Atrust t20 is a Windows® 10 IoT Enterprise OS based thin client. The Aspeed AST2500 BMC ( Baseboard Management Controller ) chip is also built in to help effective remote management on each t20 device. With the support of BMC, it allows a system administrator to perform different monitoring and management tasks remotely without having to be physically located next to the system – such as firmware updating, BIOS updating and system hardware monitoring. The BMC will also notify the administrator via email if there is hardware abnormal. The BMC is an extremely efficient time saving tool – the administrator no longer needs to do the physically on-site checking.

Durable design
The t20's efficiently thermal design not only eliminates the need for traditional fans, but also increases system stability and extends product lifetime.
Low total cost of ownership
Additional computing access is as simple as adding more I/O devices. The total cost of ownership is then drastically reduced.
Simple click and play
t20 connects to the host server with a Remote Desktop connection. Just click the shortcut for a Remote Desktop session, you can immediately start a session and enjoy the computing resources.
Rich remote user experience
With Citrix® ICA / HDX™, Microsoft® RDP with RemoteFX™ and VMware® Horizon View™, t10A can provide a rich, efficient, and “local” computing experience for remote users.
Easy management and maintenance
Since all computing tasks are mainly performed on a server, all hardware and software issues are significantly reduced on the client side. All user management, software installations, system management, and upgrades are done on a single server.
