The KPG-46A connects the 8-pin microphone connector

of the transceiver to the RS-232C serial port of the comput-
er.

4-1. Preface

The repeater uses fl ash memory to allow it to be easily

upgraded when new features are released in the future.

Connect the repeater to the personal computer using the

interface cable (KPG-46A/46U/46X) (Connection is the same
as in the PC Mode.)

Note:

You can only program firmware from the 8-pin micro-

phone connector on the front panel. Using the 25-pin logic
interface on the rear panel will not work.

1. Start up the fi rmware programming software (Fpro.exe

(ver. 6.20 or later)). The Fpro.exe exists in the KPG-174D
installed folder.

2. Set the communications speed (normally, 115200 bps)

and communications port in the confi guration item.

3. Set the fi rmware to be updated by File name item.
4. Turn the repeater power ON with the [PF1] key held

down. Then, “P.G.” is displayed.

5. Check the connection between the repeater and the per-

sonal computer, and make sure that the repeater is in the
Program mode.

6. Press write button in the window. When the repeater

starts to receive data.

7. If writing ends successfully, the TX LED on the repeater

This mode cannot be entered if the Firmware Program-
ming mode is set to Disable in the Programming soft-
ware.

4-4. Function

If you press the [PF6] key while “P.G.” is displayed, the

display changes to “P G” to indicate that the write speed
is low speed (38400 bps). If you press the [PF6] key again
while “P G” is displayed, the display changes to “P G.” to
indicate that the write speed is mid speed (57600 bps). If
you press the [PF6] key again while “P G.” is displayed, the
display changes to “P.G.” to indicate that the write speed is
high speed (115200 bps).
