Interfaces

The central unit includes several communication interfaces.
LAN interface
The LAN interface can be used to establish a network connection between several SIMEAS R-
PMU devices and one DAKON or PDC (Phasor Data Concentrator).
The Baud rate is 10/100 Mbit/s.
COM 1, the data interface
COM 1 is a serial interface according to the V.24 or RS232C standard and is located at the rear
panel. It can be operated with Baud rates of 9,600 bit/s up to 115,200 bit/s (maximum cable
length 10 m). This interface is suitable for a direct connection via a null modem cable or for con-
necting an external data transmission module.
COM S, the service interface
COM S is a serial interface on the front panel according to the V.24 or RS232 C standard. It has
no control lines; thus, an operation only with software handshake is possible. The Baud rate is
19,200 bit/s.
The interface is located at the front panel and is used for service purposes.
Note
The transmission parameters (e. g., Baud rate) of the service interface are preset and cannot be
changed.
Printer interface
The parallel interface LPT 1 is provided for connecting a printer.
