Read out of the operating hours counter
The operating hours counter of
rain[e]H3
can be read out with following command:
<STX>COM:27<CR><LF>
Answer:
<STX>X<CR><LF> with X = operating hours
Start Measurement Intensity <STX>a<CR><LF>
The command <STX>a<CR><LF> can be used to ask the sensor for the average, maximum and minimum intensity
over a selected time frame. This time frame has to be selected in the “ Setup ” of the rain[e]H3 Commander.
Syntax:
Command Answer
<STX>a<CR><LF> int
avr
;int
max
;int
mini
;<CR><LF>
<STX> – Start of command int
avr
– Average intensity in mm/min
a – Command ‘Measurement Intensity’ int
max
– Maximum intensity in mm/min
<CR><LF> – End of command int
mini
– Minimum intensity in mm/min
<CR><LF> – End of answer
Example:
Command Answer
<STX>a<CR><LF> 0.059;0.073;0.031;<CR><LF>
10.2.3 Talker Protocol
The Talker protocol is the third available mode of the RS485 interface. It sends an ASCII string in a defined
interval. The interval can be adjusted between 10...60 s using the rain[e]H3 Commander.
The baud rate is 19200 Bd and has the byte frame format 8N1:
8 data bits
no parity bit (no parity)
1 stop bit

is a decimal representation of a binary number. In binary representation the positions
correspond to the following status messages:
