NETWORKS
4.1 Wiring the ProtoNode RER to RS-485 Field Protocol
The Field Protocol can be connected to the 3-pin connector on the ProtoNode RER as shown:
Figure 9. Connection from ProtoNode to RS-485 Field Protocol –BACnet MS/TP or Metasys N2
NOTE: For information on connecting the ProtoNode RER to a BACnet/IP network, see Section 5.
4.2 Wiring the ProtoNode LER Field Port to a LonWorks network
• Connect the ProtoNode to the field network with the LonWorks terminal using a twisted pair non-
shielded cable. LonWorks has no polarity
4.3 Power-Up the ProtoNode RER or LER
Apply power to the device. Ensure that the power supply used complies with the specifications provided in
Appendix B. Ensure that the cable is grounded using the “Frame-GND” terminal.
The ProtoNode features a multi-mode power input and accepts either 9-30 VDC or 12-24 VAC.
