YSI 6000UPG - Manual (Page 132)

9-4
m - 6 character model number. This field always contains "EM6000" (Environmental Monitoring
System 6000
UPG ).
v - 3 character version number. This field holds the EMS6000 software version number ("100" for
version 1.00).
x - 0 to 13 characters identify active measurement parameters. These parameters are available
through "D0" to "D9" commands followed by an "M" command. Each parameter is coded as a
single character as follows.
'1'- Date
'2'- Time
'3'- Temperature
'4'- Specific conductance
'5'- Conductivity
'6'- Resistivity
'7'- Total dissolved solid (TDS)
'8'- Salinity
'9'- DO %
'A'- DO mg/L
'B'- ISE1
'C'- ISE2
'D'- Depth
'E'- Battery voltage
'H'- Turbidity

6000 UPG : a<values>[CR][LF]
<values>- 33 characters or less. This field holds one or more values resulting from a measurement
or verifying sequence. A value contains between 1 to 7 digits with an optional radix mark (period
'.' or comma ','). Each value must be preceded by its sign (either '+' or '-' ) since the sign is also used
to delimit multiple values. The time and date fields will not carry any separator. They always start
with a positive sign '+' followed by 6 digits (pre-filled with 0 if required). The order of date, month,
and year depends on the current date format which can be set in the System-setup menu (see
Section 4.5).
If the number of values returned by the "D0" command is less than the number specified in the
previous response to "M" or "V" commands, the rest of the data can be retrieved by using "D1" to
"D9" commands. The "D" commands are non-destructive. Thus, if the same "D" command is
issued multiple times before the next "M" or "V" command, it will return the same data. If the
response to the "D0" command is "a[CR][LF]" then either no "M" or "V" command was received
before the first "D" command or the "M" or "V" command was canceled.
Example: Assume that the date format is MM/DD/YY. The radix mark is set to period '.'. The
report output is set to report Date, Time, Temperature, Specific conductance, DO %, DO mg/L, pH
