(Assuming we are talking a Windows system.)
I found a firmware update for the thing:
https://downloadcent...ander-RES2SV240
This is apparently v13. If you download it and unzip it you will see a folder called Windows. In the folder called Windows is:
CmdTool2.exe
The usage instructions for CmdTool2 are: http://download.inte...etool2_user.pdf
but it appears you open an elevated Command Prompt. Navigate to the folder then type:
CmdTool2 -AdpAllinfo -a0
and hit Enter and it should tell you all it knows about the thing which I presume includes firmware version.
(It's possible that the last part should be -a1)
The update instructions are in the same folder CMDTool2_Windows_v8.04.07_rel-notes.txt
