Serial Communications<br />
The serial communication ports have been configured for 9600 baud rate, 8 bit data,<br />
1 stop bit and even parity. The user's system must be configured to suit this.<br />
Pr.62 Serial Communication Enable (Channel 1 - RS232, D=1)<br />
Channel 1 (RS232) 1 = Commissioning System<br />
2 = Polled data transfer<br />
Channel 2 (RS485) Is permanently enabled for polled data transfer<br />
Pr.63 Station Number (D=0)<br />
MULTIFLEX MANUAL 30<br />
EDITION 2 : NOV 2000<br />
SECTION 4<br />
For polled data transfer, the unit must have a station number assigned to it in the range 1-31,<br />
which must be unique to the unit.<br />
Echo Detection<br />
Pr.68 Echo Processing Algorithm (D=1)<br />
The system has two echo extraction techniques which will determine the "true" echo for the<br />
majority of applications where an echo is present.<br />
Enter 1 = For solids applications. This technique looks for the highest level<br />
within the transducer view.<br />
Enter 2 = For liquids. This technique positions a narrow 'window' around the<br />
target it is tracking to enable it to ignore a large amount of spurious<br />
noise.<br />
Pr.69 Check Search (D=1)<br />
Available only if Pr.68 is set to 2. It enables the instrument to look outside its window at<br />
intervals to check that there are no other relevant echos within the transducer's view.<br />
Enter 1 = Off<br />
2 = On<br />
Check search should be used where fill rates can sometimes be greater than that entered at<br />
Pr.6, or if the transducer is liable to be submerged.<br />
Pr.70 Echo Velocity (D=344.1 i.e. speed of sound in m/sec through air at 20°C)<br />
If operating through any other medium, enter the speed of sound through that medium in<br />
m/sec.
