Receiver Display/OSD Operation

Updated

Bolt 4K’s configuration menus can be accessed from either the receiver's front panel display or from the Bolt app. When enabled, the receiver’s configuration menus are also displayed via On-Screen Display (OSD) on a connected monitor.

RECEIVER STATUS SCREENS

Press the menu joystick to cycle through the status screens or to return from the menu.

  • MAIN STATUS - Displays the status of the wireless receiver, along with the current video resolution, frequency, and link quality (if connected).
  • TIME CODE - Displays the current time code if received from the transmitter.
  • INFO - Displays the voltage and internal temperature of the unit.
  • TX INFO - Displays the name of the transmitter it is paired to.
  • HDMI STATUS - Displays the current HDMI color output

CONFIGURATION OPTIONS

Most of the options listed in this section can also be configured using the Bolt App. Use the Menu Joystick to navigate the configuration menus.

SWITCH TX (BOLT 4K/BOLT 4K LT ONLY)

Bolt 4K receivers can pair with up to four transmitters at a time. Switch TX allows you to quickly switch from one paired transmitter's camera feed to another paired transmitter. This feature is especially useful in multi-camera situations when you need to switch to a different camera's view mid-shoot, without having to perform the pairing process every time. NOTE: The transmitter(s) need to first be paired with the receiver.

WIRELESS SETTINGS

ENABLE FIXED FREQUENCY
Fixed Frequency Mode bypasses any automatic frequency switching logic, allowing your Bolt 4K system to always attempt to connect on a specified frequency. Once a frequency is selected, the transmitter will only use that frequency. This allows the transmitter to link/reconnect to the receiver much faster. After enabling Fixed Frequency mode, navigate to Frequencies and select a frequency not in use (non-DFS frequencies only). For best results, ensure that both the transmitter and receiver have Fixed Frequency Mode enabled, and use the Spectrum Analyzer (on the receiver's front panel or the Bolt app) to search for the least congested frequency to use.

  • Fixed Frequency Mode Disabled - Bolt 4K scans all available channels and repeatedly switches from one frequency to the next during transmission.
  • Fixed Frequency Mode Enabled - Bolt 4K connects to one specific frequency.

NOTE: By default, Bolt 4K will select the lowest available frequency from the Frequencies list if one has not been selected beforehand.


SELECT BANDWIDTH
The Bandwidth menu lets you choose between 40MHz (default) and 20MHz operating modes. Ensure that both the transmitter and receiver are set to the same bandwidth with a resolution of up to 1080p60. For all available frequencies, refer to the FREQUENCIES BY REGION chart.

  • 20MHz - Reduces the amount of bandwidth by half, effectively doubling the number of usable frequencies while decreasing interference.
  • 40MHz - (Default) Increases the amount of bandwidth by bonding two 20MHz channels, allowing for faster transfer rates but increased interference.

NOTE: 20MHz mode supports HD/3G resolutions up to 1080p60. Resolutions up to 4k30 are also supported, but downscaled to 1080p before transmission (4k50/59/60 is not supported).


SELECT FREQUENCY
The Frequencies menu contains a list of all available frequencies. Bolt 4K will automatically select an operating frequency when multiple values are selected. If both the transmitter and receiver have Fixed Frequency Mode enabled, you can only select one frequency for Bolt 4K to use. Frequencies marked with (DFS) must be scanned for one minute before they can be used, but are typically less crowded. For all available frequencies, refer to the FREQUENCIES BY REGION chart.


TOOLS (BOLT 4K/BOLT 4K LT ONLY)

SIGNAL QUALITY GRAPH
The Signal Quality Graph indicates the quality and reliability of the signal being received according to the amount of interference that is present between the RX and TX. Signal Quality is represented in percentages: 

  • Figures below 30% indicate poor signal quality
  • Figures between 30% and 45% indicate fair signal quality
  • Figures above 45% indicate good signal quality

SPECTRUM ANALYZER
The built-in Spectrum Analyzer provides a visual indication of channel noise and saturation across the entire available frequency range. Move the Menu joystick left and right to select a frequency, then up and down to enable or disable it. 

TEST PATTERN
The Test Pattern menu allows you to select a video resolution format to output a test pattern over HDMI or SDI. 

  • Resolutions List- Select a specific output resolution: 
    • 4Kp - 23.98/24/25/29.97/30/50/59.94/60
    • 1080p - 23.98/24/25/29.97/30/50/59.94/60
    • 1080psf - 23.98/24/25/29.97/30
    • 1080i - 50/59.94/60
    • 720p - 50/59.94/60
    • 480p - 59.94/576p - 50 (via HDMI ports only)
    • 480i (NTSC)
    • 576i (PAL)

Frequencies are represented by bars; the higher the bar, the more congested that frequency is. Bars without a dot (1) indicate the frequency is not as saturated and can be used. Bars with a dot (2) indicate the frequency is too saturated to connect to. Faded bars (3) represent a frequency that is unavailable for use due to restrictions in particular regions.

PAIR

Enable pairing on transmitters and receivers. Bolt 4K units purchased as a set (TX and RX) are paired by default, requiring no additional configuration. If the units were purchased separately, or if they have never been paired, you will need to complete the PAIRING PROCESS. Once Pairing is complete, there is no need to repeat the process unless the TX or RX's OSD name has been modified, or if the region has been changed. To confirm if your devices were paired successfully, open either the Unpair menu (TX) or the Switch TX menu (RX) and verify that the paired device is listed. NOTE: Before starting the pairing process, ensure that both the transmitter and receiver have the same firmware version and have Bluetooth enabled.

UNPAIR

Unpair and remove devices from your unit's paired device registry. This feature is useful in situations when paired devices are no longer being used and need to either be removed from the registry, or replaced. Receivers can store up to four transmitters in its device registry.

ADVANCED SETTINGS (BOLT 4K/BOLT 4K LT ONLY)

HDMI/SDI OUTPUT (BOLT 4K/BOLT 4K LT ONLY)

You can choose to match the video source’s resolution (Same As Input), or choose from the resolutions listed. If using the receiver with a recorder or monitor that is sensitive to video signal changes, select Continuous Output to ensure the signal stays constant even if the link is interrupted. Keep in mind that selecting Continuous Output adds a small delay to the video output. Selecting SD, HD, or 6G-UHD matches the video source's frame rate while adjusting the resolution. This is useful for when you need to down-convert a 4K video to display on an HD monitor.

  • Continuous Output - Video signal output stays constant when using a monitor or recorder that is sensitive to video signal changes.
  • Same as Input - Matches the transmitter's video source resolution.
  • SD - Matches the TX frame rate and outputs SD resolution.
  • HD - Matches the TX frame rate and outputs1920x1080p.
  • 6K-UHD - Matches the TX frame rate and outputs 3840x2160.
  • Resolutions List- Select a specific output resolution: 
    • 4K (DCI) - 23.98/24/25/29.97/30/50/59.94/60
    • 4K (UHD) - 23.98/24/25/29.97/30/50/59.94/60
