3-1. Preface

The TK-7102H transceiver is programmed using a per-

sonal computer, a programming interface (KPG-46) and pro-

gramming software (KPG-70D).

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-7102H to the personal computer with the

interface cable.

2. When the Power is switched on, user mode can be en-

tered immediately. When the PC sends a command, the

radio enters PC mode.

When data is transmitted from transceiver, the red LED

blink.

When data is received by the transceiver, the green LED

blink.

In the PC mode, 4CH LEDs, [MON] LED and [●] LED are

turned on.

Notes :

•The data stored in the personal computer must match

model type when it is written into the EEPROM.

•Attach the interface cable, then change the TK-7102H to

PC mode.

3-3. KPG-46 Description

(PC programming interface cable : Option)

The KPG-46 is required to interface the TK-7102H to 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-46 connects the modular microphone jack of the

TK-7102H to the computers RS-232C serial port.

3-4. Programming Software Description

The KPG-70D programming disk is supplied in 3-1/2" disk

format. The software on this disk allows a user to program

TK-7102H radio via a programming interface cable (KPG-46).

3-5. Programming With IBM PC

If data is transferred to the transceiver from an IBM PC

with the KPG-70D, the destination data (basic radio informa-

tion) for each set can be modified.
