    The software interface is provided as Virtual Serial Ports. In order to configure and use microKEYER II with Windows compatible application programs, you must be running Router and have turned on microKEYER II. Router is then configured as required by the application (logging, control or digital mode) software.

  • Page 13: Creating And Using Virtual Serial Ports

    Router provides a set of virtual serial ports which allow Windows applications (logging and digital software) to work with microKEYER II just as they would work with "real" (hardware) serial ports. In order to use these virtual Ports, you must first create the ports and then assign a port to each function you wish to use (radio control, PTT, CW, FSK, etc.).

    "Default" removes all device tabs and deletes all stored configuration data, including all user presets. from the Windows Registry. TIP: microKEYER II can be reset to the factory configuration by selecting Default Router Settings followed by Device | Store as Power-up Settings to save the defaults to the keyer's memory.

  • Page 15: Menu: Preset

    Each preset contains the settings for all devices connected to, and controlled by, Router. For example, if Router controls a microKEYER II, a USB Interface II and Station Master, each preset remembers the settings for all devices including the assignment of COM ports and the contents of all sub-tabs except the FSK/CW Messages and DVK tabs.

    © 2010 All rights reserved CAT PORT & 2 CAT PORT The CAT channel is used by the application software to control transceiver frequency, mode, T/R switching and many other parameters. The application communicates with the radio using a serial protocol. Although most modern radios implement some form of serial control, nearly every radio implementation is different.
  • Page 22 Tracking: This function allows an external receiver to track the transceiver attached to the microKEYER II. NOTE: The transceiver attached to microKEYER II must be properly interfaced and CAT must be functioning properly. Tracking does not work for “no radio” choices.

  • Page 24: Fsk & 2

    © 2010 All rights reserved FSK & 2 FSK PORTS The FSK channels are used by application programs to send the FSK keying signal. FSK is used primarily for RTTY. It is very important to understand the difference between FSK and AFSK.

  • Page 25: Ports: Cat & 2 Ports: Fsk & 2 Ports: Cw

    © 2010 All rights reserved Strict bps: Some programs rely on the the UART "buffer full" signal for proper PTT timing and drop PTT (unkey) when the UART buffer is empty. Because virtual ports generally have two buffers - one in the USB driver and one in the hardware - the first buffer may empty before all of the data has been transmitted allowing the PTT to before the message is complete.

  • Page 26: Ptt & 2

    © 2010 All rights reserved PTT & 2 PTT PORTS The PTT channels are used to control transmit/receive switching of the transceiver and power amplifier. An internal sequencer assures 100% protection against hot switching of the PA when the PTT channel is used.

  • Page 27: Ports: Winkey

    © 2010 All rights reserved WinKey PORT WinKey is a unique external CW processor developed by Steve Elliot, K1EL. This CW processor supports paddle input like any other electronic keyer, offers many configuration options, and in addition converts ASCII data from the computer to Morse characters. This unique property assures perfectly timed CW output from the computer regardless of OS load.

    If a line ends in three dots (...) it means that the command or response has been broken across two USB packets. CONTROL PORT The Control Port allows an application program (logger) that implements the microHAM Control Protocol to make use of the microKEYER II CW, FSK and DVK message memories When an application opens the control port, Router reports port as open and displays settings used to configure COM port.

  • Page 29: Audio Switching Tab

    © 2010 All rights reserved AUDIO SWITCHING TAB microKEYER II uses an advanced, custom USB audio subsystem which allows Router to handle all of the audio routing. Microphone and receive audio are always connected to microHAM CODEC (the microKEYER II “sound card”).

  • Page 32: Audio Mixer Tab

    If Stereo is not selected, the Audio Mixer tab will display a single set of controls and will mute the right channel. microKEYER II uses the left channel for all output but in some cases you may want to use the right channel for another purpose (for example, when used with the microHAM micro2R - u2R).

Test Signal: causes microKEYER II to output a 1500 Hz audio tone for setting the transmit output level. TX Mixer: this button opens the Windows Volume Control (Playback Mixer) for the selected sound card.
  • Page 34 Note, the display is active only if a sample rate is selected. microKEYER II shows one slider for each input – Left for the Main RX and Right for the Sub RX. Keep the sliders at about 80% and use the RX Main and RX Sub pots on the front panel for adjustment.

  • Page 35: Ptt Tab

    ● PTT OUTPUTS microKEYER II has four PTT outputs: PTT1, PTT2, PA PTT and LNA PTT. PTT1 and PTT2 are brought out to the DB37 Radio connector. PAPTT and LNAPTT are RCA jacks for connecting to external devices. PTT1 is wired to the radio microphone jack and is generally used for CW and VOICE modes.
  • Page 36 © 2010 All rights reserved Router groups operating modes into three classes: CW, Voice (USB, LSB, AM and FM) and FSK/DIGITAL. The available PTT options are: PTT1 (microphone jack), QSK (no transceiver PTT, PA PTT and LNA PTT include only PA/LNA PTT tail) Semi Break-in (no transceiver PTT, PA PTT and LNA PTT include PTT tail and PA/LNA PTT tail) PTT2 (rear panel jack).
  • Page 37 © 2010 All rights reserved FOOTSWITCH SEQUENCER Additional functions can be associated with the footswitch (or hand mic PTT). microKEYER II recognizes when the footswitch is closed (pressed) or open (released) and can manipulate CW, FSK, PTT and audio routing when the footswitch is closed or opened.

    It is absolutely important to prevent ground currents from flowing to the common ground point by way of the signal cable. If you use a microHAM "keyer," a good test is to remove the DB15/DB37 connector and USB cable from the keyer and measure the resistance from the shell of the DB15/DB37 to the shell of the USB cable.
