Despite product title, this is not an "Ethernet Converter", is it? It just uses ethernet cable?

Hi, DB9 to RJ45 adapter is used to process serial data communication between RS232 port devices over an inexpensive Ethernet cable, not to process Ethernet connection for internet signal.

Is the listed pinout correct for this product?

Hello, this 9 pin to ethernet adapter's pinout is 1-1, 2-2, 3-3, 4-4, 5-5, 6-6, 7-7, 8-8, 9-x (straight through connector, please check the updated pinout picture)

Can this be used with a USB-to-RJ45 console/rollover cable to connect to DB9 console porton a switch or router?

Hi, this straight through DB9 to RJ45 connector should work for your situation. If not, please feel free to contact us via the order page's "contact seller" for a return.

are these crossover (null modem) connectors or straight through?

Hi, these are straight through DB9 to RJ45 connectors.
