Tax included Shipping calculated at checkout.

The Blackmagic Design Spares - Smart Videohub 20x20 - PCB Front is the dedicated interface and control board for the 20x20 model of the Smart Videohub. This component is situated directly behind the front panel and acts as the physical interaction layer between the operator and the main routing engine.

Front Panel Control Logic

This PCB is responsible for translating every manual command into data that the Main PCB can execute. It manages the specialized components that allow for "at-the-router" crosspoint changes:

  • Rotary Encoder Interface: Houses the logic for the machined metal spin knob, allowing for high-speed scrolling through dozens of inputs and outputs.

  • Button Matrix: Controls the tactile buttons for "Take," "Clear," and menu navigation, including their integrated backlighting.

  • LCD Driver Logic: While the LCD itself is often a separate panel, this board contains the bridge circuitry that sends video thumbnails and source/destination labels to the screen.

Visual Feedback and Monitoring

The Front PCB is essential for the Videohub's unique "Visual Routing" feature. It coordinates the display of live video icons on the front panel LCD, ensuring that as you scroll through ports, you get a real-time visual confirmation of the signal. If the front display is flickering, the buttons are unresponsive, or the spin knob is skipping entries, the Front PCB is the likely culprit.

Connectivity and Communication

The Front PCB connects to the Main PCB via a high-density ribbon cable. This connection is the lifeline of the front panel, carrying:

  • Power: Drawing voltage from the main power distribution to run the LCD and button LEDs.

  • Command Data: Sending user-initiated routing changes to the crosspoint matrix.

  • Status Data: Receiving label information and signal status from the Main PCB to display to the user.

Key Features

  • Genuine OEM Part: Specifically engineered for the Smart Videohub 20x20 chassis.

  • Direct Tactile Restoration: The primary fix for mechanical failures of the front buttons or the rotary encoder.

  • Integrated Design: Comes pre-populated with all necessary switches and the mounting bracket for the spin knob.

  • Plug-and-Play Internal Interface: Designed for a straightforward connection to the internal wiring loom.

Technical Installation Note

Replacing the Front PCB is less invasive than a Main PCB swap but requires careful handling of the unit's aesthetics:

  • Faceplate Removal: You must remove the front magnesium alloy faceplate to access the mounting screws for the board.

  • Encoder Alignment: When re-installing, ensure the rotary encoder shaft is perfectly centered in the faceplate opening before tightening to prevent the knob from rubbing or sticking.

  • Ribbon Cable Safety: The cable connecting this board to the Main PCB is sensitive to electromagnetic interference; ensure it is routed along its original path and seated firmly in its ZIF (Zero Insertion Force) connector.

  • LCD Protection: During the swap, be careful not to touch the surface of the LCD or the inside of the acrylic window to avoid trapping fingerprints or dust that will be illuminated by the backlight.
