It possesses the ability to aggregate data from OTC wireless transmitters and I/O modules onto its 320-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 DH1 can virtually interface with any third-party Modbus device either as a master or slave device. 

The DH1 can also be configured as a LevelMaster ASCII slave or ROC Link master. 

Its dedicated RS485 port (RJ-45) can be utilized for connecting to another Serial device.

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.

The DH1 is equipped with onboard I/O, comprised of 4 analog inputs (0-5 Vdc), 2 digital inputs, and 2 digital outputs. 

If additional I/O points are needed, integrate the OleumTech RS485 Modular I/O Expansion System with the DH1 or any other gateway for added versatility.
