Cisco Cisco Digital Media Player 4300G 설치 가이드

Make sure that your DMP has attributed an authentically HDMI-standard resolution value — such as 
“HDMI_1080p60” — to your presentation system (CSCsk29797). The HDMI standard does not 
support audio playback through any system whose settings ignore or contradoct HDMI standards. 
Thus, you cannot use HDMI to play audio through a presentation system whose resolution setting 
is, for example, “VESA_1360x768x60.”

Compensate for known factors. 

If this happens to you, unplug the serial cable (or USB cable) that connects this touchscreen to 
your DMP. Then, plug that cable back in again.

Your DMP is equipped with an infrared (IR) sensor that receives, recognizes, and 
reacts to the signals from a DMP remote control. 

However, the way that you mount your DMP can limit how well it responds to these 
signals. For example, the mounting method might block the IR sensor. This in turn 
might cause you to attach an IR extension cable to your DMP, as a workaround. 

But even when you mount the receptor from this extension where it is not 
obstructed — and even though this method improves the reception of IR signals that 
are blocked otherwise — IR extension cables are not perfect. The physics that 
underlie their design ensure that these cables always have some signal loss, 

Furthermore, greater cable length contributes greater signal loss. Thus, the field 
(angle) of transmission becomes narrower for a remote control and the range 
(distance) becomes shorter in direct proportion to the length of the IR extension cable.

Prevent sunlight from shining directly on your DMP’s IR sensor. And take further 
steps as needed to stop halogen bulbs from shining at the sensor.
