5-2. Connection procedure
1. Connect the transceiver to the computer using the inter-
face cable.
Note:
• You must install the KPG-36U driver in the computer to
use the USB programming interface cable (KPG-36U).
2. When the POWER is switched on, you can immediately
enter user mode. When the PC sends a command, the
transceiver enters PC mode, and "PROGRAM" is dis-
played on the LCD.
When data is transmitting from the transceiver, the red
LED blinks.
When data is receiving by the transceiver, the green LED
blinks.
Note:
The data stored in the computer must match the "Model
Name" when it is written into the flash memory.
5-3. KPG-36A description
(PC programming interface cable: Option)
The KPG-36A is required to interface the transceiver to
the computer. It has a circuit in its D-sub connector (KPG-36A:
9-pin) case that converts the RS-232C logic level to the TTL
level.
The KPG-36A connects the universal connector of the
transceiver to the RS-232C serial port of the computer.
5-4. KPG-36U description
(USB programming interface cable: Option)
The KPG-36U is a cable which connects to a USB port
on a computer.
When using the KPG-36U, install the driver software in
the computer. The KPG-36U driver runs under Windows XP,
Vista, 7 or 8.
The latest version of the USB driver is available for down-
load from the following URL:

5-5. Programming software KPG-111D/111DN
(Ver. 4.40 or later) description
The FPU is the programming software for the transceiver
supplied on a CD. This software runs under Windows XP,
Vista, 7 or 8 on a PC.
The data can be input to or read from the transceiver and
edited on the screen. The programmed or edited data can be
printed out. It is also possible to tune the transceiver.
