Features and Benefits
OverviewThe W321 is an embedded Linux computer that features 2 software selectable RS-232/422/485 ports, and support the IEEE 802.1a/b/g standards for WLAN connections. In addition, the computer has 1 Ethernet port, and comes with an SD socket for storage expansion. The W321'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. More info >> |
