Industrial Grade Bell 202T/V23 Modem for Reliable SCADA Communications

The Synxcom low-speed SM202T and SMV23 modems are designed and manufactured for rugged industrial communication networks. Both modems deliver cost-effective and reliable 1200 bps asynchronous solutions for point-to-point and multipoint connectivity. The SM202T/V23 modems are ideal for industrial communication applications including SCADA systems, RTUs, traffic monitor and control, and industrial automation networks. The SM202T/V23 supports RTUs with a user-selectable EIA RS-232 or RS-485 serial port at speeds up to 1200 bps. The SM202T/V23 modem is designed to operate over 4-wire full-duplex or 2-wire half-duplex over unconditioned leased lines or private metallic circuits. For optimum performance, the modem employs FSK modulations to be compatible with Bell 202T and ITU-V23 standards, which can communicate over a variety of transmission lines. The SM202T/V23 modem can operate over a wide range of AC or DC power supply voltages and temperatures. With proven reliability and ease of installation, the SM202T/V23 is ideal for point-to-point and point-to-multipoint polling networks, where reliability and low-network latency are critical for system performance.
