1. Connect your HDMI source device to the HDMI IN port.
2. Connect your DVI display or projector to the DVI-I OUT port.
3. Connect your S/PDIF AV receiver to the S/PDIF RCA port.
4. Connect your PC speaker to the Stereo 3.5mm earphone jack.
5. Power up the CV-511.
* S/PDIF format is dependent upon the embedded digital audio part in the input HDMI stream. The S/PDIF receiver
must be able to recognize the input S/PDIF format. This CV-511 only separates the digital audio in HDMI stream,
and bypasses this decoded audio to the output.
* The function of the rotary switch is reserved and please keep the rotary switch at 0.
1. Power up the CV-511. Connect DVI display to the DVI OUT.
2. Turn the rotary switch counterclockwise [] from 0 to 7.
3. The green LED will flash a few times to indicate the EDID is learned.
4. Turn the rotary switch clockwise [] from 7 to 0. DO NOT let the rotary switch arrow pass 6, which will
erase the just learned EDID and reset to default EDID.
1. Analog stereo audio output can merely support 2-channel audio. This version does NOT support
8-channel analog audio applications.
2. S/PDIF audio output supports main 2-channel audio output only.
