NOTE
1) 15-meter communication cable is suitable for less interference
environment. If the transmission speed is over 38400bps, the
length of communication cable should be shorter than 3 meters
so as to ensure the accuracy of transmission.
2) Numbers shown in the above diagram represent the pin number
