9XTend™ OEM RF Module - Product Manual v2.x6x

Automatic DIP Switch Configurations

Each time the module assembly is powered-on, AT commands are sent to the on-board RF module

as dictated by the positions of the DIP switches. DIP switch configurations are sent automatically

during the power-on sequence and affect module parameter values as shown in the table below.

Note: The results of SW 2, 5 & 6 ON and SW 5 & 6 ON are the same.
