DB Series Nitrogen Generator
DB5-20 Model
5. Communications
Ethernet Communications – DB 5-20 generators come standard with an Ethernet Modbus TCP/IP
interface located along the bottom edge of the controller. The port comes preconfigured in DHCP
mode. The MAC address is located on the front of the controller located inside the control box and
can be used to map the controller to a static IP address within the DHCP server. Modbus-RTU is
available using a separate gateway device.
