Configuring microHAM USB Device Router

The MicroHAM USB Device Router (Router) program provides a Windows compatible configuration tool for

microHAM USB Devices (DIGI KEYER 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 DIGI KEYER with Windows compatible application programs it is necessary to have

installed the USB driver, started the Router, and applied power to DIGI KEYER 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.

DIGI KEYER Status

When the USB driver is installed correctly and DIGI

KEYER is powered from a radio or external 12V DC supply

Router will show a device tab with a GREEN check

beside the device name (DIGI KEYERI).

When Router shows a YELLOW “X” instead of a green ,

it means the USB driver is correctly installed but DIGI

KEYER is not receiving power from the radio or external

supply.

When Router shows a RED “X” insted of a green , it

means the device is disconnected and Router does not

see the USB part of DIGI KEYER.

This happens when the USB cable is unplugged or the

USB driver is not correctly installed.

Initial Setup

Router must be used to configure DIGI KEYER for

proper operation. The device configuration tab (in the

red rectangle) is used to setup each part of the DIGI

KEYER – virtual ports for communicating with the

application (Ports), audio levels, PTT and keyboard FSK

(Keying), and stored FSK messages (FSK Messages).
