The only available without the keycode is the OAM port via ethernet eia/tia cable, ip address 10.10.11.1/255.255.254. Ethernet ports are not enabled without the initial keycode after a reset, the 2nd level reset, via the reset button at the port panel.
The software link to the vendor is obsolete so will look see for the algorithm vendor.
