4 - INSTALLATION
Installing USB Interface II consists of several steps:
1) prepare USB Interface II to work with your radio
2) install microHAM USB Device Router (the control and interface software)
3) configure Router
Preparing USB Interface II for Use
1. Remove the top cover from the USB Interface II and set the CAT jumpers as shown in the following
chart. The CAT interface jumpers must be configured to select the proper level for each radio type.
RS-232 levels:
All transceivers with RS-232 CAT inputs.
IF-232 levels:
Kenwood: TS-140, 440, 450, 680, 690, 711,
790, 811, 850, 940, 950
FIF-232 levels:
Yaesu: FT-100, 736, 747, 757GXII, 767, 817,
840, 857, 890, 897, 900, 980, 990, 1000,
1000D
CI-V levels:
Icom: all radios
TenTec: all rigs with 3.5mm jack
NOTE: the CAT interface is not configured at the factory.
2. Plug the DB15M on the radio cable set into the DB15 connector on the rear panel of the DIGI
KEYER and plug ALL connectors from the cable set to the appropriate jacks at the rear panel of
your transceiver. Each connector on the radio interface cable is marked same as the matching jack
on your transceiver.
3. If the radio cable ends with leads for external power, connect these leads to a 12-16V DC power
supply. Be sure to observe the proper polarity.
RS232
IF232
FIF232
CI-V
4. Prepare but do not connect the USB cable from USB Interface II to your computer.
5. If you will be installing on a Windows computer, skip to “Installing microHAM USB Router”

Mac OS X INSTALLATION
1. Insert the microHAM CD in your
CDROM/DVD drive and navigate to
Drivers/OS-X or use your web browser to go
to http://www.ftdichip.com/Drivers/VCP.htm
and down load the latest driver image for
OS-X.
2. Open FTDIUSBSerialDriver_v2_2_14.dmg
by clicking on it.
3. For OS-X 10.4, 10.5 or 10.6 open
FTDIUSBSerialDriver_10_4_10_5_10_6
and follow the instructions to install.
4. Plug in the USB cable
5. Turn on the radio or external power supply.
6. Follow your software developer's instructions to configure their application to work with USB
Interface III.
MICROSOFT WINDOWS INSTALLATION
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.
1.
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/downloads.html.
2.
If you download an updated package, right click
on "urouter_release_xx_xx.exe" (xx_xx is version)
and choose “Run as administrator” to start
installation.
3. When the Router installation is completed, click
"Finish" to launch Router for the first time.
4. 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 (USB Interface II as well as microKEYER, CW Keyer and USB Interfaces) and
software interface to other Windows applications (loggers, digital mode software, etc.). The software
interface is provided as Virtual Serial Ports.
To configure and use USB Interface II with Windows compatible application programs it is necessary to
have installed the USB driver, started the Router, and applied power to USB Interface II by turning on the
attached radio or external power supply. Router is then configured to match the requirements of the
application (logger or digital mode) software.
USB Interface II Status
When the USB driver is installed correctly Router will show a
device tab with a GREEN check beside the device name (USB
Interface II). The yellow POWER LED must also be ON for USB II
to operate properly. DO NOT proceed with setup unless you have
both a green check and the yellow POWER LED is ON.
Creating and Using Virtual Serial Ports
microHAM Router provides a set of virtual serial ports which allow Windows applications (loggers and digital
software) to work with USB Interface 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 function (radio control,
PTT, CW, FSK, etc.) to each virtual port.
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 used by another USB device.
Router will not allow using a COM port number which is already
present in the system but ports are sometimes hdden. If a another
device which also uses virtual serial ports (external USB devices,
bluetooth devices, PDA 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.
IMPORTANT WARNING: Before creating virtual COM
ports, attach all external devices you will use with the
computer. Restart Router and then create the virtual
COM ports.
Virtual ports are created 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 and
clicking several port numbers. Creating virtual ports may take a while, be patient.
