Audience
 

We prepared this material with specific expectations of you.

You manage and operate presentation systems that are connected to remote DMP endpoints.

Concepts

Overview

A DMP transmits signals to a public presentation system that you choose, such as a flat-panel display or projector that is connected to the DMP.

• This system might use projection or display technologies that are analog or digital.

• It might support Standard Definition (SD), High Definition (HD), or both.

• Its output fidelity depends in part upon which signal cables (and adapters) connect it to your DMP.

– With most modern, digital presentation systems, you can use an HDMI cable for both video and audio. Other such systems — including the 40-inch and 52-inch models in our LCD Professional Series — might not connect until you combine the HDMI cable with an HDMI-to-DVI adapter for video. However, DVI does not support the transmission of audio signals. In this case, you can use the provided audio cable for audio.

– When you use a Cisco-branded LCD display, a feature of Cisco Digital Signs software can detect automatically when your display is turned On or Off. To connect one of these models to your DMP, you must use an RS-232 serial cable in addition to the video signal cable.

Our centralized management features help you to manage a global IP network of digital signs for any purpose — in conference rooms, public venues, or executive offices.

Understand Which Displays Work Best with DMPs

We certify that DMPs work as designed with Cisco LCD flat-screen displays. All displays in this series are engineered for intensive use in public settings. See their technical documentation (CSCti35199) at http://cisco.com/en/US/products/ps10099/tsd_products_support_series_home.html .

 

In most cases, DMPs can use displays that comply with modern, international standards. We recommend the following if you must use a third-party display.

• Digital, not analog.

• High-definition, not standard-definition.

• Professional-grade, not consumer-grade. Digital signs and public IPTV installations run many more hours each day than a consumer-grade display is engineered to run. A consumer-grade system is likely to fail years sooner than a professional-grade system would under these circumstances.

• LCD, not plasma. Digital signage uses static images more often than it uses full-motion video. Most often, content is web-based or animated in Flash. The nature of these media types means that some pixels are not updated frequently in digital signage. LCDs are less susceptible to burn-in than plasma displays are. Even though image persistence is sometimes a problem on LCD displays, it is almost always self-correcting and is unlikely to occur when you follow manufacturer guidelines for managing your displays correctly.

  • Built-in support for RS-232 signalling. This recommendation is important in direct proportion to the number of displays that you will manage.

Understand How to Choose Media Signal Cables

Caution Poorly shielded cable can sometimes promote undesired signal leakage (egress), interference from over-the-air signals (ingress), or crosstalk between cables that are in close physical proximity.

Special considerations apply when you obtain a signal cable that is longer or of a different type than cables that we included in your product kit. For DMP models that support the following signal cable types, the maximum supported lengths are:

• Composite — 10 ft (approximately 3 m)

• HDMI 1.1 — 16 ft (approximately 5 m)

• RCA — 10 ft (approximately 3 m)

• S-Video — 10 ft (approximately 3 m)

  • SPDIF — 10 ft (approximately 3 m)

Note • When image signals are transmitted through a composite cable, image quality suffers. When you use a composite cable and your DMP shows any web-based media, small text might be difficult to read in TVzilla (the web browser that runs on some DMP models). To work around this limitation, you can lower the browser resolution setting in DMPDM.

  • Shockwave Flash (SWF) text is blurred during playback when a component video cable connects your DMP to its presentation system (CSCsx48899). To work around this limitation, avoid the use of component video cable.

 

Cable Quality

The best signal cables objectively are those with the lowest signal resistance. Factors that affect signal resistance include wire gauge, cable shielding quality, and cable connector quality. However, the same materials and engineering designs that reduce signal resistance add to the cost of manufacturing. This added cost is passed along to a consumer. So, it is useful to understand when signal resistance is not relevant. Knowing this can help you to manage and reduce expenses without necessarily lowering your standards. High cost is not inevitable. Nor is it proof of high quality. Sometimes, in fact, high quality (low signal resistance) is irrelevant.

Even mediocre signal cables are sometimes sufficient, and such cables are often very affordable. Figure 16-1 illustrates the most important factors to consider when you choose signal cables.

Figure 16-1 Signal Cable Purchasing Factors to Consider

 

Beyond the general guidelines that Figure 16-1 illustrates, two additional factors might constrain which types of signal cable you can use.

• The technology, brand, and model of your display — Check its product documentation to understand its compatibility with various signal cable types.

Understand and Prevent Image Retention (Burn-in)

After any LCD panel shows a fixed pattern for more than 12 hours, slight voltage differences can develop among electrodes that power the liquid crystals. Therefore, after you show a fixed image for an extended period of time, it might become blurred or might leave a residual image on an LCD display. This occurs when charged liquid crystal becomes “stuck” in one position.

Nonetheless, image retention should not occur when you follow our recommended best practices.

Turn off your display at regular intervals
  • After using your display for 20 hours, turn it off for 4 hours.
  • After using your display for 12 hours, turn it off for 2 hours.
Rotate colors and color schemes at regular intervals

Cycle between colors every 30 minutes.
Avoid extreme differences in luminance
  • Do not use foreground and background colors that differ greatly in their luminance.
  • Do not use gray.
  • Use bright colors that are identical in their luminance or that differ only slightly in their luminance.
  • Apply motion every 30 minutes to regions that show text.
  • Apply 1 minute of motion to any region that has shown a logo for 4 hours.
Use built-in features to prevent image retention
 Tip Some Cisco LCD models support these features while others do not. Check your Cisco LCD documentation.
  • Use the Scroll feature to move a solid black bar up and down the display.

– Set its interval in the rage from 1 to 10 hours. We recommend a 1-hour interval.

– Set its duration in the range from 1 to 5 seconds. We recommend a 5-second duration.

 

  • Use the Pixel Shift feature to move a dotted black rectangle from top to bottom.

– Set its interval in the rage from 1 to 10 hour. We recommend a 1-hour interval.

– Set its duration in the range from 10 to 50 seconds. We recommend a 50-second duration.

 

  • Use the Bar feature to move a black crosshair around your display.

– Set its interval in the range from 1 to 10 hours. We recommend a 1-hour interval.

– Set its duration in the range from 10 to 50 seconds. We recommend a 50-second duration.

Procedures

• Connect to a Digital Display or Projector

• Connect to a Touchscreen

• Connect to an Analog Display or Projector

• Prepare Cisco Displays to Support RS-232 Syntax

• Use Predefined Tasks to Configure and Manage Equipment

Connect to a Digital Display or Projector

Timesaver Is your display a touchscreen? If so, this topic is not for you. Instead, see the “Connect to a Touchscreen” section.

HDMI and DVI differ in their support for audio signals and use connectors that are shaped differently, but otherwise are identical. Thus, an adapter can help you to connect to your DMP any presentation system that supports DVI but not HDMI. When you do this, however, you must also use a separate, additional signal cable to transmit audio signals, or playback will be silent.

Tip Is playback silent even though your signal cable type is HDMI? If so, make sure that your DMP has attributed an authentically HDMI-standard resolution value — such as “HDMI_1080p60” — to your presentation system (CSCsk29797). The HDMI standard does not support audio playback through any system whose settings ignore or contradict HDMI standards. Thus, you cannot use HDMI to play audio through a presentation system whose resolution setting is, for example, “VESA_1360x768x60.”

Before You Begin

• Obtain an HDMI-to-DVI adapter if your presentation system uses DVI.

Procedure

Step 1 Do only one of the following.

  • Does your presentation system
    use HDMI?

When you will use HDMI

a. Connect the HDMI cable to the HDMI interface on the back panel of your DMP.

b. Connect the other end of the cable to your presentation system.

c. Procced to Step 2.
  • Does your presentation system
    use DVI?

When you will use DVI

a. Connect the HDMI cable to the HDMI interface on the back panel of your DMP.

b. Fasten an HDMI-to-‘DVI adapter to the free end of the cable.

c. Connect the free end of the DVI adapter to the corresponding interface on your presentation system.

d. Plug the 3.5mm audio jack into the Audio interface on the back panel of your DMP.

e. Connect the other end of the audio cable to the corresponding interface on your presentation system.

f. Pproceed to Step 2.

Step 2 If the presentation system is not already turned on, turn it On now.

Step 3 Stop. You have completed this procedure.

Connect to a Touchscreen

Tip Some touchscreens work as designed only after they are calibrated manually. If your touchscreen is one of these, its calibration occurs during a later stage of DMP setup. The list of related topics for this procedure states where you can learn about calibration.

DMP connections to a touchscreen are mostly the same as for other digital displays. However, touchscreens employ a special cable that supports interactivity through touch. This might be either an RS-232 serial cable or a USB cable, depending on the touchscreen model. Although some models support both cable types for interactivity, you can use only one type at a time.

Before You Begin

• Verify that your DMP model supports touchscreen technologies and that we support the touchscreen brand, model, and device driver that you will use.

  • Check the documentation for your touchscreen to learn whether it requires a serial connection or a USB connection to your DMP, or if it supports both.

Procedure

Step 1 Do only one of the following.

  • Does your touchscreen use HDMI?

When you will use HDMI

a. Connect the HDMI cable to the HDMI interface on the back panel of your DMP.

b. Connect the other end of the cable to your touchscreen.

c. Proceed to Step 2.
  • Does your touchscreen use DVI?

When you will use DVI

a. Connect the HDMI cable to the HDMI interface on the back panel of your DMP.

b. Fasten an HDMI-to-DVI adapter to the free end of the cable.

c. Connect the free end of the DVI adapter to the corresponding interface on your touchscreen.

d. Plug the 3.5mm audio jack into the Audio interface on the back panel of your DMP.

e. Connect the other end of the audio cable to the corresponding interface on your touchscreen.

f. Proceed to Step 2.

Step 2 Do only one of the following.

  • Does your touchscreen use USB?

When touchscreen interaction relies on USB

a. Connect a USB cable to the USB interface on the back panel of your DMP.

b. Connect the other end of the cable to your touchscreen.

c. Proceed to Step 3.

 

Note If your DMP model has only one USB connector, you might prefer to connect an external hard drive there for added local storage. In this case, an RS-232 serial cable would be the better choice for connecting a touchscreen to your DMP.
  • Does your touchscreen use RS-232?

When touchscreen interaction relies on RS-232

a. Connect an RS-232 serial cable to the RS232 interface on the back panel of your DMP.

b. Connect the other end of the cable to your touchscreen.

c. Proceed to Step 3.

Step 3 Turn On the touchscreen.

Tip Does a message on the touchscreen say that it must download a “characterization” file? This happens only when your touchscreen uses technologies from Elo TouchSystems and when you have never turned it On previously (or after its CF card is reformatted). When you see this message, please disregard it. The touchscreen will obtain its characterization file automatically during a later stage of DMP setup.

Step 4 Stop. You have completed this procedure.

Connect to an Analog Display or Projector

Tip DMPs support connections to analog presentation systems. However, we recommend strongly that you use digital presentation systems whenever possible.

Procedure

Step 1 Make connections for video.

a. Plug one yellow jack from the RCA video cable into the CVBS interface on the back panel of your DMP.

b. Connect the free end of this cable to the corresponding interface on your presentation system.

Step 2 Make connections for audio.

a. Plug the 3mm jack on the RCA audio cable into the AUDIO interface on the back panel of your DMP.

b. Connect the free end of this cable to the corresponding interface on your presentation system.

Step 3 If the presentation system is not already turned on, turn it On now.

Step 4 Stop. You have completed this procedure.

Use RS-232 Signals to Control Presentation Systems

No international agency exists to tell all of the world’s video equipment manufacturers which commands and methods (such as RS-232) a presentation system must support. Likewise, no global authority exists to state exactly which hexadecimal string — if any — must invoke a particular command.

So when manufacturers implement RS-232 commands, they do so as they see fit. Thus, RS-232 command syntax differs among manufacturers and sometimes differs even among equipment models that share a manufacturer in common.

Tip Check the manufacturer’s product documentation for your LCD display to learn about its RS-232 support and syntax.

So, how is RS-232 useful to me?

Your digital signs run in the real world because your organization expects to tell someone something. But when you, the administrator, are half a world away from a sign, or even just a few buildings away, how can you be absolutely sure that your sign is doing anything — let alone everything — correctly?

 

• Is its power turned Off when it should be turned On?

• Is its audio muted during an exclusive musical performance?

  • Does it ignore a valid video input signal while listening on some other, but disconnected, interface?

 

Meanwhile, how can you recognize and fix any such misconfiguration from miles away? Situations like these are perfect for RS-232, whose technology passes properly constructed “command-and-control” instructions through a DMP and into its attached presentation system.

A case in point: Cisco Digital Signs software can tell you automatically and in real-time which of your centrally managed Cisco LCD displays are turned On or Off. You can learn at a glance when one (or more) of these remote units is in the wrong power state, and then issue a simple command to correct the mistake. But even so, your ability to turn remote equipment On or Off so easily through the Internet is just one benefit of feeding RS-232 commands through a DMP to its attached LCD display.

This section includes these topics.

Prepare Cisco Displays to Support RS-232 Syntax

Individual Cisco LCD display models each support dozens of RS-232 commands, covering the range of their configurable features.

This topic explains various steps that you must complete before a Cisco LCD display supports RS-232 signaling for centralized management.

Before You Begin

• Connect your Cisco LCD display to the DMP that will drive it.

  • Plug in your LCD display and turn it On.

Procedure

Step 1 Choose Digital Media Players > DMP Manager .

Step 2 Use one of these methods, at your discretion, to limit the scope of what the DMP List table shows to you.

  • Limit the scope by filtering.
(Optional)
When you will filter against an attribute value

a. Choose a DMP attribute type from the Filter list.

You can filter by DMP name, description, IP address, MAC address, or any other supported attribute.

b. Enter an actual value to filter against the attribute type that you chose.

Had you chosen to filter against the Description attribute, for example, you might now enter a word like ‘ classroom ’ or ‘ billboard ’ as the value to match.

c. Click Go .

d. Proceed to Step 3.

 
  • Limit the scope by browsing.
(Optional)
When you will browse by DMP group

a. Browse in the DMP Groups tree to restrict what the DMP List table shows.

b. Proceed to Step 3.

Step 3 Click one DMP in the table to choose it exclusively.

OR

Use check boxes to choose multiple DMPs whose attached presentation systems are all identical.

Step 4 Click , above the DMP List table.

Step 5 Click RS-232: Control supported, non-DMTech displays in the System Tasks drawer.

Step 6 Click OK .

A message loads under the DMP Manager tab, confirming that DMM received your submission.

Step 7 Choose Digital Media Players > Advanced Tasks > DMP Polling Status Control .

Step 8 Click Add New Application .

a. Choose your Cisco Professional Series LCD display model from the TV Type list.

Note This variation of our standard TV Type list includes Cisco models exclusively. These are the only presentation system models whose electrical power On/Off state this Cisco DMS release can poll in real-time.

ALSO: Is your Cisco LCD display the 32-inch model? If so, see the ““ section, elsewhere in this procedure. It might be necessary for you to disable a feature that all other users enable.

b. Choose On from the Polling list, and then click Submit .

We generate a concise name for this application automatically. We are able to do this because your selections have already defined the purpose and scope of your new polling control application. Its generated name is always one of these:

  • CISCO_32N=on
  • CISCO_40N=on
  • CISCO_42L=on
  • CISCO_47L=on
  • CISCO_52S=on
  • CISCO_55Q=on

 

After we show the name to you, your new polling control application is ready for use.

 

Step 9 Click , again.

Step 10 Click DMP Polling Status Control in the Advanced Tasks drawer.

Step 11 Click the same “ =on ” application that you saved for your Cisco LCD model, and then click OK .

A message loads under the DMP Manager tab, confirming that DMM received your submission.

Note As many as 5 minutes might pass before the LCD Status column updates its value to show the real-time power state of your Cisco LCD display. Ultimately, this value will say either “Display On” or “Display Off.” Until then, however, it will say “Not Set.”

Please check the next step in this procedure, however, to learn if another step is necessary here to configure your LCD Professional Series model.

Step 12 Compensate, as needed, for model-specific exceptions to basic RS-232 setup.

  • Do you use our 42-inch or 47-inch LCD display?
When you will poll the On/Off status of a 42- or 47-inch Cisco LCD display

Factory-default settings for this equipment save power by turning Off most of its support for remote management and polling. Almost any attempt to use such features can fail while the energy-saving settings remain in effect.1 So, before you can reliably manage or poll this equipment from Cisco DMS, YOU2 MUST explicitly prepare the RS-232 service for use. Later, at your discretion, you can either turn Off3 this support or leave it turned On4 continuously.

 

a. Press Menu on the handheld remote control unit.

Your LCD display shows its OSD menu.

b. Use buttons on the remote control to choose Option > Set > Set ID , and then change the Set ID value (from “Off”) to 1 .

c. Press Exit on the remote control.

FAQs About Cleaning and Maintenance

• How should I clean and maintain a Professional Series display?

Q. How should I clean and maintain a Professional Series display?

For cleaning and maintenance guidelines, see the Safety Instructions section called “Cleaning the Display, Its Plug, and Its Outlet Safely” in User Guide for Cisco LCD Professional Series Displays on Cisco.com.

FAQs About Daily Operation

• How long does display autodetection take?

• Why might display autodetection fail?

Q. How long does display autodetection take?

Autodetection takes less than 8 seconds in most cases and less than 2 seconds in some cases.

Q. Why might display autodetection fail?

The display autodetection feature fails unless you use an HDMI signal cable (with or without a DVI adapter) to connect a presentation system to your DMP.

FAQs About RS-232

• Why does my DMP 4400G run very slowly while its RS-232 features are enabled?

Q. Why does my DMP 4400G run very slowly while its RS-232 features are enabled?

The likeliest explanation is that your signal cable is faulty. Try substituting the equivalent cable from a DMP that operates as expected when RS-232 features are enabled. If doing this has no effect, restore your DMP to its factory-default settings and then configure it once more to support RS-232.

FAQs About Touchscreens

• What should I do when a message states that my touchscreen must download a characterization file?

• When is it necessary to repeat the calibration of a touchscreen?

• What can cause a properly calibrated touchscreen to operate as if it is not calibrated?

Q. What should I do when a message states that my touchscreen must download a characterization file?

Do not disturb or interrupt the automated process. It occurs only once, and takes approximately 10 minutes to finish. When it is finished, your touchscreen will clear the message automatically.

Q. When is it necessary to repeat the calibration of a touchscreen?

You must repeat this calibration whenever you:

  • Rotate a touchscreen or change its resolution.
  • Replace a touchscreen.

Q. What can cause a properly calibrated touchscreen to operate as if it is not calibrated?

If this happens to you, unplug the serial cable (or USB cable) that connects this touchscreen to your DMP. Then, plug that cable back in again.

FAQs About Product Quality

• Why are some pixels unexpectedly bright, or black?

 

Q. Why are some pixels unexpectedly bright, or black?

Cisco LCD displays use advanced semiconductor technology with extremely high precision. Nonetheless, the red, green, blue and white pixels might seem unexpectedly bright sometimes, or you might notice some black pixels. This is not the result of low quality or a malfunction and you can continue to use your display without incident.

Troubleshoot the Power Indicator

Problem The screen is blank AND the power indicator is off.

Solution Ensure that the power cord is firmly connected and the display is turned on.

Problem The power indicator blinks.

Solution Wait for less than 1 minute. The display is saving changes made to its settings.

Troubleshoot Image Quality

Problem A message states, “Check Signal Cable.”

Solution Make sure that the:

  • Signal cable is firmly connected to the video sources.
  • Video sources are turned on.

Problem The image rolls vertically.

Solution Make sure that the signal cable is securely connected.

Problem The image is intermittently black (CSCtw78742; CSCts83613).

Solution Avoid incompatible combinations.

  • Have you used a DVI connector while our HDMI resolution autodetect feature was enabled on your DMP? And then, was the reported resolution called “1920 x 1080?” If so, you must disable the autodetection feature. Cisco DMP models support DVI connections only in combination with VESA-standard resolution values — and VESA standards do not include “1920 x 1080.” Instead, their equivalent is called “VESA_1080p.” You must choose and apply this resolution value manually.
  • Do not enable HDMI autodetection with a display whose resolution is “DVI_1920p.”
  • Disable our HDMI resolution autodetect feature on your DMP when it reports that any 1080p presentation system characterizes its resolution as “VESA_1080p.” Then, impose the resolution value manually that DMPs use: “HDMI_1080p.”

Problem The image is blurred.

Solution Try these possible workarounds.

• Run Frequency Coarse and Fine tuning.

• Turn Off the display, remove its accessories and signal cables, and then turn it On again.

• Set the resolution and frequency to the recommended ranges.

Problem The image is too light OR too dark.

Solution Adjust the brightness and contrast.

Problem Colors are not consistent, OR shadows are too dark, OR white areas are too white.

Solution Adjust the color.

 

Troubleshoot Audio Quality

Problem Sound is too quiet OR is not audible.

Solution Check the volume level.

Problem Sound frequency is too high OR too low.

Solution Check the levels for treble and bass.

Troubleshoot the Handheld Remote Control Unit

Problem Buttons do not respond.

Solution Check...

• Battery polarities (+/-).
• If batteries have lost their charge.
• If the power is turned On.
• If the power cord is connected securely.
• If a fluorescent or neon lamp is turned On nearby.

Note When you use Digital Signs to lock your remote control and the front panel controls for your display, the remote control cannot unlock them. Instead, you must switch the Safety Lock, Remote Control Lock, and Panel Lock toggles all to Off in Digital Signs.

Note When you use Digital Signs to lock your remote control, the remote control cannot unlock itself. Instead, you must switch the Safety Lock and Remote Control Lock toggles both to Off in Digital Signs.
