The V77 ADM-1 provides three Sampling Methods. These are Command (upon

request via data commands only), Immediate (upon exiting configuration), and

Schedule (where sampling begins at a specified time). When Command Sampling

Method is selected, the V77 ADM-1 will only sample when the SAn command is

issued. One data message will be read at the programmed Sampling Rate and

Number of Samples to Average and reported to the host device for each channel

specified. The SAn command may be issued to the V77 ADM-1 in any of the three

Sampling Methods.

When Immediate Sampling Method is selected, the V77 ADM-1 will sample at the

selected Sample Rate, Sample Interval, and Number of Samples to Average

immediately after exiting the Configuration Main Menu. When Schedule Sampling

Method is selected, the V77 ADM-1 will begin sampling at the programmed Sample

Start Time. Sampling will occur at the programmed Sample Rate, Sample Interval,

and Number of Samples to Average. The Sample Start Time is programmable up to

24 hours in advance of the current (time-of-day) clock time.

IMPORTANT: If you program the V77 ADM-1 to commence sampling

after the Report Start Time, data messages are not furnished until the

Sampling Start Time is reached. Conversely, if you start sampling before the

Report Start Time, the first report will contain all data sampled and buffered

until reporting is initiated.

NOTE: When a "Command" sample is requested by entering the SAn data

command, the Reporting Method and Sampling Method currently

programmed are overridden and a single data message is read and reported.

Multiple SAn commands may be entered before returning to self-reporting

operation. To resume the programmed Sampling Method and Reporting

Method, send the port select code followed by <cr>.
