Data Connect IG144S SERIES


The Data Connect DCE/IG144S high-speed V.32bis security dial-line modems are designed and manufactured for rugged industrial applications over the Public Switched Telephone Network (PSTN). The DCE/IG144 utillizes the industries latest V.32bis modem technology to deliver outstanding features, performance, and reliability in one cost-effective solution.The DCE/IG144S modem are ideally suited for industrial communication applications including SCADA systems, RTS, traffic monitor and control, and industrial automation networks.The DCE/IG144S supports RTUs equipped with an EIA RS-232 or RS-485 serial port. Data communications speeds up to 14.4 kbps in reception and up to 9.6 kbps in transmission are supported.
The modems incorporate the latest data-compression and error correction standards for improved data transmission and reception over marginal and poor-quality telephone lines. Multiple levels of security with password verification and security call back keep your valuable data secure from intruders.The DCE/IG144S modems are powered by a wide range of AC and DC power supply voltages. Its low power consumption and low stand-by current technology design makes the DCE/IG144S ideal for a battery-powered system as well as regular AC powered operations.
