RS232 Wireless Module – 500m
The ATC-871 is a short-range (500m) adapter designed for RS232 or TTL communication.
It offers 16 selectable channels and a baud rate of 28.4Kbps, operating in the 429–433.30 MHz frequency range with low power consumption (max. 100mW).
It is used for general wireless communication applications.
From the menu, users can select RS232, RS485, or TTL mode, allowing only one serial interface to operate at a time (two different serial signals cannot be transmitted simultaneously).
Supported interface models:
-
ATC-873-S0 – TTL interface
-
ATC-873-S1 – RS-232 interface
-
ATC-873-S2 – RS-485 interface
