DH2 WIRELESS GATEWAY
Primary Data Collection Point
The OleumTech® “DH2” Wireless Gateway plays an integral role in the OTC Sensor & I/O Network by being able to wirelessly collect critical process data from OTC nodes including Wireless Transmitters, I/O Modules, and other Gateways. The data is stored in its 1920-point Modbus register holding table.
With the provided RS232/RS485 configurable Serial port, the DH2 can virtually interface with any third-party Modbus device either as a Modbus master or slave device. The DH2 can also be configured as a LevelMaster ASCII slave or ROC Link master. OleumTech offers Serial I/O Expansion Modules for use with the DH2 for added functionality.
Peer-to-Peer Advanced Networking
In the OTC Sensor Network, multiple Wireless Gateways can be placed into the same network to form a much larger sensor network. All Gateways can have their own set of end nodes and they have the ability to communicate with other Gateways in the network. With this powerful advantage, you can setup a sophisticated I/O distribution system and migrate data with extreme flexibility, scalability and ease.
