Information about a firmware version, hardware version and a serial number can be browsed at the home page of a device web interface:


Serial Number – is a unique identification number of a device. It must coincide with a number at the sticker of a device. A serial number of a device cannot be changed.

Device Model – is a model name, which is indicated both on the body of a device and in a web interface.

Firmware Version – is a current firmware version, installed in a device.

A number of a firmware version looks like as follows: DKSF PPP.VV.SS.C-M (for example, DKSF 253.6.1.А-1), where:

  • DKSF – is a special prefix for all firmware versions of the company NetPing global Ltd.;
  • PPP – is a number of a device model, for which the firmware is designed.

 Project numbers usually, but not necessarily, coincide with a project number of a hardware of a device.

  • VV – is a version number. The versions are numbered, starting from 1. A version number is changed to the following one if the functionality is significantly extended or changed in the development process;
  • SS – is a subversion number. A subversion is changed at any firmware update, including bug fixing, updating internal modules, optimisation;
  • С – is a character, which indicates the type of this firmware version. А  is a stable Russian firmware version, В  is a version for testing or the first version of new firmware. E  is a stable version with English interface;
  • М – is a numeric suffix, which marks a modification (variant) of a device model, for which a firmware is designed.

Hardware version – is a version of a printing board and/or a configuration of the device.
