4 INTERFACING PROTONODE TO DEVICES
4.1 Device Connections to ProtoNode
The ProtoNode has a 3-pin Phoenix connector for connecting RS-485 devices on the R1 port.
NOTE: Use standard grounding principles for RS-485 GND.
4.1.1 Lochinvar Low Voltage Modbus RTU Wiring to the ProtoNode (Armor,
SYNC/Armor X2, Knight/Knight XL, Crest, Copper-Fin II and FTXL)
•On the Lochinvar’s Modbus terminal strip, connect Pin A (RS-485+) to B+ (RS-485+) on the
ProtoNode’s R1 port 3-pin Phoenix connector.
•On the Lochinvar’s Modbus terminal strip, connect Pin B (RS-485-) to A- (RS-485-) on the
ProtoNode’s R1 3-pin Phoenix connector.
•The Shield Pin on the terminal strip (which is Ground) does not need to be grounded to the
ProtoNode.
4.2 Wiring Field Port to RS-485 Serial Network
•Connect the RS-485 network wires to the 3-pin RS-485 connector on the R2 port. (Figure 7)
oUse standard grounding principles for RS-485 GND
•See Section 5 for information on connecting to the Ethernet network.

4.3 Bias Resistors
To enable Bias Resistors, move both the BIAS- and BIAS+ dip switches to the right as shown in
Figure 8.
The ProtoNode bias resistors are used to keep the RS-485 bus to a known state, when there is no
transmission on the line (bus is idling), to help prevent false bits of data from being detected. The bias
resistors typically pull one line high and the other low - far away from the decision point of the logic.
The bias resistor is 510 ohms which is in line with the BACnet spec. It should only be enabled at one
point on the bus (for example, on the field port were there are very weak bias resistors of 100k). Since
there are no jumpers, many gateways can be put on the network without running into the bias resistor
limit which is < 500 ohms.
NOTE: See www.ni.com/support/serial/resinfo.htm for additional pictures and notes.
NOTE: The R1 and R2 DIP Switches apply settings to the respective serial port.
NOTE: If the gateway is already powered on, DIP switch settings will not take effect unless the
unit is power cycled.

4.4 Termination Resistor
If the ProtoNode is the last device on the serial trunk, then the End-Of-Line Termination Switch needs to
be enabled. To enable the Termination Resistor, move the TERM dip switch to the right in the
orientation shown in Figure 9.
Termination resistor is also used to reduce noise. It pulls the two lines of an idle bus together. However,
the resistor would override the effect of any bias resistors if connected.
NOTE: The R1 and R2 DIP Switches apply settings to the respective serial port.
NOTE: If the gateway is already powered on, DIP switch settings will not take effect unless the
unit is power cycled.
