4 - INSTALLATION

Installing micro2R consists of several steps:

1) prepare micro2R to work with your radios

2) install microHAM USB Device Router (the control and interface software)

3) configure Router

4) set audio levels

Preparing micro2R for Use

1. Make up two cable sets to connect your radios to micro2R.

Schematic index A B X Y

Signal name PTT PTTG MIC MICG

Mobile Icom (RJ45) 4 7 6 5

Desktop Icom (Foster8) 5 6 1 7

Kenwood TS-480 (RJ45) 5 4 3 6

Kenwood & Elecraft (Foster8) 2 8 1 7

Mobile Yaesu (RJ45) 6 7 5 4

Desktop Yaesu, TenTec (Foster8) 6 5 8 7

TenTec (Foster4) 3 4 1 2

2. Turn off both radios and make micro2R rear panel accessible.

3. Connect the cable from your left hand transceiver to the Radio 1 DB9 jack.

4. Connect the cable from your right hand transceiver to the Radio 2 DB9 jack.

5. Connect cables from PTTIN1 to the PTT out of RADIO1

IMPORTANT: This connection is required for proper audio switching in VOX operation.

6. Connect cables from PTTIN2 to the PTT out of RADIO2

IMPORTANT: This connection is required for proper audio switching in VOX operation.

7. Connect your headset to the Mic and Phones jacks.

8. Connect your paddles to the PADDLE jack.

9. If you use a foot switch or hand PTT, connect it to the FOOTSW jack.

10. Connect the SC OUT jack to the Line Out or Speaker jack of your sound card.

11. Connect the SC MIC jack to the Microphone jack of your sound card.

12. Connect a 12V-16V DC supply to the DC 13.8V jack.

Be sure to observe the proper polarity

NOTE: Do not use a power supply that is connected to either radio. Using a common power supply

for micro2R and a transceiver will permit power supply return currents from the transceiver to flow through the micro2R grounds. As a result of design defects in the microphone circuit of nearly every amateur transceiver, the return currents will generate a voltage in series with the microphone input which will result in unwanted feedback (often called "RFI").

13. Locate the USB cable but DO NOT connect it at this time.

Installing microHAM USB Device Router

The Windows setup utility will start and ask into which folder Router and its supporting files should be installed. Note: unless you have a very strong reason to install Router elsewhere, please accept the default location.

To install Router click on the Install USB Device Router link on the installation CD or download the most recent installation package from the web site:

www.microham.com/contents/en-us/d29.html

If you download an updated package, click on "urouter_release_xx_xx.exe" (xx_xx is version) to start the installation.

When the Router installation is completed, click "Finish" to launch Router for the first time. Then plug in the USB cable and proceed to configuring Router for your station and software.

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.

In order to configure and use micro2R with Windows compatible application programs, you must have installed the USB driver, started Router, applied power to micro2R and turned the device on. Router is then configured as required by the application (logging, control or digital mode) software.

micro2R includes an LPT (parallel) input. This connection is required for applications which do not support the microHAM SO2R Control Protocol or provide focus control information on a serial port.

micro2R Status

When the USB driver is installed correctly and micro2R is turned on Router will show a device tab with a GREEN check beside the device name (u2R).

When Router shows a YELLOW “X” instead of a green , it means the USB driver is correctly installed but micro2R is not turned on.

When Router shows a RED “X” instead of a green , it means the device is disconnected and Router does not see the USB part of micro2R. This happens when the USB cable is unplugged or the USB driver is not correctly installed.

Initial Setup

Router must be used to configure micro2R for proper operation. The device configuration tabs (in the red rectangle) are used to setup each part of the micro2R.

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.

In order to use these virtual Ports, you must first create the ports and then assign a port to each function you wish to use (radio control, PTT, CW, FSK, etc.).

DO NOT define a port that is already in use (for example, COM1 or COM2 which are hardware ports on many motherboards) or a virtual port that is used by another USB device. Even though Router will not allow creating a virtual port on a COM port number which is already present in the system (like hardware COM ports or internal modems), sometimes these ports are hidden. If a device which also uses virtual serial ports (external USB devices, bluetooth devices, mobile phones, PDAs etc.) is not connected to the computer when creating virtual ports in Router, the ports can overlap and will not work properly when you connect such device.

WARNING: Before you begin to create virtual ports, attach all external devices you are using with

computer and allow them to connected to the system. Restart Router and then create virtual ports.

Virtual ports are created on the Virtual Port menu.

Create - Creates virtual COM ports. It is possible to select more than one port at a time by holding the Ctrl key on keyboard and clicking on COM port numbers. Creating virtual ports may take a long time (several tens of seconds), be patient.

Delete - Deletes any single virtual port. Delete All - Deletes all previously created virtual

ports. Do not delete a virtual port until all applications using

that port have been closed.

TIP: It is possible to select multiple ports at one time by holding the Control key on keyboard and clicking on the COM port numbers.

TIP: If you have removed another device which used virtual ports and Router does not offer the released COM port number, you will need to reset the virtual port bus. You can do this by deleting all virtual ports in Router at once. Select "Virtual Port | Delete All" then create the ports again. Any missing COM port numbers should appear.

5. microHAM USB DEVICE ROUTER

ROUTER MENU

Default Router Settings: used to completely reset Router to factory (default) settings.

"Default" removes all device tabs and deletes all stored configuration data, including all user presets from the Windows Registry.

TIP: The micro2R can be completely reset by selecting Default Router Settings followed by Device | Store as Power-up Settings to save the defaults to the controller's EEPROM.

Restore Router Settings: used to restore settings from a urs file created by the backup command.

A urs file can be used only with the device for which it was generated (the file contains the unit serial number) on a computer with same port assignments.

WARNING: Restoring a backup deletes all current Router settings including presets, use it carefully!

Backup Router Settings: used to create backup urs file.

This file contains Router settings (including Presets) for all devices defined in Router.

Options | General

Load Router on Start-up: when checked, Router will start automatically each time the computer is

started or rebooted.

Start Router Minimized: when checked, Router will started minimized

Options | Band Map: Customizable band edge boundaries used to drive the band data output. BCD codes can

be customized for driving antenna switches or bandpass filter control.

Options | Digital Band Map: (Not used with micro2R)

Customizable band boundaries for the digital mode operation. This setting is used to automatically select VOICE or DIGITAL audio switching and the proper PTT output. Careful selection of the "Digital band" is necessary for transceivers which do not have a special mode for AFSK operation or do not report the mode in the computer command set. This primarily effects Kenwood and TenTec transceivers although it applies to some older Icom and Yaesu radios.

Options | Audio Devices:

Don't use audio devices: when checked, Router does not use audio devices and the settings on the

Audio Mixer and DVK tabs have no effect.

WARNING: When selected, Router will not be able to control micro2R Audio Mixer and DVK, use it carefully!

Manually assign audio devices: when checked, Router will allow the user to select audio devices

(sound card) in the appropriate fields of the Audio Mixer tab and will actively control the audio devices

Automatically assign microHAM audio devices: (Not used with micro2R)

when checked, 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.

Options | DVK:

Voice message time limit: maximum time for each voice message up to 120 seconds. Sample rate: sampling frequency used during recording and playback of voice messages. Sample size: sampling size used during recording of voice messages. Sampling size primarily effects

audio quality of the messages. 16bit samples provide higher quality than 8bit.

NOTE: Select the same sample rate and size as used by your software to avoid message distortion.

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.

Minimize: Clicking this will minimize Router to the system tray

at the bottom right corner of the Windows Task Bar (the "System Notification Area").

TIP: When Router is minimized you can restore it by double-clicking on the Router tray icon. You can also restore Router by double-clicking on the Router icon on the desktop or in the Programs menu.

Exit: Clicking on this item will terminate Router.

NOTE: when Router is terminated the virtual ports will be closed and application software will be unable

to communicate with micro2R and the radio.

PRESET MENU

The requirements of each application (logging, control and digital mode programs) are different. Each program handles radio control, CW, FSK, PTT, and the sound card its own way. In some cases, what works for one application may not work properly with another. To get maximum performance from micro2R, the user should create customized settings for each application used.

For easy switching among applications, Router supports up to 12 user definable Presets. Different configurations can be stored in these presets and recalled almost instantly simply by clicking on the preset button.

Each preset contains the settings for all devices connected to, and controlled by, Router. For example, if Router controls a microKEYER II, a USB Interface II and Station Master, each preset remembers the settings for all devices including the assignment of COM ports and the contents of all sub-tabs except the FSK/CW Messages and DVK tabs.

NOTE: Presets are not available until they have been created and saved

by the user using Preset | Save as. For sample configurations for popular software, refer to the Setup Guide documents available in Router Help menu. Use Help | Download Documents if the Setup Guides are not available or incomplete.

There are three ways to apply a preset once it is created:

Click on Preset and select from the pull-down menu.

Click on a preset button. For the buttons to be visible in Router, Preset | Show Buttons must be checked. When the settings from a preset are applied, a green light located in the preset button is lit. This green light is on ONLY when all settings in Router are same as those stored in the preset.

By right clicking on the system tray icon when the Router is minimized.

The presets and the current router configuration are stored to the registry when Router is closed and recalled when Router is loaded.

Save as - Saves the current Router settings to a preset for future use. Rename - Allows renaming of an existing preset. Delete - Delete chosen preset. Show buttons - When checked, Router shows the preset buttons.

DEVICE MENU

Router can control several devices. This allows configuring the settings for all (interfaces) connected to the computer at the same time using the Presets.

Each device has its own tab (page) in the main Router notebook. The content of each device tab depends on the type of device. Adding a device is automatic when Router detects a new device. Once detected, a device remains in Router even though device is disconnected. 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.

Rename – Creates a custom device name. This is useful if two

or more devices are connected to the Router. For example CW KEYER and microKEYER II can be renamed to more identifiable names as shown here...

Delete - Removes a device from the Router. Only

disconnected devices with a RED “X” on device tab can be removed. To disconnect a device from Router, unplug the USB cable from the computer or device.

Save Template - will save the current Router settings to template file.

When clicked, Router will open a standard File Save dialog window – the default location is C:\Documents and Settings\All Users\Application Data\microHAM\cfg. If a hypertext (html) or plain text (txt) documentation file of the same name as the template is present in the same directory, it will be associated with the template.

Load Template – will automatically configure Router from a template (*.tpl file).

When clicked, Router will open a standard File dialog – the default location is: C:\Documents and Settings\All Users\Application Data\microHAM\cfg - and the desired template can be chosen. When Router loads a template, it looks for an html or txt file with the same name as the template in the same directory. If such file is found, it is displayed.

TIP: Templates are a powerful tool for quickly configuring Router to work with a particular application. Template files are interchangeable between computers and ideal for cloning setups in multi-computer stations or for sharing configurations between users.

Store as Power-Up Settings: - will store the current settings of the Audio Switching, PTT, CW/WinKey,

SO2R and ACC tab to the micro2R EEPROM. If micro2R is operated without connection to the computer it will use the settings stored in EEPROM. If micro2R is connected to a computer running 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

To update firmware, download the firmware file to your computer, then click on Device | Upload Firmware. A Windows file dialog will open, navigate to the directory into which you downloaded the firmware file and select the file.

NOTE: If you upgrade Router, each upgrade will include the latest firmware file. The new firmware

will be automatically uploaded to the micro2R when the new version of Router connects for the first time, you have just to confirm the upgrade when prompted.

VIRTUAL PORT MENU

It is necessary to create a number of virtual serial ports (COM ports) in order for a Windows application (logging, control or digital mode program) to access microHAM devices.

Create - Creates virtual COM ports. It is possible to select more ports at once by holding the Control key on the keyboard and clicking on COM port numbers. Creating a virtual port may take a while, be patient.

Delete - Deletes any single virtual port. Delete All - Deletes all previously created virtual

ports and resets Virtual Serial Port bus. Do not delete a virtual port unless all applications

using that port have been closed.

NOTE: Properly working ports should not display an exclamation mark (!).

HELP MENU

Manuals: Link to microHAM manuals located on your system Setup Guides: Link to software configuration guides for many common applications. Cable Schematics: Link to cable diagrams. Download Documents: Downloads microHAM documentation including updated manuals and setup

guides. You may specify the products for which you want documentation. This requires an Internet connection.

microHAM Home Page: Link to www.microHAM.com microHAM Downloads Page: Link to www.microham.com/contents/en-us/d29.html Show Tooltips: When checked, small, single line help is displayed below the mouse cursor Update Router: Download and install the most recent version of Router. About: Shows the Router's internal version number Change logs: Shows the Router and firmware changes.

DEVICE CONFIGURATION TABS

There are ten (10) tabs for configuring micro2R. Each tab controls part of micro2R's functions. Except for CW Messages, FSK Messages and Functions tabs, any change is applied immediately to micro2R.

●

Ports: assign virtual ports to the micro2R for use by applications

●

Audio: configures headphone switching based on operator preference, receive focus and transmit source.

●

Audio Mixer: sets sound card levels.

NOTE: The Audio Mixer is not available under Vista or Windows 7. Those operating systems do not

permit an application like Router overall control of the sound device.

●

PTT & ACC: configures T/R keying and foot switch functions

●

CW/WinKey: configures the internal CW keyer

●

CW Messages: enter/store internal CW message memories

●

FSK Messages: enter/store internal FSK message memories

●

DVK: configure and control the level of Router's voice keyer

●

Keyboard: configure operation of PS/2 keyboard or keypad

●

SO2R: select source of focus control and other SO2R operating features.

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.

Proper port configuration is critical for operation with application software.

micro2R has eight channels – each channel provides an indication of the settings applied by the application and current state (e.g., or or off).

These eight channels (functions) are available for each radio:

●

FSK (uses TxD for FSK and RTS for PTT if checked)

●

2nd FSK (uses TxD for FSK and RTS for PTT if checked)

●

CW (uses DTR or RTS)

●

PTT (uses DTR or RTS)

●

2nd PTT (uses DTR or RTS)

These channels are common to both radios.

●

WinKeyer2 (uses RxD and TxD)

●

Control (uses RxD and TxD)

●

Foot Switch (uses CTS, DCD, DSR or RING)

NOTE: Do not assign virtual ports for the channels/functions which are not used by your

applications. It is unnecessary and only consumes resources.
