Although the USB communication device can be installed on any USB port connected to your
computer, using a non-powered USB hub or extension cable increases the chance for interruptions
between the USB communication device and your computer. Where obstructions are an issue, a good
quality 6ft USB extension cable can be used if it is directly connected to either a powered hub or a port on
the computer itself.
For best performance, we recommend that the USB device be connected to a USB port directly on your
computer. An externally powered USB hub can be used, but avoid using a self powered USB hub or
extension cable longer than 6ft.These USB extension devices cannot generate sufficient power to
maintain ongoing communication.
SYNCHRONIZING
WHAT IS SYNCHRONIZING?
Synchronizing is the process of telling the weather station and the Heavy Weather software how to talk to each
other. The weather station and the USB communication device first go through an identification or introduction
process. During this process, the weather station will send out a signal identifying itself with a special identification
code. The USB device also sends out a signal with an identification code. When the two devices locate each other,
they store the ID code of the other device, so they can ‘lock onto’ each other. This allows the weather station and
the software (through the USB device) to connect and communicate again, should they ever lose connection with
each other. It also means that once they are locked onto each other, they won’t interfere with another weather
station that may be nearby (this keeps the neighbors happy).
SYNCHRONIZATION CHECKLIST
Before we begin to synchronize the Heavy Weather Pro software with your LaCrosse Technology weather station,
let’s make sure that all of the components are ready to go.
1. The weather station is set up and receiving data.
IF YOU HAVE NOT YET INSTALLED AND CONFIGURED THE WEATHER STATION, please refer to the
installation and setup documentation for your weather station before continuing with the
synchronization.
2. The USB communication device is installed properly.
IF YOU HAVE NOT YET INSTALLED THE USB COMMUNICATION DEVICE, please refer to the section on
installing the USB communication device and do that before continuing.
