Leased Line Modems

SM19202FP Fast-Poll Industrial Grade Modem

for High Speed Multi-point Leased Line Communications

Back to top

The Synxcom SM19202FP and SM96202FP Fast Poll industrial grade leased line modems are designed and manufactured for rugged point-to-point and point-to-multipoint communication networks. Boasting the latest high-speed digital signal processing (DSP) technologies, the SM19202FP delivers a cost-effective 19,200 bps asynchronous solution with the industry’s first and fastest train time at 17.5ms. The SM96202FP operate at 9600 bps and below, has exceptional performance over unconditioned leased line and private lines. Both fast-poll leased line modems are ideal for multi-point communication applications including SCADA systems, RTUs, traffic monitoring and control, and industrial automation networks. Both modems support RTUs with EIA RS-232 or RS-485 serial port at speeds of 19200, 9600, 4800, 2400, and 0-1800 bps.

Key Features:
  • Ultra fast-train high-speed data pump with 17.5 ms or 23 ms RTS/CTS delay
  • Multiple data rates support over TELCO voice-band leased lines or private lines
  • DSP technology designed with automatic adaptive equalizer for fast synchronization and recovery
  • Limited distance modem mode operating 20+ miles over 19-26 AWG metallic circuits
  • High performance for point-to-point and multi-point polling networks
  • Isolated AC or DC-DC power supply for standard AC, battery, or solar powered systems
  • Flexible configuration by DIP switches, no AT command set required
  • Operate over wide range temperature of -40°C to +85°C
  • Supports RS-232, RS-485 and RS-422 interface

SM202T Industrial Grade Leased Line Modem

Bell 202 Compatible for Point-to-Point and Multi-point Applications

Back to top

The Synxcom SM202T industrial grade leased line modem is designed and manufactured for rugged point-to-point and point-to-multipoint communication networks. The SM202T modem utilizes FSK modulation and is compatible with all other industry standard Bell 202T modems. The modem operates in 4-wire full duplex or 2-wire half duplex over TELCO leased line or private lines. The modem’s build-in intelligent micro-controller support DTEs with full RS-232, RS485, or just the 3-wire (TD, RD, GND) interface. The modem is ideal for multi-point communication applications including SCADA systems, RTUs, traffic monitoring and control, and industrial automation networks.

Key Features:
  • Asynchronous operation from 0 to 1200 bps
  • Operate over TELCO voice-band leased lines or private lines
  • Operate over 4-wire or 2-wire leased line or private lines
  • Build-in micro-controller to support 3-wire RS-232 interface over switched carrier or constant carrier
  • Function as a limited distance modem operating 20+ miles over 19-26 AWG metallic circuits
  • Design for point-to-point and multi-point polling networks
  • Isolated AC or DC-DC power supply for standard AC, battery, or solar powered systems
  • Flexible configuration by DIP switches, no AT command set required
  • Build-in LEDs and loopback switch for local or remote diagnostics
  • Operate over wide range temperature of -40°C to +85°C
  • Supports RS-232, RS-485 and RS-422 interface
  • Small enclosure design for desk-top, DIN rail mounting or wall mount applications
