The earliest Morse code was dots and dashes representing numbers. Numbers correspond to words. You need to look up a code table to know the numbers corresponding to each word. You can click, stroke and pause with the electric keys. Although Morse invented the telegraph, he lacked relevant professional knowledge.

1，point (): 1

2. Cross (-): 1 1 1

3. Pause within character (between dot and dash): 0

4. Pause between characters: 000

5. Pause between words: 0000000

Extended data

As an almost extinct code, American Morse Code uses different dots, dashes and unique intervals to represent numbers, characters and special symbols. This Morse code is mainly designed for ground telegraphers, and it is transmitted by telegraph wires, not by radio waves.

This ancient and staggered code is designed to match the operator's response mode. Unlike now, you can hear the tone of the code from speakers or headphones. You can only hear the click sound from a mechanical generator of these earliest telegrams, and even hear the answer from the send key: this key is set to passive mode when not sending signals, and is responsible for making sounds.

Most of these operators serve railways or future Western Union transmission. Like many young people at that time, Edison in his teens was such an operator.
