Interface parameter:
Baud rate 2400 baud
Data bit 8
Stop bit 2
Parity None
Attention: By sending the command FC (hex) you will get the complete data, the
instrument lock auto-matically the keyboard. To release the keyboard you have
to send the command 0 (hex).
The datas would be sent in the following format.
Data Type = String
The length of the string depends on the instrument (a two-channel or one-chan-
