A bit OT for the group, but it is related to an embedded system ...
I have an application that requires Ethernet to be extended through an existing RS485 serial link, such that I have Ethernet RS485 Ethernet.
I'm aware that there are any number of copper wire Ethernet extenders that will work on bare copper, but unfortunately I have the serial link in the path so I can't get to the bare copper at all.
I also know that there are any number of Ethernet->Serial conversion boxes, but they all seem to be one-path units for converting something that was serial I/O to sit on a LAN. Neither of these things is what I want.
Is there anything I can buy to complete the link? I'm not quite sure what I should be looking for or asking Google for! I know I could build something to do what we need, but I'd rather not if possible.
