Service Cable Connection
The service cable connection with fixed serial port settings is
recommended for checking/changing the device settings. When making
the changes, use the Vaisala Configuration Tool or a standard PC
terminal program.
The service cable is included in the Vaisala Configuration Tool kit, see
Table 20 on page 127 . For a picture of the service cable, see Figure 6 on
page 19 .
When you connect the service cable between the service connector and
PC serial port, the serial port settings are forced automatically to RS-
232 / 19200, 8, N, 1. At the same time, the normal serial port at M12 and
at screw terminals is disabled. The battery (9 V) attached to a cable
provides the power to WXT510. Alternatively the normal power
connection through M12 or screw terminals can be used (simultaneous
use with 9 V battery is allowed).
1. Make a connection between the serial port of your PC and the
service port connector on the bottom plate of the transmitter (see
Figure 4 on page 18 ) by using the service cable.
2. Power-up WXT510 with a 9 V battery attached to the service cable
or by using the screw terminals/M12 connector.
3. Open the Vaisala Configuration Tool/terminal program. Select the
following default communication settings: 19200, 8, N, 1.
4. Make the desired changes. When working with a terminal program,
see section
Communication Setting Commands on page 48 .
NOTE The RS-485 and RS-422 interfaces cannot be directly accessed with a
standard PC terminal. They require a suitable converter.
NOTE RS-232 and SDI-12 can be accessed with a standard PC terminal,
presuming that, for SDI-12, the Data in/out lines have not been
combined inside WXT510.
