Gpib Remote Command Formats; Remote Commands - Ametek Sorensen XEL Serie Mode D'emploi

RS232/USB Remote Command Format
RS232 input to the instrument is buffered in a 256 byte input queue which is filled, under interrupt,
in a manner transparent to all other instrument operations. The instrument will send XOFF when
approximately 200 characters are in the queue. XON will be sent when approximately 100 free
spaces become available in the queue after XOFF was sent. This queue contains raw (un-
parsed) data which is taken, by the parser, as required. Commands (and queries) are executed in
order and the parser will not start a new command until any previous command or query is
complete. RS232 responses to commands or queries are sent immediately; there is no output
queue.
USB input conforms with USB 2.0 Full Speed.
Commands must be sent as specified in the commands list and must be terminated with the
command terminator code 0AH (Line Feed, LF). Commands may be sent in groups with
individual commands separated from each other by the code 3BH (;). The group must be
terminated with command terminator 0AH (Line Feed, LF).
Responses from the instrument to the controller are sent as specified in the commands list. Each
response is terminated by a
CR) followed by 0AH (Line Feed, LF).

GPIB Remote Command Formats

GPIB input to the instrument is buffered in a 256 byte input queue which is filled, under interrupt,
in a manner transparent to all other instrument operations. The queue contains raw (un-parsed)
data which is taken, by the parser, as required. Commands (and queries) are executed in order
and the parser will not start a new command until any previous command or query is complete.
There is no output queue which means that the response formatter will wait, indefinitely if
necessary, until the instrument is addressed to talk and the complete response message has
been sent, before the parser is allowed to start the next command in the input queue.
Commands are sent as
