Using the 900 Series USB Converter
The USB Converter installs a Virtual Com Port (VCP) in the system and features full auto detection of baud
rate and communication standard (RS232 / RS485). The communication program should be configured to
the following parameters at all times:
115200 bps
1 stop bit
No parity
In order to communicate with the attached transducer the user simply has to choose the correct
communication port and use a serial communication program. We recommend Docklight
(http://www.docklight.de) by Flachmann und Heggelbacher. The program has a lot of features which makes
communicating with serial ports easy.
A list of the system communication ports can be found, in Windows 2000/XP, using the following guide:
Right click “My Computer” and choose “Properties”.
Go to “Hardware” and click on “Device Manager”.
Look under “Ports” and a list resembling the following appears:
On the picture above the attached USB Converter shows up as COM4. Note that the virtual comport may be
assigned to a different port than the one indicated above.
Loss of communication can occur when unplugging and reinserting the USB Converter (not the
transducer). If this happens closing and re-opening the communication port (in the communication
software) generally resolves the issue.
