CTC uses the latitude and longitude to place node icons on the network-view map. To convert longitudes and latitudes given in decimal degrees to degrees, minutes, and seconds, see the “Convert Coordinates to Degrees, Minutes, and Seconds” section on page 3-28.

•Use SNTP Server—when checked, CTC uses a Simple Network Time Protocol (SNTP) server to set the date and time of the node. Using an SNTP server ensures that all ONS 15327 network nodes use the same date and time reference. The server synchronizes the node’s time during power outages or software upgrades. If you check Use SNTP Server, type the server’s IP address in the next field. If you do not use an SNTP server, complete the Date, Time, and Time Zone fields. The ONS 15327 will use these fields for alarm dates and times. You can still select a time zone if you use an SNTP server.

•Date—Type the current date.

•Time—Type the current time.

•Time Zone—Select the time zone.

Step 4 Click Apply.

CTC uses the longitude and latitude you enter on the General subtab to place node icons on the network-view map. You can obtain the longitude and latitude for cities and Zip Codes from the U.S. Census Bureau U.S. Gazetteer website (www.census.gov/cgi-bin/gazetteer). Coordinates are generally provided in decimal degrees. CTC requires that you enter coordinates in degrees, minutes, and seconds. Use the following procedure to convert coordinates.

Procedure: Convert Coordinates to Degrees, Minutes, and Seconds

Step 1 Find the location’s longitude and latitude. For example, Petaluma, California is 38.250739 N, 122.615536 W.

Step 2 Use the appropriate directional letter plus the first two digits of latitude and first three digits of longitude with no conversion. For Petaluma, this is N38 (latitude) and W122 (longitude).

Step 3 Using the unconverted longitude and latitude, multiply the number after the decimal by 60 to convert it to minutes. For example, .250739 x 60 is 15.0443, and .615536 x 60 is 36.93216. Use the whole numbers for the minutes (in the example, 15 and 36).

Step 4 Multiply the number after the decimal from Step 3 by 60 to convert it to seconds. In the example, .0443 x 60 is 2.6580, and .93216 x 60 is 55.9296. Use the whole numbers of the total (in the example, 02 and 55) for the seconds. If the whole number for either minutes or seconds is less than ten, add a zero to the left of the number, for example, 2 is entered as 02.

Step 5 Use zeros for fractional seconds, because the values are not significant for node positioning on the CTC network-view map.

Step 6 Convert the latitude, originally given in decimal degrees, to the Nddmmssfff format, where d=degrees, m=minutes, s=seconds, and f=fractional seconds. In this example, 38.257039 N = N381502000.
