The RS-485 interface is needed for programming, parameterizing and di-
agnosis during startup operation and service procedures.
The RS 485 interface allows :
•
the implementation of a serial bus with up to 31 stations connected by
means of a twisted pair cable (half duplex mode),
•
a transmission length of up to 500 meters
•
data rates of 9600/19200 baud and
•
the implementation of a central PC-based visualization unit.
Via the RS-485 several DKCs can be put into operation with Drive Top
without reconnecting the interface cable.
To operate DriveTop with several ECODRIVEs, a RS-232/485 converter
is required between the PC and the drives.
The following application example displays a tested assembly with RS-
485 connection using the Phoenix Contact converter PSM-EG-RS232/
RS485-P/2D.
The Phoenix Contact interface converter PSM-EG-RS232/RS485-P/2D
implements the interface in a way suited for industrial use and for assem-
bly in cabinets.

Note:
The cable connection to the equipment must not be arranged
in a star topology but must be wired individually from one DKC
to the next.
The RS-485 requires a terminator on both ends. Both the ter-
minator integrated into the interface converter (180 Ohms) and
the pull-up and pull-down resistors (470 Ohms each) must be
activated. The other end of the cable must also be terminated
with a 180 Ohm / 0.5W resistor. The terminator is connected
directly to the DKC, plug X1, pins 4 and 5.
