The console cable is not within the origin pack. So you have to purchase one or make one by yourself. Or if you are good at electrical, we could share pinout schema for you.

Console Cable Appearance and Pinout

If your PC can't support RS232(COM) port, you would need a converter which can convert RS232 to USB, like the following figure.


  • Console Cable Connection

1. Example of RS232 - RJ45. RJ45 interface is plugged-in to Console port.


2. Example of RS232 - TTL. Note that, for S20 the 4pin interface should be connected to the SYS UART.


3. Example of RS232 - 10 pin. Note that the pinout sequence should be matched on both sides. Watch out the pinout number printed on the device motherboard and the  console cable board.


4. Example of RS232 - 5 pin. Note that the pinout sequence should be matched. Watch out the pinout number printed on the device motherboard.
