If you are using Topcon software Magnet or TopSurf (the testing version is enough), in this software is possibility to create virtual port as NMEA output. On ArcGIS mobile, in GPS Settings you must set GPS port on the virtual port you are created with proprietary baud rate.
Both programs must be running parallel. First you will run TopSurf, then you will press start key (longer time). After that you will run ArcGIS Mobile.
Hoping this will help you.
