*The values for current and voltage are given as
numbers, scaled from 0 to 255, where 0 corresponds to
0 V and 255 to the full scale voltage (100 V) or current
(2.5 A).
When the Request is "G", the Answer will contain a
string of 11 characters with the following parameters:
Bytes
1-2 Pump cycles number (integer coded
in 2 bytes)
3 Speed threshold
4-7 Run up time in seconds
(long coded in 4 bytes)
8 Deat time
(0 = NO 1 = YES)
9 Controller OFF when R2 OFF
(0 = NO 1=YES)
10 Soft Start Mode
(0 = NO 1=YES)
11 CRC
When the configuration parameters have to be changed,
send a Request string with 9 characters of the following
type:
"H" + .... data .... + CRC
