There are two separate modes:
- Serial Communications Mode: When the switch is in the “UP” position the reader is able to send tag data out of the micro USB socket. Use this mode when timing an event
- Mass Storage Mode: When the switch is in the “DOWN” position the reader is in mass storage mode meaning that the SD card can be recognised as an external drive as explained in detail in 21. Micro USB Socket. Use this mode when transferring data from your Micro-SD card to a PC.
