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.... :-) Steve On May 21, 2007, at 4:34 PM, Stephen Williams wrote:
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. -- Steve Williams "The woods are lovely, dark and deep. steve at icarus.com But I have promises to keep, http://www.icarus.com and lines to code before I sleep, http://www.picturel.com And lines to code before I sleep." _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
