6700SR Refrigerated Sampler
100
Take Sample
The TAKE SAMPLE command is only valid if the sampler is WAIT-
ING TO SAMPLE. Format the command as follows:
BTL,2,SVO,100,CS,1039<CR>
• “
BTL,2
” instructs the sampler to place the sample in bottle 2.
• “
SVO,100
” instructs the sampler to take a 100 ml sample.
• “
CS,1039
” is the checksum value. The byte-by-byte sum of the
ASCII values in the string “
BTL,2,SVO,100,CS,
” is 1039.
• “
<CR>
” is a carriage return signifying the end of the command.
Set Time
The SET TIME command is only valid if the sampler is WAITING
TO SAMPLE. Format the command as follows:
TI,35523.50000,CS,988<CR>
• “
TI,35523.50000
” sets the time. The value “
35523.5000
” is
the number of days since 00:00:00 1-Jan-1900. This example
would set the sampler’s clock to 12:00:00 3-Apr-1997.
• “
CS,988
” is the checksum value. The byte-by-byte sum of the
ASCII values in the string “
TI,35523.50000,CS,
” is 988.
Command Driven Sampler Responses
The 6700SR Sampler’s response string is the same for each of the
three commands. A sample response string is shown below:
MO,6700,ID,2424741493,TI,35523.50000,STS,1,STI,
35523.41875,BTL,2,SVO,100,SOR,0,CS,xxxx<CR>
Note that the sampler’s response is a series of alphabetical and nu-
merical pairs. The alphabetical characters are headings that de-
scribe the following numerical value or code. A complete
description of each pair is listed below.
MO,6700,
is the model number of the sampler.
ID,2424741493,
is the sampler’s unique identification number.
TI,35523.50000,
is the sampler’s current time.
STS,1,
is the sampler’s current status. The possible states are:
1 = WAITING TO SAMPLE.
2 = IN SETUP MENU.
3 = SAMPLER DISABLED (pin F of external flow
meter connector.
4 = POWER FAILED (short duration after power is re-
stored).
5 = PUMP JAMMED (must be resolved before continu-
ing).
6 = DISTRIBUTOR JAMMED.
9 = SAMPLER OFF.
12 = SAMPLE IN PROGRESS.
20 = INVALID COMMAND. This will occur for any of
the following:
