pressing "SET" and release to enter the secondary menu. Press "SET" repeat-
edly until the display reaches "PrObE". This is the menu selection. Press "UP"
repeatedly until the IEEE-488 interface menu is indicated with "IEEE". Press
"SET" to enter the IEEE-488 parameter menu. The IEEE-488 menu contains
the IEEE-488 address parameter.
The IEEE-488 address is prompted with "AddrESS". Press "SET" to program
the address. The default address is 22. Change the device address of the bath if
necessary to match the address used by the communication equipment by
pressing "UP" or "DOWN" and then "SET".

IEEE-488 Operation

Commands may now be sent via the IEEE-488 interface to read or set the tem-
perature or access other controller functions. All commands are ASCII charac-
ter strings and are terminated with a carriage-return (CR, ASCII 13). Interface
commands are listed below.

Interface Commands

The various commands for accessing the bath controller functions via the digi-
tal interfaces are listed in this section (see Table 5). These commands are used
with both the RS-232 serial interface and the IEEE-488 GPIB interface. In ei-
ther case the commands are terminated with a carriage-return character. The in-
terface 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"<CR> returns the
current set-point and "s=50.00"<CR> sets the set-point to 50.00 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 termi-
nating CR is implied with all commands.
