The serial ports are electrically not separated. If the system reports ’earth leak’ after the external device is
connected, the following action can be taken:
S remove the ’earth leak’ at the connected device or
S use a special separation module (RS232 to RS232) only for temporary application (SWE/VISU)
S remove temporarily
jumper ’ST2’ on the master bord
S connecting information see page 37/40
