communications problems, use a lower baud rate or replace the 1203-SFC serial cable.
!
ATTENTION: Risk of injury or equipment damage exists. If the serial
converter module is transmitting I/O that controls the drive (indicated by a
solid green diamond LED), the drive may fault when you remove or reset the
module. Determine how your drive will respond before removing or resetting
a connected serial converter module.
