USE
Run a computer program allowing you to communicate with the VELBUS system. Download this program, the tutorial
or all needed information to write a custom program through our
http://www.velbus.be/consumers/downloads/
Connect the module to the VELBUS system and the computer (see Connection).
First install the driver when first connecting the module to a computer through a USB port. The computer’s operating
system will detect the new hardware and will ask to localise and to install the driver (.inf file) (c:\Program
Files\Velleman\VelbusLink\Driver). Once the driver correctly installed, you can use the Velbuslink program.
When powering the module, a “Bus active” and “Reception ready” message will be sent to the computer.
All messages appearing on the VELBUS system will also be sent serially to the computer.
Valid commands generated by the computer will be sent to the module via the serial or USB port.
These commands are placed on the VELBUS system through the interface module.
When an excessive amount of commands has been sent in one time, the reception buffer will be filled. This will be
reported to the computer. The computer program must interrupt the forwarding and wait for a “Reception ready”
message to be able to offer new commands.
If the commands can not be placed correctly on the VELBUS, a bus error will occur and will be forwarded to the
computer. The interface module will auto-restart after 25 seconds and erase the reception buffer.
