Need to Upgrade

Light Manager can be run inside Hyper-V, which is windows virtual machine system. You will likely need a WinXP or previous license to get the OS installed. Enabling and setting up Hyper-V is a bit complex so you might want to find an IT guy with a decade or more of experience. I've also heard of people just holding onto an XP based system just to run LM. They are plentiful and fairly cheap in the used market.

The once was a networked version of the Unison processor. With that one could use Light Manager and upload the files on a network. However finding one and making it work on your system might have some surprises in store. My suggestion is to call tech support with as much information on your system as you can find. (Job number, notes from the config, other devices info, etc.)

There are a few virtualization solutions that work well. I prefer Vmware Player with a 32 bit Windows 7 installation. Windows Virtual PC (Microsoft's solution) also works fairly well.

Oracle’s VirtualBox is another alternative for running LM that is freeware, but none of this eliminates the basic road block of the 3.5 floppy. The previously mentioned CME or CMEd with “network” port really only allowed Net2 data out to talk to gateways and I don’t believe even had a web interface. I do not recall ever successfully uploading anything other than possible RS232 commands over that Cat5 port and there’s nothing in LM that iniialtes that connection that I’ve ever seen. All of that to say, no, not really. If you want to move your control to 2018, you’re looking at replacing that ERN and all stations. Sorry.
