Application:
ATC-863/871/873 the Mini Power Wireless Module is used as the wireless data transmission in short distance.
With the small size, weight and power consumption and good stability and reliability, it has the function of bi-directional data sign ransmission, test and control.
It is used for Wireless meter reading, such as water meter, electric meter and gas meter, parking meter, intellective card, electronic weighing apparatus, meter for checking on work attendance, queue wireless meter, building control, shipping company control, alarm system, intelligent equipment, Automatic data collecting system; Industrial remote control and remote test building automation, safety and security, powerhouse equipment wireless monitor, entrance control
system, etc. It provides the USB power interface to be convenient for the mini computer and PC users if necessary.

ATC-863/871/873 wireless digital transmission module offers standard RS-232, RS-485 and UART/TTL level interfaces for direct connection with computers, use's RS-485 equipments, SCM or other UART parts.

ATC-863/871/873 has adopted half duplex communication channel
most suitable for point to multi-point communication mode. The primary station takes full control of communication harmony, and adopts data frames with address codes for data or command transmitting.
The secondary station shall fully receive them and select response by comparing address codes; all the work shall be fulfilled by upper layer protocols, which shall ensure that only one wireless module in the communication network is in the transmitting state in any instant to avoid mutual interference.
Therefore, the transmission channel built by ATC-863/871/873 is transparent to the user. ATC-863/871/873 can also be applied to point to point communication, making it easier and smoothly upgrade wire (RS232/485/TTL) transmission mode in original system.
