DigiMaster DUAL CHANNEL USB Audio-Data Interface
Suitable for ALL afsk data modes and is perfect for programs including MixW2 and other
Windows afsk software.
The interface connects to the PC via the PC’s standard powered USB port, using a
standard USB cable (A to B).
The USB cable from the PC connects to the interface via the interfaces standard type B
USB socket.
When this cable is connected, Windows will recognize the USB connection and, depending
on your Windows version, will either automatically install the drivers required or prompt
you to install them. The installation is automatic with Windows XP.
Should you need to install the drivers yourself, full step by step instructions are provided
on the and can be downloaded from the website.
Once the drivers have been installed, Windows will inform you that the device is ready
for use.
The drivers will have installed two “virtual” comports to your PC.
Since this is a USB comport connection and not a “real” comport, this comport is termed
a “virtual” comport.
This comports will appear in Windows->Device Manager as a standard comport, and will
be used by programs running under Windows as a standard comport.
Take note of the number of the new comports provided. You should configure your
software to use this new comport. The higher value comport is used for the CAT
connection, the lower value comport is used to activate PTT by the RTS line.
If the new comports values lies outside the range useable by your software, you can use
Windows -> Device Manager to remap it to a value that lies in the range allowed by your
software.
When you connect the interface to your PC you will notice that Windows tests the virtual
comports. If your radio is attached during this process it will of course switch into TX
then RX as this process happens.
You can now plug in your cable that connects the unit to the radio.
There are many cables available to connect to your radio(s).
Plug the other end of this cable into your radio and run your software.
It is important that the unit is plugged into the PC and that Windows has recognized your
USB interface BEFORE you start your software, otherwise your software will not be able
to find the driver to control the interface.
For ALL models of the DigiMaster Audio-DATA interfaces, it is important that you
configure your software to activate your radios PTT via the interface. NOT via the CAT.
This is because many radios, when put into TX via the CAT open the “mic” rather than
the DATA input socket for transmission. ALL Kenwood radios for instance will only
transmit DATA via the 13 pin acc socket when the PTT on the 13 pin socket is activated.
