core module with 2 serial ports, dual LANs, SD, μClinux(Operating Temperature: -10 to 60°C)
The EM-1220 embedded module features 2 RS-232/422/485 serial ports, dual Ethernet ports, and an SD socket for external storage expansion. The module has a compact design that can be easily integrated with industrial applications, such as gas stations, vending machines, and ticketing machines, and offers a powerful serial communication capability for better system integration. Programmers will find that the pre-installed, ready-to-run μClinux platform and the full-function development kit make it easy to develop software and build a reliable communication base for industrial automation applications. In addition, the “wide temperature” EM-1220-T model is also available to provide a reliable solution for any harsh environment.
