4.1. Front Panel Controls and Indicators

• LCD displej: Shows operational information, settings, and decoded CW messages.
• Rotary Encoder (CMD & WPM): Used for navigating menus, adjusting settings, and controlling Words Per Minute (WPM) speed. Pushing down on the encoder typically switches between Command Mode and WPM adjustment.
• Tlačítka M1–M4: Programmable memory buttons for storing and recalling frequently used messages or commands.
• Tlačítko TÓN: Activates a sidetone for monitoring your CW output.
• Tlačítko PTT: Manually controls the Push-To-Talk function for your transceiver.
• Tlačítko TX: Initiates transmission.
• Arduino/Winkey Switch: Selects between Arduino mode and Winkey mode for keyer operation.

• USB (CLI command only): Main USB port for connecting to a computer for configuration, firmware updates, and Command Line Interface (CLI) commands.
• USB HOST: Allows connection of a USB keyboard for direct text input.
• PADDLE: Input for connecting a CW paddle or key.
• PTT: Output for Push-To-Talk control of a transceiver.
• RTS: Output for controlling the transceiver (CW direct by RTS from PC).
• TX: Transmit output.
• TONE IN: Input for CW decode from an audio source.

5. Nastavení

Follow these steps to set up your Walfront K3NG Keyer:

1. Připojení napájení: Connect the provided USB cable to the USB port on the keyer and to a suitable USB power source (e.g., computer USB port, USB wall adapter). The device will power on automatically.
2. Paddle/Key Connection: Connect your CW paddle or straight key to the "PADDLE" input jack on the keyer.
3. Transceiver Connection (Optional):
   • For PTT control, connect the "PTT" output to your transceiver's PTT input.
   • For direct CW control via RTS from a PC, connect the "RTS" output to your transceiver's appropriate input.
   • For transmit output, connect the "TX" output to your transceiver's keying input.
4. Audio Input for Decoder (Optional): To utilize the CW decoder, connect an audio output from your receiver or transceiver to the "TONE IN" jack.
5. USB Keyboard Connection (Optional): If desired, connect a standard USB keyboard to the "USB HOST" port for direct text input.

Once connected, the LCD display will illuminate, indicating the device is ready for operation.

6. Návod k obsluze

The K3NG Keyer offers a wide range of functions. This section covers basic operation.

6.1. Basic Keyer Operation

• Zapnutí: The keyer powers on automatically when connected to a USB power source.
• WPM Adjustment: Rotate the central encoder to adjust the Words Per Minute (WPM) speed. The current WPM will be displayed on the LCD.
• Mode Selection (Arduino/Winkey): Use the small switch near the Arduino/Winkey labels to select the desired operating mode. Refer to the K3NG firmware documentation for detailed differences between these modes.
• Sending CW: Use your connected paddle or key to send Morse code. The keyer will generate the corresponding tones and key your transceiver if connected.

6.2. Pokročilé funkce

• Příkazový režim: Press the rotary encoder to enter Command Mode. In this mode, you can navigate through various settings and functions displayed on the LCD. Rotate the encoder to scroll through options and press to select.
• Paměťová tlačítka (M1-M4): These buttons can be programmed to send pre-recorded messages. To program, typically enter Command Mode, navigate to the memory programming section, and follow the on-screen prompts. To send a stored message, simply press the corresponding M button.
• CW Decoder: When an audio signal containing CW is fed into the "TONE IN" port, the keyer's built-in decoder will attempt to display the decoded text on the LCD.
• USB Keyboard Input: Connect a USB keyboard to the "USB HOST" port. You can then type text directly, and the keyer will convert it to CW and transmit it.
