[Introduction]：The E96-DTU(400SL30-485) is an industrial-grade wireless data transmission unit (DTU) based on the Semtech SX1262 LoRa chip. Operating at 433/470MHz with military-grade LoRa spread-spectrum modulation, it provides a transparent RS485 serial interface for seamless integration with PLCs, meters, sensors, and SCADA systems. The DIN-rail plastic enclosure, wide voltage input (AC 85–265V or DC 8–28V), and -40℃ to +85℃ operating range make it ideal for demanding industrial environments.

Frequently Asked Questions
Q: What is the actual transmission range of the E96-DTU(400SL30-485)?
A: In an open field with standard 3dBi antennas at 2m height, the E96-DTU achieves approximately 3 km. Range varies with environment: urban/obstructed areas typically yield 0.5–1 km, while elevated antenna placement can extend coverage further. The SX1262 LoRa chip’s spread-spectrum modulation provides strong anti-interference performance in noisy industrial RF environments.
Q: How do I configure the E96-DTU? Does it require software?
A: The E96-DTU is configured via AT commands over the RS485 interface, or using Ebyte’s free Windows configuration tool (RF Setting). Parameters include frequency channel, TX power, baud rate, address code, and working mode. No programming is required — the DTU operates transparently once configured, passing RS485 data wirelessly without any host-side protocol changes.
Q: Can the E96-DTU support multi-point (point-to-multipoint) networks?
A: Yes. The E96-DTU supports point-to-point, point-to-multipoint, and multi-level relay network topologies. Up to 65536 address codes allow large-scale network segmentation. LBT (Listen Before Talk) is supported for compliance with duty-cycle regulations in EU433 environments.
Q: What power supply options are available?
A: The E96-DTU accepts AC 85–265V (110V or 220V mains) or DC 8–28V via the terminal block. This wide voltage range makes it compatible with standard industrial control cabinets, DIN-rail power supplies, and solar/battery-powered field installations.
Q: Is the E96-DTU compatible with Modbus RTU / SCADA systems?
A: Yes. The E96-DTU provides a fully transparent RS485 serial link, meaning Modbus RTU, DNP3, and other RS485-based protocols pass through without modification. Your existing SCADA or PLC software communicates exactly as if the devices were wired, with no gateway or protocol conversion required.
