Tribestar SwitchMonitor Software?

I stumbled upon a Tribestar Localtalk to Ethernet bridge (supports Mac IP and everything.) It's just the main box, though. I still have to find an AC adapter for it. I did find the manual online pretty easily. However, when I do a Google search for the Tribestar SwitchMonitor software, I get nothing but links to warez and questionable websites from which I wouldn't dare download.

Anyone know of a good website to download the software? I checked MacGUI City and Macintosh Garden to no avail.
