5.PC Mode
5-1. Preface
The TK-3140 transceiver is programmed by using a personal
computer, programming interface (KPG-36) and programming
software (KPG-74D).
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-3140 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-3140 to PC mode, then attach the interface
cable.
5-3. KPG-36 description
(PC programming interface cable: Option)
The KPG-36 is required to interface the TK-3140 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-36 connects the universal connector of the TK-
3140 to the computers RS-232C serial port.
5-4. Programming software description
The KPG-74D programming disk is supplied in 3-1/2" disk
format. The software on this disk allows a user to program TK-
3140 radios via programming interface cable (KPG-36).
5-5. Programming with IBM PC
If data is transferred to the transceiver from an IBM PC with
the KPG-74D, the destination data (basic radio information)
for each set can be modified. Normally, it is not necessary to
modify the destination data because their values are
determined automatically when the frequency range (frequency
type) is set.
The values should be modified only if necessary. Data can
be programmed into the flash memory in RS-232C format via
the universal connector.
6. Firmware Programming Mode
6-1. Preface
Flash memory is mounted on the TK-3140. This allows the
TK-3140 to be upgraded when new features are released in
the future. (For details on how to obtain the firmware, contact
Customer Service.)
6-2. Connection procedure
Connect the TK-3140 to the personal computer (IBM PC or
compatible) with the interface cable (KPG-36). (Connection is
the same as in the PC Mode.)
6-3. Programming
1. Start up the programming software (Fpro.exe).
2. Set the communications speed (normally, 57600 bps) and
communications port in the comfiguration item.
3. Set the firmware to be updated by file name item.
4. Turn the TK-3140 power ON with the [S] switch held down.
When "PROG 57600" appears, release your finger from
the switch.
5. Check the connection between the TK-3140 and the
personal computer, and make sure that the TK-3140 Is in
the Program mode.
6. Press write button in the window. A window opens on the
display to indicate progress of writing. When the TK-3140
starts to receive data. the [P] icon is blinking.
7. If writing ends successfully, the LED on the TK-3140 lights
and the checksum is displayed.
9. If you want to continue programming other TK-3140 s,
repeat steps 4 to 7.
Notes:
q
This mode cannot be entered if the Firmware Programming
mode is set to Disable in the Programming software (KPG-
74D).
q
When programming the firmware, it is recommend to copy
the data from the floppy disk to your hard disk before update
the radio firmware.
Directry copying from the floppy disk to the radio may not
work because the access speed is too slow.
6-4. Function
1. If you press the [Side2] switch while "PROG 57600" is
displayed, the checksum is displayed. If you press the
[Side2] switch again while the checksum is displayed,
"PROG 57600" is redisplayed.
2. If you press the [Side1] switch while "PROG 57600" is
displayed, the display changes to "PROG 19200" to indicate
that the write speed is low speed (19200 bps). If you press
the [Side1] switch again while "PROG 19200" is displayed,
the display changes to "PROG 38400", and the write speed
becomes the middle-speed mode (38400 bps). If you press
the [Side1] switch again while "PROG 38400" is displayed,
the display returns to "PROG 57600".
Note:
Normally, write in the high-speed mode.
