Figure 3 - 1-wire preferred topology
The PA Pro is connected at one end of the 1-wire bus and each sensor is connected to the bus with
branches or “stubs” where each stub is less than 3m. The
PA Pro can handle a total of 16 sensors
and a total “weight” of 65 m. Th
e weight is the length of all 0.5m per 0.5m per
split.
Weight = total cable 0.5* 0.5*split
Example: 3 sensors on 2 meter stubs that is located 5 meters from the PA Pro with 1 split has a total
weight of 0.5*3+(2*3+5)+0.5*1=14.
Do not run signal wires in parallel with power cables.
Check section 7 for configuration of 1-wire sensors.
