- - - - X X X X
0 = STOP
1 = WAITING INTERLOCK
2 = STARTING
3 = NORMAL OPERATION
4, 5 = HIGH LOAD
6 = FAILURE
7 = APPROACHING LOW SPEED
2÷5 Cycle Time

*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 (75 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 Soft Start mode
(0 = NO 1=YES)
10 Water cooling
(0 = NO 1=YES)
11 CRC
When the configuration parameters have to be changed,
send a Request string a string with 9 characters of the
following type:
"H" + .... data .... + CRC
