Trango Systems SDR900H Wireless Transceiver System

The Trango Systems SDR900H Wireless Transceiver System is a long-range, industrial-grade wireless link that transmits serial data over the 902–928 MHz ISM band using Frequency Hopping Spread Spectrum (FHSS). It is designed for video surveillance, PTZ camera control, industrial automation, SCADA systems, remote monitoring, and telemetry, enabling long-range wireless serial data communication between remote nodes and central control points. Key specifications include 1 W maximum EIRP RF output, 25 hopping channels, and real data throughput of 19.2 kbps, with serial data rates from 1,200 to 57,600 bps configurable in software. It supports RS232, RS422, and RS485 serial interfaces (DIP switch selectable), with 8-bit user-selectable addressing, and operates in an outdoor NEMA 4X aluminum enclosure for exterior mounting on poles up to 2-3/8 inches in diameter. The unit requires 6–13 VDC supply and offers half-duplex RF or full-duplex serial communication, with receiver sensitivity of -104 dBm at 10^-6 BER.
