Setup guide

For Windows 2000 or Windows XP. right click on the Speaker Icon on the task bar and select "Adjust
Audio Properties" or open "Sounds and Audio Devices" in Control Panel and reset the Default device
for Sound Playback and Sound Recording to your computer's primary sound device.
For Windows Vista, right click on the Speaker Icon on the task bar and select "Playback Devices or
open Sounds in Control Panel and reset the Default Playback device to your computer's primary
sound device.
Q. I'm missing some virtual serial ports, can't select them, can;t create them
A. First try to delete all virtual ports from within router and create them again.
If this does not help remove all virtual ports from within Windows (System from within the
Configuration screen), after deleting all ports they will be automatically created again (and hopefully
also the lost ones). It worked here..
Q. Do I have the Realtek sound card driver problem?
A. Select "microHAM CODEC" in the Audio Mixer tab and click, "Get ID". If Wave IN ID <> Wave Out
ID <> Mixer ID (ie. they do not have all the same number) you have the "Realtek problem" where the
application is using the Mixer ID instead of the WAVE IN ID to select audio input.
Q. Using CAT and 2nd CAT ports
A. As two programs CAN NOT under any circumstances look at the same port simultaneously. That is
the reason for the CAT and 2nd CAT ports in Router ... the primary logging/control program looks at
the CAT port to control the radio and the secondary program (e.g., CW Skimmer, Spectravue,
PowerSDR, etc.) looks at the 2nd CAT port for Icom "transceive" broadcasts, Kenwood IF data or
slow speed (< 500 msec) polling with older Yaesu rigs to get the operating frequency for
synchronization.
Q. Where are router's settings and presets stored?
Router's settings and presets are stored in the Windows registry. The stored settings are updated
when Router is closed. Any "registry protection" or "registry backup/restore" program will prevent
saving the settings (by restoring the previous state). In addition, if Router does not close properly, the
settings will not be saved.
Q. How works the virtual serial ports
A. The Eltima virtual serial port is a software interface e.g., it provides software equivalents to the
various buffers and registers of an 8250 compatible UART − for OEM specific hardware and software.
For Router, the Eltima VSP code provides an interface compatible with the Microsoft Communications
Toolbox. The data to/from the foreign applications is transferred to Router which reformats it into a
microHAM proprietary multiplexed data stream (Radio_1 CAT, Radio_2 CAT, Control − which
includes the various PTT, Footswitch, audio routing, and PC generated CW flags − and WinKey
channels) and sends it via a DLL interface at 230Kbps through the USB port and the FTDI UART in
the interface to the microcontroller in the specific interface.
The microcontroller then demultiplexes the data and distributes it to the appropriate process in the
controller. CAT and WinKey data is put in standard ASCII form and handled by UARTS in the
controller. The various control flags are acted on by the firmware to generate the necessary internal or
external controls.
If Router and the microHAM interface are not running, the VSP should either not exist (Router not
running) or return an error (interface not running).
Virtual ports created and defined by Router can only be used to communicate with or control devices
that are attached to a microHAM interface. Just as with a "real" port, only one program at a time may
open a virtual serial port and no two ports (virtual or real) may have the same address (COM
number).
Q. MK2R+ and Vista
MK2R+ works with Vista. However, since Vista no longer allows an application (Router) to control the
audio endpoints, it is more difficult to set−up. In effect, the user needs to use the Vista Volume Mixer
to select each device/endpoint and set the level of that endpoint for each individual application (e.g.,
separate settings for Writelog, N1MM, WinTest, DX4Win, MMTTY, DXLab Suite, etc.).
