seconds or greater, the SNTP will update the E2 time if enabled. When the E2 time is updated, an entry in Service Log is added.

If this field is set to No, the E2 clock will have to be set manually. If this field is set to Yes, SNTP support is used. Two SNTP servers are supported: Primary Time Server, and an optional Secondary Time Server.

Primary Time Server

The E2 will call up this primary server first to synchro- nize the E2 time. If the primary server fails to respond, the secondary server is used.

Enter the IP address or name of the first server the E2 should use to set the time (up to 40 characters).

Secondary Time Server

The E2 will use this secondary server if no response is received from the primary server, or if the primary server is invalid.

If desired, enter the IP address or name of the second server the E2 should use to set the time (up to 40 charac- ters).

Date Format

Dates may be presented and entered in either of two ways: month-day-year format, and day-month-year for- mat. Choose the most appropriate date format by using the

(LOOK UP) tab.

Daylight Savings Dates

The Daylight Savings Dates type determines how the

E2 will make date adjustments for daylight savings time. Use the (LOOK UP) tab to cycle through the options in each of the fields. There are four options:

•STANDARD US DLT DATES - the E2 will use the standard United States’ method of determining Daylight savings time dates. The Daylight savings time will start on the Sunday of the second week of March ever y year, and will end on the Sunday of the first week of November (Note: these are the dates recently enacted by the U.S. Congress, which went into effect in 2007).

•USER DEFINED DLT DATES - when this option is chosen, the user can specify start and end times for daylight savings, including month, week, and day settings.

•EUROPEAN UNION DLT DATES - the Euro- pean Union Daylight rules are the same as the Stan- dard US DLT Dates, with the exception that one hour must be added to the time at 1:00AM (GMT), during the last Sunday in March.

•DLT Not Used - the E2 does not make any adjust- ments to Active Time for Daylight Savings Time.

Daylight Savings Time uses GMT

This setting is only visible when Daylight Savings Dates is set to User Defined DLT Dates. If set to Yes, Daylight Savings Time uses GMT calculates the time to change from GMT and the current time zone setting. For example, if the start time is at 1:00 AM, and the time zone is +200 GMT, the time change will occur at 3:00 AM local time. Defaults to No.

Unit Location From

Sunrise and sunset times are calculated based on either zip code or latitude/longitude. If US Zip Code is chosen in the Unit Location From field, enter the zip code in which the controller is located. If outside the United States, choose Lat/Long and enter the latitude and longitude val- ues in which the controller is located. Once a value has been chosen, the controller is able to calculate the sunrise and sunset times. The Sunset output will turn ON at sun- set, and OFF at sunrise and can be connected to a lighting circuit.

Sundown

Sundown is an output that calculates when the sun sets based on latitude and longitude, and is ON when the sun sets. The user will select the Board/Controller, Point/ Application, and Input values from the  (LOOK UP) menu for each field. (When a Lighting Schedule is config- ured to use Sundown information, the Lighting Schedule application automatically connects to the Sundown out- put.)
