IEEE-488 interface menu is indicated with "IEEE". Press "SET" to enter the
IEEE-488 parameter menu.

IEEE-488 Address

The IEEE-488 address is indicated 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" . Press "SET" to save the new setting or "EXIT" to
abort and skip to the next parameter.

Transmission Termination

The IEEE-488 transmission termination is indicated with "EOS". Press "SET"
to access the termination character. The present setting is displayed. Press "UP"
or "DOWN" to change the setting. Press "SET" to save the new setting or
"EXIT" to abort and skip to the next parameter.

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 starting on page 62). These
commands are used with both the RS-232 serial interface and the IEEE-488
GPIB interface. In either case the commands are terminated with a carriage-re-
turn character. 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 an "s" <cr> returns the current set-point and an "s=50.00" <cr> sets
the set-point to 50.00 degrees.
In the list of commands, characters or data within brackets, "[" and "]", are op-
tional for the command. A slash, "/", denotes alternate characters or data. Nu-
meric 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 is
implied with all commands.
