Practice listening for more real-life words and sentences is
available using the USB Reader function. This function allows
you to send text files to the CW-Elmer. With the text files you can
listen to short messages to long books if you desire.
To send files and text MFJ-419 must be connected to a PC or
tablet computer through a USB cable with a Micro USB-B
connector. An ASCII terminal program such as “Tera Term” or
similar must be connected to the appropriate serial port given to
the MFJ-419. The terminal settings are:
9600 Baud
8 data bits
NO parity
1 stop bit
XON/XOFF handshaking
Follow your terminal program instructions to set the serial port
up. Note when the terminal program is connected to your MFJ-
419 the program may reset your MFJ-419. This is normal as one
of the serial control lines is also used for reset when using the
Arduino IDE.
