I am trying to design a system/implement serial to Ethernet in a system. I found and have worked with the WIZ125SR in the last couple weeks. It is working very well for my application. For now we can integrate the entire dev board for a full system test/proof of concept. The end solution though is to implement with ICs directly into our main PCB design.
After further studying your products it looks like I can implement RS232 to Ethernet using the WIZ107SR schematic I found on the website. However, the WIZ125SR gives me two RS232 ports, the WIZ107SR only implements one RS232 port in the design. I could implement two of the WIZ7100A to be able to have two RS232 ports, however I’d rather implement the two-to-one functionality of the WIZ125SR into my system. Is it the W5100 or the ARM Cortex-M3 that handles the dual RS232 ports? Is the W5100 an upgrade on the W7100A? Any advice on how to implement the two RS232 to one Ethernet on my system PCB would be greatly appreciated.
