Connecting to the transmitter

Arduino Serial Monitor settings

• Autoscroll
• Line ending: Carriage return
• 2400 baud, 8 bits, No parity

Switching to command mode

1. connect the Arduino's USB port to your computer
2. run the Serial Monitor, or any other serial comm program using the settings above.
3. close the Mode switch to select the Command mode

841 bytes is the EEPROM usage (1024 max).
The "1>" is the command prompt.
The figure 1 before the ">" is the current model. There are 9 models, each one contains the settings for a distinct model.

EEPROM Error message
When you run the software for the very first time, it detects that the EEPROM is not properly initialized.
The buzzer and the LED play the EEPROM alarm code and the Serial Monitor displays "EEPROM error".
Then you must initialize the EEPROM.

Connecting to the transmitter with "screen" under Linux
The "screen" command is available in many distributions.

1. In the Arduino menu bar, open Tools / Serial Port to find the name of your serial device, for instance: /dev/ttyUSB0
2. Open a Terminal window and enter at the "$" prompt: screen -L /dev/ttyUSB0 2400
   Notice: the -L option enables session logging: everything is copied into a "screenlog" file in your working directory.
3. Press the Enter key a few times and the Arduino should display its command prompt: "1>"
4. If you make a typing mistake, you can cancel your input by pressing the Escape key

Reminder: Type Ctrl-A K to exit "screen".

Connecting to the transmitter with "putty" under Windows
Install the "putty" application from www.putty.org

1. In the Arduino menu bar, open Tools / Serial Port to find the name of your serial device, for instance: COM1
2. Start putty and configure it: in the right pane, click the "Serial" option in "Connection type", then enter COM1 in "Serial line" and 2400 in "Speed".
3. Click the Logging item in the left pane, then click "All session output" on the right, to have everything copied into a "putty.log" file.
4. Save these settings for later use.
5. Click the "Open" button and press the Enter key a few times and the Arduino should display its command prompt: "1>"
6. If you make a typing mistake, you can cancel your input by pressing the Escape key
