4 - INSTALLATION
Installing microKEYER II consists of several steps:
1) prepare MK II to work with your radios
2) install microHAM USB Device Router (the control and interface software)
3) configure microHAM CODEC
4) configure Router
5) set audio levels
Preparing microKEYER II for Use
1. Turn off the radio and make the rear panel of microKEYER II accessible.
2. Plug the DB37M of the radio cable set into the RADIO connector on the rear panel of the MK II. Connect ALL
connectors from the cable set to the matching jacks on the rear panel of your transceiver.
3. If your transceiver has dual receivers (FT-1000D, FT-1000MP, FT-2000, FT-9000, Orion, IC-7800, K3, etc.)
connect the fixed level audio output from the second receiver to the SUB RX jack
4. Connect the station microphone to the RJ45 MIC jack. If your microphone has a Foster
(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.
WARNING: Microphones with both dynamic and electret elements are not supported. Configure the
MIC (RJ-45) input for either a dynamic or electret element and do not switch types.
5. If you use a second microphone, connect your headset to the EXT MIC jack on the front panel.
Serial Numbers less than 900:
If the headset microphone uses an electret element (e.g. Heil iC or
typical computer headset), open the microKEYER II and move the
DYN-EL jumper located behind the EXT MIC jack to the EL position.
NOTE: an electret element must be connected to both the tip and ring
of the 3.5mm STEREO plug. Heil headsets will require a 3.5mm
mono to stereo adapter.
Serial Numbers greater than than 900:
If the headset or boom microphone uses an Electret microphone with a
STEREO plug (e.g, many computer headsets), open MK II and move
the DYN-EL jumper located behind the EXT MIC jack to the EL
position.
If the headset or boom microphone uses an electret mic with a MONO
plug (e.g., Heil iC elements), open MK II and move the jumper to the iC
position.
WARNING: Headsets with both dynamic and electret elements are not supported. Configure the EXT
MIC for either dynamic or electret element and do not switch types.
6. Connect your paddles to the PADDLE jack.
