3. Performance Specifications
3.1 Signal Processing Performance
• Video Signal Support: Supports HD resolutions up to 1920×1080@60Hz; compatible with mainstream resolutions; supports 16-bit true color display with no motion blur or latency
• Signal Switching Latency: Single-port switching response time ≤ 50 ms; multi-port polling switching interval ≤ 100 ms, ensuring real-time server management operations
• Signal Compatibility: Supports keyboard and mouse signals via both PS/2 and USB protocols; automatically identifies host signal types without the need for manual switching
3.2 Transmission Stability
• Transmission Reliability: Signal transmission bit error rate (BER) via CAT5 ports ≤ 10⁻⁹, meeting the requirements for long-term, uninterrupted operation
• Environmental Adaptability: Operating temperature 0°C–50°C, storage temperature –20°C–60°C, operating humidity 10%–80% RH (non-condensing); no signal loss or system crashes in high-temperature, high-humidity environments
• Power Supply Stability: Supports a wide input voltage range (DC 11.4 V–12.6 V); automatically stabilizes voltage during fluctuations to prevent motherboard reboots caused by unstable power supply
3.3 Management Functions
• Port Control: Supports three control modes—manual switching, automatic polling, and fixed-point switching—which can be triggered via the control terminal or the device’s buttons
• Status Monitoring: Monitors the connection status of CAT5 ports, the motherboard’s operating voltage, and chip temperature in real time; triggers indicator light alarms and records error codes when abnormal conditions are detected
• Firmware Upgrade: Supports online firmware upgrades via the RS232 serial port or USB port; device configurations are preserved during the upgrade process to ensure support for future functional updates
4. Compatibility and Adaptability Features
4.1 Unit Compatibility
• Compatible Models: Directly compatible with 8-port, 16-port, 24-port, and 32-port CAT5 KVM switches. The motherboard dimensions match standard 19-inch rack-mount KVM enclosures, supporting tool-free, quick replacement
• Module Compatibility: Fully compatible with the company’s proprietary CAT5 connection modules and compatible with connection accessories from mainstream CAT5 KVM switch brands, offering high versatility
4.2 Host Compatibility
• Operating Systems: Supports mainstream operating systems including Windows 2000/XP/7/10/11, the Windows Server series, Linux (Red Hat, CentOS, Ubuntu, etc.), and Sun Solaris
• Server Types: Compatible with servers from leading brands such as Lenovo, Sugon, Inspur, Huawei, HP, and IBM
4.3 Cable Compatibility
• Supported Cables: Standard CAT5/CAT5e unshielded/shielded twisted-pair cables; pure copper cables (wire diameter 0.45–0.51 mm) are recommended; compatible with both T568A and T568B wiring standards
5. Electrical Characteristics
• Operating Power Consumption: ≤5W (power supply for the entire unit, including the motherboard and peripheral control circuits); low-power design reduces overall data center energy consumption
• Standby Power Consumption: ≤0.5W; supports low-power standby mode, suitable for 7×24-hour uninterrupted operation
• Protection Features: Built-in overcurrent protection, overvoltage protection, and short-circuit protection; automatically cuts off power to the motherboard in case of abnormal conditions to prevent damage to the entire unit
6. Quality and Warranty
• Quality Standards: Motherboards undergo 100% functional testing (signal transmission, port switching, anti-interference, and stability tests) before shipment, with a 100% pass rate
• Factory Inspection: Comprehensive testing covering soldering quality, interface continuity, signal bit error rate, temperature adaptability, and other aspects to ensure fault-free products upon shipment
• Warranty Period: A 3-year manufacturer’s warranty is provided. During the warranty period, products with non-human-induced damage (such as component failure, motherboard short circuits, or signal transmission faults) will be replaced or repaired free of charge
• Technical Support: 7×24-hour technical support is provided, including motherboard troubleshooting, firmware upgrade guidance, and compatibility debugging services, to ensure operational efficiency
7. Packaging and Labeling
7.1 Packaging Specifications
• Single Motherboard Packaging: Anti-static vacuum bag containing 1 motherboard
7.2 Product Labeling
• Surface Silkscreen on Motherboard: Product model (e.g., KVM-CAT5PCB.V1.2)
8. Precautions
1. Motherboard installation and maintenance must be performed by qualified technical personnel, strictly adhering to anti-static and anti-short-circuit guidelines to prevent accidental damage
2. Do not plug in or unplug cables from the CAT5 ports or power ports while the motherboard is powered on, to prevent signal surges or short circuits that could burn out motherboard components
3. The motherboard must be stored in a dry, well-ventilated environment free of corrosive gases to prevent moisture and corrosion from causing circuit oxidation.
4. Do not modify the motherboard’s circuit design or upgrade to unofficial firmware without authorization, as this will affect the device’s compatibility and stability and is not covered by the warranty.
5. When the device is scrapped, it must be disposed of in accordance with electronic waste regulations.
