Siretta, a British designer and manufacturer of wireless modems, terminals and antennas, has announced the ZEST range, starting with a dual-band GSM/GPRS terminal that sets a new price-point of under £40. Cellular modems allow engineers to deploy wireless communications in applications including machine-to-machine (M2M) and Internet of Things (IoT) without the need for specialist wireless design skills, long design-in cycles or complex wireless certifications.
ZEST provides cellular data connectivity for applications to be deployed in a wide range of countries including EMEA and Asia, providing a complete, certified wireless connectivity for applications that need to communicate data via the cellular network. For most applications modems provide a better option than using modules or components as they eliminate the design and certification that can add significant cost and delays to product development. At the new price point of less than £40, the GPRS version of ZEST can reduce the total cost of production of for volumes up to 10K units/year.
“By pushing the price point to a new level, we have allowed many more applications to benefit from the reduction in development timescales, elimination of certification risk and improved total cost offered by modems,” said Nick Lidington, chairman of Siretta. “Applications such as automatic meter reading, remote vending machine management, LED signage and POS connectivity that struggled to justify the unit cost will rapidly switch to terminal technology.”
Housed in a compact package measuring just 75 mm x 84 mm x 31 mm, ZEST can be either wall or DIN rail mounted. It accepts a flexible power supply of 6 to 18 V, and the -40°C to +85°C industrial operating temperature range allow the product to be used in applications with harsh environmental requirements.
The interface is an RS232 port, which allows software engineers to use either AT commands or Python script when developing applications. With the development team based in the UK, Siretta offers particular advantages to European customers who will benefit from outstanding local support. The 3G version of the ZEST will follow shortly and will additionally feature a full USB interface in addition to the RS232.
