B.1 Communication parameters
B.1.1 Default communication parameters
The default communication parameters are:
• Baud rate : 19200 bps
• Parity : none
• Data bits : 8
• Stop bits : 1
• Flow control : none
When the server receives a serial break signal, it will switch to default communication parameters. After 5 seconds of inactivity of the
HOST, it will switch back to the configured communication parameters. This feature ensures the HOST can always gain access to the
instrument.
B.1.2 Miscellaneous
Command, request and response lines are terminated by a linefeed <LF>. Carriage returns <CR> are discarded in commands and
requests.
B.2 Client server protocol
The instrument provides the information and will send a response on every command from the HOST. Every request from the
HOST is acknowledged by 0, 1 or more responses and a prompt. See examples 1 to 3. The instruments transmit a status message
periodically. A status message should not be acknowledged by the HOST (see example 4).
