threaded connector. See list of available cables in section Options and
Accessories on page 68.
The probe does not echo typed characters back to the terminal screen. To
see the commands you type, you need to enable the
"local echo" setting in your terminal program.
A new command cannot be received while the probe is sending data out.
Wait until the instrument has completed its response before entering the
next command.

You can change the serial settings and operate in RUN, STOP and POLL
modes:
- After power-up the probe (in STOP mode) outputs the software
version and the command prompt.
- In RUN mode, a measurement output starts immediately after power-
up.
- In POLL mode, the probe does not output anything after power-up. It
must be accessed with an addressed command.
For a description of the modes and the SMODE command that is used to
change the mode, see section Set Serial Interface Mode on page 40.
