3 CIR sensors in different angles
Only one of the front USB ports can support CIR. When CIR is
enabled, the other ports will remain USB ports.
The Multi-Angle CIR Receiver is used for the front USB only.
Please do not use the rear USB bracket to connect it on the rear
panel. The Multi-Angle CIR Receiver can receive multi-directional
infrared signals (top, down and front), which is compatible with
most of the chassis on the market.
The Multi-Angle CIR Receiver does not support Hot-Plug. Please
install it before you boot the system.
