A 3G-SDI routing switcher operates at signal rates up to 2.97 Gbps — supporting HD and some 4K signals, but requiring four separate 3G signal paths (Quad Link) to carry a full 4K UHD signal. A 12G-SDI routing switcher operates at up to 11.88 Gbps, allowing a single coaxial cable to carry 4K UHD over a single link. Utah Scientific's UHD-12G is the industry's first enterprise-class router to handle data rates from SD up to 2160p60 over a single-link interconnect — eliminating the multi-path cabling complexity of 3G routers for UHD production. For facilities handling 4K content, a 12G-SDI routing switcher reduces cable runs, rack space, and operating expenses while simplifying signal management.

Yes. Utah Scientific SDI routers are built around multi-rate signal architectures. The UHD-12G routing switcher supports data rates from 18 Mbps through 12 Gbps on the same I/O cards — meaning SD, HD, 3G, and 12G-SDI signals can all be routed within the same chassis without dedicated cards per format. The UTAH-400 Series 2 also supports simultaneous operation of SD, HD, 3G, and IP signal formats within the same frame. Automatic reclocking applies to all standard signal rates, with automatic bypass for non-standard rates — so the router adapts to whatever signal is present without manual reconfiguration.

Both are enterprise-class SDI routing systems backed by Utah Scientific's no-fee 10-year hardware warranty — but they serve different primary use cases.

The UHD-12G is purpose-built for 12G-SDI single-link UHD routing — ideal for facilities handling 4K content where minimising cabling and rack space is a priority. It scales from 32×32 to 288×288.

The UTAH-400 Series 2 is a broader signal management platform that handles SDI, ASI, HD, 3G, analog, fiber, AES, MADI, and — via PassThrough cards — SMPTE ST 2110 IP signals, all in a single frame. It scales from 72×72 to 1056×1056, making it the preferred choice for large enterprise facilities, NOCs, and broadcast hubs with complex signal environments. Both are compatible with Utah Scientific's SC-4, SC-40, and SC-400 control systems.

All Utah Scientific SDI routers — including the UDS Compact Series, UHD-12G routing switcher, and UTAH-400 Series 2 — are compatible with the SC-4, SC-40, and SC-400 hardware control systems. The UTAH-400 Series 2 also supports NMOS IS-04 and IS-05 control for IP-based workflow orchestration, allowing SDI crosspoints and IP flows to be managed from the same control plane. The UDS Compact Series includes a native internal web server that operates on standard browsers with no additional software download required. This universal control system compatibility means facilities can scale from a compact UDS installation to a full enterprise Series 2 deployment without replacing their control infrastructure.

SMPTE ST 2022-6 defines how uncompressed SDI signals are transported over IP networks as high-bitrate media packets — sometimes called "SDI over IP." It is one of the transitional standards that facilities adopt before moving to SMPTE ST 2110, which separates video, audio, and ancillary data into independent IP streams.

The UTAH-400 Series 2 supports IP decoding and multiplexing of both ST 2022-6 and ST 2022-8 via advanced modules within the router frame — allowing facilities to handle SDI-over-IP workflows alongside traditional SDI routing without external conversion hardware. For full SMPTE ST 2110 support with native encapsulation and de-encapsulation inside the chassis, the UTAH-400 Series 2 Gateway Router is the recommended solution.

Yes — if you have an existing UTAH-400 Series 2 router, IP capability can be added incrementally using Utah Scientific's PassThrough cards, which slot directly into standard I/O card positions in the existing chassis. No chassis replacement is required, and the SDI routing fabric continues to operate as normal, providing a continuous fallback path if the IP side encounters any disruption.

For facilities on the UDS or UHD-12G product lines, the On-Ramp — a 1RU hybrid gateway device — connects to your existing router and provides ST 2110 encapsulation and de-encapsulation with five hot-swappable card slots and 16 SFP cages.

Utah Scientific's 10-year hardware warranty is the only warranty of its kind in the broadcast industry. It covers hardware defects and failures for a full ten years from the date of shipment — with no annual fees, no support contract required to access technical assistance, and no fine print. The warranty applies to the full hardware system: router chassis, cards, and control hardware. It is included with every Utah Scientific SDI router — UDS Compact Series, UHD-12G routing switcher, UTAH-400 Series 2, and UTAH-400 Series 2 Gateway Router. Customers have reported Utah Scientific routers running 24/7 for nine or more years without power supply failures, control failures, or the need to reboot.

The largest SDI routing frame available from Utah Scientific is the UTAH-400 1056XL, providing a 1056×1056 signal matrix. The Series 2 line scales across five frame sizes — 72×72, 144×144, 288×288, 528×528, and 1056×1056 — all sharing the same modular I/O card architecture and control system compatibility, allowing facilities to start at any size and expand without replacing chassis components. The UTAH-400 Series 2 Gateway Router, which adds embedded SMPTE ST 2110 gateway functionality, is available across the same range of frame sizes.

NMOS (Networked Media Open Specifications) IS-04 and IS-05 are open API standards from the Advanced Media Workflow Association (AMWA). IS-04 handles device and resource discovery — so the control system automatically identifies all available inputs, outputs, and devices on the network. IS-05 handles connection management — defining how those resources are routed and switched.

The UTAH-400 Series 2 and UTAH-400 Series 2 Gateway Router both support NMOS IS-04 and IS-05, allowing SDI crosspoints and ST 2110 IP flows to be managed from the same NMOS-compliant software controller — eliminating the need for separate control environments for SDI routing and IP networking.
