i2C Connecting sensors and devices to the i2C bus
Devices and sensors are connected via a 4-wire circuit. The color of the loop wires is identical for all sensors and
devices manufactured by
NetPing east Co Ltd
.
Only sensors and devices of own design are supported, these include:
— up to 8 pc.;
A sensor is packaged with an inseparable cable, with connectors on the ends. A cable length can be increased with
the help of
sensor, which are sequentially plugged one into another. Otherwise, it can
be done independently with the help of any wire with a minimum cross section of 0,4 mm
2
. Maximum allowable
length of a flat cable is 10 m from each sensor to a device (star topology).
All sensors and devices are connected in parallel to each other in the same terminal blocks according to the
following scheme:
