10.4 COM 1 Interface
10.4.1 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: 9,600 bit/s to 115,200 bit/s
Data bits: 8
Stop bit: 1
Parity: none
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.
Then set the corresponding interface parameters in the Parameterize PC module of the
OSCOP P software.

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).
