JetBox 9300/9300-w - Industrial Networking Solutions – Industrial Ethernet Switches and Routers

JetBox 9300/9300-w


In a networking communication environment, router, switch and computer are indispensable devices to a typical networking architecture. The demand for data exchange between simple sensors, various I/O controllers, serial devices, PoE switches, routers, wireless LAN and desktop systems increases. These networking equipment would be faced the difficulty and complexity of software/hardware compatibility. JetBox 9300 is a global pioneer to invent 5 in 1 Industrial Networking Computer which consolidates Industrial Computer, Router and Managed Switch with option of PoE switch. In addition, it equipped with the interfaces of serial server and digital I/O is making the network simple. JetBox 9300 can easily be the central computer in Automatic Control Systems; it collects the system signals and controls the on-site devices. It can monitor the whole control system through its router and Ethernet switch functionalities by forming the control system to a simple network with Ethernet. In addition, it is equipped with serial server and I/O controller which can monitor the serial devices in the control system, along with I/O signals collection, it is the total solution of networking computer.
