The transmission topology of the Modbus interface (connector X5) 
is set by means of the two configuration jumper blocks (J4/J5). The 
factory setting is RS485. 
In order to be able to use the Modbus interface as a point-to-point 
connection via RS232, you must remove all jumpers from block J4 
and plug them in on block J5.
