Transmitter Display Operation

Updated

Bolt 4K’s configuration menus can be accessed from either the transmitter's front panel display or from the Bolt app.

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).
  • INFO - Displays the voltage and internal temperature of the unit.
  • HDMI STATUS - Displays the current HDMI 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 transmitter's configuration options.


WIRELESS SETTINGS

ENABLE BROADCAST MODE (BOLT 4K MAX/ BOLT 4K LT MAX ONLY)
Broadcast Mode allows you to transmit to multiple receivers simultaneously (non-DFS frequencies only), while also extending your Bolt 4K's transmission range. 

  • Broadcast Mode Disabled (Standard Multicast Mode) - Transmitter and connected receiver(s) coordinate and maintain two-way communication with each other to optimize frequency usage and video transmission. 
  • Broadcast Mode Enabled - Data uplink channel is disabled, allowing the transmitter to connect to an unlimited number of    receivers, as long as they have already been paired. To achieve even better range performance, attach the receiver to your Bolt Panel Antenna while in Broadcast Mode. 

NOTE: Bolt 4K 750 and 1500 receivers will not link to a Bolt 4K MAX transmitter in Broadcast Mode, even if they were previously paired. You must use a Bolt 4K MAX receiver, otherwise the transmitter's OLED will display Broadcast Not Supported.


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 within the selected wireless region (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.


VIDEO QUALITY (BOLT 4K/ BOLT 4K LT ONLY)
The Video Quality menu lets you adjust the balance between your signal’s maximum range and quality according to the number of antennas used to transmit fine information. Bolt 4K has three picture quality levels that vary based on the lowest quality link or the furthest receiver.

  • Auto Mode - (Default) Transmitter automatically determines how many fine antennas are needed based on the range and signal quality.
  • Longer Distance Mode - (One fine antenna) Maintains the maximum range in situations where other sources of interference might  be present, but will slightly reduce your video signal’s maximum quality.
  • Better Quality Mode - (Two fine antennas) Maintains higher signal quality, but reduces the maximum range.
  • Best Quality Mode - (Three fine antennas) Ideal for complex, high contrast scenes that require the highest possible quality.
  • Low Power Mode - (One fine antenna with shorter range) Reduces the transmitter's total power consumption by about 1.5W, and may reduce any unwanted interference in multi-system environments.

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. Transmitters can store up to six paired receivers in its device registry. Pairing more receivers than the maximum six allowed will remove the first paired unit from the device registry.


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

LOCK KEYPAD
Enabling the Lock Keypad feature prevents the menu joystick from being used, preventing any accidental or unauthorized configurations.  To unlock, press and hold the menu joystick upwards for five seconds or until the display reads "KEYPAD UNLOCKED."


BLUETOOTH
Use the Bluetooth menu to enable or disable Bluetooth communication.

  • Enable Bluetooth - Allows transmitter and receiver to be paired and communicate with the Bolt App
  • Use Bluetooth PIN - Enables the use of a PIN for authentication when using the Bolt App.
  • Change PIN - Press the Menu joystick towards the right to change the Bluetooth PIN

NOTE: Bluetooth is disabled by default. In order to configure your Bolt 4K devices via the Bolt App, you must first enable Bluetooth.


RESET ALL SETTINGS
Reset all configurable options to their factory defaults.


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

DEVICE INFO
Reset all configurable options to their factory defaults.

BLUETOOTH SETTINGS (BOLT 4K LT-HDMI ONLY)

Use the Bluetooth menu to enable or disable Bluetooth communication.

  • Enable Bluetooth - Allows transmitter and receiver to be paired and communicate with the Bolt App
