DH1 BASE UNIT / DH2 WIRELESS GATEWAY
USER GUIDE
ADVANCED NETWORKING ARCHITECTURE
The DH1 Base Unit or DH2 Wireless Gateway plays a vital role in the OleumTech Wireless
Sensor Network. When used as a primary Gateway, it serves as the central collection point of
data, which then can be served to any Modbus Master device. A Wireless Gateway can
collect data from OleumTech wireless end nodes such as Wireless Transmitters and Wireless
I/O Modules in a “star network” or point-to-multipoint structure. What sets the OleumTech
Gateway apart from rest the competition is its ability to wirelessly share data and control
outputs amongst multiple Gateways in a same network known as “peer-to-peer”
architecture. Thus, OleumTech Wireless System is highly scalable, allowing the creation of a
basic network containing a handful of end nodes to a much more robust network containing
hundreds of wireless nodes and Gateways stretched by many miles.
FLEXIBLE COMMUNICATION
The Serial/RTU Port can be independently configured using BreeZ® software as a Modbus
Master, Modbus Slave, LevelMaster Slave, or ROC-Link Master. In a typical deployment, DH1
Base Unit/DH2 acts as a Modbus Slave device that is connected to a Modbus Master device
such as a RTU, PLC, HMI, DCS, or long-haul radio system over Modbus Serial RS232/485.
When used as a secondary Gateway, DH1 Base Unit/DH2 can also function as a Modbus
Master device to collect critical process values from a Modbus Slave device. The polled data
can be served to a Modbus Master device or can be shared across over the air to another
Gateway in a network.
