    It looks like this referenced a function, join-string not included in the script, so I changed the following line to use the -join method instead:

    #$FirstByte = Join-String -Strings “0x”, $HexProductState.Substring(0,2)
    $FirstByte = -join (“0x”, $HexProductState.Substring(0,2))

      thanks mate, you are right. Updated the function to use your construct.
