Digi EX12
Avoid Network Outages with Primary or Backup LTE Connectivity. Redundant, Carrier-Certified Cellular Access – Integrated Seamlessly.
The Digi EX12 provides uninterrupted connectivity via a carrier-certified LTE Cat 4 modem with dual SIM slots for automatic carrier failover and redundancy using Digi SureLink®. It integrates easily with wireline ISPs, dual-WAN appliances, or Ethernet devices, acting as a cellular extender for POS systems, ATMs, kiosks, digital signage, and more. Features Digi TrustFence® for built-in security (FIPS 140-2 compliant), Carrier Smart Select™ for automatic carrier switching, and centralized management via Digi Remote Manager (included in Digi 360 solution). Compact plastic enclosure suits indoor deployments; optional Remote Mounting Kit enables flexible placement with passive PoE for optimal signal.
Digi EX12 is an affordable, scalable failover solution that enables you to retrofit your infrastructure for advanced cellular network access. With a 3GPP-compliant, carrier-certified LTE Cat 4 cellular modem supporting multiple LTE bands and equipped with dual SIM slots, Digi EX12 provides uninterrupted primary or backup connectivity. It’s easy to deploy and is centrally managed via Digi Remote Manager (Digi RM), which is included in your Digi 360 solution.
The Digi EX12 enterprise cellular extender with advanced routing capabilities protects against downtime by automatically switching to a secondary cellular carrier should the primary SIM lose Internet access. This compact, high-performance device is also compatible with any dual-WAN networking appliance and helps you achieve reliable connectivity at any location using your existing equipment.
Couple the Digi EX12 with a dedicated wireline ISP connection to maximize uptime and ensure reliable network availability for POS systems, ATMs, mobile kiosks, digital signage and more. Deployments are streamlined with installation accessories including an optional Remote Mounting Kit for site survey, mounting bracket and a passive PoE injector for optimizing placement for the best cellular reception.
Part of Digi enterprise solutions, this extender comes with industry-leading software, including Digi Accelerated Linux (DAL OS), Digi TrustFence security framework, and the Digi RM configuration and management platform. These tools deliver security, reliability and system-wide management of your entire infrastructure for centralized control, management, security, edge intelligence and day-to-day network management for hundreds and thousands of distributed devices. Digi RM lets you evaluate, update and configure your Digi routers and extenders — and the health of your network — at scale, after deployment.
