The transmission parameters for the interface can be software-configured. Table 4 shows the
standard parameters for the RS232 interface.
Note:
•
If there is an USB/RS232 converter used on the PC/Notebook side, we recommend to
increase the „Char Timeout Multiplier" parameter in the COM-Port settings from „1" to
about „5".
•
IF there is a RS232 to TTL converter used without external power supply it may be nec-
essary to switch on the COM Port parameter "RTS" and "DTR" manually.
