4. Checksum
Executing this function, "-PC-" appears on the display of
TK-373G while calculating the checksum .
When the calculation is completed, the display returns to
normal and PC displays the checksum of the radio.
5. PC Mode
5-1. Preface
The TK-373G transceiver is programmed using a personal
computer, a programming interface (KPG-22) and
programming software (KPG-76D).
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-373G to the personal computer with the
interface cable.
2. When the POWER is switched on, user mode can be
entered immediately. When the PC sends a command, the
radio enters PC mode.
When data is transmitted from transceiver, the red LED blink.
When data is received by the transceiver, the green LED blinks.
6. Firmware Programming Mode
6-1. Preface
Flash memory is mounted on the TK-373G. This allows the
TK-373G 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-373G to the personal computer (IBM PC
or compatible) with the interface cable (KPG-22). (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 Setup item.

Notes:
• The data stored in the personal computer must match model
type when it is written into the flash memory.
• Change the TK-373G to PC mode, then attach the interface
cable.
5-3. KPG-22 description
(PC programming interface cable: Option)
The KPG-22 is required to interface the TK-373G 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-22 connects the SP/MIC connector of the TK-
373G to the computers RS-232C serial port.
5-4. Programming software description
The KPG-76D programming disk is supplied in 3-1/2" disk
format. The software on this disk allows a user to program the TK-
373G radios via a programming interface cable (KPG-22).
5-5. Programming with IBM PC
If data is transferred to the transceiver from an IBM PC with
the KPG-76D, 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.

3. Set the firmware to be updated by file name item.
4. Hold down the [Side1] and [Side2] switches on the TK-373G,
and press the power switch.
When the [Side1] and [Side2] switches are held down for
two seconds, "PROG 576" appears on the display and
the LED lights orange. When "PROG 576" is displayed,
release the switches.
5. Check the connection between the TK-373G and the
personal computer, and make sure that the TK-373G is in
Program mode.
6. Click "write" button in the window. A window opens on the
display to indicate the writing progress. When the TK-373G
begins to receive data, the LED lights green.
7. When data is received successfully, a checksum appears
on the display.
