How do I configure my Pluscom NAS 3.5" Drive (OSX)

I have recently purchased a Pluscom 3.5" SATA Network Drive to install on my home network. My plan is to (hopefully) use it for Timemachine backup and as a Shared Drive on the network.

I cant find any instructions anywhere to set this up on a mac.

The Drive is plugged into the network and I can see it in Finder however the password supplied with it (admin/admin) doesnt work.

I cant find the ip address for it either as there seems to be a browser based config panel - very frustrating!

Here are the only instructions I can find for this product.
