Does anyone know of a editor software, or have a documentation, for config files from D-Link's DGS-series Smart switches?

I have a DGS-1100-26. A weird model, with a working but totally fucked up interface regarding VLAN config and I've been wondering if I could somehow alter the backup.cfg file and send it back to the switch with the desired settings. The file is in binary format with FM2 header. No tools known to me have any idea of this format, which I am aware could be (and probably is) proprietary.
