This manual describes the HSD‑50T wireless data transmission radio produced by XLD Technology. It includes the device's technical specifications such as modulation method, frequency band, power levels, and environmental limits, as well as detailed wiring and interface information for TTL, RS232 and RS485 connections.
The guide also explains how to power the unit, configure parameters, send commands, and use low‑power sleep mode. It covers data transmission rates, channel selection, supported protocols, and provides the factory default settings for quick start. This manual is written in Chinese.
