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.
