* Pins 13 and 26 control the NE-4100-ST Debug Serial COM Port’s TXD and RXD signals. The
location of the Debug Serial COM Port is shown on the previous page. This port is not needed
during normal operation. However, if the network fails and you need to configure your NE-4100T,
you may connect the Debug Serial COM Port, and then use the serial console to configure your
NE-4100T.
