Atrust m321 is a zero client designed as an endpoint of a shared resource system, such as a MultiPoint Server system. The solution enables a host server to power multiple and independent stations. Each station only consists of one station hub ( zero client ) with a keyboard, mouse, and monitor connected, allowing multiple users to share the computing power of one single server. Simply through an Ethernet connection, the server provides each station user with a familiar and independent Windows® experience.

Low total cost of ownership ( TCO )
Additional computing access is as simple as adding more I/O devices. The total cost of ownership is then drastically reduced.
Slim and quiet design
m321 is feather light weighing only 160g ( approximate ). The slim design allows it to be mounted to the back of a monitor with a VESA mount. Together with its fanless design, m321 helps create a simple and noiseless workplace environment.
LAN-based connection
m321 connects to the host server with an Ethernet cable. This connection type exceeds the length limit of a USB connection and provides more flexibility in the layout of a MultiPoint Server system.
Simple setup
Just attach a keyboard, mouse, and monitor to your m321, connect it to the host server, and then perform the initial setup. A station is ready for use right away.
Easy management and maintenance
Since all computing tasks are performed on a server, all hardware and software issues are gone on the client side. All user management, software installations, system management, and upgrades are done on a single server.
