The IP25-R is housed in a durable aluminum enclosure, ideal for both portable “throw-down” use and high-density rackmount installations. Up to three units can be mounted side-by-side in a single 1RU shelf—perfect for space-constrained environments. With AJA’s DRM2-Plus 3RU rackmount frame, redundant power can be provided for up to six IP25-Rs! 

For fast setup, the front-facing USB-C port supports AJA’s free eMini-Setup application for easy initial network configuration. Multicast setup, internal routing, and output specific functions are accessed via the WebUI. Designed with active front-to-back cooling, the IP25-R ensures reliable, long-term performance in demanding broadcast and production locations. 

The IP25-R now supports SDI to ST 2110 (Tx) signal conversion. You can convert up to 4x SDI signals into ST 2110 with support up to 12G-SDI, making this device the most flexible converter on the market. To ensure the signal integrity of the baseband to IP conversion, each ST 2110 and HDMI output has an optional Frame Sync with delay capability to ensure signals arrive when they are supposed to. When the ‘Timing’ slider is enabled, Frame Sync is activated and when the ‘Timing' button is selected, the Configure tab on the right will show the status and functions. ‘Input To Output Delay’ shows the input routed to the selected output pipeline. It also shows the input timing offset, relative to PTP. This is presented as H+V time, Frame Time, and Total Time (in ms).

The IP25-R is not only a standout performer when it comes to video processing and configuration but also includes powerful audio capabilities to ensure maximum flexibility in production situations.  

Audio Mapping: 

New in v2.0 firmware is the ability to provide multi-audio stream mapping per video channel, supporting options between 1x16, 2x8, and 4x4 for interoperability with industry standard audio configurations. Also, ‘Audio Follows Video’ is now enabled by default for ease of use. 

Audio Delay: 

The IP25-R provides adjustment of audio timing in ms. When video is delayed, the same delay is applied to audio and presented as 0ms. 0ms delay is in relation to the video. 

Each ST 2110 output can have an individual test signal enabled and set. This provides the capability to generate up to 4 individual ST 2110 test signals (bars, flat field, black, etc) with the option to enable a 1KHz tone as well. These signal generators are important tools for setting up and checking ST 2110 signal paths. The test pattern includes an optional on-screen overlay with the device hostname, time-of-day, and RJ45 control IP address, so the video output becomes a live “label” for the unit. If the WebUI isn’t reachable, and you need to start your network setup or troubleshooting, you can double-press the reset button to toggle the test pattern on, then double-press again to return to normal output. 

Network Validation – Ping: 

• Ping a target IP directly from IP25-R per interface (control, media 1, media 2). Quickly confirm reachability when discovery and control aren’t behaving as expected — especially critical in multi-network facilities. 

PCAP – Packet Capture File: 

• PCAP provides capability to capture stream (Ethernet/IP packets) data on all network interfaces at once for troubleshooting. Once captured, the file can be downloaded to your computer and opened with Wireshark.

SDP (Session Description Protocol) File Override: 

• Temporarily ignore specific SDP fields to prove whether media is present and isolate where the issue is — then restore standard behavior once resolved.

NMOS Flexible Discovery Modes: 

• Control how IP25-R searches for and connects to NMOS services across control vs media networks. Support for DNS-SD + mDNS and static registry IP options to align with your facility configuration. 

Operational Statics: 

• Visibility into Rx/Tx bitrate, corrupt packets, and FEC errors, with counter resets for before/after validation. 

In this workflow, you see the new Tx mode whereby 4 HDR HD-SDI camera feeds are simultaneously converted to SMPTE ST 2110. The local HDMI ports can be used for confidence monitoring of the camera feeds.

In this IP-based stadium example, live camera feeds and the video switcher connect to redundant SMPTE ST 2110 network switches, which deliver synchronized IP video, audio, and metadata directly into the IP25-R's dual SFP inputs for seamless ST 2110 reception and conversion.

• 2x HDMI 2.0 outputs feed directly to 2x HDMI monitors, up to 4K 4096x2160p.

• SDI 1 output feeds in the AJA ColorBox (or OG-ColorBox) for color verification. The ColorBox then distributes the signal via SDI and HDMI to monitors.

• SDI 2, 3, and 4 outputs directly to SDI monitors.

The IP25-R enables seamless conversion of uncompressed SMPTE ST 2110 UHDp60 (3840x2160) video to your existing on-site SDI infrastructure. In this setup, the converted ST 2110 signals are routed through an AJA KUMO SDI router, allowing flexible signal distribution throughout your facility. For added assurance, the IP25-R features dual HDMI outputs, ideal for real time signal confidence monitoring in machine rooms or engineering environments.

• Rx 1 routes internally to SDI 1 and HDMI 1. SDI 1 feeds into the router for wider signal distribution, and HDMI 1 is used for confidence monitoring.

• Rx 2 routes internally to SDI 2 and HDMI 2. SDI 2 feeds into the router for wider signal distribution, and HDMI 2 is used for confidence monitoring.

Easily display SMPTE ST 2110 UHDp60 Multiviewers through the two HDMI 2.0 outputs while routing them through your existing SDI infrastructure using the IP25-R and KUMO router. This workflow enables real time multi-viewer monitoring in your control rooms and easy SDI distribution, providing a seamless bridge from IP-based video to traditional baseband environments.

• Rx 1 routes internally to HDMI 1, which then outputs to an HDMI monitor. It also routes to SDI, which feeds into the KUMO router and SDI infrastructure.

• Rx 2 routes internally to HDMI 2, which then outputs to an HDMI monitor. It also routes to SDI, which feeds into the KUMO router and SDI infrastructure.
