RS232 Wireless Module – 300m
The ATC-863 wireless digital transmission module provides standard RS-232, RS-485, and UART/TTL interfaces for direct connection with computers, RS-485 equipment, SC, or other UART devices.
The ATC-863 adopts a half-duplex communication channel, making it suitable for point-to-multipoint communication modes.
In this setup, the master station fully controls communication coordination and uses address-coded data frames for data or command transmission. Slave stations must receive these frames and respond only when their address code matches. To prevent mutual interference, upper-layer protocols ensure that only one wireless module transmits at any given time.
Thus, the transmission channel established by the ATC-863 is transparent to the user.
It can also be applied to point-to-point communication, allowing an easy and seamless upgrade of existing wired (RS232/485/TTL) systems to wireless transmission.
