Introduction:
Using serial console setup users can get access to the serial console of their router. Serial console setup finds its most important use in debricking a router. Moreover, developers may use it to extract useful debug information from their routers.
This short tutorial explains how to setup serial console for Netgear R6200v1.
Identify location of Serial pins on your router:
First open the case of your router. You should be able to find pins for serial communications at the location indicated in Figure1(a).

Verification of the setup:
To verify your setup, start serial client on your PC with proper parameters and then power on your router. As soon as you do this, you will be able to see debug information from the router on your screen. If you do not see anything, check that all the connections have been made properly and if in doubt, reattach the cables. Verify that the Serial Client has the proper parameters for the connection.
