24 PC MODE
PC Mode can be switched from the User Mode. In this
mode, you can control the TKR-750/850/751/851 through
the PC. You can read/write the program and adjust
parameters by KPG-91D.
(Refer to 1.5 Mode.)
Data communication is made through the microphone
connector (8-pin connector) located on the front panel
and the control interface jack, which complies with the
RS-232C standard (25-pin connector) located on the rear
panel. TKR-750/850/751/851 returns to User Mode
automatically after communication with PC.

24.1 PC Programming Mode
This function allows you to write the configuration data,
such as frequencies, to the flash memory or read the data
from the memory with the ASCII characters and
commands transmitted from KPG-91D. The baud rate is
9600 bps.

24.2 PC Test Mode
PC Test Mode allows you to check TKR-750/850/751/
851's performance. In this mode, you can make various
adjustments, such as checking the RF environment of the
location and the adjustment of the reception frequency,
before installing or operating the TKR-750/850/751/851. It
can start a test without writing data since the encode/
decode signalling and the test frequency are already
memorized.
(Refer to 24.2.1 Test Signalling.)
You can select the following functions.
