The Data Connect DCE/IG56S high-speed V.92 security dial-line modems are designed and manufactured or rugged industrial application over the Public Switched Telephone Network (PSTN) with security features such as password log-in and security call-back. The DCEIG56S utilizes the industries latest V.92 modem technology to deliver outstanding features, performance, and reliability in one cost-effective solution.

The DCE/IG56S modems are ideally suited for industrial communication application including SCADA systems, RTs, traffic monitoring and control, and industrial automation networks. The DCE/IG56S supports RTUs equipped with an EIA RS-232 or RS-485 serial port. Data communications speed up to 56 kbps 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 verifications and security call back keep your valuable data secure from intruders.

The DCE/IG56S 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/IG56S ideal for a battery-powered system as well as regular AC powered operations.
