Configuring Device Communications
4.3.1
Confirm the Device and MB485ETH-CG COM Settings Match
•
Any connected serial device
MUST have the same baud rate, data bits, stop bits, and
parity settings as the MB485ETH-CG.
•
specifies the device serial port settings required to communicate with the MB485ETH-CG.

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
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:
o
IP Address
o
IP port
o
TCP_ID
NOTE: This information is required for Section

Attaching the Antenna
Wi-Fi Antenna:
Screw in the Wi-Fi antenna to the front of the unit as shown in
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.
