FEATURES ◊ ◊ ◊ ◊ ◊ ◊ ◊ ◊ ◊ VELBUS system control through a computer VELBUS message processing on the computer Galvanic separation between the computer and the VELBUS system LED indication for the USB power supply Required mains voltage: 12 to 18 VDC Power consumption: 15 mA Power consumption USB port: 35 mA Standard DIN rail enclosure (2 modules) Dimensions (L x W x H): 90 x 36 x 58 mm VELBUS: ◊ ◊ ◊ ◊ ◊ ◊ ◊ ◊ 2-wire communication for the VELBUS data and 2 wires for power. Data transfer: 16.
CONNECTION RS232 connection Indication LED USB power USB connection RS232 connection 12V power output VELBUS 12V power input VELBUS connection Connection of the modules is preferably done using twisted-pair cables (EIB 2x2x0.8mm2, UTP 8x0.51mm - CAT5 or similar). Use a twisted pair cable with 0.5mm² gauge or more when connecting more than 10 modules or with long connections (more than 50m). Connect the 12 to 18VDC (mind the polarity) to the module. Connect the bus (mind the polarity) with the module.
Remark: You can also install the serial connection elsewhere (e.g. on the side of the fuse box). Use a 9-pole female Sub-D connector (Velleman ref. CC005). CONNECTION WITH THE COMPUTER Remove the cover from the module. Connection through serial port Connect the module to the COM port of the computer using a serial cable (Velleman ref. CW014).
Connection through USB port Connect the module to a USB port of the computer. Use one of the following Velleman USB cables: CW076, CW077, CW078, CW090A, CW090B or CW090C. Remark: The serial and USB connections are galvanically separated from the VELBUS and the 12V power cable through an optical link. Only use one of the possible connection methods: through the serial or through the USB port. Never use both connection methods simultaneously.
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 (.
