Overview

The Moxa W341 is an embedded Linux computer that features 4 software selectable RS-232/422/485 ports, and support the IEEE 802.1a/b/g standards for WLAN connections. In addition, the computers have1 Ethernet port, and some models come with USB 2.0 hosts and an SD socket for storage expansion. The W341's Linux OS runs on the MOXA ART 32-bit ARM9 processor, and provides a powerful and reliable platform for harsh, industrial environments. You will find these computers ideal for a variety of machine-to-machine applications,including data acquisition, protocol conversion, and remote device control and monitoring.
