2 - IMPORTANT WARNINGS

ALWAYS check the polarity of the 13.8 V power supply.

If you use micro KEYER II with more than one transceiver,

ALWAYS be sure the proper microphone is connected to the RJ45 jack

BEFORE connecting the RADIO interface cable.

If your radio includes upgradeable firmware

DO NOT perform any upgrade through micro KEYER II .

Remember, under Windows, micro HAM USB Device Router must be running

anytime the interface is used (not just for setup). If Router is not running, the

virtual COM ports will disappear and the device cannot be accessed!

4 - INSTALLATION

Installing microKEYER II consists of several steps:

1) prepare MK II to work with your radios

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

3) configure microHAM CODEC

4) configure Router

5) set audio levels

Preparing microKEYER II for Use

1. Turn off the radio and make the rear panel of microKEYER II accessible.

2. Plug the DB37M of the radio cable set into the RADIO connector on the rear panel of the MK II. Connect ALL

connectors from the cable set to the matching jacks on the rear panel of your transceiver.

3. If your transceiver has dual receivers (FT-1000D, FT-1000MP, FT-2000, FT-9000, Orion, IC-7800, K3, etc.) connect the fixed level audio output from the second receiver to the SUB RX jack

4. Connect the station microphone to the RJ45 MIC jack. If your microphone has a Foster (round) connector, use the adapter supplied with the cable set.

If the station microphone uses an electret element (most Icom radios), open microKEYER II and place the Electret jumper located just in front of the three trimmers in the center of the board on both pins.

WARNING: Microphones with both dynamic and electret elements are not supported. Configure the MIC (RJ-45) input for either a dynamic or electret element and do not switch types.

5. If you use a second microphone, connect your headset to the EXT MIC jack on the front panel. Serial Numbers less than 900:

If the headset microphone uses an electret element (e.g. Heil iC or typical computer headset), open the microKEYER II and move the DYN-EL jumper located behind the EXT MIC jack to the EL position.

NOTE: an electret element must be connected to both the tip and ring of the 3.5mm STEREO plug. Heil headsets will require a 3.5mm mono to stereo adapter.

Serial Numbers greater than than 900:

If the headset or boom microphone uses an Electret microphone with a STEREO plug (e.g, many computer headsets), open MK II and move the DYN-EL jumper located behind the EXT MIC jack to the EL position.

If the headset or boom microphone uses an electret mic with a MONO plug (e.g., Heil iC elements), open MK II and move the jumper to the iC position.

WARNING: Headsets with both dynamic and electret elements are not supported. Configure the EXT MIC for either dynamic or electret element and do not switch types.

6. Connect your paddles to the PADDLE jack.

7. For Icom transceivers, open MK II and install the ICVOX jumper located behind the

PTT IN jack. Otherwise, connect your transceiver PTT Out (linear) to the PTT IN jack using the supplied RCA to RCA cable.

8. If you use a foot switch, connect the foot switch to the FOOTSW jack.

9. If your transceiver's accessory port is capable of supplying +13.8 V at 500 mA, you may

install the DB37 Power jumper located in the right rear corner just in front of the +13.5 V DC jack.

NOTE: Beginning with serial number 900, this header was converted to three positions. Connecting the left pair of terminals selects the 1.38V power jack while connecting the right pair of terminals selects power from the DB37 jack.

WARNING: DO NOT use DB37 Power input with Yaesu transceivers or if the Accessory power is less than 12 Volts when transmitting (Elecraft K3).

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

Be sure to observe the proper polarity.

11. Locate but DO NOT connect the USB cable to the MK II 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 CODEC

Windows will automatically install the USB Audio Device driver to support the microHAM CODEC in microKEYER II.

Windows automatically selects any newly installed audio device as the default device for Sound playback and Sound recording. This is undesirable as Windows Sounds would be played through MK II and onto the air!

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 and 7, right click on the Speaker Icon on the task bar or open “Sounds” in the Control Panel, select "Playback Devices” and reset the Default Playback device to your computer's primary sound device.

Configuring microHAM USB Device Router

The microHAM USB Device Router (Router) program provides a Windows compatible configuration tool for microHAM USB Devices (microKEYER II as well as DIGI KEYER, microKEYER, 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 microKEYER II with Windows compatible application programs, you must be running Router and have turned on microKEYER II. Router is then configured as required by the application (logging, control or digital mode) software.

microKEYER II Status

When the USB driver is installed correctly and microKEYER II is turned on Router will show a device tab with a GREEN check beside the device name.

When Router shows a YELLOW “X” instead of a green , it means the USB driver is correctly installed but microKEYER II 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 microKEYER II. This happens when the USB cable is unplugged or the USB driver is not correctly installed.

Initial Setup

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

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 microKEYER II 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 another device that also uses virtual ports (external USB devices, bluetooth devices, mobile phones, PDAs etc.) is not connected 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 and deleted from 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 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: microKEYER II can be reset to the factory configuration by selecting Default Router Settings followed by Device | Store as Power-up Settings to save the defaults to the keyer's memory.

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: (Not used in microKEYER II)

Customizable band edge boundaries used to drive the band data output.

Options | Digital Band Map: Customizable band limits for digital mode operation. This setting is used to

automatically select VOICE or DIGITAL audio switching and the proper PTT output (PTT1/PTT2). The boundaries are necessary for transceivers which do not have a special mode for AFSK operation or do not provide this information via computer control. This primarily effects Kenwood and Ten-Tec transceivers although it is also applicable 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 MKII 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 at Audio Mixer tab and will actively control the audio devices

Automatically assign microHAM audio devices: (Not used with microKEYER II)

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.

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 (logger) 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 microKEYER II 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 microKEYER II, 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:

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

2. 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.

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

4. 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 microKEYER II and USB Interface II can be renamed to more identifiable names as shown here...

Delete - Removes a device from the Router. Only devices that

have been disconnected (those with a RED “X” on device tab) can be removed. To disconnect a device from Router, unplug the USB cable.

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 multicomputer stations or for sharing configurations between users.

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

Keyboard, Display and System tabs to the microKEYER II EEPROM. If microKEYER II is operated without connection to the computer it will use the settings stored in EEPROM. If microKEYER II 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 microKEYER II. 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: When upgrading Router, the upgrade will include the latest firmware for microKEYER II. If

the firmware is newer than the currently installed firmware, Router will automatically ask for permission to update the installed firmware the first time it connects to microKEYER II

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 (!).
