Appendix B: Configuration ProfilesQuick Setup Factory Profiles
For quick setup, the MTA128ST-USB includes six Quick Setup Factory Profiles, each of which is
configured for a specific type of port operation. You can load a Quick Setup Factory Profile into active
memory by using the command
&Fn,
in which
n
is the number of the profile you wish to load. If you
wish, you can then customize the profile and store it, using the
&W
command, so that it loads
automatically when the MTA128ST-USB is turned on or reset. These profiles are stored in permanent
memory and are not user-configurable as such.
&F0
Profile 0Modem-like operation (default)
&F1
Profile 1V.110 async operation
&F2
Profile 2V.120 async operation
&F3
Profile 3X.75 async operation
&F4

Note: The &F1 command will return an error when used with build MT128ST-USB-RC.
