Hello, in my work We bough a couple of WIZ107SR R1.4 2013-11-11, firmware 4.06 to try them and evaluate if we can use them in our prototypes. I´m trying to configurate them as server. I used the config tool v18.104.22.168 and configurate the module as server, IP assigned by DHCP, all other things as default. I opened the Hercules or hyperterminal and connected to the device on port 50001. Everything seems to be ok to this point…but… when I try to send something from hercules/hyperterminal I can´t see anything on TX… just plain -5V… no conmutations at all. Ethernet side responds to ping. Also connected TX and RX together to see some kind of loopback… but nothing happened.
Vcc connected to 3.3V
nRESET connected to 3.3V
I tried two WIZ107SR with no luck. It looks like I missed something but can see what it is. Can you help me?
