−  Use connector X11 or slot3 only for R-type extension I/O modules. 
−  Connectors X12 and X13 connect the SDCS-CON-F to the SDCS-PIN-F for voltage, current and 
temperature measurement. Additionally the firing pulses are sent to the thyristors trough the SDCS-PIN-F. 
−  Use connector X33 to connect the DCS Control Panel either directly via a 40 mm jack plug or via a CAT 
1:1 cable with RJ45 plugs.
