SYSTEM SETUP & OPERATION
2.1
INSTALLATION
Connecting the MFJ-1205 is incredibly simple. First, plug the unit into any free USB port on your
computer. Second, plug the audio cable into the appropriate radio ports. Make sure that your
computer has properly mounted the interface, and you’re good to go! One of the benefits to using
the MFJ-1204 is that if you ever upgrade your radio, you don’t have to purchase an entirely new
unit. Simply order a new cable and jumper board, swap them out with the old ones, and reconnect!
Table 1 lists all of the current jumper board and cable combinations available for the MFJ-1205.
Once connected to your computer, the MFJ-1205 will be recognized and mounted as an audio
device. The exact details of this will vary depending on your operating system. Look for “USB
Audio Device.” During this process the green LED may flash about once per second depending on
the OS, but will glow steadily once ready. At this point the MFJ-1205 is ready to be used by your
favorite software.
