Сама футаба об этом не знает и думает что:
The data port is strictly for factory use only.
Both the R6014FS and the R608FS are electronically identical the only difference being physical in that the RR6014FS has a larger case, both main IC’s are mounted on the same side PCB, the main PCB is larger and that it has more end pins.
The three IC’s used in the Rx’s are
Micro Linear 2.4Ghz FHSS transceiver IC 2724DH
Futaba custom IC FP9067
Renesas Technology Microprocessor H8/36087
The data port consists of three pins. One pin connects to –ve (common). The other two go to the H8/36087 Renesas Technology Microprocessor, one connects to P21 RxD (receive data) port and the other to P22 TxD (transmit data) port in other words these ports are the serial communications interface of the Microprocessor.
The Microprocessor contains flash memory and has an on board-programming mode. What this means is the data port is used to program the Microprocessor with controlling software at the factory. This data port also allows verification of the controlling software that it has been correctly written to the flash memory. Flash memory size is 56kbytes.
