- KPG-22 description
(PC programming interface cable: Option)
The KPG-22 is required to interface the TK-3107 with the
computer. It has a circuit in its D»subconnector (25-pin) case
that converts the RS»2320 logic level to the TTL level. The
KPG-22 connects the side panel jacks of the TK-3107 to the
computer's RS-232C serial port.

Programming software description

The KPG-55D Programming Disk is supplied in 3-1/ " the disk
format. The Software on this disk allows a user to program the
TK-3107 radios via a Programming interface cable (KPG-22).

RF Power meter 4-

. Programming with IBM PC

If data is transferred to the transceiver from an IBM PC with
the KPG-55D. 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 EEPROM in RS-2320
format via the SP MIC plug.

In this mode the PTI' line operates as TXD and RXD data lines
respectively.
