3-1. Preface
The TK-2160 transceiver is programmed using a personal
computer, a programming interface (KPG-22) and programming
software (KPG-82D).
The programming software can be used with an IBM PC
or compatible. Figure 1 shows the setup of an IBM PC for
programming.
3-2. Connection procedure
1. Connect the TK-2160 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 transmitting from the transceiver, the red
LED lights.
When data is received by the transceiver, the green LED
lights.
Notes:
·
The data stored in the personal computer must match the
model type when it is written into the EEPROM.
·
Change the TK-2160 to PC mode, then attach the interface
cable.
3-3. KPG-22 description
(PC programming interface cable: Option)
The KPG-22 is required to interface the TK-2160 with 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-2160
to the computer's RS-232C serial port.
3-4. Programming software description
KPG-82D is the programming software for TK-2160
supplied on a CD-ROM. This software runs under Windows
98, ME, Windows 2000 or XP on an IBM-PC or compatible
machine.
The data can be input to or read from TK-2160 and edited
on the screen. The programmed or edited data can be printed
out. It is also possible to tune the transceiver.
