The pinout for the WIZ-IP20 is incorrect.

Question

Hello. I've noticed an error in the pinout information on the WIZ-IP20 website: https://docs.wiznet.io/Product/Modules/Serial-to-Ethernet-Module/WIZ-IP20 The pinout in this image is a top view, not a bottom view. Therefore, all the pins are reversed. Pin 10 (P9) is GND, not NC. Also, a minor point, but the default IP address listed in the manual is incorrect. It should be 192.168.11.2, not 192.168.1.88. Thanks.

I also tried the WIZ-IP55, but I suspect its pinout isn't a bottom view either. When wired according to the manual, no current flows at all, and there's no SPI response. Upon disassembling it, I discovered that P11 is GND.
