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.
