Dual display support
t220L supports DVI-I and DVI-D for dual display, up to 1920 x 1200 resolution.
Smart card reader
The smart card reader is offered as an option for higher authentication standard.
Durable and quiet design
t220L's efficiently thermal design not only eliminates the need for traditional fans, but also increases system stability and extends product lifetime. The t220L also improves workplace quality because of its noiseless design.
Simplified management
ADM provides a centralized management tool to replace traditional method of configuring each PC. ADM allows MIS staff to set different privilege levels for individual t220L clients. MIS staff can also install/remove applications in/from t220L from a remote site via internet. Devices such as USB ports in t220L can be enable/disable by MIS staff through the same way.
Compact and robust design
t220L weighs 1.0Kg (approximate) in a compact enclosure keeping desk space usage to a minimum.
Low power consumption
t220L consumes minimal power in its idle state. Compared to normal desktop computers, it saves a considerable amount of an enterprises' energy bill.
Lower total cost of ownership
t220L requires little cost of acquisition. Furthermore, the server-based computing also significantly reduces the IT manpower need for management and maintenance.
