Appendix: Advanced Connections
The Base Station connects to a computer running FMS using a USB Interface.
The USB specifications requires that the total cable length is no more than
16.5' (5 m).
Note: The advanced connection solutions described below include products that are not
available for purchase through Davis Instruments.
USB Extender
A USB Extender is an inexpensive device which uses a small block at each
end of a Category 5 cable to amplify and shape USB signals. It receives the
needed power for the small blocks at both ends of the cable from the USB
port, and requires no external power. Since the extra cable length is invisible
to the computer, there are no drivers, or any other software to install on the
computer. This solution allows the Base Station to be installed up to 150'
(45 m) from the computer.
We have tested the base station with the VAD-1120, and any similar product
should work as well.
A Google search for the term “USB Extender” should give you multiple
product choices.
USB Device Server
The USB device server is a small box which provides a USB connection for
the Base Station and connects to the computer running FMS through your
company intranet. The USB server carries the USB data as TCP/IP data and
transfers it via the company intranet to the computer running FMS. There are
no practical distance limits since it used the company intranet. The USB
Server comes with a wall lump power supply, and requires connection to the
power line.
