Dip Switches - MTX -4G-JAVA-IoT Hardware User's Manual

6. DIP switches

The MTX-Java-IoT modems include 8 DIP microswitches allowing the user to configure some functionalities
of the device. These switches are located close to the SIM card holder, so you can access them through
the same removable panel of the SIM card holder.
By default, all switches are delivered in OFF state. In the following picture you can see them in their
default OFF state with their corresponding numbers:
