Setting up the RealTime Multimedia Engine connector
This section describes how to install and use Lync or Skype for Business (SFB) on a Citrix desktop.
1. Install Citrix HDX RealTime Connector on Citrix desktop VDA/Server. HDX RealTime Multimedia Engine (RTME) is the
package installed on ThinOS. It is HDX RealTime Connector that needs to be installed or upgraded on the remote server and
VDA.
NOTE: The following are applicable to RTME 1.8 only:
● You can upgrade from RTME version 1.7 to 1.8. For more information, see the Citrix documentation at
docs.citrix.com.
● The Firewall configuration is required on remote server and VDA. For more information, see the Citrix documentation
at docs.citrix.com.
● The RTME 1.8 feature on ThinOS supports only HDX RealTime Connector 1.8 due to Citrix limitation.
2. Update the ThinOS firmware, and install the RTME.i386.pkg on the ThinOS client.
NOTE: Since ThinOS 8.3.1 HF release, the RTME 1.8 and 2.1 co-exist in the release package, supporting both versions
of RTME connectors. In every ThinOS release, the RTME version may be updated to newer version and the latest RTME
version co-exists with RTME 1.8 version in the corresponding release packages.
3. (This step is for RTME 1.8 only) Configure the Domain Name Server (DNS) settings on ThinOS for Lync Server.
NOTE: You must ensure that the thin client does not have USB redirection for video/audio devices in order to have
RTME working correctly.
4. Log in to your Citrix Desktop, and sign in to Lync client or Skype for Business (SFB) client.
● For RTME 1.8, the RTME icon is displayed in the lower-left corner of the Lync client window.
● For RTME 2.x, the RTME icon is displayed on taskbar.
