Baud rate is set as described above; the other interface parameters are fixed as follows:
RS232 Character Set
Any ASCII code can be used. Bit 7 of ASCII codes is ignored, i.e. assumed to be low. No
distinction is made between upper and lower case characters in command mnemonics and they
may be freely mixed. The ASCII control codes between 00H and 31H are ignored, except for 0AH
(Line Feed, LF) which is used as a command terminator.
RS232 Remote Command Formats
The instrument's input buffer accepts a single command (or query) at a time, under interrupt, in a
manner transparent to other instrument operations. Commands and queries must be sent as
specified in the command list and must be terminated with the command terminator code 0AH
(Line Feed, LF). Note that parameters are separated from the command header by one space
(20H).
After a command has been sent the controller must wait at least 10ms from the command
terminator before the next command (or query) is started, to allow the instrument to clear the
input buffer.
Responses to queries are sent immediately. The controller must wait for the response to a query
before the next command or query is sent. The instrument responds to the controller after every
query as specified in the commands list. In every case a response is terminated by 0DH
(Carriage Return, CR) followed by 0AH (Line Feed, LF).
<WHITE SPACE>
except in command identifiers. e.g. '*I DN?' is not equivalent to '*IDN?'.
The high bit of all characters is ignored.
The commands are case insensitive.
