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.
