4.3.2 Set Node-ID for Any Device Attached to the MB485ETH-CG
•Set Node-ID for the device attached to MB485ETH-CG. The Node-ID needs to be uniquely
assigned between 1 and 255.
•Document the Node-ID that is assigned. The Node-ID assigned is used for deriving the Device
Instance for BACnet/IP and BACnet MS/TP.(Section 10.5)
NOTE: The Modbus TCP/IP field protocol Node-IDs are automatically set to be the same value as
the Node-ID of the device.
4.3.3 Set IP Address for Any Ethernet Device Connected to the MB485ETH-CG
•Ensure the device is set to Modbus TCP/IP to communicate with the MB485ETH-CG.
•The device needs to be on the same IP subnet as the MB485ETH-CG and the configuration PC.
•Record the following device information to start the setup:
oIP Address
oIP port
oTCP_ID
NOTE: This information is required for Section 10.3.
4.4 Attaching the Antenna
Wi-Fi Antenna:
Screw in the Wi-Fi antenna to the front of the unit as shown in Figure 54.
NOTE: Using an external antenna is also an option. An external antenna can be plugged into the
SMA connector. The best antenna for the job depends on the range, topography and
obstacles between the two radios.

5INTERFACING MB485ETH-CG TO DEVICES
5.1 Device Connections to MB485ETH-CG
The MB485ETH-CG has a 3-pin Phoenix connector for connecting RS-485 devices on the R1 port. See
specific device bulletins for details on how to properly connect Modbus to each.
NOTE: Use standard grounding principles for RS-485 GND.
5.2 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)

5.3 Bias Resistors
To enable Bias Resistors, move both the BIAS- and BIAS+ dip switches to the right as shown in
Figure 8.
The MB485ETH-CG 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.

5.4 Termination Resistor
If the MB485ETH-CG 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 as 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.
