YSI Level Scout - Manual (Page 28)

The format for the broadcast messages is ASCII characters (7 data, even parity, 1 stop bit) at the current baud rate, with the following
formatted data:
‘accctt+yyyy/mm/dd_hh:mm:ss.ss,[ v u,]<cr><lf>’
Where ‘a’ is the transducer address, ‘ccc’ is the broadcast ID code (table 1), and ‘tt’ is the active test profile number. Next follows a
plus sign (+) and time stamp (yyyy/mm/dd_hh:mm:ss.ss) followed by the formatted decimal datum for each measurement actually
scanned per the current test profile. Each datum value (v) is followed by a unit name (u).
A space separates each v and u, and a comma (,) follows each u. A carriage return, line feed combination ends the string.

communications (Site) network. Use of multiple transducers may result in data transmission
collisions resulting in a failure of correct packets to be transmitted.
