• Calibration Alarm timeout for ISE (2 chars) - if ISE
available when x=1 (HI 3221) or when x=2 (HI 3222)
• SETUP information (2 chars): 8 bit hexadecimal encoding.
• 0x01 - beep ON (else OFF)
• 0x04 - degrees Celsius (else degrees Fahrenheit)
• 0x08 - Offset calibration (else Point calibration)
• The number of custom buffers (1 char) when x=1
• The custom buffer values, with sign and decimal point,
for each defined custom buffer (7 chars) when x=1
• The ID of the ISE electrode (2 chars) - if ISE available
when x=1 (HI 3221) or when x=2 (HI 3222)
• The molar weight of the selected ION, with sign and
decimal point (9 ASCII characters) when x=1 (HI 3221)
or when x=2 (HI 3222)
• The electrode slope (6 ASCII chars)
• The ion charge (2 chars)
• The ISE unit (2 chars)
• The short name of the selected language (3 chars)
NSLxy Requests the number of logged samples (4 chars).
The command parameter (2 chars):
• x=1 request for channel 1
• x=2 request for channel 2
• y=P request for pH range when x=1
• y=M request for mV and Rel mV ranges
• y=I request for ISE range when x=1 (HI 3221) or
when x=2 (HI 3222)
LLSxy Requests the number of lots (information about lots) on the specified
channel and range (x - channelnumber; y - range number)
• xy = 11 - channel 1; range pH;
• xy = 13 - channel 1; range mV;
• xy = 22 - channel 2; range ISE;
• xy = 23 - channel 2; range mV;
The answer string contains:
• number of lots (3 chars)
• ID lot (3 chars)
• date (6 chars)
• time (6 chars)
