Once the project has been transferred from the PC to the VT, the VT
may now be connected with several drives. This connection may be
made either by connecting directly as described next or through the
“RS232/RS422 BE” adapter that will make the connection a lot easier
for the user. In either case, communication must be established
through the MSP serial port of the VT (port A when using the
adapter) and the RS-232/422 serial port (B port when using the
adapter) of each drive.

INFORMATION. Any CMC drive may be configured with an
RS-232 serial line and SERCOS-II or CAN interface or with
an RS-422 serial line.
RS-232 MODE. To establish serial communication via RS-
232 between a VT or a PC and the drive, the arrow of the
rotary switch of the drive module musy be pointing at the 0
identifier.
RS-422 MODE. To establish serial communication via RS-
422 between a VT or a PC and the CMC drive, the arrow of
the rotary switch of the drive module musy be pointing at an
identifier other than 0. When having several drives, assign
the identifying node using the rotary switch. A reset is
required to validate any node number change at the rotary
switch.
