Timers (DV-200)

Timers (xHyyy)

This article will guide you in setting date/day/time timers that will activate for a specific period of time.

Once configured, timers can be used as Qualifiers for any Davicom input. This allows you to configure date/day/time based automatic actions to be performed by Davicom units. For example, use timers to select different Alarm-Call Lists for weekends, holidays, night shifts, etc. or to change AM antenna patterns during specific time windows for each month of the year (without using the Davicom sunset/sunrise flag). Each timer is set individually according to its use and function.

To configure timers, click the Unit Configuration icon () then on the Flags tab select Timers.

Timers configuration dialog box

Example from image above: Although Davicom units have an automatic sunset/sunrise flag, some regulating authorities require specific monthly time windows for AM antenna pattern changes. In this example, twelve different AM antenna pattern timers have been configured, and each is valid for a 1-month period.

To configure a specific timer, select the timer ID (click the ID number) in the list section of the dialog box, set the following parameters in the lower part and then click Change.

Default Description: Long Unicode description for each timer. Maximum 30 alphanumerical Unicode characters. Refer to this article for more details.

Alternate Description: Short ASCII description for each timer. Maximum 18 alphanumerical ASCII characters.

Start Date: The start date of the period (upcoming holiday period for example) for the selected timer. Note that the timer will not necessarily be activated at all times during the period. If a specific Start Date is not pertinent, enter all zeros (wild card). Entry format is YYYY-MM-DD.

Note: If you want to set a timer for an event that will occur at the same date(s) once a year, enter 0000-MM-DD where MM is the specific month that will apply each year and DD the start date. Then, set the End Date (next field below) appropriately (exact same entry if the timer is to be activated for less than 24 hours on the same day). If you want to set a timer for an event that will occur once a month, enter 0000-00-DD where DD is the specific date that will apply each month, and then set the End Date appropriately.

Stop Date: The end date of the period for the selected timer. If the end date is indefinite, enter all zeros (wild card). Entry format is YYYY-MM-DD.

Start Time: The start time that will apply for all specified days during the period. Entry format is HH:MM where HH can be set from 00 to 23 (no AM or PM) and MM ranges from 00 to 59.

Note: There are no wild cards for the hours or minutes. If your timer is active during several days, enter 00:00 as the Start Time, and then 00:00 as the Stop Time below.

Stop Time: The end time for the selected timer. Entry format is HH:MM where HH can be set from 00 to 23 (no AM or PM) and MM ranges from 00 to 59. Enter 00:00 for continuous timers.

Days of the week: Mandatory field. Check the day(s) of the week you want the selected timer to activate. If no days are checked, the timer will never activate.

Note: If your timer activates on a specific date yearly for example, you need to check all weekdays since it will vary from year to year.

Click Change to save your settings.

To configure another timer, select the timer ID (click the number), set its parameters and then click Change.

To delete timer settings, select the appropriate timer ID (click the number) and click Delete.

Once you are done with the configuration of the timers, click OK. When asked if you wish to upgrade the Davicom’s memory, click Yes.
