DTI 1100 Series

The DTI 1100 is a revolutionary low-cost approach to the implementation of field devices that require NTCIP conformant communication. The very small size and powerful performance of the DTI 1100 controller makes it the perfect engine to control small signs, traffic count systems, weather stations, cameras or any custom application where NTCIP communication is required.

The module is provided with NTCIP communications built in, so the only custom development required is the interfacing of the module to the applicable field sensor or output device. A full-function RS232 connector at one end allows interfacing via modem to a central computer, while the serial port at the other end is connected to the field device. On-board jumper-selectable RS485 provides the flexibility to manage a network of IDI 1100’s on both serial ports.
