This manual describes the ATC-863 low-power wireless data transmission module, covering its features, interface definitions, power settings, parameter…
The ATC-863 is a short-range wireless data transmission product designed for applications such as water, electricity, and gas metering, parking meters, access control, and intelligent instruments. It features low power consumption, high reliability, and high anti-interference capabilities, supporting RS-232 and RS-485 interfaces with multiple power and sleep modes.
The document details the module's usage, including interface definitions for DB9 connectors and terminal blocks, power requirements (9-12V DC), and parameter configuration via software. It also lists technical specifications such as transmission power, sensitivity, and operating frequencies, along with a troubleshooting guide for common issues like transmission distance and error rates. This manual is written in Chinese.
| Transmission Power | 100mW |
|---|---|
| Receive Sensitivity | -121dBm |
| Operating Frequency | 433MHz |
| Operating Voltage | 9-12V |
| Operating Temperature | -20℃～55℃ |
| Dimensions | 95MM×76mm×18MM |
| Sleep Current | <1uA |
The module supports communication rates of 1200, 2400, 4800, 9600, and 19200 Bit/s.
In hardware wake-up mode, the module enters sleep when the SLE pin (RS-232 pin 9) is high and wakes up when it is low.
Under line-of-sight conditions with an antenna height greater than 3 meters, the reliable transmission distance is greater than 300m at 9600bps.
