Devices Tab (Global Settings)

Updated 5 days ago · 4 min readIntermediate

The Devices tab in FMX Global Settings lets you configure all peripheral hardware connected to your photo booth. This includes printers, microphones, LED lighting, remote controls, sensors, and scanner devices.

Devices Tab

Printers

FMX supports multiple printer configurations for different output formats.

Main Printer

  • Printer Selection -- Choose your primary printer from the dropdown. FMX lists all printers installed on the system.
  • Printer Target -- Choose the default Windows printer, FMPrint cloud printing, DNP Hot Folder, or a specific installed printer.
  • Orientation -- Choose automatic orientation handling or a fixed printer orientation.
  • Compatibility -- Select the Windows driver compatibility mode used for local printing.
  • Print Padding -- Adjust left, top, right, and bottom padding in pixels for local printer alignment.
  • Printer Pool / Load Balancing -- When enabled, FMX distributes print jobs across multiple printers of the same model. This is useful for high-volume events where a single printer cannot keep up with demand.
  • Print limit per event -- Optionally cap the number of local prints for the currently selected event. A value of 0 means unlimited.

When FMPrint is selected, local printer settings are managed by the FMPrint service machine rather than by the booth device.

When the DNP Hot Folder is selected, FMX routes 4x6 layouts to configured 4x6 folders and strip layouts to configured 2x6 folders. DNP Hot Folder controls include overcoat finish and separate 4x6/2x6 default and matte folder paths.

Strips Printer

  • Strips Printer -- Select a dedicated printer for 2x6-inch photo strips. This can be the same printer as the main printer or a separate device optimized for strip output.

Tip: Test your print settings with a few sample prints before an event. Confirm that borderless mode is working correctly and that colors match your expectations. Different paper types can shift color output.

Microphone

  • Microphone Device -- Select the audio input device for video recording. FMX lists all available recording devices on the system. Choose the microphone that is positioned closest to your guests for the best audio quality.

LED Ring

FMX detects Arduino-based LED ring lights connected through USB serial. The Devices tab shows connection status for the LED Ring. LED effects themselves are driven by workflow/device commands rather than a pattern editor in the Devices tab.

Key Fob (Remote Control)

The key fob is an Arduino-based wireless remote with 4 configurable buttons, useful for operator-controlled booth management.

  • Buttons A, B, C, D -- Each button can be assigned a custom action from the available action list.
  • Debouncing -- Built-in debounce logic prevents accidental double-presses. FMX ignores rapid repeated signals from the same button within a short time window.

Configure each button to match your operating workflow. Common assignments include triggering capture, restarting the experience, opening the gallery, or advancing to the next step.

Proximity Sensor

The proximity sensor enables hands-free auto-triggering of the photo booth experience when a guest approaches.

  • Threshold -- Set the detection sensitivity from 1 (most sensitive) to 1000 (least sensitive). Lower values trigger the sensor at greater distances; higher values require the guest to be closer.
  • Consecutive samples -- Require multiple readings before triggering to reduce false positives.
  • Hold time -- Require the threshold condition to remain true for a minimum time.
  • Require rising edge -- Trigger only when the sensor crosses from inactive to active.
  • Timeout behavior -- Configure timeout and whether the workflow can continue when no trigger is detected.
  • Max value -- Optional sanity cap for filtering invalid sensor readings.

Adjust the threshold based on your booth layout and the amount of foot traffic in the surrounding area to avoid false triggers.

Tip: In high-traffic environments, set a higher threshold so only guests who are directly in front of the booth trigger the sensor. In controlled environments, a lower threshold provides a more responsive experience.

Hand Scanner

FMX supports WIA/USB-compatible hand scanners for capturing physical documents, prints, or artwork.

  • Connection -- WIA (Windows Image Acquisition) over USB.
  • Auto Crop -- Automatically detects and crops the scanned content from the background.
  • Auto Rotate -- Corrects the orientation of scanned images.
  • Auto Compress -- Reduces file size of scanned images for efficient storage and upload.

Payment Terminal

The Devices tab includes the Payment Terminal card. Expand it to choose the payment provider and configure the visible provider settings for pay-per-use workflows.

  • Payment Provider -- Choose None, Nayax, Pulse, Shopify, or Stripe.
  • Nayax -- Configure COM port, baud rate, currency, default amount in cents, optional product code, and support logging options.
  • Pulse -- Configure COM port, baud rate, cents per pulse, and timeout.
  • Shopify -- Configure shop domain, poll interval, timeout, simulator mode, and test connection.
  • Stripe -- Configure poll interval, timeout, simulator mode, and test connection.

There is no separate Payment tab in the current FMX Windows sidebar. See Payment Settings for the provider-specific details.
