Serial Direct Connection

Use the 9-pin RS232 connection at the rear panel of the SIMEAS R-PMU for the serial
transmission of parameters and measured data. This serial interface can be used to set variable
baud rates.
Baud rate:
Data bits:
Stop bit:
Parity:
For communication between the SIMEAS R-PMU and PC/notebook or PDC, the data line must
be connected both to the data interface at the rear panel of the SIMEAS R-PMU and to the
corresponding COM port of the evaluation PC/DAKON or the PDC.
Note
Note that while using the serial connection (null modem) for transferring PMU data to the
PDC a concurrent communication to OSCOP P (Evaluation PC/DAKON) is not possible.
For null modem communication to the PDC, the PPP protocol is used (see
section 12.14.2).
Then set the corresponding interface parameters in the Parameterize PC module of the
OSCOP P software.
