Time Synchronization
You can synchronize the clock on the Efficia CM Series monitor to the clock on your
hospital EHR server or HL7 interface server. If you have a Simple Network Time Protocol
(SNTP) server running in your hospital network, you can configure the monitor to
synchronize its time with that server.
Note — When connected to the Central, the Synchronization Type settings are not
available at the monitor.
• If your monitor is configured for LAN/WLAN data export, the monitor clock can be
synchronized to the clock on your EHR server, HL7 interface server, or SNTP server.
• If your monitor is configured for serial data export, the monitor clock can be
synchronized to the clock on the computer that receives the data from the monitor.
If the clock on the monitor differs from the clock on the server by more than five seconds,
the monitor automatically adjusts the date and time, unless:
• An NBP measurement is in progress; the time change occurs when the
measurement is complete.
• A patient record is recording (printing); the time change occurs after printing is
complete.
• An HL7 query command is sent to the monitor; the monitor rejects the query, the
next acknowledgment message is not accepted, and the time does not synchronize.
If the time difference is greater than 30 seconds, the following occurs:
• A low-priority technical alarm message, Date/Time Adjusted, appears and flashes in
the monitor’s message area.
Note — No audible alarm sounds with the Date/Time Adjusted alarm message. To
clear the message, press the Alarm Silence key.
• A horizontal blue line appears in the Trend records to indicate when the date/time
adjustment occurred.
• If NBP Interval mode is enabled, the monitor starts a new NBP measurement.
Enabling Time Synchronization
Use the Date/Time Settings Menu in the Systems Menu on the Admin tab to enable or
disable time synchronization and to select the synchronization type: Data Export or SNTP.
