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