On Windows, you can use DtInfo to upgrade the DTA-2172 to the latest available firmware.

Note

DtInfo cannot be used to downgrade to a previous firmware version. Use DtEpc for that.

Instructions

Start DtInfo on a PC containing the DTA-2172. If the dialog indicates that new firmware is available, press Upgrade. The on-board flash chip will be reprogrammed; this will take a while (about one minute).

Warning

To avoid permanent damage, DO NOT turn off the PC while upgrading with DtInfo.

DtEpc is a command line tool for flashing any firmware version from the table at the right. DtEpc can be run on Linux and Windows.

Instructions

1.	Download the desired firmware version and unzip. Launch a command prompt in the directory where you put the firmware.
2.	If the system contains multiple cards, list the devices in the system using command:
	dtepc -d 0
	Identify the device ID of the card to be flashed; this will be '1' if there is only one device.
3.	Flash the firmware:
	dtepc -d 1 -ps Dta2172_v2.rpd
	(use e.g. -d 2 if device ID is 2.)
4.	Activate the new firmware.
	- Run the following command:
	dtepc -d 1 -b
	- On Linux, reboot the PC.

Warning

To avoid permanent damage, DO NOT turn off the PC while running dtepc ‑ps.

You can download DtInfo and DtEpc from the Downloads - Utilities page.
