2-3. Connection procedure
Connect the transceiver to the personal computer (IBM
PC or compatible) using the interface cable (KPG-46/46A) and
USB adapter (KCT-53U: when the interface cable is KPG-46A,
the KCT-53Ucan be used.). (Connection is the same as in the
PC Mode.)
2-4. Programming
1. Run the PC firmware programming software (Fpro.exe).
2. Set the communication baud rate to 19,200 bps. (Do not
use other baud rates, as they cannot be used for commu-
nications.)
3. Select the new firmware file of the KPE-2.
4. While press the [ ] key, turn the transceiver power on.
Then release the [ ] key, “PROG 19200” will appear on
the transceiver display.
5. Confirm the connection between the transceiver and the
PC.
6. Press the “Write” button on the PC screen. “PG” will
appear on the transceiver display when data reception be-
gins.
7. When data reception has completed, the transceiver will
calculate the checksum and indicate the results.
8. To repeat the data writing process on additional transceiv-
ers, repeat steps 4 to 7.
Notes:
• The TK-90 hardware can use only a baud rate of 19,200
bps for communications.
• The transceiver baud rate cannot be changed.
• A communication error where occur and programming
cannot be performed if the firmware programming soft-
ware (Fpro.exe) is set to a baud rate other than 19,200
bps.
• It takes approximately 2 minutes to reprogram a single
transceiver.
2-5. Function
1. While “PROG 19200” appears on the display, you can cal-
culate the checksum by pressing the [ ] key. The results
will be indicated on the display.
2. While the checksum results are displayed, press the [ ]
key again to return the display to “PROG 19200”.
