NOTE

The Vaisala USB cable is not designed for permanent installation.

When using the USB cable, no separate power unit is needed. The probe

is powered through the USB port.

For permanent interfacing to a host system, use a shielded cable with a

threaded connector. See list of available cables in section Options and

Accessories on page 62.

You can change the serial settings and operate in RUN, STOP and POLL

modes. 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.
