With the TinyTrak III, it's a configuration item (checkbox) in the setup menu.   This option is separate for the primary and secondary mode configuration. If you wish, you can even set the primary mode to 1200, the secondary mode to 300, and then switch-select them during operation. 

The OpenTrack requires downloading an entirely different set of firmware into the processor; i.e. not something you will do in the field.
