ExtendNet ESI-2811 manual

[stensland]

Hey,

so I'm looking for a manual for an ExtendNet SX ESI-2811 from Extended Systems. The company was bought out back in 2005 and our company uses the 10BaseT to Parallel for our older label printing machines. I was wondering if anyone either knew how I could get a-hold of a manual for one of these things.
Thanks,

Stensland
