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
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.
Reasons to Buy the DSP19.2 Fast Poll Modems
The DSP19.2FP fast poll modem utilizes the latest digital signal processing (DSP) technology to accomplish the high speed data rate at 19200, 9600, 4800, 2400 and 1200 bps. The DSP19.2 is the only product in the market (and the world) that can achieve a 17.4 ms training time at 19200 bps and 23 ms at 9600 bps or below. This performance is critical for multi-point polling applications.
The DSP19.2FP modem is 100% backward compatible with the Telenetics DSP9612FP plus the additional 19200 and 2400 bps operation.
The DSP19.2FP is implemented with a high speed DSP processor that is performing 60% faster than the DSP9612, the data rate is 100% faster than the DSP9612.
The DSP19.2FP has additional features to support SCADA equipment that does not provide the full RS-232 or RS-485 control signals.
The new modem has a smaller foot-print (30% smaller) and consumes less power.
The new modem will support 10 to 60 volts DC power supply, or can be powered by a factory provided AC to DC converter from 100 to 240 VAC or 100-400VDC. This will reduce customer’s inventory of modems and saving cost by stocking only one model instead of two models.
The new modems will support both RS-232 and RS-485 interface.
The DSP19.2FP modems can be rack-mount (DSP19.2-RM) or can be panel mounted or DIN rail mounting with the optional DIN rail mounting kit.
The designers of the original Telenetics DSP9612 fast poll modems are now the founders and creators of the new DSP19.2 fast poll modems. These engineers are the most knowledgeable people available today to help your technical issues. They will stand behind the product and support of the DSP19.2 modems for any future applications, update and enhancement. DCE does not expect to continue to offer future enhancements or updates to our older DSP9612 products. Problem solving and the ability to support new applications will be found only in the new DSP19.2FP products.
Supports will be provided for repair, diagnose and analyze of your installation, network connections and equipment.
Technical support will be provided for optimum performance with your network and potentially save time and cost in your operation
Customize the product hardware and firmware to meet your specific applications or enhance your system performance.
The Bottom Line
Why risk buying older technology products that could harm the integrity of your network performance when current technology is available with full backward compatibility? The DSP19.2FP is specifically built for harsh environment and is most reliable for industrial applications that will be saving cost in the long run.
