The **B112-002-R** is a 2-Port VGA/SVGA Video Splitter manufactured by Tripp Lite (Eaton). Below is a detailed breakdown of its electronic components, specifications, and internal functions. --- ## 1. Core Technical Specifications This device is an active electronic component designed to take a single analog video signal and replicate it across multiple outputs without signal degradation. | Feature | Specification | | :--- | :--- | | **Input Interface** | 1 x HD15 (VGA) Male | | **Output Interface** | 2 x HD15 (VGA) Female | | **Max Resolution** | 1920 x 1440 @ 60Hz | | **Bandwidth** | 350 MHz | | **Max Cable Distance** | Up to 210 ft (64 m) | | **Power Supply** | External DC Power Adapter | --- ## 2. Key Electronic Components The "R" in the model number typically signifies a retail-ready version of this active splitter. Unlike passive "Y-splitters," this unit contains active circuitry to maintain signal integrity. ### A. Internal Signal Amplifiers Because splitting an analog signal across two ports naturally leads to a drop in voltage (brightness/clarity), the B112-002-R contains **Operational Amplifiers (Op-Amps)**. These components: * Boost the incoming Red, Green, and Blue (RGB) signals. * Compensate for signal loss over long cable runs (up to 210 feet). * Ensure the impedance remains at a constant 75 ohms. ### B. Bandwidth Management With a **350 MHz bandwidth**, the internal circuitry is designed to handle high-frequency data. This prevents "ghosting" or blurring that occurs when high-resolution signals are pushed through low-quality components. ### C. Power Regulation The unit requires an external power source (usually 9V or 5V DC). Internally, it features: * **Voltage Regulators:** To provide a steady current to the amplification chips. * **Capacitors:** For filtering electrical noise from the power supply, ensuring a "clean" image. --- ## 3. Signal Flow Diagram The electronic path follows this logic: ```mermaid graph LR A[VGA Source] --> B[Input HD15 Port] B --> C[Internal Signal Buffer/Amp] C --> D[Port 1 Output] C --> E[Port 2 Output] F[DC Power In] --> C ``` --- ## 4. Usage Requirements * **Active vs. Passive:** This is an **active** device. It will not function without the power adapter because the internal transistors and amplifiers need electricity to mirror the signal. * **EDID Limitations:** Like most basic VGA splitters, the electronic handshake (DDC/EDID) is usually pulled from **Port 1**. The source computer will "see" the monitor on Port 1 and set the resolution based on that device.
