The W311/321/341 embedded Linux computers feature 1, 2, or 4
software selectable RS-232/422/485 ports, and support the IEEE
802.1a/b/g standards for WLAN connections. In addition, the
computers have 1 Ethernet port, and some models come with USB
2.0 hosts and an SD socket for storage expansion. The W311/321/341
computers’ Linux OS runs on the MOXA ART 32-bit ARM9 processor
that 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.
