The **SES-2H1-R** is an industrial-grade **High-Definition Video Switcher/Splitter** component typically used in pro-AV (Audio/Visual) installations, broadcasting, and security monitoring. It is designed to manage high-speed digital signals with high reliability. --- ### Technical Specifications The following table outlines the primary electrical and physical characteristics of the SES-2H1-R: | Feature | Specification | | :--- | :--- | | **Interface Type** | HDMI / DVI compatible | | **Input Channels** | 2-Channel High Definition | | **Output Channels** | 1-Channel (Switchable) | | **Maximum Resolution** | 1080p @ 60Hz / 1920x1200 | | **Bandwidth** | 2.25 Gbps per channel | | **Power Supply** | 5V DC (External) | | **Control Method** | IR Remote, Push-button, or RS-232 | --- ### Key Electronic Components The internal architecture of the SES-2H1-R consists of several critical electronic stages: #### 1. Signal Equalization & Re-clocking To maintain signal integrity over long cable runs, the device uses **Active Equalizer ICs**. These chips compensate for high-frequency loss and reduce jitter, ensuring the digital "eye pattern" of the HDMI signal remains open and readable by the display. #### 2. HDCP Management The unit contains an onboard **EEPROM and Logic Controller** dedicated to HDCP (High-bandwidth Digital Content Protection) handshaking. This ensures that encrypted content from a Blu-ray player or PC is correctly authenticated before being passed to the monitor. #### 3. Power Regulation Circuitry Since the device handles sensitive digital signals, it employs **Low-Dropout Regulators (LDOs)** and decoupling capacitors. These components filter noise from the 5V DC input to prevent "sparkles" or video artifacts caused by electrical interference. #### 4. Switching Matrix The core is a **High-Speed CMOS Digital Switch**. Unlike mechanical switches, this solid-state component allows for "seamless" or "near-seamless" transitions between inputs without mechanical wear or significant signal degradation. --- ### Typical Application Diagram ```mermaid graph LR A[Source 1: PC] -->|HDMI| C{SES-2H1-R} B[Source 2: Camera] -->|HDMI| C C -->|Output| D[Projector/Monitor] E[IR Remote] -.->|Control| C ``` ---
