4.1.2 Power interface
The evaluation module has a power interface for the
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
4.1.4 RS-232
The evaluation module has a D9 connector for the standard
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.
