Using Serial Data Commands C-17
Example Response
RF 00AC
00AC can be converted to binary: 0000 0000 1010 1100
This indicates that:
Internal temperature is greater than 40°C
Autocal failed
Excessive sample concentration
Sheath flow out of range
RI—Read Input From Pins 1, 2, 3 and 7, 8 of the
I/O Connector
Pins 1, 2, and 3 are digital inputs and are reported as a binary number 000
to 111, where a 1 indicates 5 VDC level on the pin. (Digital ground pins for
the inputs are 9 and 10.) Pins 7 and 8 are analog inputs referenced to pin
15 analog ground. The analog values are reported as a decimal number
from 0.0 to 5.000 VDC. All readings are instantaneous.
Example Response
RI 100,2.43,1.93
Pin 1 has logic level high (5 VDC). Pins 2 and 3 are logic level low (0
VDC). Pin 7 is 2.43 VDC. Pin 8 is 1.93 VDC.
RL—Read Laser Power
Reads the current laser power output in percentage (%) of maximum
milliwatts and current in milliamps (ma)
Example Response
RL 75.0, 65.3
Indicates the laser power output is 75 percent of maximum output and
current is 65.3 ma.
RO—Read Accumulated On Time
Reads the accumulated on-time of the instrument (in hours). The time is
updated once an hour and stored in EEROM.
Example Response
RO 72
Indicates the Model 3321 has been on for approximately 72 hours.
