DIGI KEYER 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.
DIGI KEYER is connected to the computer using a single A-B USB cable which is included.
The transceiver and DIGI KEYER 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 model. The cable carries power
for DIGI KEYER, audio, CAT control and keying. The appropriate cable for the target radio is specified
when DIGI KEYER is purchased.
If a Windows PC running the "
micro
HAM USB Device Router" program is connected, DIGI KEYER works
as a computer interface. It transfers all digital and analog signals generated by the computer logging
program or digital mode package 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 DIGI KEYER. DIGI KEYER processes this data and sends it
to the physical ports of transceiver as CAT, CW, and PTT functions.
The USB sound processor in DIGI KEYER independently provides analog to digital conversion of audio
from the transceiver and transfers it via USB to the computer where the Windows sound 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.
micro
HAM 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 and may be used by any application
compatible with those operating systems.
