WAGO-I/O-SYSTEM 

750 

  

Busklemmen 

 

 

Attention

 

The data transmission takes place at 9600 baud (default value). 1 startbit, 8 
databits and 1 stopbit will be transmitted. No parity is available. The drivers 
are high ohmic. The control of data is made by the user software. 

 

Attention

 

The TTY Interface is passive in sending and receiving , thus having no 
current sources. For data conversion an active partner is needed or an 
additional current source has to be connected.
