Cisco TelePresence System Codec C60 Manuel de dépannage

Monitor

Checklist:

•

physical cabling – What output from the video system is being used and what input on the

screen does it connect to. Swap the cable.

•

Check that the input selected on the screen matches the connector the cable from the video

system is plugged into (C Series, SX20 only).

•

if you are using a digital connection (HDMi, DVi), the resolution of the screen should be detected

and the correct resolution set on the video system. Check that the output resolution from the

video system is a resolution supported by the screen by choosing

Status -> Video ->

Ouput.

•

Confirm that another device connected to same input on the screen is displayed correctly.

Cabling

The easiest method of troubleshooting cable issues is to swap out the suspected cable with another

standard cable. This one should be within the specifications for the type of cable used. if you are running

cables at the limits of length specifications, try a cable that is well within the specifications and has no

extenders, splitters or converters attached. Then restart all equipment.

For video issues check the video input to ensure that the codec is getting a signal from that connector

(see previous section). if there is no signal on the input where the equipment is connected and the

equipment (camera, pC, Doc Cam) has been confirmed working separately, then the cabling could

be the problem.

Presentation issues. Sending of images from attached computer

General

When you select to send a presentation, the information from the selected input will be transmitted to the

far end as a separate data stream from the main video source (camera). if you are having presentation

problems, first check that the presentation is seen locally. if it is not, check the input source selection

below to ensure the video system is set to the correct input source.

if you are sending a presentation but are having quality issues, please see the section below on settings

that may affect presentation quality.

Input Source Selection

if you have connected a computer to the video system and are having problems with sending a presen-

tation to the far-end, check to see if the presentation is visible on the video system locally. if you cannot

see the presentation locally then check the following:

•

Check that the cabling connected correctly and that the cables are working properly.

•

Ensure that the computer is set to display its output on the external output connected to the

video system.

Configuration -> System

When starting a presentation using the Touch panel, you can see which input source is selected for

the presentation and you can change the source by swiping left or right to see the alternate sources.

Generally you should see something similar to the image below, where the pC is selected for presentation.

Presentation quality

You can check the resolution and codec used for the presentation from the System Information/

Call Status screen on the Touch panel or remote control or look at the

Participants screen

current call to show more detailed information. You should see that there is information under the

Presentation section under Transmit.

Here you can see that a presentation is being sent using H.264 video codec at a resolution of 1024 x 576

at 15 fps.

Check that the default presentation source is set correctly on the video system to the correct

input.

inputs mean, scroll down the
