Answer = after a request from the host, the
Turbo-V 250 PCB controller will answer in one of the
following ways:
•
ACK
•
NACK
•
Message
When the Request is "A, "B", "C", "D", "F", the Turbo-V
250 PCB controller will Answer the ACK or NACK.

*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)

When the configuration parameters have to be changed,
send a Request string with the letter "H" and a series of
