E.3 RS-485 Data Flow Control

 

The RS-485 standard uses a single pair wire to send and receive data. 
However, some controls to the direction of the data flow are required. 
RTS (Request to Sent) and CTS (Clear to Sent) are the most commonly 
used methods.

Intelligent RS-485 Control

 

ADAM-4510 and ADAM-4520 are both equipped with an I/O circuit 
which can automatically sense the direction of the data flow. No 
handshaking with the host (like RTS, Request to Send) is necessary. 
Any software, which is written for half-duplex RS-232, is compatible 
with an ADAM network without modification required. The RS-485 
control is completely transparent to the user.
