Sometimes even the flexibility of RS- 485 isn’t enough: Problem: Star wiring patter is needed Solution: APM-10 star wiring adapter Problem: Runs of longer than 4000ft are required Solution: Extenders are available (including Apollo ENI-110s)
General Wiring Tips Optical isolators are a good choice for RS- 485 wiring that is connected to devices that are outdoor or could be subject to lighting strikes Be careful with wiring termination. Use terminal blocks and tip connectors where necessary. Don’t over-strip wires, make sure no bare wire is exposed anywhere to avoid crossovers that can affect communication or lead to power touching comm lines.
