DSP19.2 Fast Poll Modem

Data Connect DSP 19.2

Engineers who designed the original Telenetics DSP9612 in 1998 designed for DCE a new and improved DSP19.2 fast poll modem operating at 19200, 9600, 4800, 2400 and 1200 bps. The new DSP19.2 modem was tested to be 100% compatible with the Telenetics' DSP9612 at 9600bps and below. DCE begins to successfully shipping the DSP19.2 replacing the DSP9612 in early 2008.

High-Speed Fast-Poll Modem for Industrial Communications

The DCE Fast Poll modem is designed and manufactured from the ground up for rugged industrial communication networks. Boasting the latest innovative digital signal processing (DSP)-based communication device, the DSP19.2FP delivers a cost-effective 19200 bps asynchronous solution for point-to-point and multipoint connectivity. The DSP19.2FP Fast-Poll modem is ideal for industrial communication applications including SCADA systems, RTUs, traffic monitor and control, and industrial automation networks. The DSP19.2FP supports RTUs with an EIA RS-232 or RS-485 serial port at speeds of 19200, 9600, 2400, and 1200 bps. The DSP19.2FP Fast Poll modem is designed to operate over 4-wire or 2-wire unconditioned leased lines or private metallic circuits. For optimum performance, the modem employs QAM and FSK modulations to communicate over a variety of transmission lines.

The DCE DSP19.2FP Fast Poll modem is designed to operate with a wide range of AC or DC power supply voltages and temperatures. With proven reliability and ease of installation, the DSP19.2FP is ideal for point-to-point and point-to-multipoint polling networks, where high speed and low-network latency are critical for system performance.
