******Warning Buggy Chips******
There have been batches of cheap Chinese cables doing the rounds of Ebay and other retail outlets, and a small amount have turned up in our stock. The main difference is that you must use old FTDI drivers to get these cables to work. The driver information is given below:


These cables are guaranteed to run on the FTDI driver V2.08.14.0 as given in the link above.

It is easier to sell these off at very cheap prices as a buggy chip, rather than run extensive tests on the current suspicious stock. You may get a good one that works with the latest drivers, or you may get a buggy one that requires you to run an old version of the driver.

We have plenty of new stock of these cables which are guaranteed to run the very latest version of FTDI drivers.

Need a TTL-232R-5V-WE? Just cut the connector off this one.

If for any reason there is no Voltage label on the cable, then the above pictures show you how to identify them. The plastic inside the connector housing will be black for 3.3 Volts, and white for 5 Volts.

You can also test the voltage by plugging the unit into a USB port and measuring the voltage between Ground and any data pin.

The TTL-232R uses a FT232RQ device which is housed inside the USB 'A' connector, and is terminated at the end of a 1.8 meter cable with a 0.1" pitch header socket which provided access to transmit (Tx), receive (Rx), RTS#, CTS#, Vcc (5V), and GND.

Re: USB/Serial cable for EQMOD/ASCOM software and Skywatcher NEQ6Pro mount

Hi Don All good - thanks! I have successfully used your cable to connect my Win 7 laptop to my Skywatcher EQ6Pro mount.
All I needed to do was replace the 6-way header plug with a DB9 male plug.
I connected the Black lead to DB9 pins 4 & 5, The Orange lead to pin 6 and the Yellow lead to pin 9.
It works perfectly! You may even wish to include that info on the TTL-232R-5V USB converter page?
Thanks and kind regards JOHN COOPER
