Proper assignment of the virtual COM ports is vital for intergration with loggers. Read the following information carefully. USB Interface II has four functions with indication of the state and settings applied by the host application Radio Control (uses RxD and TxD) ● CW (uses DTR) ●... -
Page 14: Cw Port
© 2016 All rights reserved CW PORT By their very nature, USB ports are not well suited to transfer the real time events required for CW keying on virtual serial port control signals (DTR). In addition to the latency in USB, there are also latencies caused by computer CPU load, internal Windows message processing (inter-process communication) and data flow from other peripherals using the USB ports. -
Page 15: Setting Audio Levels
6 - SETTING AUDIO LEVELS There are two trimers on the side panel of USB Interface II for adjusting audio levels. The one closer to front panel adjusts the level of audio signal level from the radio to the computer LINE IN or MICROPHONE input. The one closer to rear panel provides adjustment of the audio signal level from the sound card to the transceiver AF IN. -
Page 16: System Considerations
● 7 - SYSTEM CONSIDERATIONS USB Interface 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 USB Interface II. When used with Windows based contest logging applications like N1MM Logger Plus, Win-Test, and WriteLog or Windows based general logging applications like DXBase, DXLab Suite, DX4Win, Logger 32 and others, the microHAM control and interface application “microHAM Router”... -

© 2016 All rights reserved APPENDIX B – FSK with MMTTY The USB II does not support FSK in the traditional way. However the unit can be used for FSK with the proper software. Each radio specific cable set includes FSK connections which are shared with the CW output. -
Page 22: 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. -
Page 23: Appendix D - Cables And Bridges
© 2016 All rights reserved APPENDIX D – Cables and Bridges Cables are Bridges are an experimental capability – microHAM provides no support or warranty for the Cables and Bridges capability. These features are undocumented but relatively self-explanatory. Cables (cross wired, aka “null modem” cable) create interconnected virtual ports which can be configured as a bus, point to point pair like com0com, or point to multi-point (star, splitter or combiner) - like VSPE.
