Re: gEDA-user: Looking for a gadget

Steve,

http://www.digi.com/pdf/prd_ds_digiconnectme.pdf

although only one RS232 line, but has 5 GPIO's  you can then switch which inverter you are talking to and gather the data in sequence

you could also get yourself a ENC28J60  or other easy to interface to ethernet controller  and a microcontroller of your choice

and build one.  make it a kit.... :-)

I'm looking for a simple gadget that can connect two RS232 ports

to an ethernet. I have a pair of solar grid-tie inverters in an

under-the-house utility room. I have ethernet down there but no

computers nearby and I would like to hook the RS232 monitoring

ports to software or a workstation upstairs. The plan is to put

up a simple system monitoring web page.

I know I can get some black-box TCP-IP port servers for a few

hundred dollars, but I would like to prefer something more open

if anyone knows of such a thing. At the price of the commercial

stuff, I can almost build my own from scratch (including a PCB!)

so I wouldn't be surprised if someone around here had some good

options.
