About the use of RS485 repeaters?
Signals at both ends should be isolated and amplified, after all, bidirectional transmission. 4., I have tried 2 kinds of connection, the effect is similar, my network from the station more and interference, should be no problem. But habits make progress.
The repeater must, of course, be installed in the middle segment of the network, between your master station and slave station. 3. ends of the signal should be isolated from each other to enlarge, after all, two-way transmission.
The installation position depends on your needs.. It is better to install it near the physical length of 300 and 600 of your network. To achieve the best results.
