Using Multiple CTP20s for Collaboration

In a meeting room, you can use multiple CTP20s for whiteboard collaboration or presentation. Up to 4 CTP20s can be
connected to a VCS codec simultaneously.
The collaboration methods are as below:
Status Synchronizing: The status of the VCS codec can be synchronized to all connected CTP20s.
•
• Configuration Synchronizing: in idle state, you can configure the VCS codec via each CTP20, and the new
configuration will cover the old configuration and take effect immediately.
Whiteboard Collaboration: you can use each CTP20 to initiate the whiteboard collaboration which can be
•
received by other CTP20s simultaneously, but the editing and noting on each CTP20 are independent. If you close
the whiteboard of one CTP20 connected to a VCS codec, the whiteboards of other connected CTP20s are closed
simultaneously.
Presentation Collaboration: if you enable the feature of auto-presentation on devices, after you start presenting
•
on the local computer/Apple devices, the presentation will be synchronized to all the CTP20s, but the editing
and noting on each CTP20 are independent. If you do not enable the feature of auto-presentation on devices, you
can initiate the presentation on any CTP20 and the presentation will be synchronized to all the CTP20s, but the
editing and noting on each CTP20 are independent. If you close the presentation on one CTP20 connected to a
VCS codec, the presentation on other connected CTP20s are closed simultaneously.
Note: If multiple CTP20s are wired to the VCS codec, you need a multi-port switch.

Using VCM34

To further improve the sound quality, you can connect VCM34 to the VCS codec. If you need to expand the
pickup range, you can connect to multiple VCM34s in cascade (up to 4 VCM34s). For more information, refer to
Yealink_VCM34_Quick_Start_Guide.

Exporting or Importing Configuration Files
You can export the configuration files to check the current configuration of the system and to troubleshoot if
necessary. You can also import configuration files for a quick and easy configuration. The format of the imported
configuration file must be "*.bin".
