Moxa’s W406 RISC-based wireless embedded computer
provides a sophisticated wireless M2M solution for
distributed Modbus meters and RTU devices. The W406
networks Modbus meters and RTU devices with Modbus
RTU/ASCII protocolsl via GSM/GPRS/EDGE or Ethernet
to Modbus TCP, and can connect an unlimited number
of serial slaves to an IP network. With built-in
protocol conversion functionality, the W406 can
serve as both serial master and slave, and the built-in
IPSec and encrypted wireless machine to machine
communications ensure the security of your communications.
The DA-681 x86-based rackmount embedded computer can be used as a smart gateway with sophisticated M2M solutions to help construct a tunnel server (IPSec) and bi-directional IP communications. The DA-681 can serve as a secure networking host over IPSec to back-end host computers and Modbus TCP Master/Slave devices. One of the key benefits of this architecture is that it can work with an unlimited number of W406 embedded computers to facilitate and accelerate the remote monitoring and management of Modbus meter and RTU devices.
