MFJ-1278B MULTI-MODE ADVANCED OPERATION
Packet Picture Transfer
The MFJ-1278B gives you the unique ability to transmit and receive Packet Pictures. Unlike
the binary file transfer ability common to all packet controllers that lets you transmit and
receive picture files, MFJ-1278B lets you transmit and receive actual packet pictures directly.
You can also transmit and receive FAX, SSTV and other graphics formats pictures with the
MFJ-1278B in the VHF packet mode. Packet pictures received are directed to and printed on
the built-in printer port on the MFJ-1278B. Any EPSON ™ or IBM ™ graphics compatible
printer may be used. Packet pictures can also be sent to the computer screen if special
software, such as the MFJ-1284, is used.
Printing Packet Pictures thru Built-in Printer Port
This routine is for users who do not have a special terminal program like, MFJ MultiCom™
to receive high resolution Packet Pictures. Packet picture data transmitted from the
connecting packet station is received and data is sent directly to the printer attached to the
MFJ-1278B, without any intervening modification. Therefore, all data MUST use the same
printer control codes that your printer uses. Typically EPSON format codes will be used.
The PKTPIX command provides a method for the MFJ-1278B to print packet pictures other
graphics-format data transmitted by another station in the VHF packet mode. When you set
PKTPIX, your MFJ-1278B becomes ready to print graphics data.
Using PKTPIX
Packet picture printing to the MFJ-1278B printer port requires you to first establish a packet
connection with the station who is going to send the picture. Note that you won't be able to
call up PKTPIX until the connection is made. You must have the printer powered and
selected before MFJ-1278B will let you use the PKTPIX command.
Once these conditions are met, all data received over the packet link are sent directly to the
printer. You can exit PKTPIX by using the escape-to-cmd: mode sequence for
TRANSPARENT connections. Press CTRL-C three times within one CMDTIME increment
(default), or asynchronous BREAK.
Packet Picture transfer to the computer screen
Packet pictures can also be received and displayed on the computer screen in real time. To
achieve this a special terminal program must be used. The MFJ Starter Pack for IBM and
compatible computer includes terminal program, MultiCom™ that allows you to transmit and
receive SVGA, VGA, EGA or CGA pictures in real time and display them on the screen.
Multicom can transfer binary files in additional to picture files. It also allow you to set up
your personal packet pictures bulletin board. Graphics that you create with certain "paint"
software, such as QSL cards, drawings and pictures can be saved and transmitted to the
connecting packet station with Multicom. Also, pictures created with digitizers, such as the
