RS-485 interface
The RS-485 interface enables:
•
the implementation of a serial bus with up to 31 participants connected
via a two-wire line (half duplex mode), i. e., it can be used to start up
several DKCs with DriveTop without having to plug into a different
socket of the interface cable,
•
a transmission length of up to 500 meters,
•
transmission rates of 9600/19200 baud and
•
the implementation of central PC-supported visualization unit.
As a matter of principle, there are two solutions for operation with RS-485:
•
RS-232/RS-485 converter between PC and drives or
•
RS-485 plug-in card in PC.
Note:
Please contact your PC supplier to find the solution for your
application.

1):
Connector outer screen to ground potential (strain relief of metallic
connector case) on PC side and on device.
2):
Connection of device ground with the connector case with the fixation
screws of the connector.
3):
If the drive controller is fitted as the geometrically last participant of a
RS485 bus, activate the bus termination.
