display by changing the color of the blue boxes on the left side where the output groups are identified.
