MFJ-1289 Multicom User's Manual Page 22
If you are using MFJ MULTICOM with the MFJ-1270B or the MFJ-1274 make
sure that the TNC terminal baud rate is set to 9600. You can verify the terminal
baud rate by checking the DIP switches on the rear of the TNC. Set switch
position #5 to ON then turn the TNC on. Note that there should always be two
baud rate switches set ON - one for the radio rate (switch 6, 7, or 8) and one for
the terminal baud rate (switch 1, 2, 3, 4, or 5).
Turn on your TNC. You should see characters scroll across the screen. When
an asterix appears press <Enter>. If you do not see any characters just press
<Enter> several times. The TNC should sign-on by sending a message to the
terminal screen. The sign-on message will appear on an MFJ-1278B as below.
If the controller failed to sign on, press <F3>. Multicom will display the setup
screen again. Reset the following parameters as below:
