ET series includes 9.7”, 13.3” and 31.2” e-paper digital signage devices, which feature Power over Ethernet (PoE) as well as RFID/NFC and touch buttons for local interaction.
E-paper displays blend into the background with its natural tone and sleek design, therefore, reducing visual noise while providing users with crucial information. The displays are energy efficient, sunlight readable, have a wide view angle, are easy on the eyes and have a paper-like quality. The low power consumption, wired data connections and batteryless installation of ET series ensure that the EMC and heat dissipation as well as regular maintenance is kept at minimum. Furthermore, the intrinsic properties of e-paper guarantee that the displayed image is preserved even after the loss of power.
A central management server (CMS) is available for large installations, that makes it convenient to manage and change the content as well as the behavior of hundreds of e-paper devices via a single Web interface. A standalone version of the CMS is available for smaller installations, which makes it possible to manage the devices separately via a Web interface without installing any additional software.
ET series is designed for permanently installed indoor signage solutions, e.g. multilingual exhibitions at museums, patient information in hospitals and information boards or schedules in offices and universities. However, system integrators are not limited to existing solutions, as the flexibility of the platform enables the creation of novel applications.
Among others, the first generation of the devices are in use at the Estonian National Museum with 850+ displays installed and the second generation of the device are in use at the University of Tartu. Read more about these use cases:

The e-paper display devices contain an internal flash storage for offline operation. The pre-rendered images are uploaded from the server or the standalone Web interface to the device’s embedded HTTP server over REST API. The devices send operational data to the server as SNMP TRAP messages. Devices contain a local configurable sequence engine, that handles local events. Following rules in the configuration file, the sequencer coordinates the image update in response to card scans, touch button presses and timeouts.
Central Management Server
The ET series display devices connect to a back-end centralized management server via Ethernet network (DHCP, HTTP, SNMP). The server polls the device status periodically. RFID card scans and touch button presses are sent to the server directly via SNMP for logging. The CMS has a Web interface, which enables site administrators to manage the behavior of the devices and the media files.
Additionally, the CMS has an API for custom integrations with third party applications.
