Use a Connection that Combines HDMI with DVI
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 signal cable to transmit audio signals, or there will not be any audio.
Before You Begin
-
Obtain an HDMI-to-DVI adapter.
Procedure
Step 1 Make connections for video:
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.
Step 2 Make connections for audio:
a. Plug the 3.5mm audio jack into the
Audio
interface on the back panel of your DMP.
b. Connect the other end of the audio 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.

Work Around the Low Signal Quality of Composite Video Cables
Note Image quality suffers in visual media when the signals that describe them are transmitted through a composite cable. When you use a composite cable and your DMP shows any web-based media, small text might be difficult to read in TVzilla. To work around this limitation, you can lower the browser resolution setting in DMPDM.

Connect to a Touchscreen
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 of these cable types for interactivity, you can use only one of them at a time.
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.
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. See
http://www.cisco.com/go/dms/compatibility
.
-
Check the documentation for your touchscreen to learn if it requires a serial connection or a USB connection to your DMP, or if it supports both of these connection types.
Procedure
Step 1 Connect an HDMI cable to the
HDMI
interface on the back panel of your DMP.
Step 2 Connect the other end to your touchscreen.
OR
If your touchscreen supports DVI connections and not HDMI connections:
-
Fasten an HDMI-to-DVI adapter to the free end of the cable.
-
Connect the free end of the DVI adapter to the corresponding interface on your touchscreen.
Tip You can use an HDMI splitter or other supported method to attach multiple presentation systems to your DMP, but only one of these systems can be a touchscreen.
Step 3 Do only one of the following:
-
Connect a USB cable to the
USB
interface on the back panel of your DMP. Then, connect the other end to your touchscreen.
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.
-
Connect an RS-232 serial cable to the
RS232
interface on the back panel of your DMP. Then, connect the other end to your touchscreen.
Step 4 Turn
On
the touchscreen.
A message might appear on the touchscreen, to inform you that it must download a characterization file. This happens only if your touchscreen uses technologies from Elo TouchSystems and if 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.
Tip When you turn On a touchscreen that was calibrated previously, it might sometimes appear not to have been calibrated. If this happens to you, unplug the serial cable or the USB cable that connects this touchscreen to your DMP, and then plug that cable back in again.
Step 5 Stop. You have completed this procedure.
Choose and Calibrate a Touchscreen Driver
This procedure applies to you only if your DMP supports interactivity through touch and your presentation system is a touchscreen. Furthermore, it assumes that you completed the “Connect to a Touchscreen” section.
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. See
http://www.cisco.com/go/dms/compatibility
.
-
Log in to DMPDM.
Procedure
Step 1 If your touchscreen shows a message that says it must download a touchscreen characterization file:
• Do not disturb or interrupt this process. It occurs only once, automatically.
• The process takes approximately 10 minutes to finish. When it is finished, your touchscreen will clear the message automatically.
-
Stop. You have completed this procedure and there is no need to perform any of its other steps.
Step 2 Because some touchscreen drivers cannot be calibrated on a DMP while it is playing video, use DMPDM to stop all videos.

in the Settings list.
Tip If you do not see this option in DMPDM, your DMP might not support this feature. If you believe that its hardware design allows for the possibility of such support, check whether any firmware upgrade is available for your DMP that adds support for this feature:
• Cisco DMS release notes — http://cisco.com/go/dms/releasenotes.
• Cisco DMS compatibility information — http://cisco.com/go/dms/compatibility.
If such firmware is available, obtain it and then complete the DMP firmware upgrade procedure in the DMPDM user guide at http://cisco.com/go/dms/dmpdm. The nature of your Cisco DMS service contract might limit:
• Which upgrades are available to you.
• Where and how you obtain upgrades.
• Whether you must pay anything to obtain upgrades.
To learn about Cisco service contracts, see http://cisco.com/go/cscc.
a. Check the Currently Loaded Driver row to see which touchscreen driver, if any, is active on your DMP.
The driver might be
3M
,
Zytronic
,
Elo
,
GeneralTouch
, or possibly something else. As we test various drivers, we might update this list between any two DMPDM releases.
Your DMP must use a driver that is compatible with your touchscreen.
b. If the active driver is not compatible with your touchscreen, choose the compatible driver from the Choose Touch Screen to Activate list.
c. Click
Apply
.
d. Click
Save Configuration
in the Administration list, and then click
Save
.
e. Click
Restart DMP
in the Administration list, and then click

Step 6 If you chose 3M, Zytronic, or another driver that must be calibrated manually:
a. After your DMP has restarted, log in again to DMPDM.
b. Click
Touch Screens
in the Settings list.
c. Click
Calibrate
<
driver_name
>
Screen
, where
driver_name
is the name of the driver that you chose.
-
When messages appear on the touchscreen surface that prompt you to touch the surface in various places, follow the prompts exactly. For example, the calibration utility might prompt you to touch exactly five areas or exactly nine areas.
-
If you do not complete this exercise within the brief period that is allotted for it, the calibration utility times out automatically.
-
Repeat these steps for manual calibration if the driver utility times out before you can calibrate your driver.
Note You must repeat the calibration whenever you:
-
Rotate a touchscreen or change its resolution.
-
Replace a touchscreen.

Procedure
Step 1 Click
DMP Display Attributes
in the Settings list.
The display autodetection feature is enabled by default. However, it fails unless you use either:
-
An HDMI signal cable.
-
An HDMI signal cable in combination with an HDMI-to-DVI adapter.
Note If you are satisfied with the choices and entries that DMPDM made for you as a result of its DMP display autodetection, you are done with this section and you can go now to the .
Otherwise, if you are not satisfied — or if your display does not support HDMI connections — do the following.
a. Choose
Disable
from the DMP Display Autodetection (requires HDMI) list.
b. Choose a standard from the Display Standard list that applies in your country. For example, even though our factory default selection is NTSC_M, your country might use
PAL
instead.
c. Choose your connector and signal type from the Interface (DMP display output) list. For example, you might use
SVIDEO
.
If you do not know which options to choose, see the manufacturer documentation for your presentation system.
Step 2 Choose from the Color Space list the absolute color space that your presentation system uses.
Step 3 (
If you chose RGB as the color space
) Choose an option from the Color Component Order list to define the order in which to store red, green, and blue data.
The color component order is sometimes called the left-to-right additive color model.
Step 4 (
Optional
) Move any or all of the sliders to compensate for presentation system deficiencies in video (brightness, contrast, or saturation) or audio (channel volume).
Step 5 Click
Apply
to confirm your choices and to implement them until you change them or until you restart your DMP.
