Fibre Link Connection 

The  fibre  optic  cable  is  connected  through  the  ST400  connectors.  To  connect  the 

ELO E171, the transmitter of the remote converter must be connected to the receiver of 

the local ELO E171 and the remote receiver must be connected to the local transmitter 

(fibres cross). 

Both converters must be set to the right data range and data format. The rotating switch 

on the top converter case is used to it. 

 

3.3 

Power Connection 

The  external  supply  has  to  have  the  output  voltage  of  12-24V  and  it  is  connected  via 

DC+ and DC- clamps. The supply take off is c.200 mA. If the supply is on operation the 

indicator RUN switches on.  

The converter contains two isolated zones. The RS-485 circuits are separated from the 

other ones and supplied via the internal isolated DC/DC converter. If it is necessary to 

keep this separation the external power supply must be isolated from the signal grounds 

of all RS-485 partners.
