Description
The Synxcom SMV23 industrial grade leased line modem is designed and manufactured for rugged point-to-point and point-to-multipoint communication networks. The SMV23 modem utilizes FSK modulation and is compatible with all other industry standard Bell V23 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.
