S - Send Extended
This command sends the test address followed by the user entered text in the “Edit Extended
Cmd” command option followed by “!”. If an error occurs, the H-5223 responds with
“Communication Timed Out.” Refer to the sensor manufacturer for proper response to the
corresponding Extended Command.
E - Edit Extended
This options is used to enter a non standard SDI-12 extended command to be sent to the
sensor. The address MUST NOT be included in this text and the command terminator “!” is
optional as both are added automatically when the extended command is sent.
P - +12Vx Mode
The +12 volt excitation can be set to be on at all times or only on for the scan. The default is
on at all times.
3.6 D - Data Options
The options under this menu allow the user to see the status of the data memory including how
full is the data memory and free bytes. Also the options to transmit and erase data. The
following shows what the “Data Options” screen looks like:
--- Data Options ---
Data Status: OK
Bytes Free: 2159520 (0.0% Full)
File Count: 0 of 8
T - Transmit Data
N - Transmit New Data
R - Reset New Data Pointer
F - Erase Last File
E - Erase All Data
Enter Option >
Data Status: This is a status indication regarding health of the data memory. Messages
may include ‘Erase Error’ ‘Write Error’, and ‘Warning over 50% full’, indicating it may be
good to save and then erase some data. If the system has filled the memory and it has started
to wrap around, the message “OK (Wrapped)” will be displayed.
Bytes Free: This is a status indication of how full the data memory is at the present time.
Data is stored in a compressed mode so each data value only takes 4 bytes.
There are 2159520 actual bytes available for data storage and each data value takes 4 bytes.
Therefore, the total number of data values able to be stored is 2159520 / 4 = 539880.
To calculate how long it will take to fill the data memory use the following equation.
(Bytes Free * Scan Rate in minutes) / (5760 * log columns defined) = days left to fill
memory.
