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
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
