Product Overview
The RGB Spectrum Zio2 S5042 is a four-channel AV-over-IP encoder endpoint that captures four HDMI 2.0 sources and publishes multiple IP streams from a single enclosure. It is the highest-density member of the Zio S5000 series encoder line and is specified for control rooms, command centers and operations centers where many fixed sources are captured from one rack position. RGB Spectrum publishes S5042 input and output resolution as up to 1920 x 1200 @ 60 Hz. A local HDMI 2.0 monitor output and PoE++ compliance make the unit straightforward to commission in an equipment rack.
Product Description
Consolidating four encode channels into one 1.62 x 8.64 x 7.67 inch chassis reduces device count, switch ports and rack space against four single-channel encoder endpoints, which matters in a head-end that captures many operational sources continuously. Streams are published as H.264 or H.265 over RTSP with multicast transport, and the S5000 series streaming capability is published as multiple streams. Network connection is one RJ-45 gigabit port with an SFP position published for future use.

Audio can arrive embedded in HDMI or on the analog input and is carried embedded in the outgoing IP video stream. The RS232 connector is published for internal use only, so device control is planned around the network interface. Operators use a browser-based HTML5 application on Windows, macOS, iOS and Android, and UMP is available where the encoder must be driven from a wider control platform. Matching decode positions are covered by the Zio D2112 decoder endpoint at the same published resolution, or the Zio D2114 decoder endpoint where a 4K output path is required. Where resolution matters more than channel count, the Zio2 S5024 encoder provides two 4K channels, and the S5022 model is the two-channel 2K variant. Rack installation uses the 920 12293 rack shelf kit, supplied for Zio 2 and QV/SV IPX units. Specified this way, the S5042 gives a project the highest encode density in the Zio2 endpoint range.
Key Features
- Four HDMI Encode Channels — RGB Spectrum publishes 4x HDMI 2.0 input channels for the S5042, giving the highest encode density in the S5000 series.
- Multiple Stream Publishing — Published streaming capability is multiple streams, so a single unit can serve several independent decode destinations.
- 1920 x 1200 Capture — Published input and output resolution is up to 1920 x 1200 @ 60 Hz, which suits the 16:10 workstation sources common in operational rooms.
- Reduced Rack Footprint — Four channels in a 1.62 x 8.64 x 7.67 inch chassis frees rack space and switch ports compared with four separate encoders.
- Local HDMI Monitor Output — A 1x HDMI 2.0 output allows on-site confirmation of captured sources without opening a control application.
- PoE++ or 12 VDC Power — The unit is published as PoE++ compliant and rated 12 VDC, 65 W, so the rack position can be powered either way.
- H.264 and H.265 Compression — Codec choice lets the design balance total stream bandwidth against image quality across four channels.
- UMP and Browser Control — Browser-based HTML5 control covers day-to-day operation while UMP supports programmatic integration with a control system.
Typical Applications
- Control Room — Four operator or sensor sources are published from one rack position, keeping the head-end compact.
- Command Center — High encode density suits rooms where many fixed feeds must be available to every operator at once.
- Operations Center — Continuous capture of several sources is consolidated into a single managed endpoint.
- Broadcast Studio — Multiple program, preview and monitoring feeds are encoded together and distributed over the facility network.
- Government Space — UMP control lets the encoder be operated from an existing command and control platform.
- Training Room — Instructor, document camera and playback sources are captured from one enclosure and decoded at student displays.

Frequently Asked Questions
How many sources does the S5042 encode?
RGB Spectrum publishes 4x HDMI 2.0 input channels for the S5042. Two-channel alternatives are the Zio2 S5022 at up to 1920 x 1200 and the Zio2 S5024 at up to 4096 x 2160.
What is the published resolution?
Input and output are published at up to 1920 x 1200 @ 60 Hz for the S5042. If 4K capture is required, specify the Zio2 S5024 encoder instead.
Which decoders receive the streams?
The Zio D2112 decoder endpoint matches the published output resolution, and the Zio D2114 decoder endpoint is used where a display position needs a 4K decode path.
How much network capacity should be planned?
Four channels publishing simultaneously will consume more bandwidth than a single-channel endpoint. The unit provides one RJ-45 GigE port; plan multicast and switch capacity around the codec and stream count you configure.
How is the encoder rack-mounted?
Use the 920 12293 rack shelf kit for Zio 2 and QV/SV IPX units. Zio 2100 series endpoints use the Zio RAK 6RU rackmount shelf.
Can it be controlled from an existing AV control system?
Yes. Published control options are browser-based HTML5 for Windows, macOS, iOS and Android, plus UMP for programmatic integration.
What warranty and support apply?
The RGB Spectrum manufacturer warranty applies to this part number. Creation Networks supports specification, configuration review and procurement, and can route warranty and technical support requests to RGB Spectrum.
