Since all devices are connected by a common bus, make sure the quality of the connection of all nodes of the line: | |||

We recommend the use of whip tips for a swage [http://www.chipdip.ru/catalog-show/tips/ pin tips for crimping]. This makes it easy to connect and disconnect devices without losing the operation of other devices on the bus. When used with the mounting lugs of the NSVI it is necessary that the diameter of the insulated cuff does not exceed the dimensions of the terminals of the devices. | |||
Wire A on all devices is connected to the terminal strip marked A, wire B - always to B. On the wire Board next to the terminals A and B are GND and Vout terminals - you can immediately connect the power lines (first check the power requirements of your devices!). | |||
Life hack: since there are stretching lines inside the Wiren Board controller, after connecting it to the bus line A voltage will be greater than b by about 0.5 V. Therefore, connecting peripherals you can easily determine the bus line by the voltmeter. But, of course, color coding of conductors is more preferable. | |||

# | #The differential line gives good noise immunity. The length of the line is up to 1200 meters. | ||
# | #When laying the bus, you need to follow [http://www.gaw.ru/html.cgi/txt/interface/rs485/app.htm certain rules], but for transmission in one apartment, any cable will fit and even branches are possible. |
