4210 Flow Meter
Section 2 Programming

You can enter the command line by connecting the interrogator
cable with the interrogator sense line shorted to ground. Then
send a series of ‘?’ (question marks) until the flow meter
transmits the unit’s banner and prompt. The number of question
marks necessary is a function of the baud rate auto detection. At
the prompt, enter DATA<CR> and the flow meter will respond
with the appropriate ASCII output string. You can send the
DATA command as often as you want. Type ‘Q’ to leave the
command response interface.
In addition to the port values, the data includes the flow meter’s
current time, the bottle number and time stamp of the three
most recent sample events, the previous day’s rainfall total (mid-
night to midnight), the current day’s rainfall total since mid-
night, and a rainfall bucket tips counter that rolls over every 255

Note: The output string for a given flow meter will
have values only for those parameters it is cur-
rently measuring. The order of the fields in this
table is subject to change. Additional data types
may be inserted anywhere in the list. Parsing
routines for this output string should search by
type identifier instead of depending on the posi-
tion in the string. If an active port has an error
flag set, the serial output will insert ERROR for
the value.
