MFJ-1278B MULTI-MODE BASIC OPERATION

OPERATIONAL MODES

Verifying Operation Status

Upon initial power up, the MFJ-1278B defaults to VHF Packet mode. The radio baud rate defaults to 1200 baud. Radio port 1 is the default radio connection. You can verify the operating status of the MFJ-1278B at any time by using the command MODE after the display of the CMD: prompt. To check operation mode, type:

MODE <ENTER>

The MFJ-1278B will respond with modem status display lines followed with the cmd: prompt.

Mode Switching With the MODE Command

Since the MFJ-1278B is a multi-mode controller, you will need to familiarize yourself with the commands for changing operating modes from one to another.

The MFJ-1278B provides an easily used command to change the mode of operation. The MODE command allows you to enter any operational mode. The MODE command also enables the selection of any desired radio baud rate and modem. Table 4-3 lists the valid codes that are used by the MODE command. The format for the MODE command is:

MODE xx,bbbb,m <ENTER>

Where xx is a 2 letter operational mode code as listed in Table 4-3, bbbb is the desired baud rate or speed, and m is the desired modem as listed in Table 4-1. Leaving the m parameter off of the MODE command, will cause the MFJ-1278B to select the default modem for the selected mode using the modem as listed in Table 4-1. Most of the time, there is no need to alter the baud rate settings, because the default settings are sufficient. So to specify HF RTTY operation at the default baud rate of 45 baud and using the default narrow shift modem, for example, you would type:

MODE HB <ENTER>

The user can alter any of the three parameters without having any effect on the other two. We can change the operational mode to HF RTTY at 110 baud, just by adding the number 110 on the end of the MODE command entry. You would do this by entering the following command:

MODE HB,110 <ENTER>

Similarly, to select the wide shift modem without changing either the operating mode or the baud rate you would type:

MODE HB,110,V <ENTER>
