4. After the driver has been installed, connect the USB cable to a USB
port on your PC. Windows will detect the new device, and use the
driver automatically.
5. The installation has reserved a COM port for the cable. Verify the
port number, and the status of the cable, using the Vaisala USB
Instrument Finder program that has been installed in the
Windows Start menu.
Windows will recognize each individual cable as a different device, and
reserve a new COM port. Remember to use the correct port in the
settings of your terminal program. If you are using the Vaisala MI70
Link application, you do not need to check the COM port, as the MI70
Link detects the USB connection automatically.
There is no reason to uninstall the driver for normal use. However, if you
wish to remove the driver files and all Vaisala USB cable devices, you
can do so by uninstalling the entry for Vaisala USB Instrument Driver
from the Add or Remove Programs (Programs and Features in
Windows Vista) in the Windows Control Panel.
Using the Service Port
1. Unfasten the screws on the transmitter cover, and open the
transmitter.
2. Connect the desired cable (serial interface cable or USB cable) to
your PC and the service port connector on the transmitter. For the
location of the service port, refer to Figure 49 on page 74.
3. Open a terminal program and set the communication settings as
follows:
