Overview
The W345 is an embedded Linux computer that features 4 software selectable RS-232/422/485 ports, 1 Ethernet port, and quad-band GSM/GPRS 900/1800/850/1900 MHz for cellular communication. In addition,the W345 has 2 USB 2.0 hosts, and 1 relay output, and the W345 come with an SD socket for external storage expansion. The W345’s LinuxOS runs on the MOXA ART 32-bit ARM9 processor, which 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.
