Administration Guide for Cisco TelePresence Software Release 1.9

Managing Displays

A display is set up successfully when the color on the display has been adjusted for the lighting in the meeting room.

Note Each display must be adjusted individually.

Use the information in the following sections to adjust the display for your system:

• Selecting the Light Level
• Adjusting Your Display
• Troubleshooting Displays
• Related Information

Selecting the Light Level

When adjusting the images on the CTS display screens, you must take the color temperature of the ambient light in the room into consideration.

Sources of light in most rooms are produced by fluorescent fixtures or incandescent light bulbs that use tungsten filaments. Each of these light sources, and the amount of light in terms of lumens or watts, produces a different color temperature. This color temperature is sometimes expressed using terms such cool , warm , or daylight , but can be expressed more precisely in kelvins (K) as a numeric value.

The following temperatures can be selected for adjusting the image on the Cisco TelePresence display screens:

• 3500 K
• 4000/4100 K (recommended)
• 5000 K
• 6500 K
• 7500 K

Tip In many cases, the color temperature is printed on the light bulb. If you are unable to ascertain the type and color temperature of light bulbs in the meeting room, experiment with color temperature settings until the color and images on the display screen look lifelike.

Tip It is OK to try a few different color temperatures to see what looks best in the room. Remember, the Color Temperature setting only effects how the local participants see the display, it does not effect the way the room looks to remote participants.

Adjusting Your Display

To adjust a display:

Step 1 Log in to the Cisco TelePresence System Administration interface.

Step 2 Choose Troubleshooting > Hardware Setup.

Step 3 Click the Displays radio button. A test image appears on the screen.

Step 4 Click Start in the Testing box to start the adjustment process. The Current Color Temperature test screen appears, as shown in Figure 1-2.

Note Each display in the meeting room should be showing a set of horizontal grey bars and that display's relative position. The current color temperature setting is displayed.

Troubleshooting Microphones

Use the information in Table 1-4 to troubleshoot microphones.

Table 1-4 Troubleshooting Microphones

Problem	Possible Cause	Possible Solution
Sound is muffled.	Something near or on the microphone is distorting the sound.	Move objects away from the microphone.
No sound registers.	Microphone cable is not connected or is only partially connected.	Check that the system is plugged in and power is on. Check that the microphone plug is firmly seated in the correct connector on the primary codec. Check that the mute light on each microphone is lit. An unlit light indicates that the microphone is not plugged in. Lightly tap the microphone to see if sound registers. Contact Cisco technical support if you are certain that the cabling is correct and power is applied to the system, but no sound registers on the microphone.
Microphone icon with red pipe displays.	Microphone is not connected. One of the microphones is unplugged.	Check that the microphone is properly plugged in.
Microphone icon with question mark displays.	One of the microphones is unplugged.	Check that the microphone is properly plugged in.
Sound registers at the wrong microphone.	Microphone cable is not connected to its corresponding codec.	Check that the cable from the microphone is plugged into the correct receptor on the codec. Plug all microphones into the primary codec.
Microphone switches to a segment that has no one talking.	Phantom switching.	Run the microphone calibration procedure in the “Testing Microphones on the CTS 3000” section or “Testing Microphones on the CTS 3200” section.
Choppy audio during double-talk (when both sides are talking simultaneously).	Audio Echo Canceller (AEC) very briefly mistakes one of the speech patterns for noise and cancels it, resulting in choppy audio. The audio from the remote side is slightly attenuated before it is played out the of the speaker. The echo cancellation feature removes some of the sound from the talkers during the double talk.	Check whether there has been a change in the echo path (someone has moved the speaker or microphone, or maybe a laptop directly in front of a mic). Otherwise, this is expected behavior. The existing filter parameters should be enough to cancel out the sound from the speaker. However, during double-talk, echo cancellation will always remove some sound from the talker.

Troubleshooting Presentation Devices

Use the information in the following sections to troubleshoot presentation devices:

• Multiple Input Devices
• Presentation Devices

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 projector displays the input from the last presentation device sending 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 1-5 to troubleshoot presentation devices.

Table 1-5 Troubleshooting Presentation Devices

Problem	Possible Cause	Possible Solution
Test pattern is not displayed.	Projector power switch is off.	Check projector power switch. Switch the projector on/off rocker switch to the ON position.
	Power cable is not connected.	Check to see if the LED on the top of the projector is illuminated. It can be either green or yellow. If the LED light is not illuminated, make sure that the power cable is plugged in.
	Video cable is not connected to the projector or to the CTS primary unit.	Check that the video cable is plugged into the projector and into the correct connector on the CTS primary unit. Contact Cisco technical support if you are certain that the cabling is correct and power is applied to the system but no image is displayed.
	Projector is set up to receive PC input instead of input from its video cable connector.	Use the projector remote control to configure the projector for HD Video input. If your system includes an Auxiliary Control Unit, click Set Projector Defaults.
	Object is blocking the path of the projector.	Remove any objects blocking the projector lens.
	HD Video connector is not securely seated in the projector.	Seat the HD Video connector securely.
	HD Video connector is not securely seated in the CTS primary codec.	Seat the HD Video connector securely.
	HD Video connector is not inserted in the correct port on the CTS primary codec.	The HD Video cable connector should be connected to auxiliary video out. Check the cabling diagrams in the Routing Power and Signal Cables section in the following documentation: Cisco TelePresence System 3000 Assembly, Use & Care, and Field Replacement Unit Guide Cisco TelePresence System 3200 Assembly, Use & Care, and Field Replacement Unit Guide
Projector image is dim.	Lamp iris needs to be set to open.	See the Setting Up the Camera section in the following documentation: Cisco TelePresence System 3000 Assembly, Use & Care, and Field Replacement Unit Guide Cisco TelePresence System 3200 Assembly, Use & Care, and Field Replacement Unit Guide
System Status window shows unexpected Document Camera status.	Document camera settings may need to be adjusted in 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 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.

Or

b. Click Select All to select all ports (and all light units) or Select None .

c. Click the Refresh On/Off Status button to update the on/off status of each port.

d. Click the Turn Selected Lights On/Off to test the selected light unit(s).

e. Click the Reset Auxiliary Control Unit to power cycle the Auxiliary Control Unit.

Step 5 Click Stop to end the test.

Digital Media Player

The Digital Media Player (DMP) feature lets you select a secondary audio input source when you are not in a TelePresence call.

For more information about the DMP, see the Cisco Digital Media Players home page on Cisco.com.

To test the DMP:

Step 1 Log in to the Cisco TelePresence System Administration interface.

Step 2 Choose Troubleshooting > Hardware Setup.

Step 3 Click the DMP tab.

Step 4 Click Start in the Testing box to begin testing the secondary audio input.

• If you have a PC attached, the Secondary Audio Input Source PC button is highlighted. When Secondary Audio Input Source is set to PC, the audio input is active while the presentation source is active, both in and out of a call.
• If you have a DMP attached, the Secondary Audio Input Source DMP button is highlighted. When set to DMP, audio input is only active outside of a call if DMP is active (during business hours defined by Unified CM).

Note The DMP settings should match how the secondary auxiliary audio input is physically connected to the codec.

Step 5 Click Stop to end the test.

Troubleshooting Other Devices

Use the information in Table 1-6 to troubleshoot problems in Other Devices.

Table 1-6 Troubleshooting Other Devices

Problem	Possible Cause	Possible Solution
Digital Media Player DMP audio is playing during a call.	Secondary Audio Input Source setting may be wrong.	Check to see that the Secondary Audio Input Source setting matches the physical cabling. When set to PC, the audio input is active while the presentation source is active, both in and out of a call.
Presentation Devices Local presentation audio is not playing during a call.	The Secondary Audio Input Source setting may be wrong.	Check to see that the Secondary Audio Input Source setting matches the physical cabling. When set to DMP, audio input is only active outside of a call if DMP is active (during Cisco Unified Communications Manager-defined business hours).
Presentation fails to display in some resume scenarios.	This is expected behavior.	In early CTS software releases, a CTS with its presentation device plugged in would always ask to present when it did a resume. Presentation device functionality is changed. When a CTS goes on hold, the presentation device takes note whether or not it was the active presenter: If the presentation device was the active presenter when it went on hold, it will ask to present again when taken off hold and the presentation will be shown when the meeting resumes. If it was not the active presenter, it will not ask to present and the presentation will not be shown when the meeting resumes.
Administration login can be slow when presenting during point-to-point secure calls.	This is expected behavior.	Administration CLI login can take as much as 60 seconds during point-to-point secure calls when a hold/resume is performed while presenting.
Tip Other devices automatically shut off when there is no longer a video signal to that 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 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.
