Channel Order (Canada)
Only a single continuous line of data is returned.
:HG 5 #15 18.34 18.76 18.97
19.43 :TA 5 #15 22.78 22.45
22.15 22.02 :VB 5 #15 12.45
12.44 12.45 12.45
Each Task begins with a colon (:)
followed by the SHEF header, the
minutes since the last scan, the scan
rate in minutes, followed by the
measured values.
If the Canada layout is chosen, Channel Order is forced, though a different style is used.
Append Battery Scan
This option allows one battery reading to be appended to the data being transmitted. If the
WaterLOG H-2221 GOES Radio is being used, the lowest battery reading of either a current
battery measurement or the battery reading during the previous transmission (of the
loaded battery) will be used. Otherwise, the battery value is retrieved just prior to transmission.
Normal applications transmit 15 minute data yet battery values are generally not required
that often. Fifteen minute battery readings also take up transmit time that could be used for
other data values. Selecting ‘Yes’ to this option allows the user to still get a battery value for
each transmission, while shortening the transmit time and allowing other data values to be
transmitted instead.
Redundant Data Sets
Defines the number of extra data sets to send with each transmission. A data set is defined
as the data collected between transmissions. Setting this option to 0 would cause the next
transmission to contain only data collected since the last transmission. The default value is 1,
indicating that one set of extra or redundant data will be sent along with the new data. The
new data would be the data collected since the last transmission and the extra data set(s)
would be the data collected between the older transmissions in logical order. Sending
redundant data is a common practice with the GOES system, and allows the same data to be
transmitted more than once, protecting against lost transmissions.
Center Data
Defines whether the transmitted data is centered within the transmission window. The default
is to not center the data, which means the transmission will start at the beginning of
the window. If set to center the data in the window, the System 5000
™
will calculate
approximately how long it would take to transmit the selected data and delay the start of the
transmission to center the data in the middle of the window. If enabled, the centering process
is done automatically, and the user should not add any time to the Transmit Time option in an
attempt to center the data.
