• UltraSync ONE for Synchronisation

    UltraSync ONE for Synchronisation

    UltraSync ONE is a highly accurate timecode generator and multichannel digital timecode transceiver.

    You can use your UltraSync ONE as:

    • a stand-alone device to provide timecode, genlock, and word clock to your camera or sound mixer/recorder
    • a timecode master, where it provides timecode to other Timecode Systems products for synchronisation
    • a timecode slave, where it receives timecode from a 'master' device and then provides this timecode to your camera or sound mixer/recorder.

    You can learn more about these modes in Networks and Modes.

    Tip: If you use UltraSync ONE with a :pulse, you have free access to the BLINK Hub app. You can use the app to configure and monitor your UltraSync ONE. For more details, see Remote Settings using BLINK Hub .

  • Switch UltraSync ONE On/Off

    Switch UltraSync ONE On and Off

    To switch your UltraSync ONE on:

    1. Press and hold the Select button.

      The UltraSync ONE screen lights up and displays the message:

      Push Up/Dn twice to switch on

    2. Press the up or down button twice to turn on the UltraSync ONE. This extra step is designed to prevent you from accidentally turning the UltraSync ONE on. If you do not press the up or down button twice within a 5 second period, the UltraSync ONE stays off.

    When the UltraSync ONE comes on, it shows the main screen by default (see Display and Controls).

    Note: If your UltraSync ONE does not come on when you press and hold the Select button, the battery may need to be charged (see Charging your UltraSync ONE). If your UltraSync ONE is on and the battery charge is running low, the LED light turns red.


    To switch your UltraSync ONE off:

    1. Press and hold the Select button until the following message is displayed:

      Push Up/Dn twice to switch off

    2. Press the Up or Down button twice to turn off the UltraSync ONE.

    Note: If you do not press the up or down button twice within a 5 second period, the UltraSync ONE stays on and the screen reverts to showing the main display.

  • Display and Controls - UltraSync ONE

    Display and Controls

    Your UltraSync ONE is easy to set up and use. It has a simple menu system for applying the device's settings.

    To learn about connecting other devices to your UltraSync ONE, see Ports.



    When you switch on your UltraSync ONE, the OLED lights up and presents you with status information. The OLED is also where you will get to see messages, other status information, and the menus and options you will use to set up your UltraSync ONE.

    To learn about the various status displays, including the 'Main' screen shown above, see Main Screen.

    Status Indicator LED

    The LED to the right of the OLED display acts as a colour-coded status indicator.

    Colour Description

    The LED will flash green if:

    UltraSync ONE is in Free Run/Jam-EXT mode and has successfully jammed to a 'master' timecode signal.

    UltraSync ONE is in RF Slave mode or EXT LTC Int mode and is synchronised with the master.

    UltraSync ONE is the master device in an RF network.

    The LED shows a solid green light if the UltraSync ONE is switched off and the battery is fully charged.


    The LED will flash blue if:

    UltraSync ONE is in Free Run/Jam-EXT mode and is waiting for a jam signal from a 'master' timecode source.

    UltraSync ONE is in RF Slave mode or EXT LTC Int mode and is not synchronised with the master.


    The LED will flash red if:

    UltraSync ONE is powered down and charging. (The LED does not show red if the UltraSync ONE is charging while it is switched on).

    UltraSync ONE has a low battery.

    UltraSync ONE is resynchronising with a master device (LED flashes red twice, very quickly).

    If you are unfamiliar with master and slave devices, you can learn more in Master and Slaves.

    Up and Down

    Use the Up and Down buttons to scroll through the menu options and top-level status display screens.


    Use the Select button to choose a menu or option. You will also use Select to switch your UltraSync ONE on and off.

    To make a selection or change a setting, use the Up and Down buttons to scroll to a menu or option. Press the Select button once to confirm.

    To switch your UltraSync ONE on or off, press and hold the Select button (see Switch UltraSync ONE On and Off, for more details).

  • Ports - UltraSync ONE


    Your UltraSync ONE has three ports, which you can use to connect to an external device (LTC or SYNC output) and a USB-C charger.

    Port Description
    SYNC Use to output genlock to a camera, word clock to a sound mixer/recorder, or Linear Time Code (LTC) to any compatible device.
    LTC Use to send or receive Linear Time Code (LTC).

    Use to charge your UltraSync ONE, by connecting it to a power source. For more details, see

    Charging your UltraSync ONE.

    You can also use the USB-C port to connect to a computer for downloading updates.

    Please visit www.timecodesystems.com/support/firmware for instructions on how to update the firmware of your UltraSync ONE.

    Note: For best operation and access to the latest features, keep your UltraSync ONE up-to-date with the latest firmware.

    DIN 1.0/2.3 to BNC Cables

    The SYNC and LTC ports have DIN 1.0/2.3 connectors. To connect other devices to these ports, use the DIN 1.0/2.3 to right-angled BNC cables that are supplied with your UltraSync ONE.

    The cables are colour-coded for ease of use.

  • Charging your UltraSync ONE

    Charging your UltraSync ONE

    UltraSync ONE has a built-in battery and it should provide a minimum of 25 hours life from a single charge. We calculated the 25 hour life based on your UltraSync ONE being used with RF, genlock/word clock, and the OLED screen all being used at full capacity. You can make the battery charge last even longer by not using these features or by dimming the OLED brightness.

    Note: Battery life may be reduced if your UltraSync ONE is used in extreme temperatures. Very hot and very cold conditions can affect battery performance.

    If the battery in your UltraSync ONE is running out of power, the LED flashes red and the following message is displayed on screen:

    The low battery power is also indicated on the battery icon in the bottom-right of the main screen, next to the channel number. The amount of white in the inner of the battery icon represents the amount of charge left in the battery. In the image below, the inner of the battery icon is black, which means there is very little power left in the battery.

    It is also shown on the battery status screen (see Power and Battery Status).

    To recharge the battery, you will need the USB-C to USB cable that is supplied with your UltraSync ONE and a compatible charger socket (not supplied). Connect the USB-C to USB cable to the power source and to the USB-C port on the left-hand edge of the UltraSync ONE (see Ports).

  • Mounting your UltraSync ONE

    Mounting your UltraSync ONE

    To mount your UltraSync ONE, fix a hook-fastening Velcro strap to the middle of the rear side of the unit. You can then attach the UltraSync ONE to other equipment.

    The typical range for synchronisation with a master is approximately 200m (656 feet, 219 yards). This range is based on an uninterrupted line of sight. If there are obstacles between a slave and master, the range can be reduced.

    *Typical range. The range can vary.
