Primary Data Collection Point

The OleumTech® GP-DH2-W Wireless Gateway plays an integral role in the GP Sensor & I/O Network by being able to wirelessly collect critical process data from GP Wireless Transmitters and other Wireless Gateways. The data is stored in its 1920-point Modbus register holding table.

Serial Interface

With the provided RS232/RS485 Serial connectivity, the GP-DH2-W Gateway can virtually interface any third-party Modbus device for delivering data to the cloud. The GP-DH2-W can be configured as a Modbus Master, Modbus Slave, or LevelMaster ASCII Slave.

Peer-to-Peer Advanced Networking

In the GP 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 Transmitters and they have the ability to communicate with other Gateways in the network. With this powerful advantage, you can setup sophisticated I/O distribution systems and migrate data with extreme flexibility, scalability and ease.

Scalable Solution; Easy to Use

The GP-DH2-W Gateway can easily solve various I/O challenges with the help of OleumTech I/O Expansion Modules specifically designed for this device. You can utilize the 0-10 Vdc, 4-20 mA, and Digital I/O Modules in any mix and any combination to meet your I/O requirements. The GP Sensor Network allows you to take total command of I/O distribution by allowing you to easily expand and map just about anywhere within its network using its Gateways.
