Loading a Memory Block from the Computer
•
Type “~>#”, where # is a digit in the range of 1 to 4 for the message number. The word
RECEIVING will appear. The unit now is ready to receive data from your computer.
•
Begin sending the data from the computer, and a progress indicator will appear on line two of
the display. Invalid data will be ignored during the loading process. To stop loading data at
any time, press the Mode button.
•
The MFJ-464 automatically inserts an open square bracket "[" at the beginning of every
message. This is its "beginning-of-message" indicator. When you press Menu or ENTER to
end a transfer, the unit inserts a close square bracket "]" as its "end-of-message" indicator. If
you insert "[]" at the end of your message file, the MFJ-464 will stop the transfer
automatically when the close square bracket “]” is received. If the unit runs out of memory,
the transfer will be stopped automatically.
•
When the message transfer is completed, the unit will display RECEIVED XXXX where
XXXX is a four-digit number indicating the number of characters received. This number
includes the opening and ending message delimiters "[" and "]", plus any tabs and carriage
returns.
•
Press any button or paddle to return to normal operation.
WARNING: Do not turn the power off while loading the memory; otherwise, the
memory can be corrupted.
One way of speeding data transfer is to configure your terminal program to strip out linefeeds
that follow carriage returns. While computers store a carriage return as two characters (the
carriage return followed by a linefeed), the MFJ-464 stores only the carriage return and generates
the linefeed following it during playback. The additional linefeed thus does not need to be
transferred to the Keyer.
Sending Contents of a Memory Block to the Computer
•
Configure your terminal program to receive ASCII data.
•
Type “~<#”, where # is a digit in the range of 1 to 4 for the message. SENDING XXXX will
appear on the display, where XXXX is a four-digit number indicating the number of
characters in the message plus the message delimiters “[” and “]”.
•
A progress indicator will appear on the second line of the display to indicate the percentage
of the message that has been sent.
•
To stop the transfer at any time, press Mode or ESC.
•
Return to normal operation when the transfer is completed.
