The 8810 configuration is:
• Speed: 9600 baud
• Data: 8 bits
• Stop bit: 2
• Parity: none
On startup the analyzer sends the name and software version:
• ANALYZER 8810 : 00 : 00 : 00 :
• ISE X.XX : 00 : 00 : 00 :
In measurement mode, the analyzer sends the following data:
• Measure HH : MM : SS
• M1 XXXXEXX XX.X°C XXX
Where:
• MX = M1 for channel 1 or M2 for channel 2
• XXXXEXX = concentration measurement value
• XX.X°C = temperature
• XXX = value of the potential
Where appropriate, the analyzer also sends the following messages with a time stamp
(HH : MM : SS):
