Overview of inner and outer interfaces

DSB45 is delivered in a sheet steel housing. All interfaces needed to meet basic test
requirements are accessible from outside (see Chapter 2.4.1 for an overview). A number of
additional interfaces are placed inside the housing (see Chapter 2.4.2).
2.4.1

Support Box.
All outer interfaces are protected against electrostatic discharge (ESD). The CE conformity
mark applies only to the closed DSB45 Development Support Box with the GSM module
mounted inside the metal housing.
