7.4.2) 

RS 485 CONNECTION SHIELDED 

Although the signal is given by the difference between A and B voltage, a ground connection is 
needed to eliminate or to reduce the common mode noise induced (into the bus). 
To reduce the EMI interferences need to connect the shield directly to a ground at one end and with a 
series RC network at the other end. 
R = 100

Ω

 C = 33µF. 

The max length of the stubs is 20cm. 
 

7.4.3) RS232 

CONNECTION 

If a RS232 communication line is shorter of 5 mt. and a multidrop network will not use, it’s not 
necessary to use a serial line converter because the serial output is compatible with the PC, as shown 
on the above mentioned picture. A RS232 could reach 15mt. but the presence of noises in the 
industrial application could cause breakdown in the communication. 
The connection from EMA serial port RS232 to PC RS232 serial port is a PTP, Pin To Pin, connection.
