Functions of the modules
 CPU: Control of all device-internal processes, the communication with external devices and
the data processing
 DAUs: Measured value acquisition and processing of measured values in lines connected to
the DAUs
 Power supply unit and battery package (option): Infeed of the supply voltage, distribution in
the SIMEAS R-PMU and optional uninterruptible power supply
External communication interfaces
 LAN (rear panel): Network connection (LAN) for the data transmission between SIMEAS R-
PMU and evaluation PC, DAKON or PDC
 COM 1 (rear panel): Serial interface for the transmission of parameters and measured data
between SIMEAS R-PMU and evaluation PC, DAKON or PDC
− via direct coupling
− via external analog modem / ISDN modem
− via FO converter and star coupler if several devices are connected (no connection to
PDC possible)
− via X.25 communication (no connection to PDC possible)
 COM S (front panel): Serial service interface for the parameterization and transmission of
measured data from the SIMEAS R-PMU to the evaluation PC or DAKON
 LPT 1 (rear panel): Parallel printer interface
 7B1(+), 7B2(-) (rear panel): Connection for the GPS timer for synchronization
 Binary and relay outputs (rear panel)
