The ATC-871 is a short distance (500m/1640ft) wireless adapter for RS232, RS485, or TTL level signals. The ATC-871 provides 16 channels and baud rates up to 38.4K. The ATC-871 uses low power (max. 100mW) in the 429-433.30MHz frequency range.
Two ATC-871 are required for a communication connection. Select RS232, RS485, or TTL from the options menu as units only allow for one type of serial connection.
The RS485 version requires a RS485 configuration cable to send the the appropriate type of message (RS232,RS485) to set up the unit. The configuration cable is not included. See Related Products below.
