Page 13: Configuring Microham Usb Device Router
The microHAM USB Device Router (Router) program provides a Windows compatible configuration tool for microHAM USB Devices (micro2R as well as DIGI KEYER, microKEYER II, CW Keyer and USB Interfaces) and software interface to other Windows applications (logging software, digital mode software, etc.). The software interface is provided as Virtual Serial Ports. -
Page 14: Creating And Using Virtual Serial Ports
© 2010 All rights reserved Creating and Using Virtual Serial Ports microHAM Router provides a set of virtual serial ports which allow Windows applications (logging and digital software) to work with micro2R just as they would work with "real" (hardware) serial ports. -
Page 15: Microham Device Router
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. This setting does not apply to micro2R, it applies only to DIGI Keyer. -
Page 16: Menu: Preset
© 2010 All rights reserved Options | USB: Noise immunity: selects how many times an undelivered USB packet will be repeated before the USB device is disconnected from the operating system. Response time: selects how long the USB interface will wait for additional data before sending data to the operating system. -
Page 17: Menu: Device
Each device is identified by a unique serial string. NOTE: Router supports all microHAM USB devices in a single instance by creating a separate root tab for each device. It is not necessary to run multiple instances of Router; a secondary instance can not be started. -
Page 18: Menu: Virtual Port
Router, the Router settings will be used but the default settings are retained in EEPROM. Upload Firmware: microHAM will occasionally release updates to the firmware in micro2R. The update may support new features in Router or improve application compatibility. The most recent public version of the firmware is always available from www.microham.com/contents/en-us/d29.html... -

Page 20: Ports Tab
© 2010 All rights reserved PORTS TAB Once the virtual ports have been created they must be associated with a specific function or device channel (e.g., Control, CW, PTT, etc.). These assignments should correspond to settings of the application software and must be configured first in Router then in the application. -
Page 21: Fsk & 2
© 2010 All rights reserved FSK & 2 FSK PORTS The FSK channel is used by the application program to send the FSK keying signal. FSK is used primarily for RTTY. It is very important to understand the difference between FSK and AFSK. -

DTR/RTS except that the output is inhibited for one second after the COM port is opened. RTS*/DTR* should only be used with programs that cause unwanted key-ups during startup. NOTE: the CAT port may be used for CW if is provided by a microHAM interface. TIP: More applications use DTR for CW than RTS. -

PTT – for example, a logging program and CW reader/keyboard. NOTE: the CAT port may be used PTT if it is provided by a microHAM interface. TIP: Always use serial PTT instead of the radio command PTT or VOX. It is the only way to assure proper sequencing of a Power Amplifier, LNA or receive antenna switch. -
Page 24: Ports: Ptt & 2 Ports: Winkeyer2
© 2010 All rights reserved WinKeyer2 WinKeyer2 is the next generation of the unique external CW processor developed by Steve Elliott, K1EL: WinKey with integrated dual radio support. This CW processor supports paddle input like any other electronic keyer, is highly configurable, and converts input received in ACSII (text) format to Morse characters. -
Page 25: Ports: Control
The Control Port allows an application program (logger) that implements the microHAM Control (SO2R) Protocol to operate micro2R completely with only a single USB connection. The microHAM SO2R Control protocol allows a logger to specify Transmit Focus, Receive Focus, Stereo/Split headphone as well as control antenna switching and optionally use the CW, FSK and voice memory functions. -

Page 55: Appendix B - Microham Control Protocol
APPENDIX B – microHAM Control Protocol Introduction This appendix describes the commands in the microHAM Control Protocol that are likely to be useful to users in creating custom macros in loggers that support user defined “scenarios.” These user level commands can be used to select antenna outputs (e.g., the 4 bit value on pins 6-9 (Radio 1) and 10-13 (Radio 2) of the Accessory port), to select transmitter or receiver focus, or to control the Digital Voice Keyer, CW Memory Keyer or FSK Message memories. - Page 56 © 2010 All rights reserved Abort: This command aborts the current message and clears message queue.

Page 57: Appendix C - Rfi Considerations
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. -
