Application Information

1.When designing fixed reader with CF-MU940, please take care of heat sinking and remember to make sure the heat sinker of the module is closely and stably attached to the reader’s bottom plate;

2.ANT1 is the default antenna port. Please pay attention to antenna port’s definition.

3.Please refer to CF-MU940 user’s manual for detailed protocol description.
