The Digi TX54-A146 is a complete Digi 360 solution package built around the Digi TX54, a rugged transportation and public-safety router engineered for transit vehicles, public-safety fleets, and fixed critical sites that demand carrier redundancy and rugged construction. Instead of buying hardware, management software, and support contracts separately, this single SKU delivers the router plus a one-year Digi 360 subscription that includes Digi Remote Manager, enhanced 24/7 technical support, and warranty coverage for as long as the subscription remains active. On the connectivity side, the Digi TX54 provides a FirstNet-capable LTE Advanced modem with four SIM slots for multi-carrier redundancy. dual-band Wi-Fi 5 (802.11ac) serves local clients without extra access-point hardware. GNSS supplies location data for tracking and compliance workloads. wired devices attach through quad gigabit ethernet. legacy equipment connects over the DB9M RS-232 port. This configuration is built for North America deployments. Digi Remote Manager gives network teams a single console to configure, monitor, and update every deployed unit, schedule firmware rollouts, and watch cellular health across the fleet. When the term ends, renewing the Digi 360 subscription keeps support and warranty coverage in force, making lifecycle budgeting predictable. With four SIM slots across its modem configurations, the TX54 line is built for agencies that treat connectivity as a life-safety service.
