9 - SPECIFICATIONS

DigiKeyer is a multi-mode interface between computer and transceiver. It has been optimized for amateur

digital modes and includes a high performance USB sound processor.

DigiKeyer is connected to the computer using a single A-B USB cable which is included.

The transceiver and DigiKeyer are connected by single radio cable terminated on one side by a DB15M and

on the other side by the appropriate plugs for the specific transceiver. The cable carries power for

DigiKeyer, audio, CAT control and keying. The appropriate transceiver interface cable is specified when

DigiKeyer is purchased.

If a Windows PC running the "microHAM USB Device Router" program is connected, DigiKeyer works as a

computer interface and sound card. It transfers all control signals generated by the application program

between the computer and transceiver. Software compatibility is provided by using virtual serial ports.

Router monitors these virtual ports and transfers any data or commands by USB to the micro controller in

DigiKeyer. DigiKeyer processes this data and sends it to the physical ports of transceiver as CAT, CW, and

PTT functions.

The USB sound processor in DigiKeyer independently provides analog to digital conversion of audio from

the transceiver and transfers it via USB to the computer where the operating system processes that data as

a “sound card.” The USB sound processor also receives digital audio from any applications running on

computer and converts that data into audio signals to modulate the transceiver.

microHAM Device Router is not required in order to enable the USB sound functions. The USB sound

processor is supported directly by Windows, Apple OS 10, and LINUX.. It may be used by any application

compatible with those operating systems.
