DTMF COMMAND INPUT
Dual Tone Multi Frequency (DTMF) is typically used in the telephone system for dialing. The RI-300 uses DTMF as the
primary means for the owner and users to control and communicate with the repeater. DTMF is made up of eight tones with
two of the eight turned on in each of the sixteen keystrokes. DTMF is used because of the reliability and ease of use in the
audio transmission range. When sending commands to the controller, you must send each DTMF digit with a delay of 3.5
seconds or less between digits. Then un-key the transmitter. This action is the same as the "enter" key on your computer
keyboard. If the squelch is open or not properly set, the controller will not be able to detect the un-key action. In this case you
can wait for the inter-digit timer to expire, at which time the controller will attempt to process the command. Once the
command is sent, the controller will respond with one of three actions.
1. CW “OK” is a result of a successful command.
2. Speech “ERROR” is a result of an error in the data of a S-Command or macro.
3. No response, the controller did not receive the command or the command was not valid.
