The TDX-1150 wireless data transmission module manual provides specifications, interface options, setup procedures, and usage guidelines.
The TDX-1150 is a wireless data transmission module designed for applications such as wireless meter reading, industrial remote control, telemetry, and building automation. It offers 500 mW transmit power, GFSK modulation at 433 MHz, and selectable interfaces (RS‑232, RS‑485, UART/TTL) with programmable channels.
The manual explains how to power the module, connect the appropriate interface, configure parameters using the provided TDX parameter‑setting software, and operate the device in point‑to‑point or point‑to‑multipoint networks. Technical specifications, data‑transfer timing, and after‑sales support information are also included. This manual is written in Chinese.
| Modulation | GFSK |
|---|---|
| Working frequency | 433 MHz |
| Transmit power | 500 mW |
| Receive sensitivity | -116 dBm @ 9600 bps |
| Channel data rate | 9600 bps |
| Interface baud rates | 1200/2400/4800/9600 bps |
| Operating temperature | -25 °C ~ +60 °C |
| Power supply | 5 V DC (optional 3.3 V DC) |
| Dimensions | 70 × 46 × 12 mm (excluding antenna) |
| Transmit current | ≤ 500 mA |
| Receive current | ≤ 45 mA |
| Antenna interface | Rubber antenna (customizable) |

Parameters are set using the TDX parameter‑setting software via an RS‑232 connection; the software allows changes to channel frequency, baud rate, data format, and other settings.
In open line‑of‑sight conditions with the antenna mounted above 2 m, the module can reliably transmit over 1500 m at 9600 bps.
The module provides three selectable interfaces: TTL‑level UART, standard RS‑232, or standard RS‑485.
