MFJ-1278 & MFJ-1278T Fast-Start Manual

1

Introduction

This MFJ-1278 Fast-Start Manual is intended to provide you with the minimum Information neces-
sary  to  install  your  MFJ-1278  or  MFJ-1278T  "Turbo"  Multi-Mode  as  quickly  as  possible.  For  detail
operation, please see the main instruction manual.

The difference between the MFJ-1278 and the MFJ-1278T is that the MFJ-1278T has the 2400 mo-
dem installed. If your MFJ-1278 does not have the 2400 modem installed, it can be purchased sep-
arately  (Model  MFJ-2400)  and  installed  by  the  user.  With  the  2400  modem  installed,  your  MFJ-
1278 can operate 300 baud, 1200 baud and 2400 bps packets.

The Computer Installation section assumes that you have purchased one of the MFJ Starter Packs.
If you are not using the MFJ Starter Pack, you should refer to the main MFJ-1278 Owner's Manual
for Computer interface connections. However, you may still use the Radio Installation and the oth-
er parts of the Fast-Start manual.

Your  MFJ  Starter  Pack  consists  of  terminal  Software  and  a  serial  cable  to  connect  between  the
MFJ-1278 and your Computer.

The Starter Packs available are MFJ-1289 for IBM and compatible Computers, MFJ-1282B for Com-
modore 64/128 Computers and MFJ-1287B for the Macintosh Computer.

MFJ-1289  Starter  Pack  includes  the  MULTICOM  advanced  terminal  program.  MULTICOM  supports
multi-gray  levels  FAX  and  SSTV  receiving  and  transmitting.  It  also  supports  VGA  packet  picture
passing. Other unique features this program gives you are: Auto-Router™ lets you store digipeater
node  routes  for  easy  execution,  Multi-Word™  makes  it  easy  for  you  to  transmit  any  portion  of  a
file,  Packet  Multi-Plex™  lets  you  send  and  receive  packet  messages  during  binary  file  transfer.
MULTICOM  is  fully  menu  driver,  and  it  is  very  easy  to  use.  It  has  dedicated  function  buffers  for
each mode of Operation.

MFJ-1289 MULTICOM is highly recommended if you are using an IBM or compatible Computer with
your MFJ-1278.

MFJ-1282B for the Commodore C64/128 and MFJ-1287B for the Macintosh Computers also support
Multi-Gray FAX/SSTV Operation.
