OPERATION
The MA-490’s Data Port is used to connect to the Common Module’s or other equipment’s serial port.
The MA-490’s Craft Port is used to connect to the PC’s serial port. The Craft Port has two different
modes: April mode and Console mode. April mode is used to setup the MA-490’s configuration
parameters. Console mode is used to tie the Craft Port and the Data Port together so they behave like
one serial port as shown in the figures below. When the MA490 is in the Console mode, the user can
type a “Ping” command through the Craft Port to ping a remote PC.
