DSP 19.2

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.
