The OleumTech® DH2 Wireless Gateway plays an integral role in the OTC Wireless Sensor and I/O Network. 

It possesses the ability to aggregate data from OTC wireless transmitters and I/O modules onto its 1920-point register holding table. 

Third-party devices can access the data over the Modbus or LevelMaster ASCII protocol.

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.

Deploy multiple gateways to the OTC platform, creating a custom, highly scalable network. 

The gateways have the ability to communicate with one another.
Leverage the peer-to-peer technology and funnel data to the primary gateway, optimizing network efficiency and/or designing an extremely flexible I/O mapping system across the entire wireless network.

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.
