Across many industrial sectors, control rooms are responsible for monitoring and managing critical processes. Those in remote, space-constrained, or physically harsh environments face unique challenges. For example, in the oil and gas industry, control rooms monitor production, refining, and distribution throughout complex pipeline systems in remote facilities. In chemical processing plants, process and machine control equipment must operate safely and reliably in the presence of volatile substances. Harsh environments in every sector can make it challenging for computers and operators to maintain secure, reliable connections.
When technology fails in these settings, the impact goes beyond inconvenience, leading to system downtime, operational disruptions, and/or significant financial consequences. A keyboard, video, and mouse (KVM) extender enables operators to work on a computer from a safe, remote location with reliable connectivity.
The Challenge: Computing at the Edge in Harsh or Hazardous Environments
Engineers and procurement teams for equipment in harsh environments must find reliable ways to keep servers protected inside enclosed, hazardous areas while still providing secure, long-distance connectivity to field computers and displays.
The Problem With Traditional Setups
In industrial sites, computers and servers are often located in environments with heat, dust, vibration, or explosive risk. Keeping full workstations in these zones is costly, risky, and maintenance-heavy. Because they’re designed for stable, climate-controlled settings, ordinary monitor and keyboard cables would be vulnerable to insulation degradation, physical damage, and corrosion in harsh environments.
The Growing Need for Remote Access
Engineers and operators require fast, real-time access in the field to sensitive equipment, including:
- Control systems
- Data displays
- Visualization software
Procurement teams need new and innovative ways to extend their computing capabilities without compromising latency or safety measures.
The Solution: What a KVM Extender Does
A KVM switch extender is a reliable and effective solution for overcoming the distance limitations of USB, HDMI, and DisplayPort™ cables. A KVM extender comprises two separate units:
- Transmitter (Tx). Connects to a computer system to capture peripheral signals (audio, video, mouse, or USB for an industrial computer keyboard).
- Receiver (Rx). Connects to devices from a remote location.
These components separate the input/output of the workstation from the server, using CATx or fiber cabling to transmit reliable signals over long distances. The signals are encoded using the Internet or a proprietary protocol and extended to a remote user station for decoding by the KVM receiver unit.
Safe Server Containment
A KVM extender enables the storage of critical servers in explosion-proof or climate-controlled enclosures, while the operator controls a remote console in the field.
Typical Range and Performance
Top-quality KVM extenders can effectively maintain real-time responsiveness by transmitting control and video signals from 15 feet to hundreds of meters away from the computer system. CATx cables made from copper can transmit signals up to 328 feet away, while fiber optic cables can transmit signals up to 25 miles away and are immune to EMI.
Benefits for Harsh and Hazardous Applications
KVM extenders offer a diverse range of benefits specifically for harsh and hazardous applications.
Safety and Compliance
KVM extenders support full compliance with industry regulatory standards, keeping sensitive electronics out of classified zones and maintaining full operational access. KVM extenders can also significantly reduce the risk of heat buildup or ignition sources in hazardous environments.
Reliability and Uptime
KVM extenders minimize environmental stress on sensitive components, making them easier to troubleshoot and maintain from a safe distance.
Performance Without Delay
Modern KVM extenders can effectively minimize latency so that video feeds and control systems respond instantly, which is crucial for safety and process monitoring systems.
Simplified Field Operation
Operators can work from safe, convenient, and remote locations without the need for ruggedized PCs at every station.
KVM Extenders From Daisy Data Displays
KVM extenders provide enhanced data protection, significantly reducing the repair and maintenance costs associated with operating IT equipment in harsh and hazardous environments.
At Daisy Data Displays, we offer a diverse selection of dedicated KVM extenders. Our standalone KVM extenders provide a variety of features and wide compatibility to meet your specific requirements. Unlike commercial-grade KVM extenders, our solutions are engineered to meet rugged and MIL-SPEC requirements, ensuring reliable long-term performance in extreme temperatures, high-vibration settings, and mission-critical applications.
For example, our 2445 series features a flip-up, slide-out LCD monitor drawer and keyboard with integrated KVMs, purpose-built for rugged aerospace and defense environments. By combining hardened design with proven field performance, we deliver solutions that maintain uptime and responsiveness.
Both the 2445 and 2123 series industrial monitors have built-in KVMs for maximum functionality. In one past project, we successfully integrated the 2123AA industrial monitor into an auto body shop to improve the batch accuracy and uptime of their paint mixing operation. Their existing commercial-grade PCs experienced frequent malfunctions in the mixing room, driving up costs and impacting batch accuracy. Our solution was to install the 2123AA monitor, pair it with a precision scale, and connect both devices to an off-site commercial PC using the 2123AA’s KVM extender.
Our KVM extenders are ideal for demanding environments that use industrial monitors to control batch production. KVMs can be integrated into our computers or used as add-ons. Key advantages of our KVM extenders include:
- Facilitating point-to-point computer extension
- Providing access to IT equipment from remote locations
- Transmitting secure connections over long distances
- Limiting lengthy processing delays from the server rack
KVM Extenders for Server Racks
KVM switches are used to control multiple computers or servers from a single workstation without requiring separate peripherals for each device. KVM extenders lengthen the physical distance of these operations, allowing users to control computers or servers far from their workstations. KVM extenders are especially useful in situations where physical proximity to the server is not easy or feasible, including industrial environments.
Daisy Data Displays offers the 5560 series to allow full operation of a computer or server with USB peripherals located as far away as 0.25 mile. With minimal processing delays, it supports all combinations of video cards, DVI-D monitors, and USB 2.0 transparent devices. Compatible with all major KVM switches and operating systems, the 5560 series comes with various options for mounting in a 19” rack.
