4.1 Wiring ProtoNode RER to RS-485 Field Protocol (BACnet MS/TP

or Metasys N2)

Connect BAS BACnet MS/TP or Metasys N2 RS-485 port to the 3-pin RS-485 connector on

ProtoNode RER as shown below.

Figure 4-1: Connection from ProtoNode to RS-485 Field Protocol – BACnet MS/TP

NOTE

See Section 5 for information on connecting ProtoNode RER to

BACnet/IP network.

If the ProtoNode is the last device on the BACnet MS/TP or Metasys N2 trunk or if

using an RS232 to RS485 converter, then the End-Of-Line Terminator may need to

be enabled (See Figure 4-2). It is disabled by default.
