MOXA EM-1220-T

The MOXA EM-1220-T 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 station pumps, 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. The EM-1220-T is a "wide temperature" model that operates reliably in temperatures ranging from -40 to 75°C, making the module suitable for even the harshest industrial environments.
Industrial-grade Module for Industrial Applications The EM-1220-T comes with 2 software-selectable RS-232/422/485 serial ports for attaching different types of industrial devices. In addition, the MOXA ART ARM9 32-bit 192 MHz processor promises a powerful performance for system operation. The two auto-sensing 10/100 Mbps Ethernet ports default to the higher 100M speed when available, and ensure network connectivity redundancy. In addition, the 8 GPIO pins provide ample design flexibility, giving you the freedom to develop the features your customers need. The SD socket also provides an efficient way for storage expansion. These features are better suited for today’s equipment, and R&D engineers will spend less effort developing related software.
Short Time to Market The ready-to-run µClinux operating system allows you to minimize your system development effort, and get your product to market in no time.
Easy-to-Use Development Kit The EM-1220-T Development Kit can be ordered separately for evaluating the EM-1220 embedded module. The kit includes an EM-1220-T embedded module, an EM-1220-DK carrier board, and the items needed for setting up a basic layout. The kit makes it easy for users to evaluate the functionality of the EM-1220. You can develop and integrate specific systems on the module in advance to make the EM-1220 embedded module completely compatible with industrial systems and applications.
