9100S Dry-Well Calibrator
Interface Commands
32
The serial port can be used to transmit measurements to a computer or printer or to
change settings of the instrument from a computer. A full list of commands follows in
Section .
Commands sent to the instrument must end with an EOS character which is a carriage
return (CR, ASCII 13) or linefeed character (LF, ASCII 10). Commands can be
sent with upper or lower case letters. Data returned from the instrument ends with a
carriage return. If the linefeed setting is on, a linefeed character is also sent afer the
carriage return.
7.2 Interface Commands
The various commands for accessing the calibrator functions via the digital interface
are listed in this section (see Table ). These commands are used with the RS-232
serial interface. The commands are terminated with a carriage-return character (CR,
ASCII 13). The interface makes no distinction between upper and lower case letters,
hence either may be used. Commands may be abbreviated to the minimum number of
letters which determines a unique command. A command may be used to either set a
parameter or display a parameter depending on whether or not a value is sent with the
command following a “=” character. For example “s” returns the current set-point and
“s=150.0” sets the set-point to 150.0 degrees.
In the following list of commands, characters or data within brackets, “[” and “]”, are
optional for the command. A slash, “/”, denotes alternate characters or data. Numeric
data, denoted by “n”, may be entered in decimal or exponential notation. Characters
are shown in lower case although upper case may be used. Spaces may be added
within command strings and will simply be ignored. Backspace (BS, ASCII 8) may be
used to erase the previous character. A terminating (CR, ASCII 13) is implied with all
commands.
