ISTRUZIONI ORIGINALI
• "D" = Low Speed OFF
• "E" = Request for operational parameters
• "F" = Pump times zeroing
• "G" = Parameters reading
• "H" = Parameters writing
• "I"
= Request for operating status
• "J" = Request for numerical reading
• "K" = Request for counters reading.
CRC corresponds to the sum (with inverted sign)
of all the preceding bytes.
e.g.,
the
START
command
code = 41; inverted it will be: FF + 1 - 41 = BF.

When the Request is "A, "B", "C", "D", "F", the
Turbo-V 301 controller will Answer the ACK or
NACK.
When the Request is "E, the Answer will contain
the complete set of the following parameters:

*The values for current and voltage are given as
numbers, scaled from 0 to 255, where 0 corre-
sponds to 0 V and 255 to the full scale voltage
(130 V) or current (2.5 A).
When the Request is "G", the Answer will con-
tain a string of 11 characters with the following pa-
rameters:
BYTES
1-2
Pump cycles number
(integer coded in 2 bytes)
