Bolt 4K Monitor Module RX Quick Start Guide

Updated on

Receive lossless 4K video from up to 750/1500 ft line-of-sight with the Bolt 4K Monitor Module RX. The module mounts onto the back of a SmallHD Cine 7 or 702 Touch monitor and can wirelessly transmit up to 4K30 video with 10-bit 4:2:2 HDR support to any Bolt 4K transmitter.

The Bolt 4K Monitor Module TX features improved metadata, range, and compatibility over its predecessors, and includes built-in AES-256 encryption with RSA 1024 key pairing to protect your video.



NOTE: Attaching a Monitor module to any wireless version of the Smart 7 monitor will automatically disable your monitor's internal wireless and instead use the module's wireless capabilities. To use the monitor's wireless capabilities, simply connect power to the monitor instead of the module, then navigate to the WIRELESS SETTINGS and enable WIRELESS.

  1. Remove the battery plate from the back of the Smart 7 monitor.
  2. Detach the cover plate from the back of the Bolt 4K Monitor Module to expose the JST connector.
    NOTE: There is no need to disconnect the JST connector.  
  3. Place the monitor module firmly against the back of the Smart 7 monitor. Ensure that the two top mounting holes, connector pins, and micro USB align with their corresponding terminals.
  4. Insert two M3 socket-head screws through the two top mounting holes on the monitor module and
    into the back of the monitor. DO NOT OVER-TIGHTEN.
  5. Optional: Attach a V-mount or Gold-mount battery plate to the monitor module, then tighten the four
    Phillips screws. NOTE: Before attaching the battery plate to the monitor module, ensure the wires are tucked into the plate so that they do not obstruct the release button’s operation.
  6. Insert, then tighten the 1/4”-20 hex screw to secure the monitor module assembly against the back of
    the monitor. DO NOT OVER-TIGHTEN.
  7. Attach a compatible battery to the battery plate (optional), or connect power to the module’s 6-18V
    DC input using the included A/C adapter. NOTE: Ensure the A/C adapter is connected to the module
    and NOT the monitor.
  8. Attach antennas to the monitor module via the threaded RP-SMA connectors (A), then connect an
    HDMI cable from the module to the monitor.
  9. Turn the system on by pressing and holding down the monitor’s power button.

You will need the following:

  • Lens Mapping License
  • SmallHD/Teradek RT Interface Cable
  1. Connect a cable from the controller’s wired mode connector to one of the monitor’s AUX ports.
  2. Tap the screen on the monitor and navigate to ADD NEW TOOL>ADD ONS.
  3. Select TERADEK RT.
  4. The Lens Map Overlay will appear on the right and move according to controller’s knob movements.
