RDS Encoding and Monitoring

Product Overview

RDS E3 and RDS E5 are static/dynamic RDS Encoders supporting all the services and features requested by an advanced user.RDS E3 and RDS E5 support the most advanced RDS dynamic services, including TMC, ODA, IH, TDC, EWS, Radio Text and Radio Text plus.RDS E3 and RDS E5 manage up to 8 complete Data Set, each one with 1 Main PS and 10 EON. To assure the best flexibility, any Dataset can be managed via Standard Mode, using UECP commands or via Extended Mode using GPIOs, SNMP commands, REST API commands or ASCII commands.In addition to standard CENELEC NRSC methods, RDS programming has been enriched with larger PS and RT sets (that are also available in dynamic mode).RDS E3 and RDS E5 can interface with various Automation Systems and they offer an ASCII protocol for broadcast song/artist information. In case of alarms, they support SNMP alerting for NMS.

RDS Encoder RDS E3 AxelTech

RDS E3 and RDS E5 satisfy the high-end broadcasters’ requirements: UECP system features 4 TCP ports, 4 UDP ports, 2 serial ports and 1 SNMP port.RDS E3 and RDS E5 are RDS 2.0 Ready: they manage the 4 RDS subcarriers specified in the standard that is still under definition. A web interface has been created to control all these functions and it can be used by any browser with any device from the smartphone to the laptop.RDS E3 and RDS E5 are SNMP v2c in order to satisfy the most demanding deployments. RDS E3 and RDS E5 have an high resolution colour display that allows the display and insertion of the main machine parameters.

Special featuresBroadcast “All” Your Information

RDS E3 and RDS E5 are the result of the long-time AxelTech experience in RDS encoder development.RDS E3 and RDS E5 can simultaneously receive UECP commands through 4 TCP ports, 4 UDP ports and 2 serial ports, enabling the most demanding network operator to connect all the dynamic sources to the RDS encoder.In addition to the accurate use of the RDS through UECP commands, RDS E3 and RDS E5 enable the end user to benefit from more simple and flexible ways to send information to the encoder by offering: REST API commands, ASCII Parser and SAMBA connection to Radio Playouts.RDS E3 and RDS E5 can automatically get information from the Radio Playouts thus eliminating the need of Middleware Software between the Playout and the RDS encoder.

Opened To The Future

RDS E3 and RDS E5 are RDS 2.0 Ready. Their DSP can generate the multicarrier signal needed for the new RDS standard. Once this standard is defined, with a simple software upgrade the end user will be able to have a RDS 2.0 compliant encoder without any replacement that would vanify the initial investement.

Easy Access

RDS E3 and RDS E5 are fully configurable via WEB interface. Their web server is compatible with all the available web browsers (Chrome, Firefox, Edge, Opera, Safari etc.).RDS E3 and RDS E5 supports laptop, tablet and smartphones simplifying the browsing and setting of the device. They have a responsive-kind graphic interface that adapts the viewing mode according to the resolution and position (portrait/landscape) of the current viewing device.The provided WiFi USB dongle creates a specific WiFi hotspot that enables the access to the device without the need of cabled or wireless net.RDS E3 and RDS E5 have 3 IPV4 and 3 IPV6 addresses to ensure simultaneous connection to all the broadcasting and monitoring systems.

Easy Maintenance

Any first-time user can benefit from RDS E3 and RDS E5 simplified settings management.QUICK RDS SETUP is the easier way to set the main RDS parameters.IMPORT/EXPORT and PRESET MANAGER are available for RDS E3 and RDS E5’s advanced management.These functions can be used for the whole device configuration or only for some selectable modules (SYSTEM, RDS, and TUNER).RDS E3 and RDS E5 use a uSD card to create an automatic copy of all the device data when the user changes anything. If the device needs to be replaced or duplicated, the uSD card can be used to clone it.


RDS E3 and RDS E5 are provided with modern GUI (Graphical User Interface) that uses clear elements and useful information. The wide range of the available banners allows the user to monitor any function. The selected banners are always visible in any menu.In the RDS section, a specific area is available for on-air RDS group analysis (static and dynamic) to evaluate services balancing.Thanks to the FM Tuner (as an option), the FM signal can be received and decoded. With this feature it is possible to check MPX, RDS and Pilot deviations, BLER (Block Error Ratio) and RDS Decoder (PI, PS, RT, PTY, RT+,TP, TA, M/S, CT,AF,TMC, EON).
