5-1. Preface
The TK-780 transceiver is programmed by using a per-
sonal computer, programming interface (KPG-46) and pro-
gramming software (KPG-60D).
The programming software can be used with an IBM PC
or compatible. Figure 1 shows the setup of an IBM PC for
programming.
5-2. Connection Procedure
1. Connect the TK-780 to the personal computer with the
interface cable.
2. When the Power switch on, user mode can be entered
immediately. When PC sends command the radio enter
PC mode, and "PROGRAM" is displayed on the LCD.
When data transmitting from transceiver, the red LED is
blinking.
When data receiving to transceiver, the green LED is
blinking.
Notes :
• The data stored in the personal computer must match
model type, when it is written into the flash memory.
• Change the TK-780 to PC mode, then attach the interface
cable.
5-3. KPG-46 Description
(PC programming interface cable : Option)
The KPG-46 is required to interface the TK-780 to the
computer. It has a circuit in its D-subconnector (25-pin) case
that converts the RS-232C logic level to the TTL level.
The KPG-46 connects the modular microphone jack of
the TK-780 to the computers RS-232C serial port.
5-4. Programming Software KPG-60D Description
The KPG-60D is the programming software for the trans-
ceiver supplied on two 3.5" floppy disks. This software runs
under MS-Windows 95 or later on an IBM-PC or compatible
machine.
The data can be input to or read from the transceiver and
edited on the screen. The programmed or edited data can
be printed out. It is also possible to tune the transceiver.
We recommend that install the KPG-60D for example to
hard disk first then use it.
