MC35i AT Command Set

MC35i AT Command Set17.5 AT^SSYNC17.5 AT^SSYNC Configure SYNC PinThe AT^SSYNC command serves to configure the SYNC pin of the application interface. The applicability of thedifferent types of is product dependent:• If you have a MC35i module you may select either mode, depending on whether your application is designedto use the SYNC mode (indicates the current consumption in a transmit burst) or the LED mode (drives astatus LED connected to the pin). See [2] for further details on both modes.• In the case of the MC35i Terminal the AT^SSYNC command is intended only to control the status LED placedon the front panel. Therefore, the SYNC mode (=0) is not applicable. Further details on the LED canbe found in [3].SyntaxTest CommandAT^SSYNC=?Response(s)^SSYNC:list of supported sOKRead CommandAT^SSYNC?Response(s)^SSYNC:OKWrite CommandAT^SSYNC=Response(s)OKReference(s) PIN ASC0 MUX1 MUX2 MUX3 Last-- ! % % % % ! !Parameter Description (num) 9/10/08Operation mode of the SYNC pin. Setting is stored non-volatile.0 (D) SYNC mode:Enables the SYNC pin to indicate growing power consumption during a transmitburst. You can make use of the signal generated by the SYNC pin, if powerconsumption is your concern. To do so, ensure that your application is capableof processing the signal. Your platform design must be such that the incomingsignal causes other components to draw less current. In short, this allows yourapplication to accommodate current drain and thus, supply sufficient current tothe GSM engine if required.Note: =0 is the factory default of the MC35i module. In the case of theMC35i Terminal this mode is not applicable and should not be selected.1 LED mode:Enables the SYNC pin to drive a status LED installed in your applicationaccording to the specifications provided in [2].The coding of the LED is described in Section 17.5.1, ME status indicated bystatus LED patterns.Note: =1 is the factory default of the MC35i Terminal.MC35i_ATC_V02.00nConfidential / ReleasedPage 356 of 390
