Instruction
|
|---|---|
|
1
|
Link all outputs labeled + (Tx+, Rx+) to the network wire labeled: L+.
|
|
2
|
Link all outputs labeled - (Tx-, Rx-) to the network wire labeled: L-
|
|
3
|
Adapt the network's impedance using two adaptation nodes (Zc) located on the two end stations of the network.
|
|
4
|
For of distributed polarization of the network, link the L+ 5 V wire to the L- 0 V wire via two polarization resistors (Pr = 4,7 KΩ). Do this for each station. This polarization will keep the network stable while not in use.
