General
The 6KCV300CTI interface allows the connection of a PC to AV-300, DV-300 and DGF card using the
RS485 port.

The Interface can be connected directly to the RS232 serial line of the PC, and through a standard
9 pin cable to the XS connector of the Drive or the DGF board.
The interface allows two type of connection:
• Point to Point Connection
• Multidrop connection
Point to Point connection
This type of connection can only be used for direct communication of the PC to the Drive and its
options, using software configuration tools designed for this purpose. Do not use 6KCV300CTI for system
control or monitoring. The maximum cable length is of 2 meters from the PC to drive.
The board is powered from by means of the communication line RS 485 through the XS1 connector
with a +5V (±10%) referred to GNDD. The supply is provided by the Drive regulation board or by the DGF
card. See section 6 to properly set jumpers
The Interface converts the RS232 of the full duplex serial line of the PC into the RS485 of the half
duplex serial line of the Drives. The management of the RS485 device is completely automatic and it does not
require any software control.
The Interface has two dip-switches for the insertion or disconnection of the terminating resistors. For
the Point to Point connection these switches must be set in OFF position.
To configurate the 6KCV300CTI Interface as Point to Point, it is necessary to connect it to the Drive through a
standard cable. To do this, connect directly pin to pin all the single wires (9 wires) or at least the pins 3, 4, 5, 7
and 9 (5 wires) of the connectors XS1 (CV300CTI) and XS (Drive or DGF).
