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.

Testing Cameras

The cameras are set up successfully when images are centered and in focus on the display screens and the white balance has been configured. The hardware setup software provides a camera Auto Adjust feature and a way to use targets to fine-tune the camera’s focus.

Note You must use the camera Auto Adjust feature before you can auto focus the camera. See the “Tuning the Camera” section.

Use the information in the following sections to test and troubleshoot the camera for your system:

• Testing the CTS 1000 Camera
• Understanding Camera Setup Choices for Room Lighting
• Troubleshooting Cameras
• Related Information

Note The camera hood comes off. It should be removed and left off until these procedures are complete.

Testing the CTS 1000 Camera

The following sections describe how to set up the CTS 1000 camera for testing:

• Removing the Camera Hood
• Assembling and Setting Up the Camera Targets
• Aligning the Camera
• Setting the Field Depth
• Calibrating the CTS 1000 Camera
• Saving Your Settings
• Attaching the Camera Hood

Removing the Camera Hood

Removing the camera hood provides access to the zoom and focus rings for the camera. To remove the camera hood:

Step 1 Find the two screw holes in the bottom of the camera hood and unscrew the two M4 x 10 mm screws.

Step 2 Remove the hood from the camera.

Assembling and Setting Up the Camera Targets

The Cisco TelePresence System uses targets to set focus and camera alignment and to help with color balance. Two targets are used. This section describes how to assemble and set up the camera targets.

To assemble and set up the camera targets:

Step 1 Carefully open the box containing the two targets and the target frame components. The frame elements are in the bottom of the box.

Note Take care not to damage the box. When you are finished with the camera adjustment procedure, you can disassemble and store the target in the box for future use.

Step 2 Lay the two metal frames on the floor.

Step 3 Attach the two frame pieces with the screws.

Step 4 Locate the horizontal center point in the Cisco TelePresence System 1000 frame and mark the corresponding point on the table.

Step 5 Attach the camera target frame to the table by tightening the clamps to the table edge, as shown in Figure 1-3. The target should be attached on the side of the table where the participants sit and the target should be facing the camera.

Tip The edge of the table should be 4 to 8 feet (1.2 to 2.4 meters) from the camera.

Figure 1-3 Target Attached to the Tabletop Edge

Step 6 Unfold the large cardboard target.

Step 7 Insert the cardboard into the channels on the frame with the printed side facing the display.

Step 8 Push the target into the frame until the two registration marks on the upper right and left edges match the ends of the top metal frame. See Figure 1-3.

Tip To identify the corresponding point on the table, you can measure the distance from a side wall to the center point in the frame then from the same wall apply the measurement to the table.

Step 9 On the edge of the table across from the wall, align the vertical line in the target with the center point in the frame.

Step 10 Fit the clamp ends of the target fixture over the table top and tighten the screws to secure.

Aligning the Camera

To set the camera alignment using the Cisco TelePresence System Administration interface:

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

Step 2 Choose Troubleshooting > Hardware Setup .

Step 3 Click the Cameras radio button.

Step 4 Click Start . The display enters loopback mode. In loopback mode, the display shows images from the camera.

Step 5 Click Show Camera Target .

Note Make sure that the camera target is still secured to the table.

Step 6 Loosen the thumbscrew on the camera and twist the zoom ring on the lens until the curved lines on the left and right are just touching the left and right borders of the screen. Tighten the thumbscrew when the adjustment is complete.

Step 7 If required, align the camera so that the target is centered in the picture by using the screw-and-spring mechanisms on the camera mounting plate that is shown in Figure 1-4.

You can adjust the pan (the panoramic sweep on the x-axis) and pitch (the fore-to-aft tilt on the y-axis) angles, and pivot. These angles are adjusted using the three sets of screws shown in Figure 1-4. The angles the screws adjust are as follows:

• Middle two screws—Allows you to set the yaw angle of the camera. See “Setting the Camera Yaw” section for more information.
• Top screw —Sets the pan angle. See “Adjusting the Pan of the Camera” section for more information.
• Bottom screw—Sets the pitch angle. See “Adjusting the Tilt of the Camera” section for more information.

Note These adjustment capabilities are moderate and might not correct for a display frame that is not level.

• Camera Auto Brightness
• Camera Auto Color Balance

Step 2 Click Setup , then click Auto Adjust to automatically adjust lighting and color balance.

Note Make sure that the large target is still in place and that nothing is between the large target and the camera.

The camera calibrates and saves the settings. This process takes approximately 10 seconds. If the test fails, you may need to add more light to the room.

Step 3 If you require further adjustments to the room brightness, do the following:

a. Repeat Step 1.

b. Select a choice from the Luminance drop-down menu until the brightness and contrast are at acceptable levels.

Step 4 Adjust for variable lighting. If the room uses outside lighting, or has any other conditions that could cause variable room lighting, click the Enable radio button for the following:

• Camera Auto Brightness
• Camera Auto Color Balance

Note Auto Color Balance can produce undesirable results if the colors of the walls in your room are not white or gray.

Step 5 To make additional adjustments to the camera brightness and contrast levels, select a choice from the Luminance drop-down menu.

Note Make sure that the large target is still in place and that nothing is between the large target and the camera.

The camera calibrates and saves the settings. This process takes approximately 10 seconds. If the test fails, you may need to add more light to the room.

Step 6 Adjust for flickering. If you encounter flickering on the screen, click Enable to turn on 50Hz Flicker Reduction.

Note If you are in country that uses a 50 Hertz (Hz) power frequency (a country other than the USA, Canada or Mexico) and there is a noticeable flicker on the screen, click the Enable radio button in this field. If you enable the flicker reduction feature, the flicker is reduced or eliminated, but the image quality is reduced. To eliminate the flicker at its source, you can use an electronic ballast instead of a magnet ballast for the fluorescent lights at your installation. After you change the ballast for the fluorescent lights, you can click the Disable radio button in the 50 Hz Flicker Reduction field.

Step 7 Adjust the Focus Distance using the following as a guide:

• If the user is 1.2 meters to 1.5 meters (4 to 5 feet) away from the display, click 4 feet .
• If the user is farther than 1.5 meters (5 feet) away, click 6 feet .

Step 8 Make sure that the large target is still in place and that nothing is between the large target and the camera.

Step 9 The camera calibrates and saves the settings. This process takes approximately 10 seconds.

Note If the test fails, you may need to add more light to the room.

• If the room uses outside lighting, or has any other conditions that could cause variable room lighting, click the Enable radio button for the Camera Auto Brightness and Camera Auto Color Balance choices.

Note Auto Color Balance can produce undesirable results if the colors of the walls in your room are not white or gray.

Step 10 If you encounter flickering on the screen, change the 50Hz Flicker Reduction choice to Enable .

Step 11 If the user is 1.2 meters to 1.5 meters (four to five feet) away from the display, click the 4 feet radio button for the Focus Distance radio choice. If the user is farther than 1.5 meters (five feet) away, click the 6 feet choice.

Step 12 Click Apply .

Setting the Camera Yaw

The yaw indicates how level the picture is as it is projected on the display. Objects on the display appear to slant to viewers. A yaw error occurs when the camera is positioned at an angle. Yaw can be adjusted by pivoting the camera lens. This section describes how to adjust the camera so that it is level.

Tip Yaw errors also occur when the frame is not level. Be sure that the CTS 1000 frame is level.

To adjust the yaw angle:

Step 1 Loosen the two middle screws just above the camera lens with an Allen wrench (a 3.0 mm Allen wrench shipped in the original CTS 1000 kit).

Step 2 Do one of the following:

• If the image on the display is slanting to your left, gently pivot the camera lens clockwise.
• If the image on the display is slanting to your right, gently pivot the camera lens counter clockwise.

Step 3 When the yaw angle is adjusted satisfactorily, slowly and carefully tighten the middle screws so that the yaw angle is preserved.

Adjusting the Pan of the Camera

The pan indicates the left-to-right movement along the x-axis. Pan is adjusted using the screw at the top of the camera plate.

To adjust the pan angle:

Step 1 Using a 2.5 mm Allen wrench, do one of the following:

• If the image on the display is too far to your left, insert the Allen wrench into the head of the top screw and turn clockwise.
• If the image on the display is too far to your right, insert the Allen wrench into the head of the top screw and turn counter clockwise.

Adjusting the Tilt of the Camera

The tilt (or pitch) indicates the fore-to-aft angle along the y-axis and appears as an up and down movement to viewers. Tilt is adjusted using the bottom screw on the camera plate.

To adjust the tilt:

Step 1 Using a 2.5 mm Allen wrench, do one of the following:

a. If the image is low, insert the Allen wrench into the head of the screw below the camera and turn it counter clockwise to raise the image.

b. If the image is high, insert the Allen wrench into the head of the screw below the camera and turn it clockwise to lower the image.

Setting the Field Depth

This section describes how to set the field depth. This is the area in which a conference participant can move forward and backward and remain in focus. The process for setting the field depth is partially automated and requires the use of targets. The process is also light sensitive and should be performed immediately following the lighting adjustment procedure described in the “Tuning the Camera” section.

Note To ensure accuracy and success for this process, make sure that light in the camera view is not blocked or disturbed in any way.

Setting Up the Targets

To set up the targets:

Step 1 Set up the following items:

• Large camera target
• Small camera target
• Sixty-inch (1.52 m) long measuring instrument
• Prop to support the large target

Step 2 Place the small camera target on the tabletop four inches (10 centimeters) behind the microphone.

Step 3 Set up the large camera target as follows:

a. Remove it from the tabletop.

b. Orient it so that the target side faces the camera.

c. Stand it on end on the floor approximately 60 inches (150 centimeters) behind the small target.

Note Prop the target against a chair or the wall so that it stands upright.

Step 4 Loosen the set screw on the zoom ring.

Note Some camera models require a 3.0 mm Allen wrench to unlock the zoom ring. A 3.0 mm Allen wrench shipping in the original CTS 1000 setup kit.

Calibrating the CTS 1000 Camera

To calibrate the CTS 1000:

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

Step 2 Choose Troubleshooting > Hardware Setup

Step 3 Click the Cameras radio button.

Step 4 Click Setup .

Step 5 Click Show Focus Target .

Step 6 Calibrate the camera by completing the following steps:

a. Slowly zoom out until the green and red lines move to the edge of the left side of the screen.

b. Slowly zoom in until the green and red lines move to and touch the right edge and move back.

Step 7 Slowly turn the zoom ring back to center until the ends of the red and green lines come as close to aligning as you can get them.

Note The closest alignment will most likely occur about ¾ of the length across the screen.

The lines probably will not align perfectly. Get them as close to even as you can.

Step 8 Tighten the set screw on the zoom ring.

Note Be careful when tightening the set screw. The zoom is very sensitive, and tightening the set screw can change the setting. Reset the zoom if the setting changes.

Tip Step away from the camera to get out of the light. The lines become a little more stable.

Step 9 Click Done.

Step 10 Your image should be in focus when you do the following:

a. Sit in a chair at the table in the camera view.

b. Lean forward onto the table.

c. Lean backward away from the table.

Saving Your Settings

When you have configured all your settings:

Step 1 Click Apply to register new or modified settings.

Step 2 Click Reset to restore the original settings.

For more information about testing and troubleshooting the CTS 1000, see the Setting Up the Camera section in the Cisco TelePresence 1000 Assembly, Use & Care, and Field-Replacement Unit Guide .

Attaching the Camera Hood

To attach the camera hood:

Step 1 Carefully fit the hood lightly over the camera without bumping the camera.

Step 2 Align the two screw holes align in the bottom of the hood with threaded holes in the camera support bracket and secure with two M4 x 10 mm screws.

Understanding Camera Setup Choices for Room Lighting

If your room has windows that contribute a significant amount of natural light, you can set your CTS to automatically compensate for variable lighting conditions. This compensation is an average adjustment and will not be as accurate as the color settings you select for a room that uses fixed, artificial room lighting.

Table 1-2 contains recommendations for desirable display and camera settings when you set up the display and camera. See the “Testing the CTS 1000 Camera” section for more information.

Troubleshooting Cameras

Troubleshooting the CTS 1000 Microphone

Use the information in Table 1-5 to troubleshoot microphones.

Table 1-5 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. Confirm the laptop is not open and in-between the user and 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.
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.

• 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 1-7 to troubleshoot Other Devices.

Table 1-7 Troubleshooting Other Devices

Problem	Possible Cause	Possible Solution
Digital Media Player DMP audio is 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 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.
