Step3. Install Multi-Angle CIR Receiver to
the front USB port. If Multi-Angle
CIR Receiver cannot successfully
receive the infrared signals from
MCE Remote Controller, please try
to install it to the other front USB
port.
3 CIR sensors in different angles
1. Only one of the front USB port can support CIR function. When the
CIR function is enabled, the other port will remain USB function.
2. Multi-Angle CIR Receiver is used for front USB only. Please do not
use the rear USB bracket to connect it on the rear panel. Multi-Angle
CIR Receiver
can receive the multi-direction infrared signals (top,
down and front), which is compatible with most of the chassis on the
market.
3. The Multi-Angle CIR Receiver does not support Hot-Plug function.
Please install it before you boot the system.
