Futaba Radio Pinout for DIN 6?

[Skylined]

I've already searched the forum but I didn't get the information that I need.

I've taken a look at these two pages

I would like to power the radio directly from my USB port, so I don't have to use the Tx batteries, so I would like to know if any of these pins (4 - 5 - 6) is connected to the batteries' +V.


I have a FP-T4NBF with that DIN 6 connector, but no wires in those pins.

Sorry I don't think you'll be able to connect the TX directly to the USB port for two reasons

1) - The Max current the USB port can supply is 500mA, and chances are your TX will draw more than that

2) - USB voltage is +5v max, and most transmitters require 9.6v

Those pin-outs are for buddy port connections between slave and master transmitters, and for use with simulator interfaces which take the PPM signals from the radio and convert them into the format required by the software. If this is waht you are after then there are lots of interface examples on the web and in this forum (look at the stick above)

It's actually Pin 1 which is used for power into a Futaba Tx....but as Malc says you need 9V+.

1- The current drain of this radio is just under 200mA
2- They require 9.6V to transmit, but 5V is enough to use the radio with simulators, and that's what I'm doing.

I've already used 2 radios powering them from the USB port, and I've already done 2 parallel port interfaces.


Pin 1 isn't connected directly to the battery.
