1. System Wiring Communications & Power

3. RS-485 Cable The standard wire used in RS-485 wiring is Belden 9842 – 24 AWG stranded (7x32) TC (tinned copper) conductors, polyethylene insulation, twisted pairs, overall Beldfoil® (100% coverage) + TC braid shield (90% coverage), 24 AWG stranded TC drain wire, PVC jacket

4. NEVER USE NETWORK CABLE FOR RS-485

6. 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)

13. Network Connection (Port 1) Port 2

15. 500FT! 150m! Normal close

19. FAIL SAFE

20. FAIL SECURE

24. AUS-1204

25. AUS-1210

32. 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.

33. What about…? What kind of wire should be used for communication and reader connections? What kind of Apollo power supply is suitable for an AIM-4SL with 4 AP-Prox readers and 4 Schlage M420 Mag locks? – Bonus question: How long will a 12Ah battery power this setup?
