Micro SD Card

Use this option to replace the bus coupler if there is a micro SD card installed in the existing bus coupler.

Prerequisite: This option is valid only to replace a bus coupler which has stored data on a micro SD Card (that is, the SD Card visual indicator on the Bus Coupler being replaced has been in the Green, Steady On state).
