For more information about setting up and testing presentation devices, see the following
documentation:
System Status window shows
unexpected Document Camera
status.
Document camera settings may
need to be adjusted in
Cisco Unified CM.
Cisco recommends setting the Digital Visual Interface
(DVI) resolution to XGA/60 at 1024 x 768/60 Hz. See
the Optional Hardware section of the
Cisco Unified
Communications Manager Configuration Guide for the
Cisco TelePresence System
for more information.
There is no image and a Bulb
icon appears on the CTS main
display.
The projector bulb has burned
out.
Replace the projector bulb.
CTS 3000 and CTS 3200 system
projector alarms:
•
Operation Status: Failed to
connect to presentation
device
•
XML/RPC failure
•
Operation Status: ERROR
The projector serial port is not
functioning properly
On CTS 3000 and CTS 3200
systems that use a Z60 projector
to display external presentations,
the system pushes default values
to the projector every night.
During these updates, the system
can fail to connect to the
projector. This failure creates
syslog messages and can cause
spurious SNMP alarms.
Power cycle the projector by turning the power switch
on the back of the projector to the Off position, then
turn back to the On position. If this problem recurs,
perform another power cycle.
Note
Projector functionality is not affected by the
alarms.
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
PiP
shut down in 10 to 15 seconds
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
for more
information about controlling presentation devices and associated displays.
