Kramer K248E HighSecLabs Secure 8-Port, Dual Display DVI-I KVM Switch

Meet the Kramer K248E, a premium secure KVM switch engineered for demanding environments where isolation, reliability, and high-performance multi-monitor control matter. This HighSecLabs-certified device connects eight separate computers and delivers true dual-display control through DVI-I, with compatibility for VGA, DVI, and HDMI video interfaces. Designed to maximize security in data centers, government facilities, and research labs, the K248E keeps each connected system isolated while enabling fast, seamless switching between machines. Whether you’re consolidating workstation access for security-conscious teams or providing robust console control in a secure rack, the K248E empowers administrators to manage multiple hosts from a single keyboard, video monitor set, and mouse setup while preserving the integrity of each endpoint.

• Secure, scalable control — Eight independent host connections allow you to manage up to eight computers from one secure console, with strong isolation between every connected system to minimize risk of data leakage or cross-contamination.
• Dual-display per host — Each computer can drive two video outputs, enabling true dual-monitor setups that boost productivity, enhance monitoring, and simplify complex workflows across the network of hosts.
• Broad video interface support — Video ports accommodate a wide range of interfaces, from legacy VGA to modern HDMI, including dual-link DVI. This versatility makes the K248E compatible with a broad spectrum of workstations and displays without requiring frequent hardware changes.
• HighSecLabs-secured architecture — Built to meet strict security requirements, the K248E provides robust isolation between connected systems, helping organizations maintain secure, auditable operation in sensitive environments.
• Easy, reliable switching — Front-panel controls and intuitive switching options (with keyboard/mouse sharing) enable rapid, reliable switching among up to eight hosts, supporting efficient workflows in busy laboratories, control rooms, and secure workstations.

How to install Kramer K248E

• 1. Plan your layout — Determine which eight computers will connect to the K248E and identify the two video outputs per computer. Prepare two displays or a dual-monitor configuration for the shared console.
• 2. Power down — Turn off all computers, displays, and any peripheral devices to prevent hot-plug issues during installation.
• 3. Connect video inputs — For each host, connect its video outputs to the K248E’s corresponding video input ports. Ensure that the primary and secondary displays are routed to the correct inputs so you can drive both monitors from each host.
• 4. Attach displays — Connect the two monitors to the K248E’s display outputs or to the designated monitor paths on the unit, ensuring correct alignment with your dual-display plan.
• 5. Attach keyboard and mouse — Connect a USB keyboard and USB mouse to the K248E’s console ports so you can operate and switch between hosts from a single control surface.
• 6. Power and test — Apply power to the K248E and each connected PC. Use the front-panel controls or configured hotkeys to verify that you can switch between hosts and that both displays show the correct output for each computer.

Frequently asked questions

• Q: What is the Kramer K248E best used for? A: It’s ideal for secure environments that require centralized console control of multiple computers with dual-monitor capabilities, such as data centers, government facilities, labs, and security-conscious workstations.
• Q: How many computers can I connect? A: Up to eight different computers can be connected to the K248E, each with access to two video outputs for dual-monitor operation.
• Q: What video interfaces does it support? A: The K248E supports a range of interfaces on its video ports, including VGA, DVI-D (supporting dual-link), and HDMI, ensuring compatibility with a broad mix of displays and workstation GPUs.
• Q: Is the isolation between hosts strong enough for secure environments? A: Yes. The HighSecLabs certification ensures consistent, robust isolation between connected hosts, helping to preserve data integrity and minimize cross-system risk.
• Q: How do I switch between hosts? A: You can switch using front-panel controls on the K248E or via hotkey sequences from the connected keyboard, enabling fast, seamless transitions between machines without leaving the console.
• Q: Do I need specific firmware or drivers? A: The K248E is designed for straightforward plug-and-play operation with standard USB keyboards/mice and display interfaces. No special drivers are typically required beyond general peripheral support.
• Q: Can I use different display resolutions on each monitor per host? A: Yes. Because each host provides two video outputs, you can configure different resolutions or displays per monitor according to the host’s capabilities and your display chain.
