C.3 Writing to the DTM-3237

To demonstrate the writing of a setting, we write 2150000000 to the setting Frequency (setting 3) of

category Tuner and demodulator settings (category 0x90). The command below assumes that

configuration settings are available in

DtmCmd.ini:

DtmCmd –w 0x90 3 2150000000

The parameters used in this command have the following meaning:

-i 0

 Set the index to 0.

-w

 Set the command type to write.

0x90 3 2150000000

 Specify command category 0x90, setting 3 and data 2150000000

This command results into the following output when using the

-v

parameter (verbose mode):

C.4 Upgrading the DTM-3237’s firmware

To demonstrate the firmware upgrade process, we pass the filename of the firmware file to DtmCmd.

The USB parameter (-usb) must be passed in case the USB interface is used. Please refer to §4.6.1 -

Firmware upgrade - Phases for more information about upgrading the firmware using the USB

interface. The command below assumes that configuration settings are available in

DtmCmd.ini:

DtmCmd -upgrade Dtm3237FwV0.dtm (for interface: I2C or serial)
DtmCmd -upgrade Dtm3237FwV0.dtm –usb (for interface: USB)

The parameters used in this command have the following meaning:

-upgrade

 Set to the filename of the firmware file.

Optional for USB:

-usb
