3.1.3 Digital Output
•
switch voltage is VIN; high side switch
•
max. Output 400mA
•
short circuit protected
•
ESC protected
•
under full control of embedded application
The following command has to be used to initialise and to set the digital output:
AT#GPIO=3,1,1 switch output on
AT#GPIO=3,0,1 switch output off
3.2 Power Consumption
The measurement was realised by 4 different Voltages (5 V, 12V, 24 V and 32 V). The Terminals were
connected via RS232 cable with the PC in order to receive at commands. The temperatures were
achieved with the help of temperature chamber. The voice call with Power level 5 in GSM 900 was
established with a GSM Tester.
