The Close Relationship Between the DDM(Dynamic Device Mapping) and the Passthrough Mode of KVM Switch

DDM KVM.jpgIn the ever-evolving landscape of technology, the need for efficient and seamless connectivity between devices has become paramount. KVM switches play a crucial role in facilitating this connectivity, allowing users to switch between multiple systems effortlessly. One innovative technology that enhances this experience is Dynamic Device Mapping (DDM). TESmart, a leading provider of KVMs, integrates DDM into its KVM switches' Passthrough mode, elevating the compatibility of keyboards and mice while enhancing the overall user experience. 

Understanding DDM Technology

Dynamic Device Mapping, or DDM, is a cutting-edge technology employed in USB KVM switches as an alternative to standard USB keyboard and mouse emulation. Unlike traditional emulation methods, DDM ensures continuous communication between shared peripherals and all connected systems, maintaining a 100% connection even as users switch between KVM ports.

The Role of DDM in KVM Device Emulation

Traditional USB KVM devices often utilize peripheral emulation to send signals to computers not currently selected, simulating the presence of a connected keyboard, mouse, and monitor. This emulation is crucial for avoiding issues with machines that may reboot during unattended operation. However, it comes with limitations and inconsistencies, especially when dealing with various types of I/O devices.
DDM takes KVM device emulation to the next level by eliminating the need for generic device emulation. With DDM, each connected computer system believes that all I/O devices remain connected, even when the KVM switch shifts to another port. This innovative approach ensures a seamless experience without the interruptions or inconsistencies associated with traditional emulation methods.

Enhanced User Experience with Passthrough Mode

TESmart's KVM switches incorporate a Pass-through mode, a built-in feature primarily utilizing DDM technology. This mode significantly improves the compatibility of keyboards and mice, providing users with an experience akin to a direct connection to the computer. In Passthrough mode, users can enjoy a broader range of keyboard and mouse functionalities by connecting the keyboard and mouse to the dedicated keyboard and mouse ports, including special features not supported by traditional KVM switches.
At the USB protocol level, the Passthrough mode in TESmart's products ensures the transmission of authentic device descriptors to the computer. This guarantees that keyboards and mice connected to the KVM switch maintain the same functionality as when directly connected to the computer. In contrast to many other KVMs on the market, which simulate a USB Composite Device internally, TESmart's approach allows for seamless and full-functioning use of peripherals.
Switching between input source devices on TESmart's KVM switches does not result in the disconnection of the connected keyboard and mouse from any PC. The internal selector in the product ensures real-time transmission of USB data to the correct PC. This eliminates the inconvenience of frequent device disconnects and reconnects, enabling immediate use of keyboards and mice when switching between input source devices. It's a time-saving solution that enhances overall productivity.

TESmart's Product Recommendations with Pass-through Mode

Most of TESmart's products support Pass-through mode. There are two notable products:
1. TESmart 2 Port Dual-Monitor HDMI KVM Switch - HKS0202A2U: This switch supports dual monitors and features Pass-through mode with DDM technology. It ensures a smooth and uninterrupted experience, allowing users to switch between connected devices without any disruption to the keyboard and mouse, which are connected to the dedicated keyboard and mouse ports on the KVM.
2. TESmart 4 Port Dual-Monitor HDMI KVM Switch - HKS0402A2U: With support for dual monitors and the innovative Pass-through mode, this KVM switch provides a high-quality display experience. Passthrough mode ensures that keyboards and mice maintain optimal functionality, offering users a hassle-free and efficient switching process.

Conclusion

Dynamic Device Mapping technology represents a significant leap forward in the realm of KVM switches. By ensuring continuous communication between peripherals and connected systems, DDM eliminates the drawbacks associated with standard device emulation. TESmart's integration of DDM technology in Pass-through mode redefines the KVM switch experience, ensuring compatibility, flexibility, and a seamless transition between connected devices.
