Basic RS-232 Control:

ASCII (not decimal) and hexadecimal examples are shown below. The commas in the Hex example are merely for your ease of reading and are not required in transmission. All strings must have a space between each number or letter (except two digit numbers). In the Hex examples the space is already represented with code “20.” The end of each string must have a carriage return after the last number with no space in-between, this is represented by “<CR>” in the ASCII examples and “0D” in the Hex examples.

Tone On	W 1 3 1<CR>	57,20,31,20, 33,20,31,0D
Tone Off	W 1 3 2<CR>	57,20,31,20, 33,20,32,0D
Tone Toggle	W 1 3 3<CR>	57,20,31,20, 33,20,33,0D

Please Note: ”<CR>” stands for Carriage Return and the Hex Code is “0D”.

A space in Hex is “20”, a space in ASCII is just a blank space (as shown above).
