  • Welcome to :pulse

    Welcome to :pulse

    Thank you for choosing Timecode Systems' :pulse as your mini base station solution. With its extremely accurate internal clock, :pulse is a reliable timecode/word clock/genlock generator and multi-channel digital timecode transceiver.

    In this user guide, you will find information on how to set up your :pulse for:

    • Synchronising timecode with other Timecode Systems devices, Sound Devices 6-series sound mixers, and video cameras
    • Remote monitoring*
    • Remote control*.

    * For remote monitoring and remote control, you can use our free BLINK Hub app, which connects to your :pulse via Wi-Fi or Ethernet.

  • Display and Controls - :pulse

    Display and Controls



    The antenna is for the digital transceiver module and it operates in the 868MHz to 923MHz ISM bands.


    OLED Display

    The OLED display is a blue 128 x 32 pixels pixels screen. When you switch on the :pulse, all status information, messages, and menus and options are shown on this screen.

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


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

    Colour Description

    A flashing green LED shows that Wi-Fi is off.

    Blue A flashing blue LED shows that Wi-Fi is on.

    A flashing red LED shows that there are warning messages. The warning messages are displayed on the OLED.

    Simultaneous Flashing The LED acts as an indicator for synchronised Timecode Systems devices. If there are multiple devices in a network, their LEDs will flash simultaneously when they are synchronised. If a device is in the network and has its LED flashing at a different time to the other devices, that device is not synchronised.

    Control Knob

    You can use the control knob to turn the :pulse on and off, navigate through menu options, and select options. The control knob acts as a button and a dial.

    To turn the :pulse on and off, or to select an option in a menu, you should press the end of the control knob. You will hear (and feel) the button inside the control knob press down.

    To navigate through the available menus and options and to increase or decrease a value, you should turn the control knob. You can turn the control knob clockwise or anti-clockwise to cycle through the available options or values.

  • :pulse Ports


    Your :pulse has a variety of ports for connecting with other devices and chargers.



    Port Description
    LEMO 9-36V DC Power supply input. This is a LEMO 2 socket.
    LEMO DATA For connecting your :pulse to third-party equipment. This is a LEMO 9 socket.
    LEMO TC For timecode input and output. This is a LEMO 5 socket.
    TC/SYNC (BNC) For outputting genlock, word clock, or timecode to third-party equipment.

    The Ethernet ports allow you to use our BLINK Hub or other apps via a wired connection rather than Wi-Fi. Simply connect your :pulse to a network via a wired Ethernet connection and then run the apps on your laptop PC or MacBook.

    If you are using ARRI® Alexa® cameras, the Ethernet ports provide an Ethernet to Wi-Fi bridge. This enables remote control and metadata logging.

    Micro USB 2.0

    You can use the micro USB 2.0 port to:

    • Charge your :pulse (via a USB 2.0 charger and cable). The micro USB port is a 5V power IN socket.
    • Connect your :pulse to a PC or Mac for downloading firmware, FPGA updates for the on-board chip, and web page updates for the BLINK Hub app.

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


  • Charging your :pulse

    Charge your :pulse

    The :pulse unit has a built-in battery and can also be powered by an external power source. The battery is charged when the :pulse is connected to an external power source.

    There are multiple ways to power your :pulse:

    Connection Use
    LEMO port (9-36V DC) Mains power adaptor with LEMO compatible connection.
    Micro USB Micro USB 2.0 charger connected to power source.
    Ethernet Ethernet cable connected to power source.

    You can reduce the amount of power the :pulse uses by turning off the Wi-Fi and Ethernet features. If you need to have Wi-Fi turned on, there is a stealth mode which will turn off Wi-Fi automatically if the external power is lost.

    For more details, see Set up Wi-Fi for Data Streaming and Set Up Ethernet for Data Streaming.
