I'm the lead developer for "Image Scan! for Linux", a simple graphical

A network setup could be made to work by setting up `saned` on the
server machine to accept connections from the client.  On the server
side, `saned` would access the device through a backend that supports
the RX685.  On the client you can then use any SANE frontend via the
SANE net backend.

I'd try using the device on the server machine directly first with a
simple SANE frontend like `scanimage` first.  Next, try using it via
localhost and `saned`.  If that all works, try it from the client.

Note that network related restrictions (tcpwrappers, packet-filtering)
may all get in the way before you even get to the SANE part of the

Which backend are you using?  I'd hazard a guess that the RX685 works
fine with the same backend.

At least the external `epkowa` backend is known to work (but has never
been tested on the Mac, AFAIK).  It is part of "Image Scan! for Linux"
and available at:


For the RX685 no non-free binary-only parts are needed.
