If the PC has an internet connection, the current time and date information can be checked
by clicking the Get Time button. A browser window will launch which will display the current
time and date (in several time zones) retrieved from the US Naval Observatory website. To
update the displayed information on the browser, click the Refresh button. The PC must be
connected to the internet for this function to work. Use the given information to update the
time and date of the PC and the field units.
The Day Change Hour is optional because you may wish to have different Day Change
Hours for each individual unit. It will not be sent to the selected units unless the check box
under Day Change is activated. Activating the check box will instruct Sentinel to send the
Day Change Hour information. You can change the Day Change hour by scrolling through
the desired Hour using the Up and Down arrows next to the text box.
After completing the information update, click the Send button. Sentinel will then transmit the displayed information to each of
the selected field units.
NOTE: Closing the Synchronize Units Time & Date window without clicking Send will not update the field unit information.
After configuring Special Data, you should click Time/Date button in the Master Control
panel to open the Time / Date screen. The time and date set in your PC will automatically
display under Central Computer. The displayed time is synchronized with the computer’s
clock. Clicking the Set PC Time button will enable you to set the computer’s time.
Click the Receive button to read the time and date from the field unit to check its accuracy.
To send the correct time and date to the field unit, click the Send button. Send is only
enabled after Receive is processed. The data in the left column is sent to the field unit,
then received back from the field unit and displayed at the right column for verification. The
Communication Progress window will appear during the data transfer, as for all
communications between the Central and a field unit.
The Schedule Reference Day is simply the date the software was first configured on your
central computer. The date can be updated at the Software Configuration screen. By
using this date as its reference, Sentinel ensures all schedules are on the same schedule week.
You can define 16 different schedules for a field unit. All 16 schedules are available
to any of the field units 16 programs. You can type a description for each schedule
in the bottom text field. To switch the view to a different schedule, click the desired
tab (1, 2, 3, etc.) at the top. Each schedule is six weeks long. Sentinel uses the
Reference Date to automatically determine the current week of each schedule.
To select a day for irrigation, click the box corresponding to the day and week. Days
selected for irrigation (Run Days) are blue with a check mark. To deactivate a day,
so no program will run that day, click it to change it back from blue to the
background color. Buttons on the left of the calendar will fill simple patterns; Daily,
Odd days, Even days, every 3rd Day or No Days. You can also click on the day
letter above the column to select the entire column or click the week number at the left to select an entire week. Double
clicking on the same letter or number will deselect that column or row. The Send button will transmit the schedules to the field
unit, which stores all Run Days for each schedule. The Receive button will retrieve all 16 schedules (four for older field units)
from the field unit. Sentinel will not save the received schedule to the database until the Save button is clicked.
NOTE: For older field units with an earlier software version which only support four schedules, the Scheduling Program
window will only display four available schedules. This is determined by the field unit firmware version received in
Special Data.
The Print button will print an image of the selected schedule on your default printer.
