Drivers for seemingly obscure UMC ethernet LC PDS E420 card

[BurntOutElectronics]

Hello all,
Keeping in mind I'm a relative newbie to vintage Mac gear (although I've already recapped the LC III motherboard and PSU), I can't for the life of me find information or drivers for this ethernet card that came in this computer.
I'm assuming I can't set it up in Mac os 7.5 until I have some sort of driver extension installed.

Here's the specimen.
I'd like to play around with this LC online a little, and perhaps set up a vlan and try Globaltalk which I've just stumbled upon.
Any help is appreciated.
Lance

Okay progress update.
I tried a different ethernet cable with the card, now getting a solid green light and I can see it pop up on my router with the fixed IP I assigned it on the Mac.
However when I try and ping the router or another computer it fails. When I try and ping the mac, windows tells me it's unreachable.

I tried both 56 and 32 byte packet sizes.
But it at least seems that the network card is working without an additional driver
