Measuring 75x84x31mm, the ZEST modems can be wall or DIN rail mounted. The modems accept a power supply of 6-18V and operate across a temperature range of -40 to +85˚C, making them suitable for use in harsh environments. The interface is an RS232 port, which allows software engineers to use either AT commands or Python script when developing applications.
By removing the need for design and certification, cellular modems provide engineers with a cost-effective alternative to using modules or components. The ZEST range of 2G cellular modems is available now and priced at under £40.
“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, Siretta. “Applications such as automatic meter reading, remote vending machine management, LED signage and POS connectivity, which struggled to justify the unit cost, will rapidly switch to terminal technology.”
