This chapter contains instructions for operating the serial interface of the
DMT152.
Connecting to the Serial Interface
The DMT152 can be connected to a PC using the RS-485 line on
Port II. You can use, for example, the USB serial interface cable (Vaisala
order code 219690). The cable also provides enough operating power for
transmitter configuration purposes from the USB port. For continuous
measurement, it is recommended to supply the transmitter with operating
power from another cable. See section Power Supply Requirements on
page 22.
If you have not used the DMT152 USB serial interface cable before,
install the driver that came with the cable. See section Installing the
Driver for the USB Cabl below for detailed instructions.
Installing the Driver for the USB Cable
Before taking the USB service cable into use, you must install the
provided USB driver on your PC. When installing the driver, you must
acknowledge any security prompts that may appear.
1.
Check that the USB service cable is not connected. Disconnect the
cable if you have already connected it.
2.
Insert the media that came with the cable, or download the latest
driver from
www.vaisala.com/software
3.
Execute the USB driver installation program (setup.exe), and
accept the installation defaults. The installation of the driver may
take several minutes.
4.
After the driver has been installed, connect the USB service cable
to a USB port on your PC. Windows will detect the new device,
and use the driver automatically.
