The character structure conforms to the ISO 1177 standard. It is compatible with the 'RS-232' interfaces of
personal computers.
The character parameters are configuration selectable:
speed 1200 to 9600 bits/s
parity odd, even or none
stop bits 1 or 2
flow control hardware, XON / XOFF or none.
The set of measurement results is output in a fixed-length record. The record consists of variable-length
numeric fields at fixed locations in the record. The gaps are filled with ASCII spaces (code 20 hex).
The record format is (program version 4.0 and newer):
Column Field Format Value
1 TEST float, 1 decimal raw refraction value
16 CONC% float, selected decimals concentration value
31 temp C float, 1 decimal temperature, degrees centigrade
46 RI 25 C float, 4 decimals standard RI at 25 C
61 phase 1 digit operation phase code
63 error integer error code
66 divert integer divert control status code
68 checksum integer
76 terminator CR and LF
