The Synxcom Fast-poll industrial grade leased line modem is presented as the highest performance point-to-point and multi-point modem in the industry. It offers a polling time of 17.4 ms (RTS-CTS delay) over voice-band leased line or private line circuits. The multi-speed SM19202FP Fast-poll modem is now offered in desk-top, DIN rail mounting, or rack-mount configurations. The modem is appropriate for multi-point communication applications including SCADA systems, RTUs, traffic monitor and control, and industrial automation networks. The unit supports RTUs with an EIA RS-232 and RS-485 serial port at speeds of 19200, 9600, 4800, 2400, and 0-1800 bps. The SM19202FP Fast Poll modem is designed to operate over four-wire full duplex or two-wire half duplex unconditioned leased lines or private metallic circuits. For optimum performance, the modem employs QAM modulation, Viterbi coding scheme and FSK modulations to communicate over a variety of transmission lines.
