7 PROPRIETARY RS232 MODE
In proprietary RS232 mode, the instrument sends automatically the acquired measurements at
regular intervals. The interval is factory-set to 1 second and is configurable from 1 to 3600
seconds. To change the interval, you should enter in configuration mode and send the com-
mand CU2Rnnnn, where nnnn indicates the interval value in seconds (see chapter 6 “CON-
FIGURATION” for details regarding the setting of operation parameters).
To use this mode, you must connect to a RS232 serial port. Communication parameters should
be set in your PC as follows:
 Baud rate: 9600 to 57600 (same as the setting in the instrument)
 Data bits: 8
 Parity: None
 Stop bits: 2
The instrument sends measurements in the following format:
<M1><M2>….<Mn><CR><LF>
with <M1><M2>….<Mn> = values of the first, second,…., nth measurement
<CR> = ASCII character Carriage Return
<LF> = ASCII character Line Feed
Fields <M1><M2>….<Mn> consist of 8 characters each. Measurement values are justified
right; spaces can be added to the left margin of the values to obtain the 8 character length re-
quested by the fields.
The sequence of the measurement values <M1><M2>….<Mn> is configurable (see chapter 6
“CONFIGURATION”).

XAMPLE
Supposing that the instrument measures the following values (the measuring unit is not con-
sidered, being not output by the instrument): M1=2.23, M2=-28.34, M3=0.34, M4=28.30,
M5=359.3, M6=-1.3, the data string sent by the instrument takes the form:
2.23 -28.34 0.34 28.30 359.3 -1.3<CR><LF>
