Read commands are polled, which means the Model 3321 sends data in
response to a specific request from the computer
R
—Read Accumulator
This is a 3310 mode command. It dumps accumulator data taken using a G
command.
R b,e
where:
b = the beginning accumulator bin (0-1023).
e = the ending accumulator bin (0-1023). e must be greater than or equal
to b .
If b and e are not specified, the default values are b = 0 and e = 1023. Line
feeds are appended after all carriage returns.
Example Response
R0,100 Reads bins 0 to 100
R,100 Reads bins 0 to 100
R400 Reads bins 400 to 1023
R Reads bins 0 to 1023
RF
—Read Flags
RF returns a four-character hexadecimal value representing the state of
the Model 3321.
The values for the 10 flags are as follows:
0000 0000 0000 0001 Laser fault
0000 0000 0000 0010 Total Flow out of range
0000 0000 0000 0100 Sheath Flow out of range
0000 0000 0000 1000 Excessive sample concentration (alarm)
0000 0000 0001 0000 Accumulator clipped (i.e. > 65535)
0000 0000 0010 0000 Autocal failed
0000 0000 0100 0000 Internal temperature < 10°C
0000 0000 1000 0000 Internal temperature > 40°C
0000 0001 0000 0000 Detector voltage more than ±10% Vb
0000 0010 0000 0000 Reserved (unused)
