Operation
The TK-2107 VHF FM Transceiver operates in three modes: User Mode, PC Mode, and Manufacture Mode. User Mode is for normal operation, PC Mode allows for various settings through a PC using the FPU and RS-232C port, and Manufacture Mode is used for realigning settings during manufacturing. To enter User Mode, simply power on the device. PC Mode requires connection to an IBM PC compatible machine controlled by the FPU. The transceiver is programmed using a personal computer, a programming interface (KPG-22), and programming software (KPG-55D). The KPG-22 interface cable connects the TK-2107 to the computer’s RS-232C serial port, converting RS-232C logic levels to TTL levels. The KPG-55D software allows programming of the TK-2107 radios via the interface cable.
