Hach POLYMETRON 8810 - 5.4.3.3 Sample level detector; 5.4.3.4 Reagent level detector; 5.4.3.5 RS232 connection

5.4.3.3 Sample level detector
Refer also to Figure 6 on page 14 and Table 2 on page 15. The reactor is equipped with a sample
level detector. Wire the connection to J8 as follows:
J8 Terminal number Color
1 Brown
2 Green
3 Yellow
4 White
5.4.3.4 Reagent level detector
Refer also to Figure 6 on page 14 and Table 2 on page 15. Each reagent canister is equipped with a
level detector. For each reagent, wire the connections to J4, J5, J6 and J7 as follows:
J4, J5, J6 and J7 Terminal number Color
1 Not used
2 Not used
3 Brown
4 White
5.4.3.5 RS232 connection
Refer also to Figure 6 on page 14 and Table 4 on page 15. Wire the connection to J10 as follows:
J10 Terminal number DB9 Plug DB25 Plug
1 (TXD) RXD: 2 RXD: 2
2 (RXD TXD: 3 TXD: 3
3 (GND) COM: 5 COM: 7
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
