3. IMPORTANT WARNINGS
NEVER FORGET !!!
If you plan to use micro KEYER with more than one and not identical
transceivers ALWAYS change original microphone plugged to the micro
KEYER RJ45 jack BEFORE changing DB37 RADIO cable
If you power micro KEYER from external power supplyALWAYS check polarity
of the external 13.8 V supply

4. QUICK START
wInsert CR-ROMto the CD drive
wRun "urouter_release_xx_xx.exe" (xx_xx is version) from CD to start the installation and launch Router.
wConnect USB cable to the micro KEYER. Other cables left unconnected
wPlugsecond end ofthe USB cable to the computer USB port and install USB driver from location:
C:\Program Files\microHAM\driver\d2xx
wYou should see tab with micro KEYER statement with yellowX mark
wPlugaudio cables to the sound card and to the micro KEYER rear panel jacks. Computer Line Out to
micro KEYER Line Out, computer Line In to MK Line In and computer Mic In to MK Mic In.
wTurn OFF your radio
wPlugDB37 radio cable to the micro KEYER and other ends ofthe radio cable to the appropriate radio
jacks.
wTurn radio ON.
wWithin three second you should see single flash ofgreen FSK Led at the MK front panel and a few
seconds you should see Green OK markat Router software next micro KEYER statement tab.
wCongratulation ! You can start playingwith micro KEYER, but better read this manual now:-)

8. PRINCIPLE OF OPERATION
micro KEYER ("MK") is a all mode interface between computer and transceiver.
Computer sound card is connected to MK usingthree (3) standard audio cables and USB port USB A-B
cable. All these cables are included to the MK pack.
Transceiver and MK is connected bysingle radio cable terminated on one side byDB37Mand on the other
side byvarious plugs dependingon the transceiver model. Cable carrypower for MK and all interfaced
signals includingaudio, computer CAT port and all kinds ofkeying. An independent cable comingfrom the
DB37 connects the transceiver front panel microphone jackand MK.
The remainingconnectors at the rear panel ofthe MK are dedicated for external accessories as footswitch,
paddle, microphone ...
MK works in two modes - with computer or without computer. Switchingbetween these modes is
automatical.
Ifcomputer is not connected or not running, MK works usingthe "default" settings. Those settingcan be
customized. In this mode MK provide PTT sequencer controlled byfootswitch or hand mic PTT, drive all
PTT outputs and works as a CWmemorykeyer.
Ifcomputer equiped with Windows OS is connected and "microHAMUSB Device Router" program is
running, MK works as before plus as an Interface. It transfers all digital and analogsignals generated by
computer loggingprogram to the transceiver and back. Compatibilitywith loggingsoftwares is ensured by
usingvirtual serial ports created byRouter program. Router continuouslymonitors these virtual ports, logs
everyevent on them and transfers all these events via USB to the MK. MK is parsingthese data and
resends them to the physical ports oftransceiver as CAT, FSK, CW, and vice versa.

9. PANEL DESCRIPTION
All connectors for connectingcomputer, radio and accessories are situated on the rear panel ofMK.
Rear Panel
(1) - RADIO
DB37F connector for radio interconnections. Detailed description you can find at AppendixA
(2) - RE/SS
Output keyingmode switch for PA output.
RE - Relaycontact
SS - Transistor collector
Ifthe slide switch is in SS position, open collector ofthe switching
transistor is wired to the PAPTT output jack. Transistor can switch load
max. 48V/1.5A. This position is dedicated for all modern Power
Amplifiers with electronic keying. Checkmanual ofyour PA if
groundingofkeyinput will switch PA to the TX state. Checkalso
power ratingofthis input ifit does not exceed transistor rating.
Otherwise move slider switch to the RE position. This position
hardwires relaycontact to the PA PTT RCA with rating max.
125VAC/2A 60VDC/2A.
(3) - PAPTT
PTT output for Power Amplifier. Output depends on RE/SS switch position.
RCA jack
TIP - Signal
SHELL - GND
(4) - REMOTE
MiniDIN6 for PS/2 keyboard or PS/2 keypad.
Second function ofthis connector is to provide an interface for future SO2R Extension box.
