The FTDI cable is a USB to Serial (TTL level) converter which allows for a simple way to connect TTL interface devices to USB. The I/O pins of this FTDI cable are configured to operate at 5V.
The FTDI cable is designed around an FT232RQ, which is housed in a USB A connector. The other side of the cable is terminated with a 0.1" pitch, 6-pin connector with the following pinout: RTS, RX, TX, 5V, CTS, GND (RTS is the green cable and GND is black).
Cable works great, but wish the colors were standard
I am not an electronics chap by a long shot, just needed a cable to complete my EQ mount setup, so needed to build my eqdir cable
Which is pretty straightforward if you have standard colors to play with, check here: http://eq-mod.sourceforge.net/eqdirect2.htm
But remapping the colors by looking at the spec wasnt that tough, so if I can do it, anyone can
Overall works as expected, build is good and price is fantastic. Thanks
