Hi HC,
Regarding your question about TimeSync, the diagram you attached is not an ICN network. What we define as an ICN network is a dedicated patient monitoring network WITH a central station. The diagram you attached does not have a central station, and therefore, not an ICN network.
In such a non-ICN network, the XDS can sync all monitors on the network to the PC clock on the Master XDS. The PC clock can then be set to sync with your hospital's NTP server. You don't need to do any special configuration in order to use TimeSYnc - this service is started automatically on the XDS PC that you have designated as the Master XDS.
On an ICN network, the central station provides the TimeSync service, and therefore, XDS will automatically disable its own TimeSync service.
