The GWNP includes two sets of DIP switches, as shown in the Product Diagram section. The DIP switch labeled
“ADDRESS” is for addressing. The DIP switch labeled “CONFIG” is for communications configuration.
Address Configuration
Each device on a single network must have a unique address. Set the DIP switch labeled “ADDRESS” to assign a
unique address before the device is connected to the network. If an address is selected that conflicts with another
device, neither device will be able to communicate.
Address the GWNP as any whole number between and including 1 to 127. Note that zero is not a valid address
for Modbus; zero is a valid address for BACnet. Positions 1 through 7 of the “ADDRESS” DIP switch designate the
address. Position 8 toggles between the Modbus and BACnet communication protocols, as shown in the diagram
below.

To set an address using the DIP switch, simply add the values of any switches that are in the ON position.
For example, an address of 73 is set as shown in the diagram below.

Position number 1 has an ON value of 1, position number 4 has an ON value of 8 and position number 7 has an ON
value of 64 (1 + 8 + 64 = 73).
Communications Configuration
See the Product Diagram section for the location of the DIP switch labeled “CONFIG”. The following parameters are
configurable:
• Parity (Modbus only): None, Odd, None1 (one stop bit), Even
• Baud rate: 8600, 19200, 38400, 57600 (Modbus), 76800 (BACnet)
• Autobaud: On, Off
Note: Autobaud may not be able to automatically determine the baud rate in some situations. In this case, set
Autobaud to OFF and use the manual baud setting.
