AC75 AT Command Set

2.14 AT^SCFG

s

<OtapTracer>(str)(+CSCS)

OTAP tracer

This parameter enables a trace output of the Java Over The Air procedure. The tracer is useful for obtaining additional information when setting up an OTAP scenario. The output is provided on the interface on which the command was entered. While the tracer is enabled the interface is used for trace output only, meaning that no AT commands can be entered. The tracer will be switched off only by a reset of the module, e.g. after a com- pleted OTAP procedure.

“1“ Enable OTAP tracer.

<deviceDescr>(str)(+CSCS)

Device Descriptor

This parameter determines whether to use the Siemens standard USB Device Descriptor configuration (default) or a Device Descriptor configuration customized by the application manufacturer.

Parameter is global, stored non-volatile in ME and not reset by AT&F. Setting will be active after AC75 restart.

“0“(D)	Siemens standard USB Device Descriptor.
	If <deviceDescr>=0 is set all other parameters related to "Serial/USB/DDD"
	cannot be changed. For use in a Windows environment, the "usbmodem.inf"
	file delivered with AC75 shall be present.
	Note that whenever the AC75 firmware is updated over the USB interface the
	Siemens standard configuration must be present. Therefore, before starting a
	AC75 firmware download be sure that <deviceDescr>=0 is activated and,
	under Windows, the Siemens "usbmodem.inf" file can be found. Remember to
	restart the ME after reverting to <deviceDescr>=0 and before starting the
	firmware download.
“1“	Customer specific USB Device Descriptor.
	If <deviceDescr>=1 is set all other parameters related to "Serial/USB/DDD"
	can be changed.
	Customizing the USB Device Descriptor configuration requires a unique Ven-
	dor ID obtained from the USB Implementers Forum. For information please
	refer to http://www.usb.org.
	For use under Windows a customized INF file for the USB modem must be
	present. An easy way to create this file is copying the Siemens "usbmodem.inf"
	file and overwriting the equivalent values changed with AT^SCFG, usually at
	least the Vendor ID, Product ID and, optionally, the manufacturer string. This
	is because the strings given for the customized "Serial/USB/DDD" parameters
	must be identical with those contained in the INF file.
<descrIndex>(str)(+CSCS)
Descriptor Index

As the AC75 shall be capable of holding 0 - 3 customized Device Desciptor configurations, the <descrIndex> allows to create and select different parameter sets consisting of the parameters listed below.

Please note that AC75 Release 01.002 supports only one parameter set associated to value 0.

Parameter is global, stored non-volatile in ME and not reset by AT&F. Setting will be active after AC75 restart.

“0“(D)	Index for the first descriptor definition.
“1“	Future use.
“2“	Future use.
“3“	Future use.
