New 6-digit display allows data display from RS232 and RS485 serial interfaces

The new SerialDis display , available from Celsum Technologies, is a packaged in a rugged ABS housing sealed to IP65, and is ideal for when a data display driven by an RS232 or RS485 interface in required. SerialDis has six bright, red, 7-segment LEDs, nominally 20mm high, that can be programmed to display data. from a PC or directly from a suitably configured device. Celsum offers several such devices, such as the radio telelmetry T24-SO serial output model, and some models of both the DSC Digital Strain Card and DCell Digital Strain Puck digital-output conditioning amplifers for strain gauge devices. Single or multi-drop devices are supported, since SerialDis has addressing support.

SerialDis can operate at baud rates from 9,600 to 115,200, and uses 8 data bits, 1 stop bit and no parity. It needs a supply voltage of between 8 and 18V DC, and has a 200mA nominal current consumption. The minimum value that can be displayed is 0.00001, and the maximum is 199999. Power for connected serial devices is available, between 8 and 15V DC.

SerialDis has many applications, from laboratories to the factory floor, for diverse applications such as weight, temperature, force, pressure, humidity, speed, and more.

Rio de Janeiro announcement from The City of Rio de Janeiro and X, The Moonshot Factory, Taara announced a trailblasing new partnership to deploy the world’s first mesh network of high-speed wireless optical links to deliver fast, abundant and secure connectivity to schools, hospitals and city offices in Rio. Our goal is to bridge connectivity gaps across the city and provide fast, affordable connectivity to critical services like schools, hospitals, government centres, and in disaster response situations. In the same way traditional fibre uses light to carry data through cables in the ground, Taara uses narrow, invisible beams of light to transmit information at speeds as high as 20 gigabits per second, up to distances of 20 kilometres per link. Taara connects into existing fibre networks and bridges the gap where fibre and other technologies can’t reach. Instead of waiting months or years to dig up the earth and lay new fibre cables, Taara’s links can be established within hours. In Rio de Janeiro, Taara will install 20+ links to deliver service to communities where connectivity is spotty or unreliable. The links will create an invisible mesh network over parts of the city that will serve as a single responsive system – connecting community institutions like schools and hospitals and helping facilitate emergency response. A new approach for urban connectivity in Rio Although Brazil ranks among the world’s five largest internet economies, connectivity remains spotty – more than half of the population uses smartphones to get online, and existing cellular infrastructure varies by community. In Rio, some of the most stubborn, hard-to-connect areas are also the city’s most populated. Built of brick, concrete, and steel rooftops through a labyrinthine tangle of narrow streets and uneven terrain, it’s nearly impossible to connect these communities via traditional broadband fibre. Taara’s links, which can be mounted flexibly on rooftops, towers, and poles, are well suited to these challenging terrains and combine the reliability and speed of fibre infrastructure with the flexibility of wireless technologies. To date, Taara has successfully delivered reliable, abundant internet to people in more than 20 countries. This includes providing access in dense urban communities in India and Africa, delivering fast affordable connectivity to island nations in the Pacific and the Caribbean after natural disasters, and beaming connectivity over rivers, sea straits, and other places where laying fibre is too impractical or costly. Taara is honoured to be supporting Rio’s AI City vision and its mission to transform the region into a global innovation hub. We hope Taara’s first mesh network in Rio can serve as a blueprint for urban connectivity and inspire a more connected, intelligent, and inclusive world.
