Firmware for a Zoltrix ZW444 device, with 140 probably marking a version or variant, labelled as tested OK, in a 1.89 MB RAR archive. The name gives little more, so identify the board and flash chip on your unit and compare them with the archive contents. A dump marked as tested suggests it was read from a working device and restored successfully. Keep a copy of the existing chip contents before programming, and verify the image size against the flash capacity.
