- optical isolation of ALL digital signals -> Radio Control, CW, 2xPTT, FSK, PA from USB port Compatible with most standard MS Windows based logging or control software - special microHAM "USB Device Router" program creates as many virtual COM ports as needed for full functionality with your favorite programs...
PTT outputs and works as a CW memory keyer. If computer equiped with Windows OS is connected and "microHAM USB Device Router" program is running, MK works as before plus as an Interface. It transfers all digital and analog signals generated by computer logging program to the transceiver and back.
Run "urouter_release_xx_xx.exe" (xx_xx is version) from CD to start the installation. If a VCP driver of a microHAM USB interface was previously installed, installer will launch "FTDI Uninstaller" before finishing the installation. If you want to keep using VCP drivers of USB interfaces, choose cancel button.
For example, USB interface has a simple page with only several controls that allows to associate the interface with virtual serial port(s). On the other hand, micro Keyer has more complex controls organized in several subpages that allows also to change keyer configuration. Device tab is created when a device is first time detected by router and remains in router even though device is disconnected.

Any changes of these settings on subpages "Audio", "PTT/FSK", "CW/WinKey" are applied immediately to MK. Default settings stored in EEPROM are not altered in this way. It means that if micro Keyer will be next time powered without connection to computer it will use the old settings stored in EEPROM. To change these default settings use button "Store as Default"...

You can select frequency of CW side tone generated by internal speaker. Side tone is generated by main micro KEYER CPU, not by pin.5 of WinKey. This pin is reserved always for the PTT or for second CW output for second radio. (Useful with feature SO2R Extension box).
