Sixnet N3752 Modem

Sixnet N3752 Modem is an industrial VT-Modem from the Sixnet VT-Modem family, designed for remote telemetry and industrial automation where a field device must talk to a host computer over a telephone line or other dial-in link. It offers an RS-232 or RS-485 serial interface for direct connection to sensors, PLCs, or RTUs, enabling straightforward data collection and remote control. In the VT-Modem family, certain models are specified for data rates up to 33.6 kbps (33600 baud), with other variants providing higher rates; the VT-MODEM-3WW listing documents 33600 baud with RS232/RS485 ports and Modem Telephone Line operation. This family is marketed under the Sixnet and later Red Lion brand lineage, reflecting its heritage as a rugged, standalone industrial modem intended for remote communications at sites without reliable local networks. The VT-Modem line is commonly used in remote telemetry, SCADA, and equipment monitoring applications where a durable, self-contained communications device is connected to a central supervisory system via dial-up or leased-line networks.
