3-1. Preface
The repeater is programmed by using a personal com-
puter, programming interface (KPG-46A/46U) and FPU (pro-
gramming software).
The programming software can be used with a PC. Fig-
ure 1 shows the setup of a PC for programming.
3-2. Connection Procedure
1. Connect the repeater to the computer using the interface
cable.
Note:
• You must install the KPG-46U driver in the computer to
use the USB programming interface cable (KPG-46U).
2. When power is applied, the user mode is entered im-
mediately. When the PC sends a command, the repeater
enters the PC mode and displays “PC” on the 7-segment
LED. When data is being transmitted to the PC from the
repeater, the TX LED lights. The BUSY LED lights when
data from the PC is being received by the repeater.
Note:
• The data stored in the personal computer must match
the model type, when it is written into the flash memory.
