Appendix 1 - Troubleshooting Guide
Listed below are some common problems you may encounter when using
Multicom with your MFJ-1278B controller. Please follow the suggestions shown
in this list before you call MFJ for assistance! Most of our "problem" calls are
caused by simple conditions that we have outlined below. Read this section
first, then call MFJ if you still have trouble!
Q. Nothing happens when I turn on my controller after running the
software. I get the Multicom opening screen, but the controller's
sign-on message doesn't appear.
A. Make sure your RS-232 serial cable is connected properly between
the MFJ-1278B and your computer's serial port. Does the POWER
light illuminate on your controller? If not, check the connection to
your AC outlet. Have you configured your Multicom software to
work with the correct serial port on your computer? Make sure
baud rate is set to 9600, data bits is set to 8, parity is set to 0, and
stop bits is set to 1 in your Multicom configuration screen. To get
there, press the <F3> key.
Q. I'm getting something on my screen that "might" be a sign-on
message, but I can't read all the garbage. It just keeps appearing
about once every second or so. What do I do now?
A. Your controller is going through its AUTOBAUD routine. It's trying
to figure out which baud rate it needs to communicate with your
computer. Try pressing the <Enter> key several times; that should
cause the controller to "wake up" and determine your settings.
