Multiple Input Devices
The Cisco TelePresence System can display information from multiple input devices during a meeting.
If multiple input devices are sending information, the alternate display shows the input from the last
presentation device that sent information. If an input device image is not being seen on the projector
screen, try the following:
•
VGA devices—Unplug the device from the VGA cable, wait 5 seconds, and then plug the device
back in.
• Document cameras—Turn the camera off, wait 5 seconds, and restart the device.
Presentation Devices
Use the information in Table 4-6 to troubleshoot presentation devices.
