3-1. Preface

The TK-3160 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-3160 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-3160 to PC mode, then attach the interface

cable.
