(round) connector, use the adapter supplied with the cable set. If the station microphone uses an electret element (most Icom radios), open microKEYER II and place the Electret jumper located just in front of the three trimmers in the center of the board on both pins.
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.
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.).
(sound card) in the appropriate fields at Audio Mixer tab and will actively control the audio devices Automatically assign microHAM audio devices: when checked, Router will automatically assign proper audio device of the same name if multiple microHAM interfaces of the same kind are connected to the one computer. Options | DVK: Voice message time limit: maximum time for each voice message up to 120 seconds.
FSK, PTT, and the sound card its own way. In some cases, what works for one application may not work properly with another. To get maximum performance from microKEYER II, the user should create customized settings for each application used.
When clicked, Router will open a standard File dialog – the default location is: C:\Documents and Settings\All Users\Application Data\microHAM\cfg - and the desired template can be chosen. When Router loads a template, it looks for an html or txt file with the same name as the template in the...
Keyboard, Display and System tabs to the microKEYER II's EEPROM. If microKEYER II is operated without connection to the computer it will use the settings stored in EEPROM. If microKEYER II is connected to a computer running Router, the power-up settings will be overridden by the Router settings but the default settings are retained in EEPROM.
About: Shows the Router's internal version number DEVICE CONFIGURATION TABS There are eleven (11) tabs for configuring microKEYER II. Each tab controls part of microKEYER II's functions. Except for CW Messages and FSK Messages, any change is applied immediately. Ports: assign virtual ports to the microKEYER II for use by applications ●...
Router then in the application. Correct port assignment is critical for proper operation with application software. microKEYER II has 11 channels – each channel provides an indication of the settings applied by the application and current state (e.g., or or off): CAT (uses RxD and TxD) ●...
CAT is not reliable because RFI can prevent the radio from switching back to receive. In addition, microKEYER II cannot control an amplifier when the application uses PTT by CAT since it has no way to sense that the the application has placed the transceiver into transmit. There is a dedicated T/R switching channel for this purpose called PTT.
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 microKEYER II's 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.

The black box will show the selected microphone. Transmit Monitor: microKEYER II includes a monitor ampflier that provides 2 watts to a user supplied speaker. Router will select the audio source to be monitored based on the operating mode. The monitor level can be set independently for each source/mode.
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.

MASTER only if necessary to keep the WAVE control from operating at one end of its range. Test Signal: causes microKEYER II to output a 1500 Hz audio tone for setting the transmit output level for AFSK digital modes.

Note, the display is active only if a sample rate is selected. microKEYER II shows one sliders 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.
● PTT OUTPUTS microKEYER II has four PTT outputs: PTT1, PTT2, PAPTT and LNA PTT. PTT1 and PTT2 are brought out to the DB37 Radio connector. PAPTT and LNA PTT are RCA jacks for connecting to external devices. PTT1 is wired to the radio microphone jack and is generally used for VOICE modes.

ALC zone (the same level as steps 9 and 11). 7 - System Considerations microKEYER II can be used with a wide variety of software. The capabilities of those packages will have large influence on the level of computing power needed to utilize microKEYER II.
NOTE: The keyboard/Keypad must be PS/2. A USB device with PS/2 adapter will not work properly. microKEYER II includes the ability to generate FSK or CW, record and play CW, FSK or VOICE messages using a PS/2 keyboard or numeric keypad connected to the PS/2 jack. A numeric key pad is sufficient to record and play CW and DVK messages, control CW speed (WPM) or play a serial number message.
SLOVAKIA 11 - WARRANTY microHAM warrants microKEYER II for three (3) years. The product must not be modified in any way except configuration, or the warranty is voided. The warranty does not cover damage caused by improper or abnormal use, failure to follow instructions, improper installation, lightning, or excessive voltage. The product will be either repaired or replaced, at our discretion.
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.
