But, can successfully Ping from PC2 to PC3. ![]() Solved: Greeting, Im unable to Ping from PC1 to PC2, which displays 'Request time out' always. Performing a loopback test in the Arduino IDE serial monitor. After entering the PC1 router IP address in the static box, the ping command works properly. Your message should immediately be echoed by the board, and appear in the output field below. If you’re using the Cloud Editor, select Monitor in the sidebar.Įnter a message and click Send.

The Board selector is not available in IDE 1 – use the Tools > Port and Tools > Port menu options instead. If your board is an Arduino Nano, you’ll need to manually select “Arduino Nano”. Wiring diagrams for UNO and Nano can be found in Examples.Ĭonnect the board to your computer and select it with the Board selector. On Mega boards, which have several serial ports, you can use RX0 and TX0. If the Ping fails, it points to a cable or SFP problem. If the router and port ASICs are properly initialized, the interface must come up and self ping must work. This test verfies the packet path inside the router all the way till Physical Layer Interface Module (PLIM). Remove any shield, jumper cables, or other connections to the board.Ĭonnect a jumper cable from the RESET pin to any GND pin.Ĭonnect a jumper cable from the RX pin to the TX pin. Configure the Interface in Local Loopback.
