Yes, many serial servers are equipped to support Ethernet connectivity. These devices act as converters, allowing serial devices to communicate over an Ethernet network. This is particularly useful for industrial or commercial applications where older serial equipment needs to be integrated into an existing IP-based system. A robust serial server facilitates this integration, providing a reliable bridge between different communication protocols. This also enables remote management and access to serial devices from anywhere on the network, enhancing operational efficiency and flexibility.
By utilising a serial server, businesses can extend the lifespan of their existing serial infrastructure while benefiting from the advantages of Ethernet networking, such as higher speeds and greater distances. Rugged Limited offers solutions that cater to these specific connectivity needs.
Yes. Digi’s cellular range spans LTE through to 5G, with several FirstNet-capable models for public-safety and critical-infrastructure use. The IX40-05 supports 5G NSA, 5G SA and LTE-Advanced Pro Cat 19 across 5G NR n1 to n79 including CBRS and C-band, with B14 FirstNet among its 4G bands, while the EX50 delivers 5G NR Sub-6 GHz with 4G and 3G fallback and Wi-Fi 6. The LTE Cat 4 IX30-0EG4 is also FirstNet-capable and adds Anterix B8 for private LTE on 900 MHz. Many models include GNSS for location services. Band support, carrier approvals and FirstNet readiness are strictly model-dependent, so confirm the exact configuration on the relevant product page before ordering.
Across the Digi catalogue on rugged.co.uk, the recurring sectors are energy and utilities, industrial manufacturing, construction, logistics and supply chain, retail, security and surveillance, healthcare and the public sector. The hardware tends to be specified for SCADA, smart grid, critical infrastructure, remote site monitoring, asset tracking, digital signage and industrial HMI applications. Cellular routers such as the IX and EX series suit unattended and outdoor sites; Connect EZ serial servers target industrial automation, manufacturing and healthcare where legacy serial devices must reach IP networks; and AnywhereUSB hubs serve broadcast, data centres and control rooms. Because each product is rated and certified differently, match the specific model to your operating environment and confirm temperature range, ingress protection and approvals on the product page.
Several Digi cellular routers are built for harsh and regulated environments, though the exact ratings differ by model. The IX30-0EG4, for example, carries an aluminium IP30 enclosure with hazardous-location approvals including ANSI/ISA 12.12.01 Class 1 Division 2, ATEX II 3 G Ex nA IIC T4 Gc and IECEx, plus a NEMA TS2 temperature rating from -34 C to 74 C for traffic cabinets and utility enclosures. The IX40-05 flagship operates from -40 C to 75 C in a glass-filled PPS chassis rated IP30. Many models add wide-input DC power and DIN-rail mounting for cabinet installation. Because certifications and temperature ranges are model-specific, check the relevant product page before specifying for a hazardous or outdoor deployment.
Digi Remote Manager is Digi’s cloud platform for provisioning, monitoring and securing fleets of deployed devices from a single dashboard. It is referenced across the Digi range on rugged.co.uk, from IX and EX cellular routers to Connect EZ serial servers and AnywhereUSB hubs, and supports configuration, firmware updates, alerts and intelligence at scale. For operators running hundreds of remote or unattended sites, this matters because it removes the need for engineer site visits to push updates or diagnose faults. Many devices pair it with the Digi 360 subscription, which on routers such as the IX40-05 bundles Remote Manager, warranty and 24/7 support for the first year. Confirm the exact management bundle and SNMP options on each product page.
Digi builds security into its connectivity platform through Digi TrustFence, which provides secure boot, encrypted connections and device authentication. It appears across the range, including the Connect EZ serial device servers and IX-series routers. Several models add FIPS 140-2 cryptography, for example the IX40-05, and support VPN tunnelling through IPsec with IKEv1 and IKEv2, OpenVPN client and server, and GRE, alongside stateful firewalls, MAC filtering and VLAN support. Authentication options include RADIUS, TACACS+ and certificate-based access. This layered approach suits critical infrastructure and SCADA deployments where the connection itself is part of the attack surface. As security feature sets vary between routers, serial servers and USB products, verify the specifics on the individual product page.
Digi Connect EZ serial device servers exist to connect legacy serial equipment to modern IP networks without replacing the underlying machinery. The range on rugged.co.uk runs from single-port units up to the eight-port EZ08-TS00, with software-selectable RS-232, RS-422 and RS-485 on each port. A key feature is Digi RealPort, which lets remote serial devices appear as native COM ports on a host system, simplifying integration with existing applications. They support serial tunnelling, TCP and UDP, a built-in Python environment for edge scripting, and TrustFence security. Typical uses are industrial automation, manufacturing, healthcare and control rooms. Some variants add LTE, Wi-Fi or industrial temperature ratings, so confirm port count, interfaces and environmental specs on the product page.
Digi AnywhereUSB is a USB-over-IP solution that lets you attach USB devices remotely across an Ethernet network rather than plugging them directly into a host PC. The PLUS range on rugged.co.uk scales from 2 up to 24 ports, with the AW24-G300 AnywhereUSB 24 PLUS offering 24 USB 3.1 Gen 1 Type A ports plus dual 10G Ethernet and SFP+ for high-availability networking. By placing the host computer in a secure, sealed location away from the USB peripherals, it removes cable-length constraints and protects computing equipment from harsh conditions. Management is via web UI and cloud-based Digi Remote Manager. It suits broadcast, industrial, healthcare and data-centre deployments. Port counts, Ethernet speeds and ratings differ across models, so check the product page.
Digi International is a US manufacturer focused on industrial IoT and cellular connectivity, supplying the kind of infrastructure that keeps unattended and remote sites online. On rugged.co.uk its catalogue spans three main families: cellular routers (the IX and EX series, including 5G models such as the IX40-05 and EX50), Connect EZ console and serial device servers that bridge legacy RS-232, RS-422 and RS-485 equipment onto IP networks, and AnywhereUSB hubs that extend USB ports over the network. The common thread is reliable connectivity for critical infrastructure, SCADA, smart grid and edge computing applications, backed by cloud orchestration through Digi Remote Manager. Always confirm bands, ports and ratings on the individual product page, as specifications vary by model.
