4.1.2 Power interface

The evaluation module has a power interface for the ACW-5 Nokia Power Supply. The input voltage range is 6.4 V - 13.5 V, and the absolute maximum rating is 16.5 V.

This power interface is not needed if power is supplied from the terminal through the M2M system connector. Alternatively, the evaluation module can supply the terminal through this same interface.

4.1.3 Service interface

The service interface in the evaluation module is a D9 female connector with an output voltage range of 0 – 3.3 V. This interface supports tracing the SW running in the evaluation module and downloading a remote-end application SW into the evaluation module. Controlling the evaluation module with a PC is also possible through this interface.

4.1.4 RS-232

The evaluation module has a D9 connector for the standard RS-232 interface. Through this interface, the developer can control the Nokia GSM Connectivity Terminal connected to the M2M system interface with AT commands. Through this interface the evaluation module can be used as a CORBA over an RS-232 adapter when testing the Nokia 30 terminal.

4.1.5 Digital output interface

One D9 connector in the evaluation module is reserved for digital outputs. There are 8 conventional digital outputs with HIGH and LOW states in a voltage range of 0 V – 3.3 V. LEDs on the evaluation module circuit board indicate the ON/OFF status of the digital outputs.

4.1.6 Digital input interface

One D9 connector in the evaluation module is reserved for digital inputs. There are 8 conventional digital inputs with HIGH and LOW states in a voltage range of 0V - 5V. These inputs also have a tolerance of 5 volts, for example for interfacing with 5V logic.

4.1.7 A/D and D/A converter interface

One D9 female connector in the evaluation module is reserved for A/D and D/A converters. There are two analog inputs with an input voltage range of 0 – 5 V and two analog outputs with an output voltage range of 0 – 3.3 V. Both directions are with high impedance but are not buffered.
