Polycom video conferencing how to deal with no signal output – Technology, Video Conference System – Education Industry
Polycom VSX series video conferencing system terminal equipment in the process of installation is often such a problem?? Video signal can not be displayed.
Many direct users and even dealers and system integrators the treatment of this issue feel very difficult, the general began to check the complete display device ( Projector , Plasma, LCD TV ) Signal input is normal. For example, a display device Power supply Whether to open; display signal switching whether to switch to the INPUT signal corresponding to the current video conferencing mode (usually S-video or VGA mode).
Next, check our Polycom video conferencing video signal output OUTPUT lines are not connected to install in place, there is a general line of VGA cable and the S terminal output of two ways. In the Polycom Office, the host backplane output interface to display input output interfaces, the general use of Polycom original video signal cable. We must ensure that the root line of the signal is unblocked. This will reduce the video conference generated during the installation of unnecessary trouble. If Polycom video conference with integrators Decoration This process, we arranged ahead of time the video signal line, we need to make VGA and S terminals of the connector.
Both Shanghai Dragon Electronic S in this sorted out and the VGA terminal line order to help integrators used in the construction of the wiring.
S-VIDEO or S terminal of the line sequence:
VGA HD15 line that order: When we exclude other methods determined by the video signal and display devices are connected in the normal, and Polycom video conferencing terminal case of power at startup or not the words of the video signal output. We then need to Polycom audio and video output interface to find the problem.
Whether Polycom VSX5000 or VSX6000 and VSX7000S, we found the back of the device there are many audio and video input and output interfaces. This time, how do we ensure that we connect the video output interface, it is correct. Polycom generally have two outputs, for example take VSX7000S. Back with S terminal and VGA output. We can choose the main output terminals S also allows VGA as the main output. Of course, this must be transferred out of the video signal so to do within the system set to deal with.
If we use this time is the Polycom S terminal as the main output, and display devices are all connected under normal conditions or not the video signal output we can conclude that because the system in default of the VGA signal interface as a Polycom video the main output of the signal, and the system, the second video output is not open, it happens. This time we offer a simple way, by using the Polycom remote control to operate. (This is the Polycom little secret Oh) on the Polycom system integrators generally useful Oh. Mode of operation (Note a): first the machine off, and then holding the remote control toward the Polycom video conferencing remote host Anzhe the lower left corner of the "well" was key to boot, until you hear the startup sound and the display background screen appears date.
Similarly, when Polycom video output to connect the VGA cable as the main output of Polycom video conferencing, and the display device does not show it is possible that the S terminal is the system default as the main outputs of the Polycom video. We need to do is close the Polycom video conference host, following the remote control "*" key to boot until the meter number sounds and images.
Course into the system, if you want to use the dual display function, or your Polycom equipment has dual display function, and has two display device, we can also open two way video signal output. Method: using Polycom remote location in the main menu, enter the system?? Management settings?? Monitors ?? Monitor 2 to open
