44 GE Information D.20 RIO - HARDWARE USER’S MANUALONLINE HMI CHAPTER 4: SETTING UP THE D.20 RIOConfigure time synchronizationThe Configure Time Sync menu allows you set the D.20 RIO’s internal date and time aswell as modify options associated with time synchronization.Set system clock Enter the current calendar date and time of day. The value entered will be recorded in theD.20 RIO.Set system time zone Enter the time zone of the D.20 RIO.Time sync input Configures the D.20 RIO to use SNTP to calibrate the system clock. Enter the IP address ofthe SNTP server and select the polling Interval. Use a D400 as the SNTP source and thedefault of 5 seconds to ensure accurate event timing.NOTEA D400 is the only recommended SNTP time source for a D.20 RIO since the D.20 RIO usescustom SNTP communication with a D400 to achieve better system time accuracy. Inaddition, to achieve better accuracy, there can be no more than 3 Ethernet switches, hubsand/or routers between a D.20 RIO and D400; both the D.20 RIO and D400 must beconfigured for VLAN.HardwareThe Hardware menu allows you to view the serial number associated with your D.20 RIOdevice.Reset System LogsThe Reset System Logs menu allows you to check the size of, and delete archived andcurrent D.20 RIO logs.Online HMIThe D.20 RIO includes a web-based HMI (human machine interface). The online HMI is yourwindow into the D.20 RIO. Through the HMI you can monitor the status of your substationnetwork, view data, configure peripheral devices, and change the device set-up.Depending on how it is configured, the D.20 RIO is protected by a secure HTTPS orstandard HTTP connection that requires a user name and password.For more information on the D.20 RIO HMI, refer to the online Help once you have loggedin.The D.20 RIO HMI is based on the web-based programming language Java. The Webbrowser must be equipped with a plug-in that supports Java. The D.20 RIO is designed tooperate with version 6.0 (or later) of Internet Explorer®. If you are using Internet Explorer,version 6.0 or later you may need to install the J2SE® Runtime Environment (JRE). You musthave the JRE Version 6.0 (or later) installed and enabled on your PC to operate the D.20 RIOHMI. When you log into the D.20 RIO, the device automatically detects if your Web browserhas the JRE installed. If not, the JVM Detection window gives choices for installing the JRE.
