Troubleshooting Presentation Devices
Problem
System Status window shows
unexpected Document Camera
status.
Note
The Cisco TelePresence System can display information from multiple input devices during a meeting; if multiple
input devices are sending information, the projector displays the input from the last presentation device sending
information. If you do not see an image being projected on the screen, try the following:
For VGA devices, unplug the device from the VGA cable, wait 5 seconds, and then plug the device back in.
For document cameras, turn the camera off, wait 5 seconds, and then restart the device.
Tip
Presentation devices automatically shut off when there is no longer a video signal to that presentation device. An
on-screen timer counts down the remaining time to shut-down. The amount of time that it takes a device to shut down
depends on your Cisco Unified CM configuration. Most CTS devices that support
after the video signal is removed. Devices on the CTS 3000 and CTS 3200 series that have black boxes associated
with the auxiliary control take 5 minutes to shut down. See the Product Specific Configuration Layout section of the
Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System
information about controlling presentation devices and associated displays.
Important Notes About Presentation Displays
Supported Video Protocols
If the video works for a few minutes and then stops working, your presentation device might use an
unsupported video protocol. To see the list of displays that the CTS 3000 and CTS 3200 supports, see
the release notes for your CTS software version on Cisco.com.
Local Presentations and PiP
Expected behavior: The local presentation from the document camera is not showing as PiP in the center
display screen after the auxiliary monitor is switched off. After a call is made the display is shared and
shown on the remote side but not locally. The sysop logs show the presentation rate as 30 fps instead of
5 fps. The reason for this is that the presentation monitor is connected to an audio extension board (AEB)
box, so when the monitor is switched off, the AEB box does not detect that it is now 5 fps instead of
30 fps. When the presentation codec is directly connected to the auxiliary monitor, the issue does not
happen. Cisco recommends that you connect the presentation codec directly to the auxiliary monitor.
