There is always the option of buying genuine FTDI cables, somewhat more expensive (15-20 US or so...) Available at all major component suppliers.

what are the serial protocol setting of JP1.x interfaces ? (baud rate, start bit, stop bit, parity, etc...


It is unfortunately not so easy, there is a lot of fiddling with the RTS line and such. The source is located at Soureforge and can be downloaded using svn.

BTW, it says:
Code:

   dcbSerialParams.BaudRate = 38400;
   dcbSerialParams.ByteSize = 8;
   dcbSerialParams.StopBits = TWOSTOPBITS;
   dcbSerialParams.Parity = NOPARITY;
   dcbSerialParams.fDtrControl = DTR_CONTROL_ENABLE;
   dcbSerialParams.fRtsControl = RTS_CONTROL_ENABLE;

I do not have a patience to wait many weeks for a $3 USB cable to arrive from China.....and I do not want to spend more money on this project either.
Then dealing with with fake/not fake and locked/not locked drivers , etc...

Hardware Solution:
I have all the components to put together quickly an IC version of serial interface on the weekend. 74HC266 + 5 resistor+1 capacitor+DB 9 serial connector....simple enough !
Thanks!


Why do all that? If you simply can't wait, and If you have a serial port and an RS232 to TTL converter or some old device with a max232 just connect the pins to your remote.

(obviously you need to take the power for the RS232 to TTL converter from the remote to match voltage levels)

VCC = pin 1
RTS = pin 2
GND = pin 3
TXD = pin 4
pin 5 unconnected
RXD = pin 6

I have been using this for years and it works great. If you really need it, I can post a schematic of my RS232 to TTL board.

You can do a lot of programming without a cable. What exactly do you need? We can probably show you how to solve your immediate problem by direct programming. Then you can wait 3 weeks for the proper cable.

Or just spend $5 to get a cable shipped from the USA:
