5.1.1 Setting the Time and Date
The WCM1800 does not provide a non volatile Real Time Clock, instead it uses NTP to set
the date and time following power up. In applications where NTP is not available, the
WCM1800 defaults to providing a simple uptime display.
To configure the NTP parameters, select the “Time and date” menu from the “System”
menu. The menu is as below:
If NTP is available, then the following parameters need to be set,
Time Zone +/-12
Since NTP uses GMT, time zone adjustment allows the
correct time to be configured wherever the units are
deployed globally.
NTP Server
Enter the IP address of the network NTP server.
According to the NTP protocol, the WCM1800 will wait for a random period of between 1
and 5 minutes before requesting an NTP update.
If NTP is not available, then the user can manually enter the time and date, however since
these are non volatile and not maintained over a power cycle it is not recommended.
5.1.2 Setting the Node Name
To enable identification of the WCM1800 it is useful to enter a meaningful name for the
unit. The node name is entered as a string of up to 32 alpha numeric characters, including
spaces.
